This section provides information on installing and removing RPMs.
@subsection Installing RPMs
Note that RTEMS tools for multiple major versions of RTEMS can be
installed in parallel since they are installed into different host
directories. The tools also include the RTEMS Release Series in their
name.
The following is a sample session illustrating the installation
of a C/C++ toolset targeting the SPARC architecture.
@subsection Locating the RPMs for your GNU/Linux Distribution
The RTEMS Project maintains a Yum Repository of RPMs for its
toolsets. Whether you use Yum to install the RPMs or download and install
them via another procedure, you will need to locate the appropriate
set of RPMs on the RTEMS Yum Repository. The following instructions
are generalized.
If your host operating system uses Yum and RPMs, then you will only have
to download and install two RPMs by hand
@enumerate
@item Point your browser at
@uref{http://www.rtems.org/ftp/pub/rtems/linux,
http://www.rtems.org/ftp/pub/rtems/linux}. In this directory, you
will see a list of RTEMS major versions such as 4.11, 4.10, 4.9, etc..
Descend into the appropriate directory for the version of RTEMS you
are using.
@item Now that you are in the directory for a specific RTEMS major
version, you will be presented with a list of GNU/Linux distributions.
This will include options like redhat, centos, fedora, and suse.
Select the appropriate distribution.
@item Now that you are in the directory for your selected distribution,
you will be presented with a list of distribution versions for which
RTEMS pre-built RPMs are available. Select the appropriate distribution
version.
@item Now that you are in the directory for the proper version of
your selected distribution, you will be presented with a choice of
host architecture versions such as i386, i686, and x86_64. Select the
appropriate version for your development computer.
@item At this point, you will have a long list of RPMs to select from.
@end enumerate
The RTEMS Projects supports a wide variety of host OS and target
combinations. In addition, these toolsets are specific to a particular
RTEMS Release Series. Given the large number of possible combinations,
the instructions use variables to indicate where versions go in the real
package names you will use. These variable are used in the examples of
RPM version names:
@itemize @bullet
@item @code{<VERSION>} is the tool version will be found at this location
in the RPM name. This will be a release number such as @code{2.20}
or @code{4.4.5}.
@item @code{<DIST>} indicates the GNU/Linux distribution version.
This will be a string such as @code{fc14} or @code{el6}.
@item @code{<ARCH>} indicates the architecture used for RPMs on your
GNU/Linux installation. This will be a string such as @code{i386}
or @code{x86_64}.
@item @code{<RPM>} indicates the RPM revision level. This will be a
single integer.
@end itemize
The tool VERSION and RPM release may vary within the set of current RPMs for a particular RTEMS Release series based upon the target architecture.
If you are using Yum, please continue to the next section. If you are
downloading the RPMs to install by hand, then go to the @ref{Installing
RPMs Without Yum} section.
@subsection Managing RPMs Using Yum
This section describes how to install and remove RTEMS Toolsets using Yum.
@subsubsection Installing RPMs Using Yum
If you are on a host operating system that uses Yum, you are fortunate because this is the one of the simplest ways to install the tools. After locating the appropriate directory on the RTEMS Yum Repository using the instructions in @ref{Locating the RPMs for your GNU/Linux Distribution}, you will need to install the following RPMs:
@itemize @bullet
@item @value{RTEMSRPMPREFIX}-release-<VERSION>-<RPM>.<DIST>.noarch.rpm
@item @value{RTEMSRPMPREFIX}-yum-conf-<VERSION>-<RPM>.<DIST>.noarch.rpm
@end itemize
You can use the search within page feature of your browser to locate
the RPMs with "release" or "yum" in their names.
You will need to download the RPMs above or RPM can be given the URLs for
them and it will fetch them for you. Either way, the commands similar
to the following will install the common or base RPMs required.
@example
rpm -U @value{RTEMSRPMPREFIX}binutils-common-@value{BINUTILSVERSION}-@value{BINUTILSRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-binutils-@value{BINUTILSVERSION}-@value{BINUTILSRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}gcc-common-@value{GCCVERSION}-@value{GCCRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-newlib-@value{NEWLIBVERSION}-@value{GCCRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gcc-@value{GCCVERSION}-@value{GCCRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gcc-c++-@value{GCCVERSION}-@value{GCCRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}gdb-common-@value{GDBVERSION}-@value{GDBRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gdb-@value{GDBVERSION}-@value{GDBRPMRELEASE}.i386.rpm
rpm -U @value{RTEMSRPMPREFIX}-release-<VERSION>-<RPM>.<DIST>.noarch.rpm \
@value{RTEMSRPMPREFIX}-yum-conf-<VERSION>-<RPM>.<DIST>.noarch.rpm
@end example
Upon successful completion of the above command sequence, a
C/C++ cross development toolset targeting the SPARC is
installed in @code{@value{RTEMSPREFIX}}. In order to use this toolset,
the directory @code{@value{RTEMSPREFIX}/bin} must be included in your
PATH.
Once these are installed, Yum knows about the RTEMS Yum repository
for @value{RTEMSPREFIX}. This means that you can install and upgrade
RTEMS Toolsets just like the packages provided by your distribution.
To install complete C and C++ toolset targeting the SPARC architecture
for the RTEMS @value{RTEMSAPI} Release series, commands similar to the
following will be used.
Once you have successfully installed the RPMs for BINUTILS, GCC,
NEWLIB, and GDB, then you may proceed directly to @ref{Building RTEMS}.
@example
yum install @value{RTEMSPREFIX}-auto*
yum install @value{RTEMSPREFIX}-sparc-*
@end example
The first command installs GNU autoconf and automake which are used
by all RTEMS targets. The second command installs the complete
sparc-@value{RTEMSPREFIX} toolset including all dependencies.
@subsubsection Removing RPMs Using Yum
The following is a sample session illustrating the removal of a C/C++
toolset targeting the SPARC architecture.
@example
yum erase @value{RTEMSRPMPREFIX}-sparc-*
@end example
If this is the last target architecture for which tools are installed, then you can remove the RTEMS GNU autotools and common packages as follows:
@example
yum erase @value{RTEMSRPMPREFIX}-auto*
yum erase @value{RTEMSRPMPREFIX}-*common*
@end example
NOTE: If you have installed any RTEMS BSPs, then it is likely that RPM
will complain about not being able to remove everything. These will
have to be removed by hand.
@subsection Managing RPMs Without Using Yum
This section describes how to install and remove RTEMS Toolsets without
using Yum. This is NOT expected to be the norm for RPM users.
@subsubsection Installing RPMs Without Yum
The following is a sample session illustrating the installation of the
complete C and C++ toolset targeting the SPARC architecture for the
RTEMS @value{RTEMSAPI} Release series.
Since you are not using Yum, you will need to download all of the RPMs
you will install. Alternatively, RPM can be given a URL for an RPM file
and it will fetch it for you. Either way, the commands similar to the
following will install the common or base RPMs required.
@example
rpm -U @value{RTEMSRPMPREFIX}binutils-common-<VERSION>-<RPM>.<DIST>.noarch.rpm \
@value{RTEMSRPMPREFIX}gcc-common-<VERSION>-<RPM>.<DIST>.noarch.rpm \
@value{RTEMSRPMPREFIX}newlib-common-<VERSION>-<RPM>.<DIST>.noarch.rpm \
@value{RTEMSRPMPREFIX}gdb-common-<VERSION>-<RPM>.<DIST>.noarch.rpm
@end example
The above RPMs are shared across all RTEMS targets and include common
files such as the documentation. The following illustrates how to install
the GNU Autoconf and Automake RPMs that match your RTEMS installation.
RTEMS uses the GNU Autotools for its configure and build infrastructure
and you will need these if you modify the build infrastructure or check
out RTEMS from CVS and have to bootstrap the source tree.
@example
rpm -U @value{RTEMSRPMPREFIX}autoconf-<VERSION>-<RPM>.<DIST>.noarch.rpm \
@value{RTEMSRPMPREFIX}automake-<VERSION>-<RPM>.<DIST>.noarch.rpm
@end example
Now that you have installed all of the RPMs that are independent of the
target architecture you can install the C toolset for a specific target.
The following command will install the target architecture specific set
of the RPMs for a C toolset including GDB.
@example
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-binutils-<VERSION>-<RPM>.<ARCH>.rpm \
@value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gcc-<VERSION>-<RPM>.<ARCH>.rpm \
@value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-newlib-<VERSION>-<RPM>.<ARCH>.rpm \
@value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-libgcc-<VERSION>-<RPM>.<ARCH>.rpm \
@value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gdb-<VERSION>-<RPM>.<ARCH>.rpm
@end example
The following command illustrates how to install the C++ specific portion of the RPMs.
@example
rpm -U @value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-gcc-c++-<VERSION>-<RPM>.<ARCH>.rpm \
@value{RTEMSRPMPREFIX}sparc-rtems@value{RTEMSAPI}-libstd++-<VERSION>-<RPM>.<ARCH>.rpm
@end example
Upon successful completion of the above command sequence, a C/C++
cross development toolset targeting the SPARC is installed in
@code{@value{RTEMSPREFIX}}. In order to use this toolset, the directory
@code{@value{RTEMSPREFIX}/bin} should be at the start of your PATH.
At this point, the tools are installed for a specific target architecture
adn you may proceed directly to @ref{Building RTEMS}.
If you want to build RTEMS for multiple target architectures, you will
need to install the target specific portion of the RPMs for each target.
@subsubsection Removing RPMs Without Using Yum
The following is a sample session illustrating the removal of a C/C++
toolset targeting the SPARC architecture.
@example
rpm -e `rpm -qa | grep @value{RTEMSRPMPREFIX}-sparc-`
@end example
If this is the last target architecture for which tools are installed, then you can remove the RTEMS GNU autotools and common packages as follows:
@example
rpm -e `rpm -qa | grep @value{RTEMSRPMPREFIX}-auto`
rpm -e `rpm -qa | grep @value{RTEMSRPMPREFIX} | grep common`
@end example
NOTE: If you have installed any RTEMS BSPs, then it is likely that RPM
will complain about not being able to remove everything. These will
have to be removed by hand.

@section Archive and Build Directories
@subsection GNU/Linux Distrobutions using Debian Packaging Format
If you are using RPM or another packaging format that supports
building a package from source, then there is probably a directory
structure assumed by that packaging format. Otherwise, you
are free to use whatever organization you like. However, this
document will use the directory organization described
in @ref{Archive and Build Directory Format}.
@subsection RPM Archive and Build Directory Format
For RPM, it is assumed that the following subdirectories
are under a root directory such as @code{/usr/src/redhat}:
@example
BUILD
RPMS
SOURCES
SPECS
SRPMS
@end example
For the purposes of this document, the RPM @code{SOURCES} directory
is the directory into which all tool source and patches are
assumed to reside. The @code{BUILD} directory is where the actual
build is performed when building binaries from a source RPM.
The @code{SOURCES} and @code{BUILD} are logically equivalent to
the @code{archive} and @code{tools} directory discussed in the
next section.
@subsection Archive and Build Directory Format
When no packaging format requirements are present, the root directory for
the storage of source archives and patches as well as for building the
tools is up to the user. The only concern is that there be enough
disk space to complete the build. In this document, the following
organization will be used.
Make an @code{archive} directory to contain the downloaded
source code and a @code{tools} directory to be used as a build
directory. The command sequence to do this is shown
below:
@example
mkdir archive
mkdir tools
@end example
This will result in an initial directory structure similar to the
one shown in the following figure:
@example
@group
/whatever/prefix/you/choose/
archive/
tools/
@end group
@end example
@c @ifset use-html

The RTEMS Project does not currently provide prebuilt toolsets in the Debian packaging format used by the Debian and Ubuntu distributions. If you are using a distribution using this packaging format, then you have two options for installing the RTEMS toolset.
The first option is to build the toolset from source following the instructions in the @ref{Building the GNU Cross Compiler Toolset}. This is an approach taken by many users.
Alternatively, it is often possible to extract the contents of the RPM files which contain the portions of the toolset you require. In this case, you will follow the instructions in @ref{Locating the RPMs for your GNU/Linux Distribution} but assume your distribution is the RedHat Enterprise Linux version which is closest to yours from a shared library perspective. As of December 2010, this is usually RedHat Enterprise Linux version 5. As time passes, it is expected that version 6 will be appropriate in more cases. You will extract the contents of these RPM files using either @code{rpm2cpio} and install them or you may be able to use the @code{alien} tool to convert them to Debian packaging.

@section Unarchiving the Tools
While in the @code{tools} directory, unpack the compressed
tar files using the following command sequence:
@example
cd tools

tar xzf ../archive/@value{GNAT-TAR}
tar xzf ../archive/@value{BINUTILSTAR}
tar xzf ../archive/@value{NEWLIBTAR}

@end example
After the compressed tar files have been unpacked, the following
directories will have been created under tools.
@itemize @bullet
@item @value{BINUTILSUNTAR}
@item @value{GCCUNTAR}
@item @value{GNAT-UNTAR}
@item @value{NEWLIBUNTAR}
@end itemize
There will also be a set of scripts in the current directory
which aid in building the tools and RTEMS. They are:
@itemize @bullet
@item bit_ada
@item bit_gdb
@item bit_rtems
@item common.sh
@item user.cfg
@end itemize
When the @code{bit_ada} script is executed later in this process,
it will automatically create two other subdirectories:
@itemize @bullet
@item src
@item build-$@{CPU@}-tools
@end itemize
Similarly, the @code{bit_gdb} script will create the
subdirectory @code{build-$@{CPU@}-gdb} and
the @code{bit_rtems} script will create the
subdirectory @code{build-$@{CPU@}-rtems}.
The directory tree should look something like the following figure:

@c Localizing the Configuration
@c
@section Localizing the Configuration
Edit the @code{user.cfg} file to alter the settings of various
variables which are used to tailor the build process.
Each of the variables set in @code{user.cfg} may be modified
as described below:
@table @code
@item INSTALL_POINT
is the location where you wish the GNU C/C++ cross compilation tools for
RTEMS to be built. It is recommended that the directory chosen to receive
these tools be named so that it is clear from which gcc distribution it
was generated and for which target system the tools are to produce code for.
@b{WARNING}: The @code{INSTALL_POINT} should not be a subdirectory
under the build directory. The build directory will be removed
automatically upon successful completion of the build procedure.
@item BINUTILS
is the directory under tools that contains @value{BINUTILSUNTAR}.
For example:
@example
BINUTILS=@value{BINUTILSUNTAR}
@end example
@item GCC
is the directory under tools that contains @value{GCCUNTAR}.
For example,
@example
GCC=@value{GCCUNTAR}
@end example
Note that the gnat version is not needed because the gnat source
is built as part of building gcc.
@item NEWLIB
is the directory under tools that contains @value{NEWLIBUNTAR}.
For example:
@example
NEWLIB=@value{NEWLIBUNTAR}
@end example
@item BUILD_DOCS
is set to "yes" if you want to install documentation. This requires
that tools supporting documentation production be installed. This
currently is limited to the GNU texinfo package.
For example:
@example
BUILD_DOCS=yes
@end example
@item BUILD_OTHER_LANGUAGES
is set to "yes" if you want to build languages other than C and C++. At
the current time, the set of alternative languages includes Java, Fortran,
and Objective-C. These alternative languages do not always build cross.
Hence this option defaults to "no".
For example:
@example
BUILD_OTHER_LANGUAGES=yes
@end example
@b{NOTE:} Based upon the version of the compiler being used, it may not
be possible to build languages other than C and C++ cross. In many cases,
the language run-time support libraries are not "multilib'ed". Thus the
executable code in these libraries will be for the default compiler settings
and not necessarily be correct for your CPU model.
@item RTEMS
is the directory under tools that contails @value{RTEMSUNTAR}.
@item ENABLE_RTEMS_POSIX
is set to "yes" if you want to enable the RTEMS POSIX API support.
At this time, this feature is not supported by the UNIX ports of RTEMS
and is forced to "no" for those targets. This corresponds to the
@code{configure} option @code{--enable-posix}.
This must be enabled to support the GNAT/RTEMS run-time.
@item ENABLE_RTEMS_ITRON
is set to "yes" if you want to enable the RTEMS ITRON API support.
At this time, this feature is not supported by the UNIX ports of RTEMS
and is forced to "no" for those targets. This corresponds to the
@code{configure} option @code{--enable-itron}.
@item ENABLE_RTEMS_MP
is set to "yes" if you want to enable the RTEMS multiprocessing
support. This feature is not supported by all RTEMS BSPs and
is automatically forced to "no" for those BSPs. This corresponds to the
@code{configure} option @code{--enable-multiprocessing}.
@item ENABLE_RTEMS_CXX
is set to "yes" if you want to build the RTEMS C++ support including
the C++ Wrapper for the Classic API. This corresponds to the
@code{configure} option @code{--enable-cxx}.
@item ENABLE_RTEMS_TESTS
is set to "yes" if you want to build the RTEMS Test Suite. If this
is set to "no", then only the Sample Tests will be built. Setting
this option to "yes" significantly increases the amount of disk
space required to build RTEMS.
This corresponds to the @code{configure} option @code{--enable-tests}.
@item ENABLE_RTEMS_TCPIP
is set to "yes" if you want to build the RTEMS TCP/IP Stack. If a
particular BSP does not support TCP/IP, then this feature is automatically
disabled. This corresponds to the @code{configure} option
@code{--enable-tcpip}.
@item ENABLE_RTEMS_NONDEBUG
is set to "yes" if you want to build RTEMS in a fully optimized
state. This corresponds to executing @code{make} after configuring
the source tree.
@item ENABLE_RTEMS_DEBUG
is set to "yes" if you want to build RTEMS in a debug version.
When built for debug, RTEMS will include run-time code to
perform consistency checks such as heap consistency checks.
Although the precise compilation arguments are BSP dependent,
the debug version of RTEMS is usually built at a lower optimization
level. This is usually done to reduce inlining which can make
tracing code execution difficult. This corresponds to executing
@code{make VARIANT=debug} after configuring
the source tree.
@item INSTALL_RTEMS
is set to "yes" if you want to install RTEMS after building it.
This corresponds to executing @code{make install} after configuring
and building the source tree.
@item ENABLE_RTEMS_MAINTAINER_MODE
is set to "yes" if you want to enabled maintainer mode functionality
in the RTEMS Makefile. This is disabled by default and it is not
expected that most users will want to enable this. When this option
is enabled, the build process may attempt to regenerate files that
require tools not required when this option is disabled.
This corresponds to the @code{configure} option
@code{--enable-maintainer-mode}.
@end table
@section Running the bit_ada Script
After the @code{bit_ada} script has been modified to reflect the
local installation, the modified @code{bit_ada} script is run
using the following sequence:
@example
cd tools
./bit_ada <target configuration>
@end example
Where <target configuration> is one of the following:
@itemize @bullet
@item hppa1.1
@item i386
@item m68k
@item powerpc
@item sh
@item sparc
@end itemize
NOTE: The above list of target configurations is the list of RTEMS supported
targets. Only a subset of these have been tested with GNAT/RTEMS. For more
information, contact your GNAT/RTEMS representative.
The build process can take a while to complete. Many users find it
handy to run the build process in the background, capture the output
in a file, and monitor the output. This can be done as follows:
@example
./bit_ada <target configuration> >bit.log 2>&1 &
tail -f bit.log
@end example
If no errors are encountered, the @code{bit_ada} script will conclude by
printing messages similar to the following:
@example
The src and build-i386-tools subdirectory may now be removed.
Started: Fri Apr 10 10:14:07 CDT 1998
Finished: Fri Apr 10 12:01:33 CDT 1998
@end example
If the @code{bit_ada} script successfully completes, then the
GNU C/C++ cross compilation tools are installed.
If the @code{bit_ada} script does not successfully complete, then investigation
will be required to determine the source of the error.

@c Common Problems
@c
@section Common Problems
@subsection Error Message Indicates Invalid Option to Assembler
If a message like this is printed then the new cross compiler
is most likely using the native assembler instead of the cross
assembler or vice-versa (native compiler using new cross assembler).
This can occur for one of the following reasons:
@itemize @bullet
@item Binutils Patch Improperly Applied
@item Binutils Not Built
@item Current Directory is in Your PATH
@end itemize
If you are using binutils 2.9.1 or newer with certain older versions of
gcc, they do not agree on what the name of the newly
generated cross assembler is. Older binutils called it @code{as.new}
which became @code{as.new.exe} under Windows. This is not a valid
file name, so @code{as.new} is now called @code{as-new}. By using the latest
released tool versions and RTEMS patches, this problem will be avoided.
If binutils did not successfully build the cross assembler, then
the new cross gcc (@code{xgcc}) used to build the libraries can not
find it. Make sure the build of the binutils succeeded.
If you include the current directory in your PATH, then there
is a chance that the native compiler will accidentally use
the new cross assembler instead of the native one. This usually
indicates that "." is before the standard system directories
in your PATH. As a general rule, including "." in your PATH
is a security risk and should be avoided. Remove "." from
your PATH.
NOTE: In some environments, it may be difficult to remove "."
completely from your PATH. In this case, make sure that "."
is after the system directories containing "as" and "ld".
@subsection Error Messages Indicating Configuration Problems
If you see error messages like the following,
@itemize @bullet
@item cannot configure libiberty
@item coff-emulation not found
@item etc.
@end itemize
Then it is likely that one or more of your gnu tools is
already configured locally in its source tree. You can check
for this by searching for the @code{config.status} file
in the various tool source trees. The following command
does this for the binutils source:
@example
find @value{BINUTILSUNTAR} -name config.status -print
@end example
The solution for this is to execute the command
@code{make distclean} in each of the GNU tools
root source directory. This should remove all
generated files including Makefiles.
This situation usually occurs when you have previously
built the tool source for some non-RTEMS target. The
generated configuration specific files are still in
the source tree and the include path specified during
the RTEMS build accidentally picks up the previous
configuration. The include path used is something like
this:
@example
-I../../@value{BINUTILSUNTAR}/gcc -I/@value{BINUTILSUNTAR}/gcc/include -I.
@end example
Note that the tool source directory is searched before the
build directory.
This situation can be avoided entirely by never using
the source tree as the build directory -- even for

@chapter Introduction
The purpose of this document is to guide you through the process of
installing a GNU cross development environment to use with RTEMS.
If you are already familiar with the concepts behind a cross compiler and
have a background in Unix, these instructions should provide the bare
essentials for performing a setup of the following items:
@itemize @bullet
@item GNAT/RTEMS Cross Compilation Tools on your host system
@item RTEMS OS for the target host
@item GDB Debugger
@end itemize
The remainder of this chapter provides background information on real-time
embedded systems and cross development and an overview of other
resources of interest on the Internet. If you are not familiar with
real-time embedded systems or the other areas, please read those sections.
These sections will help familiarize you with the
types of systems RTEMS is designed to be used in and the cross development
process used when developing RTEMS applications.
@section Real-Time Embedded Systems
Real-time embedded systems are found in practically every facet of our
everyday lives. Today's systems range from the common telephone, automobile
control systems, and kitchen appliances to complex air traffic control
systems, military weapon systems, an d production line control including
robotics and automation. However, in the current climate of rapidly changing
technology, it is difficult to reach a consensus on the definition of a
real-time embedded system. Hardware costs are continuing to rapidly decline
while at the same time the hardware is increasing in power and functionality.
As a result, embedded systems that were not considered viable two years ago
are suddenly a cost effective solution. In this domain, it is not uncommon
for a single hardware configuration to employ a variety of architectures and
technologies. Therefore, we shall define an embedded system as any computer
system that is built into a larger system consisting of multiple technologies
such as digital and analog electronics, mechanical devices, and sensors.
Even as hardware platforms become more powerful, most embedded systems are
critically dependent on the real-time software embedded in the systems
themselves. Regardless of how efficiently the hardware operates, the
performance of the embedded real-time software determines the success of the
system. As the complexity of the embedded hardware platform grows, so does
the size and complexity of the embedded software. Software systems must
routinely perform activities which were only dreamed of a short time ago.
These large, complex, real-time embedded applications now commonly contain
one million lines of code or more.
Real-time embedded systems have a complex set of characteristics that
distinguish them from other software applications. Real-time embedded
systems are driven by and must respond to real world events while adhering to
rigorous requirements imposed by the environment with which they interact.
The correctness of the system depends not only on the results of
computations, but also on the time at which the results are produced. The
most important and complex characteristic of real-time application systems is
that they must receive and respond to a set of external stimuli within rigid
and critical time constraints.
A single real-time application can be composed of both soft and hard
real-time components. A typical example of a hard real-time system is a
nuclear reactor control system that must not only detect failures, but must
also respond quickly enough to prevent a meltdown. This application also has
soft real-time requirements because it may involve a man-machine interface.
Providing an interactive input to the control system is not as critical as
setting off an alarm to indicate a failure condition. However, th e
interactive system component must respond within an acceptable time limit to
allow the operator to interact efficiently with the control system.
@section Cross Development
Today almost all real-time embedded software systems are developed in a
@b{cross development} environment using cross development tools. In the cross
development environment, software development activities are typically
performed on one computer system, the @b{host} system, while the result of the
development effort (produced by the cross tools) is a software system that
executes on the @b{target} platform. The requirements for the target platform are
usually incompatible and quite often in direct conflict with the requirements
for the host. Moreover, the target hardware is often custom designed for a
particular project. This means that the cross development toolset must allow
the developer to customize the tools to address target specific run-time
issues. The toolset must have provisions for board dependent initialization
code, device drivers, and error handling code.
The host computer is optimized to support the code development cycle with
support for code editors, compilers, and linkers requiring large disk drives,
user development windows, and multiple developer connections. Thus the host
computer is typically a traditional UNIX workstation such as are available
from SUN or Silicon Graphics, or a PC running either a version of MS-Windows
or UNIX. The host system may also be required to execute office productivity
applications to allow the software developer to write documentation, make
presentations, or track the project's progress using a project management
tool. This necessitates that the host computer be general purpose with
resources such as a thirty-two or sixty-four bit processor, large amounts of
RAM, a monitor, mouse, keyboard, hard and floppy disk drives, CD-ROM drive,
and a graphics card. It is likely that the system will be multimedia capable
and have some networking capability.
Conversely, the target platform generally has limited traditional computer
resources. The hardware is designed for the particular functionality and
requirements of the embedded system and optimized to perform those tasks
effectively. Instead of hard driverss and keyboards, it is composed of
sensors, relays, and stepper motors. The per-unit cost of the target platform
is typically a critical concern. No hardware component is included without
being cost justified. As a result, the processor of the target system is
often from a different processor family than that of the host system and
usually has lower performance. In addition to the processor families
targeted only for use in embedded systems, there are versions of nearly every
general-purpose process or specifically tailored for real-time embedded
systems. For example, many of the processors targeting the embedded market
do not include hardware floating point units, but do include peripherals such
as timers, serial controllers, or network interfaces.

@chapter Requirements
A fairly large amount of disk space is required to perform the build of the
GNU C/C++ Cross Compiler Tools for RTEMS. The following table may help in
assessing the amount of disk space required for your installation:
@example
+------------------------------------+--------------------------+
| Component | Disk Space Required |
+------------------------------------+--------------------------+
| archive directory | 40 Mbytes |
| tools src unarchived | 200 Mbytes |
| each individual build directory | up to 500 Mbytes |
| each installation directory | 20-200 Mbytes |
+------------------------------------+--------------------------+
@end example
It is important to understand that the above requirements only address
the GNU C/C++ Cross Compiler Tools themselves. Adding additional
languages such as Fortran or Objective-C can increase the size
of the build and installation directories. Also, the unarchived
source and build directories can be removed after the tools are
installed.
After the tools themselves are installed, RTEMS must be built
and installed for each Board Support Package that you wish
to use. Thus the precise amount of disk space required
for each installation directory depends highly on the number
of RTEMS BSPs which are to be installed. If a single BSP is
installed, then the additional size of each install directory
will tend to be in the 40-60 Mbyte range.
There are a number of factors which must be taken into
account in oreder to estimate the amount of disk space required
to build RTEMS itself. Attempting to build multiple BSPs in
a single step increases the disk space requirements. Similarly
enabling optional features increases the build and install
space requirements. In particular, enabling and building
the RTEMS tests results in a significant increase in build
space requirements but since the test are not installed has
no impact on installation requirements.
The instructions in this manual should work on any computer running
a UNIX variant. Some native GNU tools are used by this procedure
including:
@itemize @bullet
@item GCC
@item GNAT
@item GNU make
@end itemize
In addition, some native utilities may be deficient for building
the GNU tools.
@section Native GNAT
The native GNAT must be installed in the default location or built
from source. No GCC or GNAT environment variables should be set during
the build or use of the cross GNAT/RTEMS toolset as this could result in
an unpredictable mix of native and cross toolsets.
Binaries for native GNAT installations are available at the primary
GNAT ftp site (@value{GNAT-FTP}. Installation instructions are
included with the binary GNAT distributions. The binary installation
should be installed in the default location or installed in a
non-default location and used ONLY to build a native GNAT from source.
This final native GNAT will be used to build the GNAT/RTEMS cross
development toolset.
@subsection Verifying Correct Operation of Native GNAT
It is imperative that the native GNAT installation work correctly for
the installation of GNAT/RTEMS to succeed. It is recommended that the
user verify that the native GNAT is installed correctly by performing
these tests:
@subsubsection Native Hello World Test
Place the following Ada source code in hello.adb:
@example
with Text_IO; use Text_IO;
procedure Hello is
begin
Put_Line ( "Hello World");
end Hello;
@end example
Use the following command sequence to ompile and execute the above program:
@example
gnatmake hello
./hello
@end example
If the message @code{Hello World} is printed, then the native installation
of GNAT operates well enough to proceed.
@subsubsection Insure GCC and GNAT Environment Variables Are Not Set
If any of the following commands produce output, then you have
environment variables overriding the default behavior of the
native GNAT toolset. These variables will conflict with the cross
toolset. Please resolve this problem before proceeding further.
@example
echo $GCC_EXEC_PREFIX
echo $ADA_INCLUDE_PATH
echo $ADA_OBJECTS_PATH
echo $LD_RUN_PATH
echo $C_INCLUDE_PATH
@end example

@chapter Building the Sample Application
@section Unpack the Sample Application
Use the following command to unarchive the sample application:
@example
cd tools
tar xzf ../archive/hello_world_ada.tgz
@end example
@section Create a BSP Specific Makefile
Provided are example Makefiles for multiple BSPs. Copy one of these to
the file Makefile.<BOARD_SUPPORT_PACKAGE> and edit it as appropriate for
your local configuration.
Use the <INSTALLATION_POINT> and <BOARD_SUPPORT_PACKAGE> specified when
configuring and installing RTEMS.
@section Build the Sample Application
Use the following command to start the build of the sample application:
@example
cd tools/hello_world_ada
make -f Makefile.<BOARD_SUPPORT_PACKAGE>
@end example
NOTE: GNU make is the preferred @code{make} utility. Other @code{make}
implementations may work but all testing is done with GNU make.
If the BSP specific modifications to the Makefile were correct and
no errors are detected during the sample application build, it is
reasonable to assume that the build of the GNAT/RTEMS Cross Compiler Tools
for RTEMS and RTEMS itself for the selected host and target
combination was done properly.
@section Application Executable
If the sample application has successfully been build, then the application
executable is placed in the following directory:
@example
tools/hello_world_ada/o-optimize/<filename>.exe
@end example
How this executable is downloaded to the target board is very dependent
on the BOARD_SUPPORT_PACKAGE selected.
