@chapter Building the GNU C/C++ Cross Compiler Toolset
|
|
|
|
This chapter describes the steps required to acquire the
|
|
source code for a GNU cross compiler toolset, apply
|
|
any required RTEMS specific patches, compile that
|
|
toolset and install it.
|
|
|
|
@section Create the Archive and Build Directories
|
|
|
|
Start by making the @code{archive} directory to contain the downloaded
|
|
source code and the @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
|
|
@c @html
|
|
@c <IMG SRC="sfile12c.jpg" WIDTH=417 HEIGHT=178
|
|
@c ALT="Starting Directory Organization">
|
|
@c @end html
|
|
@c @end ifset
|
|
|
|
@section Get All the Pieces
|
|
|
|
This section lists the components of an RTEMS cross development system.
|
|
Included are the locations of each component as well as any required RTEMS
|
|
specific patches.

@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{GCC-TAR}
|
|
tar xzf ../archive/@value{BINUTILS-TAR}
|
|
tar xzf ../archive/@value{NEWLIB-TAR}
|
|
@end example
|
|
|
|
After the compressed tar files have been unpacked, the following
|
|
directories will have been created under tools.
|
|
|
|
@itemize @bullet
|
|
@item @value{BINUTILS-UNTAR}
|
|
@item @value{GCC-UNTAR}
|
|
@item @value{NEWLIB-UNTAR}
|
|
@end itemize
|
|
|
|
Copy the @code{bit} script from the @code{archive} directory
|
|
to the @code{tools} directory as shown below:
|
|
|
|
@example
|
|
cp ../archive/bit .
|
|
@end example
|
|
|
|
When the @code{bit} script is executed later in this process,
|
|
it will automatically create two other subdirectories:
|
|
|
|
@itemize @bullet
|
|
@item src
|
|
@item build-$@{CPU@}-tools
|
|
@end itemize
|
|
|
|
@itemize @bullet
|
|
@item src
|
|
@item build-$@{CPU@}-tools
|
|
@end itemize
|
|
|
|
The tree should look something like the following figure:
|
|
|
|
@example
|
|
@group
|
|
/whatever/prefix/you/choose/
|
|
bit
|

@section Reading the Tools Documentation
|
|
|
|
Each of the tools in the GNU development suite comes with documentation.
|
|
It is in the reader's and tool maintainers' interest that one read the
|
|
documentation before posting a problem to a mailing list or news group.

@section Modify the bit Script
|
|
|
|
Copy the @code{bit} script from @code{archive} to the tools directory.
|
|
|
|
Edit the @code{bit} file to alter the following environmental variables:
|
|
|
|
@itemize @bullet
|
|
@item INSTALL_POINT
|
|
@item BINUTILS
|
|
@item NEWLIB
|
|
@item GCC
|
|
@item BUILD_DOCS
|
|
@item BUILD_OTHER_LANGUAGES
|
|
@end itemize
|
|
|
|
These variables are located in the script section that resembles the
|
|
extract below:
|
|
|
|
|
|
@example
|
|
# USERCHANGE -- localize these.
|
|
#
|
|
# INSTALL_POINT: Directory tools are installed into.
|
|
# Recommended installation point for various OS's:
|
|
# Linux: /usr/local/rtems
|
|
# Solaris: /opt/gnu/rtems
|
|
# BINUTILS: Binutils source directory
|
|
# NEWLIB: Newlib source directory
|
|
# GCC: Newlib source directory
|
|
# BUILD_DOCS: Set to "yes" if you want to install documentation.
|
|
# BUILD_OTHER_LANGUAGES:
|
|
# Set to "yes" if you want to build Fortran and Objective-C
|
|
#
|
|
BINUTILS=@value{BINUTILS-UNTAR}
|
|
GCC=@value{GCC-UNTAR}
|
|
NEWLIB=@value{NEWLIB-UNTAR}
|
|
BUILD_DOCS=yes
|
|
BUILD_OTHER_LANGUAGES=yes
|
|
INSTALL_POINT=/home/joel/$@{GCC@}/$@{target@}
|
|
|
|
# USERCHANGE - uncomment this if you want to watch the commands.
|
|
@end example
|
|
|
|
Where each of the variables which may be modified is 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 egcs 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{BINUTILS-UNTAR}.
|
|
For example:
|
|
|
|
@example
|
|
BINUTILS=@value{BINUTILS-UNTAR}
|
|
@end example
|
|
|
|
@item GCC
|
|
is the directory under tools that contains @value{GCC-UNTAR}.
|
|
For example,
|
|
|
|
@example
|
|
GCC=@value{GCC-UNTAR}
|
|
@end example
|
|
|
|
@item NEWLIB
|
|
is the directory under tools that contains @value{NEWLIB-UNTAR}.
|
|
For example:
|
|
|
|
@example
|
|
NEWLIB=@value{NEWLIB-UNTAR}
|
|
@end example
|
|
|
|
@item BUILD_DOCS
|
|
is set to "yes" if you want to install documentation.
|
|
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, this enables Fortan and Objective-C.
|
|
For example:
|
|
|
|
@example
|
|
BUILD_OTHER_LANGUAGES=yes
|
|
@end example
|
|
|
|
@end table
|
|
|
|
@section Running the bit Script
|
|
|
|
After the @code{bit} script has been modified to reflect the
|
|
local installation, the modified @code{bit} script is run
|
|
using the following sequence:
|
|
|
|
@example
|
|
cd tools
|
|
./bit <target configuration>
|
|
@end example
|
|
|
|
Where <target configuration> is one of the following:
|
|
|
|
@itemize @bullet
|
|
@item hppa1.1
|
|
@item i386
|
|
@item i386-elf
|
|
@item i386-go32
|
|
@item i960
|
|
@item m68k
|
|
@item mips64orion
|
|
@item powerpc
|
|
@item sh
|
|
@item sparc
|
|
@end itemize
|
|
|
|
If no errors are encountered, the @code{bit} 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} script successfully completes, then the
|
|
GNU C/C++ cross compilation tools are installed.
|
|
|
|
If the @code{bit} script does not successfully complete, then investigation
|
|
will be required to determine the source of the error.
|
