@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 | 35 Mbytes |
|
|
| tools src unarchived | 150 Mbytes |
|
|
| each individual build directory | 300 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 GNU make
|
|
@item GNU makeinfo
|
|
@end itemize
|
|
|
|
In addition, some native utilities may be deficient for building
|
|
the GNU tools.

@section GNU makeinfo Version Requirements
|
|
|
|
In order to build egcs 1.1b or newer, the GNU @code{makeinfo} program
|
|
installed on your system must be at least version 1.68. The appropriate
|
|
version of @code{makeinfo} is distributed with egcs 1.1b.
|
|
|
|
The following demonstrates how to determine the version of @code{makeinfo}
|
|
on your machine:
|
|
|
|
@example
|
|
makeinfo --version
|
|
@end example
