@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 | 30 Mbytes |
| tools src unzipped | 100 Mbytes |
| each individual build directory | 300 Mbytes worst case |
| each installation directory | 20-400 Mbytes |
+------------------------------------+--------------------------+
@end example
The disk space required for each installation directory depends
primarily on the number of RTEMS BSPs which are to be installed.
If a single BSP is installed, then the size of each install directory
will tend to be in the 40-60 Mbyte range.
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
