RTEMS Release Notes
This sections describes how to build and install the FSF GNU tools for use as a cross-compilation system. These tools are used by the RTEMS developers. Every effort has been made to make these instructions accurate and complete. However, it is recommended that the individual doing the installation read the appropriate installation notes for each of the tools in the cross toolset. This will help insure that there are no special requirements for a particular host.
If the host and target processors are the same, then it may be possible to use the host development tools. An example of this scenario is using a SPARC based workstation to develop an RTEMS application for the SPARC processor. Although the native toolset is useable in this scenario, it is ultimately more desirable to build a toolset specifically for the embedded environment.
Instructions for building a cross environment using the GNU tools is provided in the crossgcc FAQ available from ftp.cygnus.com in /pub/embedded/crossgcc. It is recommended that the user following these instructions.
After the cross development toolset has been built and installed, it will be necessary to modify the environment of each RTEMS application developer to reflect at least the path of the newly installed cross development toolset.
The documentation for the FSF GNU and Cygnus tools is formatted using TeX. The RTEMS developers use TeX 3.14t3 to format the manuals for their own use. This document does not contain instructions on the acquisition or installation of TeX and supporting tools.
NOTE: For "UNIX" processors, the native compiler binary utilities should be used.
