Appendix 3. Building the GNU Software Tools
This appendix shows how to build the ARM-targeted (arm-elf) GNU software tools (gcc, binutils, gdb, newlib) used in this book. The instructions are for both Windows (running Cygwin) and Linux host operating systems.
Warning
Unless there is some specific reason for building a new set of GNU tools, we recommend you use the prebuilt GNU binaries provided on the bookâs web site and included on the Arcom boardâs CD-ROM. The installation of the prebuilt tools is covered in Appendix B and Appendix E, respectively.
Approximately 1.2 GB of disk space is needed for the GNU tools source code and build output directories. These instructions are adapted from the web page âBuilding a toolchain for use with eCos,â found online at http://ecos.sourceware.org.
Another popular site for building cross development tools is found online at http://kegel.com/crosstool. This site contains instructions and numerous scripts for building various GNU cross development tool chains for various processors and host systems. You might find that the tools on this site suit your needs better.
The following steps should be followed at a bash shell prompt in Cygwin or a terminal in Linux. We built the GNU tools under Windows XP (SP2) and Linux Fedora Core 5. These instructions locate the GNU toolsâ source code under the /src directory, the build output under /tmp/build, and the resulting GNU tools under /opt/gnutools. In Windows, all of these subdirectories are contained ...
