- Makefiles are setup for cross-compilation using custom toolchains. File <code class="filename">make.def</code>, in the main toolkit folder, defines cross-comilation symbols referenced in lower-level makefiles. Lower-level makefiles include <code class="filename">make.def</code> before building their targets. The following is an example <code class="filename">make.def</code> file used when cross-compiling for the ADM5120 MIPSEL-based gateway.

- Developers are encouraged to make changes in this file rather than adding additional variables to the lower-level makefiles. For example, you can edit variable <code class="varname">BIN</code> to install toolkit programs in some location other than <code class="filename">/usr/local/bin</code> or variable <code class="varname">WWW</code> to install <acronym class="acronym">HTML</acronym> documentation on your local website.
