I'm guessing you don't have your PATH set up correctly. You should
export a symbol for your cross compiler location and prefix rather than
modifying the makefile. The following is what I use:
export PATH=$PATH:/opt/eldk/usr/bin/
export CROSS_COMPILE=powerpc-linux-
export ARCH=ppc
After doing this, make will invoke the proper cross compiler. Obviously,
1) Your configuration may be different
2) If you put the above in a script file, you must use the bash command
"source" to run it in your current shell. If you type the script file
at the command line, it will run in a spawned shell and the exported
symbols will be gone when the spawned shell exists (not what you want!).
Best regards,
gvb
