Tool Chain

You would first need to get cross compile tools from:
http://www.handhelds.org/download/projects/toolchain/
Download arm-linux-gcc-3.3.2.tar.bz2
Create a directory /usr/local/arm
Extract the file cross-3.3.2.tar.gz after changing the current directory to / .
The tool chain will be extracted to /usr/local/arm, and includes the compiler, include files, libraries etc.
Add the path /usr/local/arm/3.3.2/bin in the PATH variable
Compilation can now be done using the compiler arm-linux-gcc
Project make files may need to be edited to use arm-linux-gcc
