Ubuntu – How to cross compile for ARM

armcompilinggccraspberrypi

How do I set up GCC for cross compiling for the ARM processor? The host would be on x86_64 ( AMD64 – Ubuntu 12.04 ) and the target would be ARM (Raspberry Pi as well as Pandaboard – will do separate compilations for each)?

Install gcc-arm-linux-gnueabi and binutils-arm-linux-gnueabi packages, and then just use arm-linux-gnueabi-gcc instead of gcc for compilation.

You need to be careful on what flavour of linux and binutils you have on your target system. The newest stuff is hardfloat, in this case you would do:

sudo apt-get install gcc-arm-linux-gnueabihf

This brings in the complete cross-compile environment, including binutils.

For using this GCC in the build process write:

CC=arm-linux-gnueabihf-gcc make
