How do I set up GCC for cross compiling for the ARM processor? The host would be on x68 ( 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.

On Ubuntu 13.10 you get gcc-4.7 for 'gnueabi' and gcc-4.8 for 'gnueabihf'. – nobar Feb 23 '14 at 23:34
    
when I tried to compile I got openssl/ossl_typ.h not found error though I already installed libssl-dev. – neckTwi Sep 10 '14 at 18:36

If you get source code from apt-get source, after apt-get build-dep you can normally just compile with dpkg-buildpackage -b -uc -us -r Is there a way to build a .deb this easily for ARM without changing the makefile? – Jonathan Leaders Dec 28 '14 at 4:39
    
@Maratyszcza could you please be more specific regarding the execution of line and then just use arm-linux-gnueabi-gcc instead of gcc for compilation? When I compile I use a call to make which, AFAIK, naturally points to /usr/lib/gcc or something close to that. How could I call arm-linux-gnueabi-gcc directly? – Momergil Nov 26 '15 at 17:01
