We are using Linaro gcc armhf cross compiler, getting the binaries of gcc from the official or trusted source is preferred.


Why Cross Compiling

Cross compiler enables us to compile ARM code on x64/x86 machines with 10 times plus speed. we will use it for Kernel, U-Boot, and other compilation.

To understand what a cross compiler is, plz read http://en.wikipedia.org/wiki/Cross_compiler

actual install

cd /opt
sudo wget http://releases.linaro.org/14.04/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz
