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


Installation

Linaro gcc at launchpad.net:

Toolchain Home Page: https://launchpad.net/linaro-toolchain-binaries/

prerequisites ubuntu 14.04

sudo apt-get -y install bc build-essential device-tree-compiler lsb-release lzma lzop fakeroot ccache libc6-i386 libstdc++6:i386



prerequisites ubuntu ubuntu 16.04

sudo apt-get -y install bc build-essential device-tree-compiler lsb-release lzma lzop fakeroot ccache libc6-i386 libstdc++6:i386 u-boot-tools  module-init-tools

if there is a problem with: kernel/timeconst.pl, please change line 373:

if (!defined(@val)) {

armhf toolchian install (both 14.04 and 16.04)

cd /opt
sudo wget https://launchpad.net/linaro-toolchain-binaries/trunk/2013.10/+download/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux.tar.xz
sudo tar -xvf gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux.tar.xz
echo "PATH=/opt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin:${PATH}" >> ~/.bashrc


On old ubuntu system (with apt install)

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

test installation

re-login your console and test with:

root@avernus:~# arm-linux-gnueabihf-gcc
arm-linux-gnueabihf-gcc: fatal error: no input files
compilation terminated.

yeh! it works!


for ubuntu 12.04
