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)) {
to
if (!@val) {
https://freetz.org/ticket/2759
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!
gcc 5
Later kernel requires later version of gcc. please download Linaro gcc binaries:
wget http://releases.linaro.org/components/toolchain/binaries/5.4-2017.01/arm-linux-gnueabihf/gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf.tar.xz
