Preparing Build Environment

Fedora 26 or Ubuntu 16.04 is recommended.

Fedora 26

$ sudo dnf -y install gcc-c++ perl-Thread-Queue qemu-system-arm

Ubuntu 16.04

$ sudo apt install gcc g++ wget git qemu-system

Get CLFS-ARM Source code

git clone --depth 1 https://github.com/LeeKyuHyuk/clfs-arm.git

Build CLFS-ARM

Use make list-defconfigs to display the list of boards, and load with make <name>_defconfig command.

make <name>_defconfig

Download the source code by doing make download.

make download
make all

Build Toolchain

make toolchain

$ arm-linux-gnueabihf-gcc --version
