Crosstool-ng is commonly used to build a cross-compiler toolchain in various Linux distributions. In Gentoo, the cross-compiler environment generator, crossdev, has been made for our convinience. It is a set of bash scripts that utilize emerge to provide a system integrated cross-compilation capability.

In this article, we are going to walk through building cross-compiler toolchain for an operating system and the embedded target (bare matel).

Emerge to install crossdev.

$ sudo emerge --ask sys-devel/crossdev
