These scripts create a cross-compiler toolchain in your $HOME/usr directory. This kind of cross-compiler is mostly useful for basic Operating System developpment.

Included packages

These scripts install the following things in the toolchain :

  • binutils (ld, ...)
  • gcc for C and C++

Supported cross-compiling architectures

  • x86 : use i586-elf prefix
  • arm (not maintained) : use arm-elf prefix

The scripts for both architecture are very similar, feel free to adapt them to other architectures.

Setting up the cross-compiler

  • Create a directory named usr in your home directory.
  • Add the following line to your .bashrc : export PATH=$PATH:$HOME/usr/bin
  • Run cross-<arch>.sh for the architecture you target. Go on the internet and read some useless stuff, this step is long.

The compiler is available as *-gcc and *-g++, where * is one of the prefixes listed above (ex: i586-elf-gcc).
