This document describes the generic installation procedure for GCC as well as detailing some target specific installation instructions.
GCC includes several components that previously were separate distributions with their own installation instructions. This document supersedes all package specific installation instructions. We provide the component specific installation information in the source distribution for historical reference purposes only.
Before starting the build/install procedure please check the host/target specific installation notes. We recommend you browse the entire generic installation instructions before you proceed.
The installation procedure itself is broken into five steps.
Please note that GCC does not support `make uninstall`
and probably won't do so in the near future as this would open a can
of worms. Instead, we suggest that you install GCC into a directory of
its own and simply remove that directory when you do not need that
specific version of GCC any longer.
