Building llvm-gcc 4 from Source

This section describes how to aquire and build llvm-gcc4, which is based on the GCC 4.0.1 front-end. This front-end supports C, C++, Objective-C, and Objective-C++. Note that the instructions for building this front-end are completely different (and much easier!) than those for building llvm-gcc3 in the past.

  1. Retrieve the appropriate llvm-gcc4-x.y.source.tar.gz archive from the llvm web site.

    It is also possible to download the sources of the llvm-gcc4 front end from a read-only mirror using subversion. To check out the code the first time use:

    svn co dst-directory

    After that, the code can be be updated in the destination directory using:

    svn update

    The mirror is brought up to date every evening.

  2. Follow the directions in the top-level README.LLVM file for up-to-date instructions on how to build llvm-gcc4.
