Building libFIRM from the public repository

libFIRM is yet another IR(intermediate representation) from University of Karlsruhe. It has been public for the last year, but the repository was not. Recently, the repository has been published at github, which is a good news.

On the other hand, there doesn't seem to be any documentation for building from the repository. Since the build process is not exactly straightforward, here is a little recipe.

First you want to clone the repository:

$ git clone git://github.com/MatzeB/libfirm
$ cd libfirm

Then you need to generate some source files from scripts.

$ python scripts/gen_ir.py spec ir/ir
$ python scripts/gen_ir_io.py spec ir/ir

The rest is standard autotools build, except there is no autogen.sh.

$ libtoolize
$ aclocal
$ autoheader
$ autoconf
$ automake --add-missing

Now configure and make.
