[pacman-dev] Possible start to a new make system

18 Jan 2007

      My little project for the night, and I wanted to get better with
makefiles anyway. I basically copied the code directory, removed
anything that started with Make or ended in .am, and dumped all the
configure stuff. I used your suggestion yesterday of looking at the
wmii Makefile, Aaron, and it is pretty similar. The biggest issues
were the fact that we are building libraries, and we are working out
of multiple subdirectories.

Current status of this will hopefully build libalpm and pacman
successfully. I haven't done anything for the scripts, etc, yet, but
that shouldn't be hard to add. The biggest point of this was just to
see if it could be done.

There are currently three files involved in the build process now, all
in the root of the project: Makefile, config.mk, and config.h. I
didn't want to destroy the code by removing config.h, so I pretty much
just ran a configure, kept config.h, and put it in the directory.

Let me know what you guys think. 3 files inlined here. Obviously still
a lot of work to do, but this is my start.
