Look at GraphicsMagick for example. ;-) Look at http://www-src.lip6.fr/homepages/Alexandre.Duret-Lutz/autotools.html > My problem is that my project contains one big library which is built of many > source files spread over different sub-directories.

But unless there's compelling reasons, I wouldn't do it. Some people prefer during development it because it does not rebuild so much (exactly because the recursive make does not have all dependency information available). Cheers, Ralf
