There is an article called "recursive make considered harmful". According to it, you should have just one Makefile.am in top level with all the rules (all libs etc). By this, make can show its strengths best. Often, a Makefile.am "per directory" seems to be used, but for a new project today this should be avoided. It just slows things down and leads to unneeded compiler calls. I'm sorry, but where on earth did you get this terrible information? A Makefile.am per directory is precisly what should be used, it doesn't incure any extra compiler calls. It also makes it easy to build seperate parts of the tree. [...] Instead of HAVE_SDL better would be if ENABLE_MYLIBSDL I think. Please don't. `Enable' means to enable a feature, linking to a library is not a feature. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
