If you honestly tried to put all the xserver build in a single Makefile, you'd want to stab yourself shortly after. One of the real advantages of recursive make is that skipping parts of the build is really easy. You just put the subdir under an AM_CONDITIONAL and you're done. The actual Makefiles in the subdirectory can stay clean because they're being skipped completely. If you wanted to put that all in a single unit, you'd end up with an insane maze of AM_CONDITIONALs that no one could understand. You know how it's nice when you get rid of #ifdefs in code? This is the opposite of that process. -- Dan _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
