Let's say you build a package that needs libthis and libthat. Is the idea that after configure is run, LIBS="-lthis -lthat", and you use @LIBS@ in the Makefile.am, or rather that after configure is run THIS_LIBS=-lthis, THAT_LIBS=-lthat, and Makefile.am has LIBS=@THIS_LIBS@ @THAT_LIBS@ ? Also, what do you do about finding out whether the system needs -rpath or not? libtool must know, but how can it tell me? .. oh, and, what do you do about aclocal -I mym4dir? The automake doco mentions setting ACLOCAL_AMFLAGS = -I mym4dir, but how does that tie in with AC_CONFIG_MACRO_DIR(mym4dir)? Cheers, Patrick
