Not sure if this is more automake or autoconf related. I'm fairly early in the process of creating one top level Makefile.am/configure.ac to get non-recursive Makefiles. I've got a few directories already building with autoconf/automake. I'm using AC_CONFIG_SUBDIRS at the moment so configure still runs for each subdirectory.
They all use m4 macros that they get access to with: ACLOCAL_AMFLAGS = -I <macro directory path> I added the same to my top level Makefile.am, although the path is different... This happens to work, but I get warnings from autoreconf: util/libutils/src/Makefile.am:6: ACLOCAL_AMFLAGS multiply defined in condition TRUE ... Makefile.am:14: `util/libutils/src/Makefile.am' included from here Makefile.am:7: ... `ACLOCAL_AMFLAGS' previously defined here If I remove the "second" assignment to ACLOCAL_AMFLAGS from the sub-Makefile.am, the warning goes away, but configure fails in the subdirectory since macros it needs aren't available. I guess aclocal only copies macros that it needs to, but I use many more macros in the subdirectories that aren't getting into aclocal.m4. Do I need to switch things to only run configure once at the top? My reflex is to avoid that at least for now. Anyone have any suggestions for getting this to work without warnings? -bash-2.05b$ automake --version automake (GNU automake) 1.9.6 -bash-2.05b$ aclocal --version aclocal (GNU automake) 1.9.6 -bash-2.05b$ autoconf --version autoconf (GNU Autoconf) 2.59 Thanks much. -DB
