This is getting more and more hopeful all the time. I started diving into the gnulib/havelib stuff and have made good progress, but I'm curious...If I wanted to use libtool, how would I do it? Put AC_PROG_LIBTOOL in configure.ac, and then what? Sorry to be dense, but all the info about lib_LTLIBRARIES, etc. doesn't seem to apply. Here's where I've gotten with gnulib/havelib in case this is helpful for others. I also have some questions at the end. Following the instructions at http://www.gnu.org/software/gnulib/manual/gnulib.html#Invoking-gnulib_002dto ol, I tried: -bash-2.05b$ ~/archive/gnulib/gnulib/gnulib-tool --dry-run --import havelib Module list with included dependencies: havelib File list: build-aux/config.rpath lib/dummy.c m4/gnulib-common.m4 m4/lib-ld.m4 m4/lib-link.m4 m4/lib-prefix.m4 (and some recommendations to use gl_* macros in my configure.ac) Some of this looks like overkill so I just copied the m4/lib-*.m4 into my project's m4 directory (I already have some of my own macros there). I also made a build-aux directory in my project and copied config.rpath there. >From there: - add AC_CONFIG_AUX_DIR(build-aux) to my configure.ac - remove config.guess, config.sub, depcomp, install-sh, missing since autoreconf now puts them in build-aux - add AC_LIB_LINKFLAGS([xerces-c]) since that's the library I'm concerned with at the moment - run autoreconf -fvi - run configure --with-libxerces-c-prefix=/my/path/to/xerces-c - Observe the exciting contents of LIBXERCES_C, LIBXERCES_C_PREFIX, and LTLIBXERCES_C in my generated Makefiles. - Also observe that CPPFLAGS now includes -I/my/path/to/xerces-c/include My reflex is that I don't want CPPFLAGS to include the xerces-c path...that I would prefer AC_LIB_LINKFLAGS just AC_SUBST([INC]NAME) instead of AC_LIB_APPENDTOVAR([CPPFLAGS], [$INC]NAME). I can modify the macro to do that but I'm curious what other people's take is on this issue. I figure I'll only use the xerces include path when I need it. I'm pretty sure I just add LIBXERCES_C to the relevant *_LDADD variables in my Makefile.am's. LIBXERCES_C_PREFIX seems straightforward. I'm less sure about LTLIBXERCES_C, but I suppose that's because I'm not using libtool. It's OK to ignore it until then, yes? Thanks again. -DB _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
