The following adjusts libgm2 to properly use the multilib build infrastructure, thereby fixing the install with --enable-version-specific-runtime-libs In particular config-ml.pl needs to be applied to generated Makefiles as documented in the manual and we have to avoid clobbering the variables via make arguments. The explicit install rules used different ways to construct the multilib dir which isn't necessary and breaks when MUTLIDIR is now finally set correctly. Instead use $(toolexeclibdir). This results in some dead variables in the Makefile.am (and there were some before), I refrained from doing even more changes here. Verified with an install with and without --enable-version-specific-runtime-libs and checking the result. PR modula2/108144 libgm2/ * configure.ac: Apply config-ml.pl to the generated Makefiles. Set multilib_arg, use AM_PROG_LIBTOOL. * configure: Regenerate. * Makefile.am (AM_MAKEFLAGS): Do not override MULTI* flags. * Makefile.in: Regenerate. * libm2cor/Makefile.am: Install to $(toolexeclibdir)$(M2LIBDIR) rather than $(inst_libdir)/$(MULTIDIR)$(M2LIBDIR). * libm2iso/Makefile.am: Likewise. * libm2log/Makefile.am: Likewise. * libm2min/Makefile.am: Likewise. * libm2pim/Makefile.am: Likewise. * libm2cor/Makefile.in: Regenerate. * libm2iso/Makefile.in: Likewise. * libm2log/Makefile.in: Likewise. * libm2min/Makefile.in: Likewise. * libm2pim/Makefile.in: Likewise.
