Actually her Makefile.am contains C++ sources: ! vtv_init_sources = \ ! vtv_init.cc ! ! vtv_stubs_sources = \ ! vtv_stubs.cc which should be enough to make it use CXXLINK, but her Makefile.in contains: + libvtv_init_la_LIBADD = + libvtv_init_la_SOURCES = vtv_init.c + libvtv_init_la_OBJECTS = vtv_init.lo + libvtv_stubs_la_LIBADD = + libvtv_stubs_la_SOURCES = vtv_stubs.c + libvtv_stubs_la_OBJECTS = vtv_stubs.lo ... ! SOURCES = $(libsupc___la_SOURCES) $(libsupc__convenience_la_SOURCES) \ ! libvtv_init.c libvtv_stubs.c ... but then still ... ! vtv_init_sources = \ ! vtv_init.cc ! ! vtv_stubs_sources = \ ! vtv_stubs.cc So, the first hunk of Makefile.in contains references to .c files. Caroline: did you edit Makefile.in yourself? Otherwise I don't see how this file could have been generated by automake with this inconsistent use of .c/.cc. Or maybe you have still .c sources lying around in your source tree? Ciao, Michael.
