Thanks a lot! It looks promising, indeed. One small problem with this is that it requires -I$(top_builddir) in CPPFLAGS since it wants to include LT_CONFIG_H=relative/path/config.h Not sure how this could be improved. Maybe by passing the absolute path in LT_CONFIG_H? Or by allowing to manually override it? Brice _______________________________________________ https://lists.gnu.org/mailman/listinfo/libtool
