Roberto,

has anyone any experience of using libtool with plld? To be more specific, I am using libtool to build a library for which I wrote a SWI-Prolog interface. I am now using an automake rule like

ppl_pl$(EXEEXT): ppl_swiprolog.o ppl_pl.o plld -pl-options,-g,main., -o $@ $+ -L$(top_builddir)/src/.libs -lppl

but this has the drawback implied by directly referring to the contents of the .libs directory. What I would like to say is something like

ppl_pl$(EXEEXT): ppl_swiprolog.o ppl_pl.o libtool --mode=link plld -pl-options,-g,main., -o $@ $+ $(top_builddir)/src/libppl.la

so that the right thing happens before and after `make install', but this fails horribly. Any idea how I could achieve that effect, yet retaining the hope that things will continue to work also in future releases of SWI-Prolog? Thanks a lot

Actually, libtool and plld for a large part are doing the same thing: provide cross-platform support for linking, notably involving shared-objects/DLLs. In addition, plld provides support for generation mixed Prolog/C executables. I think the correct way is to add libtool compatibility options to plld so it can provide the mixed Prolog/C linking, while using the normal libtool facilities for creating the executable without the Prolog part.

My knowledge of libtool is very limited. I'm more than happy to include this type of support on your directions though.
