Hi again all,

Hopefully, this time my reply will also appear on the help-glpk
archive as I subscribed there.

As far as Marco's patch is concerned, it is fine and work, but passing
-no-undefined directly through LDFLAGS is not the right way to go.
The -no-undefined flag is really meant for libtool, not for the linker.
In fact the proper way to go would be to put it into
something_la_LTFLAGS but this does not work...
So the most usual solution is to put it into library_la_LDFLAGS (which
is a variation of LDFLAGS but meant for libtool).

Sorry Jean-Pierre,
but you are mistaken:

global LDFLAGS are passed to libtool, as seen in this extract
of the "src/Makefile" in the build tree.

libglpk_la_LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) \
        $(LIBTOOLFLAGS) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) \
        $(libglpk_la_LDFLAGS) $(LDFLAGS) -o $@
