Hi,
I am working with a library (CGAL) that is not autoconfigured, but has
its own system that generates a makefile fragment with important make
variables defined. In particular, it defines CGAL_LDFLAGS.
In my Makefile.am, I use
include $(CGAL_MAKEFILE)
...
LDADD = ... $(CGAL_LDFLAGS) ...
and automake complains:
Makefile.am: invalid unused variable name: `CGAL_LDFLAGS'
[Incidentally, there used to be a line number attached to this diagnostic,
but that suddenly stopped. (??)]
Since automake does generate the correct output Makefile.in, I can
live with seeing this message all the time. However, I am concerned
that this "warning" may change to an error in the future, and my
builds will suddenly break. Thus I wonder: what is the automake-blessed
way to deal with including makefile fragments that define variables
that automake considers its own?
I used to be able to suppress this behaviour by a dummy assign to
CGAL_LDFLAGS (before including CGAL_MAKEFILE, of course!). But that
trick has stopped working.
Thanks,
-Steve
