What about using libdir as configure intends, which is (IMO), where
you put the symlink targets in the default case? Remember that some
users might go further and specify
./configure --libdir=...
and be rather confused when your Makefiles don't honor that. You can
use something different (i.e., not 'libdir') for the true locations of
the libraries in their version-specific directories.
In fact, I think that autoconf gives you something like
pkglibdir = $(libdir)/lesstif
pkgincludedir = $(includedir)/lesstif
that you might use for this purpose. Something like
$(pkglibdir)/Motif2.0/libXm.so.2
would be safer than the current
$(prefix)/lib/LessTif/Motif2.0/libXm.so.2
for example. When I say "safer", I mean more likely to be consistent
with user-specified configure options.
If pkglibdir is too radical a change, then your suggestion to use
$(exec_prefix)/lib/LessTif/Motif2.0/... would probably suffice. (But
my point remains that this should not be called 'libdir'.)
Hope this helps. I would be delighted if this were taken to heart. I
am willing to offer patches, but it might be a week or too before I
could prepare something for you.
Kind regards,
David
