I could not help notice the name of your file was "make_sparse".
I've been working on some ways to implement sparse matrix manipulations
at the ".m" level (I have been using mostly octave primitives and just
one hand-hacked .oct file for a kind reduction octave doesn't yet support).
Could you and I exchange information, and perhaps, if others are interested,
have a general discussion about sparse matrices in octave?

I suggest that the -c option be added to mkoctfile.
This would have the same effect as with gcc, ie
to compile to object but not link:

So, for example, you could do
An:~/octave/sparse> mkoctfile -c make_sparse.cc -ISuperLU/SRC/
An:~/octave/sparse> mkoctfile make_sparse.o -lsuperlu -L.

This would allow it to be nicely used in Makefiles,
so that large projects with multiple source
files don't need to be recompiled from scratch
each time.
