With a big help from the community, I've fixed my problem. I had to include the extra-libraries when building the hcholmod library. I'll push a new version later today.

Hi,

I'm trying to create an FFI library to CHOLMOD (http://www.cise.ufl.edu/research/sparse/cholmod/) but am having problems.

My project is here: github.com/tdox/hcholmod. I can link an executable with the build script in the examples directory (line 4). But line 7 does not work (I get undefineds for functions that are in cholmod.a. Also, I can't build example1 with cabal. (Uncommenting the -- lines in hcholmod.cabal results is similar undefineds.)

I would appreciate any help or hints.

Thanks,

Tad
