[cffi-devel] Linking CL to fortran-77 via cffi

[Mirko Vukovic]

Liam,

I think Tamas Papp is much ahead of me in terms of linking cl to f77 arrays
(especially on SBCL).  Your best bet might be to somehow link to his LLA
package (https://github.com/tpapp/lla).  I suspect that his package also
grovels through the f77 libraries, automatically generating CL defun's.
But once I could not find what I was looking for, I stopped digging.

My work originates from the need to link to one or two subroutines for
special functions that were note available via gsl (and gsll/antik).

Ideally, there would be a suite of four (or fewer) packages that provide
- examples of linking (as the current package does)
- automatic defun generation (something like defun-fortran-call ...)
- groveller
- interfaces to particular libraries (lapack, netlib, toms)
Ideally those would be four packages, so that the user can choose which one
suits him best.

It might be best to discuss with Tamas, and with his guidance extracts
parts of LLA into separate packages, that he can then also use in LLA.
