Tamas,
Here's what I have in GSLL
(case (cffi:foreign-type-size :long) (8 (push :int64 *features*) #+fsbv (fsbv:defsynonym sizet :uint64)) (4 (push :int32 *features*) #+fsbv (fsbv:defsynonym sizet :uint32)))

Hi,
Is there a way to detect the size of integers (ie 32 or 64 bit) used by a library?
I am using LAPACK/BLAS (ATLAS) libraries via CFFI. Recently, my tests failed, and to my surprise, the solution was to use 32-bit ints. Note that I am on a 64-bit platform, using the Ubuntu libraries, so why this happens is a mystery. But it would be great if I could detect it somehow from within Lisp.
Thanks,
Tamas
