Sorry, I hit the send button before the writing was complete:
I'd like to use the optimization library donlp2 with maxima. Has anyone
succeeded in doing this?
I tried to use f2cl on the fortran code, but f2cl doesn't handle include
files. So I pasted them into one big file but now I get an
Error: 0 is not a character designator.
Alternatvely, it may be an idea to use cffi together with the C version
of donlp. But this seem sto be tricky as the function evaluation from
the C code requires callbacks to Lisp.
Any suggestions?
I'm not completely bound to use donlp but I need fast constrained
optimization.
