Quadratic programming solver for Gnumeric

• OOQP - homepage This solver proved to be usable, but it needs libblas, fortran library and it's written in C++, so it also needs libstdc++ in order to compile. Another problem: the source is pretty complicated, so i find it hard to include it in form of a source code, i just used .a libraries. I included it in Makefile.am files but not in configure. I still lack some know-how to do this. Maybe if someone creates ooqp as a package for linux, it will be much easier.
• COPL_QP - homepage COPL_QP has no dependencies, but it wasn't able to solve all the problems. When the variables aren't bounded, it usually states that the problem is infeasible. There are some parametres of the algorithm which can be set easily, but i don't know yet how to set them in order to get the best results I already tried to ask one of the authors and i'm waiting for the reply.
• QLD - also independent of any libraries, but the license is currently owned by prof. Klaus Schittkowski. But maybe I could obtain the old Fortran version in some other way and use it. I'll give it a try.
