I'm searching for a solver unit for linear equations. This should run under GPC/MinGW.
Is there something available?
I do not know about any such unit. However, I think that correct solution is to create bindings to Lapack and BLAS (more precisely Atlas). Lapack + Altas give proven high-performance collection of matrix routines and IMHO it make no sense to reinvent the wheel (well GSL folks appearently chose to rewrite ...). Lapack is in Fortran 77 and Atlas is in C (but with Fortran 77 bindings). Lapack + Altas contain together about 1200 routines, so it is substantial work involved if you want easy access to all of them. But for any single one the work rather strightforward. I called equation solver from C on Linux, but also created (by cross compilation) a Mingw binary (a static library).
