Hi,
While working on a CMakeLists.txt for GLPK 5.0, which I mentioned in the help-glpk mailing list, I noticed that the glpk_5_0.def file in the ./w32 and ./w64 directories lists glp_netgen_prob as a function to export.
I think glp_netgen_prob should be removed from .def file for the following reasons:
1. No glp_netgen_prob definition exists in the GLPK 5.0 source
2. Makefile_VC_DLL recipes in ./w32 and ./w64 fail with linker error (glp_netgen_prob is unresolved external symbol)
By simply removing glp_netgen_prob from the .def file the Makefile_VC_DLL recipe succeeds. Otherwise, there should be some implementation that asserts for glp_netgen_prob (like glp_netgen) so there is at least a definition for the linker.
Best,
Derek
