Hello Julian !

I'm not sure what you mean by "Glpsol cannot read MPS files with an OBJSENSE section".

The changes I've made on my fork to allow it to work does read/write OBJSENSE from freemps .

Can you provide an example ?

Cheers !

Although Glpsol will now write out MPS files for maximization problems properly using the OBJSENSE section, Glpsol cannot read MPS files with an OBJSENSE section.

Since MPS files generated outside Glpsol may have an OBJSENSE section, this is important to fix
