[Coin-discuss] Building CBC with MathProg support?

[John J Forrest]

Sebastian,

gmpl interface does work with standalone cbc.  I tried cbc
cbc-bug-mathprog.mod% and it worked OK.

Sebastian,

Not tested for some time but syntax was model file followed by % followed
by optional data file.  When I tried just now it gave syntax error in data
section.  Called as cbc cbc-bug.mod%

So it gets into gmpl.

If I have time I may be able to look at it.

Hello Stefan,

thanks for the hint.  It now compiles with GLPK support.  However, I do
not know how to read and solve a MathProg model using cbc.  The import
function only reads MPS files.

How to make CBC read in a .mod file?

Thanks,
Sebastian
