[Help-glpk] milp optimisation suceed with glpsol but fails with API

[Guillaume Letellier]

Dear all,

I'm facing a strange issue using GLPK : I set up a milp problem using
the API in C#. Solving the problem in memory using intopt fails with
error code GLP_EDATA.
Yet, if I write the problem to MPS using glp_write_mps (file attached),
i can found the solution with glpsol.exe

Any idea of what I must have missed ?

Thank you for your help, 

Regards
