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

[Guillaume Letellier]

Hello, and thank you for your answer.

You're right, i missed the fact that error code was hex and not decimal, the 
hex error code is 0x0C (12d). Should be "GLP_EROOT" if i'm right ...

Glp_intopt cannot return GLP_EDATA. Print the code returned by glp_intopt
in hex and then find it in glpk.h.
