[SCIP] Error when optimizing TEST0055

[Mohamed Mustapha Kabbaj]

Hi every one,

I've problem with the optimization of a test example in gcg.
Even if I've followed step by step the installation page in the
documentation in the official website, i got the following errors when
typing the command *optimize *in the gcg command line interface.

I've tried with other instances, but I still had errors.

Could anyone tell the solution please.


Cordially,
