[SCIP] Using barrier solver when linked to Gurobi?

[Franzen, Christian]

I have compiled SCIP 7.0.0 against Gurobi 9.0.0 and I am trying to use Barrier method WITHOUT crossover for solving my node relaxations. However, I always receive the following error:


1/1 feasible solution given by solution candidate storage, new primal bound 2.919805e+10

WARNING: LP solution value is above SCIP's infinity value
feasible solution found by completesol heuristic after 1.0 seconds, objective value 2.657620e+09
presolving:

WARNING: LP solution value is above SCIP's infinity value
(node 1) unresolved numerical troubles in LP 0 -- using pseudo solution instead (loop 1)
(node 1) forcing the solution of an LP (last LP 0)...

[solve.c:4989] ERROR: Error <-6> in function call
[scip_solve.c:2653] ERROR: Error <-6> in function call

Any idea what is going on there? Dual simplex, primal simplex and barrier WITH crossover ist working just fine. It seems to be not related to my LP files, I have tested at least 5 of them, all with the same error.
