I have a fully working problem on a Windows machine using V12.2.

I transfer it to a linux machine using V12.3.

I see this error:

Error using cplexlink123
CPLEX Error  1219: No names exist.
 
 
Error in /home/ed/ILOG/V12.3/cplex/matlab/@Cplex/Cplex.p>Cplex.solve (line 1474)

Error in miptest (line 38)
cplex.solve();

This is my code:

cplex = Cplex('mymodel');
cplex.readModel('mymodel.lp');
cplex.Model.sense = 'maximize';
cplex.Model.ctype = ['C' * size(cplex.Model.A(1,:),2)];
cplex.Param.preprocessing.presolve.Cur = 0;
temp = find(cplex.Model.lhs ~= -Inf);
cplex.Model.A = [cplex.Model.A; cplex.Model.A(temp,:) * (-1)];
cplex.Model.rhs = [cplex.Model.rhs; cplex.Model.lhs(temp) * -1];
cplex.Model.lhs = [cplex.Model.lhs; -Inf * ones(size(temp,1),1)];
cplex.Model.lhs(temp) = -Inf;
cplex.solve();

Any idea what is going on?

Windows to Linux isn't the issue. Installed v12.2 for linux and works fine. Exact same code on all instances. Not sure what is going on. It's working, though, so I'm fine.

Could you please attach mymodel.lp file, then I can take it to reproduce?
