Why do I see compiler errors of process models while migrating to 12.0 from previous versions ? I can see errors likeC:/op_models\op_models\global_srw_mac.pr.cpp(102) : error C2065: 'op_sv_ptr' : undeclared identifierC:/op_models\op_models\global_srw_mac.pr.cpp(102) : error C2227: left of '->channels' must point to class/struct/union
