SQLSTATE Error not showing up in mclient Aug2018 version (Aug2018 (11.31.7))

All, Do we have a way to compile mclient along with server source code? We are not able to see SQLSTATE error code on concurrency with Aug2018 (11.31.7) server version along with mclient Aug2018. Would like to see if we need to specifically compile client too? ERROR = !COMMIT: transaction is aborted because of concurrency conflicts, will ROLLBACK instead CODE: 40000 Regards, Sreejith
