Problem facing while running Madgraph in cluster

-lstdc++ is the standard C++ library.
This should be provided by you/your system.
It is not unusual for cluster to be configure such that you can not compile code on the cluster.
In any case, I should advise you to check the manual of your cluster and if you do not find the information there, you should contact your sys admin.

Cheers,

Olivier
