Hi Alberto, >From your log for the successful run, it seems like you have multiple instances of Dyninst installed: one in /home/aolmo/soft/dyninst-9.3.2/install/lib/ and the other one in /usr/local/lib/. Do you know whether these two instances of Dyninst are the same version? I would recommend that you ensure that you compile your application and run your application with the exact same installation of Dyninst.
I am not sure whether this is the cause, but it is indeed strange that one application can find DyninstRT, but the other one cannot find it.
