Hi, I am getting a compile error on my pc.

[ 76%] Performing build step for 'MPI_PLUGIN_pkg'
[ 50%] Linking CXX shared module libpdi_mpi_plugin.so

This occured after a distrib upgrade, and my compiler also got upgraded at some point from 9.3.0 gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0 MPICH Version: 3.4.1

3:19 julien's take is that it's trying to link against the .a lib while the .so is also available...

It compiles on the compilation farm, is it still an issue on your side? What's your OS, environment, etc?

Ok the failure was probably due to corrupt dependencies. It appeared after an OS upgrade, accompanied with a compiler update. Cleaning the environment and reinstalling mpich solved the problem.
