PS: what do you mean with the environment variable in this scenario?

By making the MPI library load all tools before initialization completes, the ordering of library constructors is no longer important and we can be sure, that all tools can register themselves in time. I played a bit around: https://github.com/jprotze/toolload The tool is dynamically linked into the application, but the constructor would be called after the test library initializes the api. In this case, the env variable ensures that the tool can register in time. Best Joachim -- Dipl.-Inf.
