Hi, I am trying to build Open MPI 1.4.3 with thread support on Windows. A trivial test program runs if it calls MPI_Init or MP_Init_thread(int *argc, char ***argv, int required, int *provide) with reguired=0 but hangs if required>0. ompi_info for my build reports that there is no thread support but MPI_Init_thread returns provide==required.
The only change in the CMake configuration was to check OMPI_ENABLE_MPI_THREADS. Is there anything else that needs to be done with the configuration? I have built 1.4.3 with thread support on several linuxes and mac and it works fine there. Regards, Bjorn Regnstrom
