I am facing an error while compiling OpenFOAM-dev from sources in my Ubuntu 14:04 machine while following the instructions on OpenFOAMwiki page. I am installing it with "Debug" option and GCC compilers. I am stuck in step 12.2 and the system info & error message is as follows:
Sys info: Code:

Quick answer: The output indicates that you are not using the default Open-MPI system installation, given that it's using the file "/usr/local/include/mpi.h".
Which specific MPI version are you using? It doesn't seem to be compatible or perhaps you need to adjust the OpenFOAM environment variable "WM_MPLIB" to the correct setting. For getting the specific version of Open-MPI that you are using, try running this command: Code:
mpirun --version which mpirun
