Problem MPI_CXX during default Compilation

Asked by Steve Underwood

Hello,

I wanted to do the default Compilation, however cmake couldn't find MPI_CXX. That is the Output from the Terminal:

 Could NOT find MPI_CXX (missing: MPI_CXX_WORKS)
CMake Error at /home/zszlobod/cmake-3.19.7/Modules/FindPackageHandleStandardArgs.cmake:218 (message):
  Could NOT find MPI (missing: MPI_CXX_FOUND) (found version "3.1")

      Reason given by package: MPI component 'Fortran' was requested, but language Fortran is not enabled.

Call Stack (most recent call first):
  /home/zszlobod/cmake-3.19.7/Modules/FindPackageHandleStandardArgs.cmake:582 (_FPHSA_FAILURE_MESSAGE)
  /home/zszlobod/cmake-3.19.7/Modules/FindMPI.cmake:1722 (find_package_handle_standard_args)
  CMakeLists.txt:590 (FIND_PACKAGE)

When I looked up CMakeError.log , it says test_mpi for CXX in mode normal failed to compile:

The MPI test test_mpi for CXX in mode normal failed to compile with the following output:

I tried to reinstall openmpi and cmake, but that didn't work. Can anyone help me?
Compiler: gcc 7.5.0
cmake 3.19.7
openmpi 2.1.1
yade 2020.01a
Ubuntu 18.04.4 lts

Thank you in advance!
Steve

Hi,

Are you using "gold" linker? [1]
If so, this is a known cmake issue (independent of yade, with still no idea how to fix) and I would suggest to disable either ld.gold or disable MPI option.

No i use ld-linker. I would like to enable the MPI option to use Yade with Openfoam. Is there another way to enable MPI without facing problems with cmake?

It looks like you are using clang, which has problems with MPI. Please use gcc instead.

oh thank you this worked! I actually set the compiler to gcc but test_mpi somehow compiled with clang? I solved it by deleting clang to compile yade.
