mpi.h not found Installing openCARP in supercomputer

Question

Dear openCARP community,

I am trying to install openCARP on a supercomputer, I have followed the tips given here and also on the openCARP installation website. I believe I have all the modules needed:

module purge
module load numlib/petsc/3.13.4-gnu-10.2-openmpi-4.0
module load numlib/python_scipy/1.5.2_numpy_1.19.1_python_3.8.6_gnu_10.2
module load devel/cmake/3.18
module load compiler/gnu/8.3.1
module load mpi/openmpi/4.0

However the compilation terminates at 13% with a fatal error:

[ 13%] Building CXX object numerics/CMakeFiles/numerics.dir/basics.cc.o
In file included from /home/kit/ibt/yw3537/openCARP2022/numerics/basics.cc:27:

 #include <mpi.h>
          ^~~~~~~
compilation terminated.
gmake[2]: *** [numerics/CMakeFiles/numerics.dir/build.make:82: numerics/CMakeFiles/numerics.dir/basics.cc.o] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:488: numerics/CMakeFiles/numerics.dir/all] Error 2
gmake: *** [Makefile:171: all] Error 2

Any ideas on how I could fix this error? Many thanks.

I have tried to compile openCARP on the BWUniCluster and got the same result.

The problem is that the cmake does not find the MPI libraries at the configuration. When I change the `find_package(MPI)` to `find_package(MPI REQUIRED)` in the `CMakeLists.txt:24` than it fails already at the configuration.

Then I have tried to add `PATHS` to the `find_package` and `APPEND` to the list `CMAKE_MODULE_PATH` with the environmental variable `$MPIDIR` (which is `/opt/bwhpc/common/mpi/openmpi/4.0.5-gnu-10.2`) and its subdirectories, but without a success.

Answer 1

Which include directories are given to the compiler? You should be able to see this either by looking in the CMakeCache.txt file(s) or by running ccmake instead of cmake

I look at the CMakeCache.txt and I found this:     include_directories(${LLVM_INCLUDE_DIRS})
    include_directories(${MLIR_INCLUDE_DIRS}), but they are not defined in the file itself. I purged the modules and load them again and now the problem with mpi is fixed:

Currently Loaded Modules:

1) mpi/openmpi/4.0                                                        
2) numlib/petsc/3.13.4-gnu-10.2-openmpi-4.0
3) compiler/gnu/10.2
4) devel/python/3.8.6_gnu_10.2
5) numlib/python_numpy/1.19.1_python_3.8.6_gnu_10.2
6) numlib/python_scipy/1.5.2_numpy_1.19.1_python_3.8.6_gnu_10.2
7) devel/cmake/3.18  

Now I have another error with a module:

/opt/bwhpc/common/mpi/openmpi/4.0.5-gnu-10.2/lib64/libfabric.so.1: undefined reference to `rdma_establish@RDMACM_1.0'
