Compiling core on heisenbug about pumgen

[krenzland]

You set:
export mpi_name=mpich3
But it uses:
/opt/software/openmpi/buster/4.1.0_gcc-10.2.0/include/openmpi/ompi/mpi/cxx/op_inln.h:123:38: error: cast between incompatible function types from ‘void (*)(const void*, void*, int, const MPI::Datatype&)’ to ‘void (*)(void*, void*, int*, ompi_datatype_t**)’ [-Werror=cast-function-type]

mpi_name should be openmpi3 (I assume it's openmpi3!)

Thx, true but this does not solve the problem:

You can try to deactivate -Werror. Not sure why anyone would enable this by default, this is definitely not good practice.
You can remove it here:
https://github.com/SCOREC/core/blob/c528f981f873fbf54575c225989bd7ff060f12c9/cmake/bob.cmake#L67
and line 71.

Ok this indeed fixed my problem. Thx!
