undefined symbol: mpi_fortran_in_place_

[harry900831]

Hi,
When I follow the instruction of README.md to execute the MPI program, the following error has shown up:

/usr/bin/bash: symbol lookup error: /path/to/src/alltoallv/liballtoallv.so: undefined symbol: mpi_fortran_in_place_

It seems that in the source code, mpi_fortran_in_place_ is an extern variable, but it can't find where is the definition.
I use OpenMPI 4.0.4 and GCC 9.2.0 to compile the code and library, the operating system is CentOS Linux 7 (Core).
If you need more information, please let me know!
Thanks!

According to this commit, It seems that OpenMPI has no longer define mpi_fortran_in_place_ after version 3.0.
And I've successfully run the profiler by using OpenMPI 2.1.6.

Sorry for the late answer. I am surprised that the liballtoallv.so is having the symbol problem. I would prefer the undefined symbol to refer to Open MPI. I will have a look when possible.
