OpenMPI Build Issues

Running "make check", the t_bigio test fails

When building HDF5 with OpenMPI 1.10.x, the t_bigio test will fail. The issue is due to a bug in the OpenMPI MPI datatype code that was fixed in current versions of OpenMPI 2.1.x, 3.0.x, 3.1.x, and 4.0.x and HDF5-1.10 was successfully tested with these versions (specifically, HDF5-1.10.x (where x=1 through 5) was tested with OpenMPI versions 2.1.5, 3.0.3, 3.1.3, and 4.0).  Following are the errors that occur if the tests fail with this issue:

You may or may not see output from other processes, depending on

Compiler complains about missing MPI calls

Please be aware that releases prior to HDF5-1.10.5 used MPI functions that were deprecated since MPI 2.0. With OpenMPI 4.0, those deprecated functions were deleted. This caused the compiler to complain about missing MPI calls. An example of APIs that have been deprecated are:  MPI_Type_extent, MPI_Address and MPI_Type_struct

To work around this issue build OpenMPI with MPI-1 backward compatibility. Otherwise the compiler will complain about the missing MPI calls.

The parallel flush test fails

Prior to HDF5-1.10.5 the parallel flush test failed. This failure can be ignored. Redirect the "make check" output to a file and use the "i" option to ignore errors:

make -i check >& check.output

Then view the output file (check.output) for any errors that occurred. If this is the only error, then you can ignore it:
