[petsc-users] petsc 3.17 mpi configure issue

[Ben Pietras]

Hello,

If I run

$ ./configure --prefix=$PREFIX --with-mpi-dir=/opt/apps/mpi/gcc/openmpi/4.1.0-numa-ucx-1.9.0--gcc-4.8.5/ LDFLAGS=$LDFLAGS

I get

=============================================================================================
WARNING! Found environment variable: MPI_DIR=/opt/apps/mpi/gcc/openmpi/4.1.0-numa-ucx-1.9.0--gcc-4.8.5
Ignoring it! Use "./configure MPI_DIR=$MPI_DIR" if you really want to use this value
=============================================================================================

So, I try:

$  ./configure --prefix=$PREFIX --with-mpi-dir=/opt/apps/mpi/gcc/openmpi/4.1.0-numa-ucx-1.9.0--gcc-4.8.5/ LDFLAGS=$LDFLAGS MPI_DIR=$MPI_DIR

*********************************************************************************************
                        ERROR in COMMAND LINE ARGUMENT to ./configure
---------------------------------------------------------------------------------------------
The option MPI_DIR should probably be MPI-DIR

Then,

$ ./configure --prefix=$PREFIX --with-mpi-dir=/opt/apps/mpi/gcc/openmpi/4.1.0-numa-ucx-1.9.0--gcc-4.8.5/ LDFLAGS=$LDFLAGS MPI-DIR=$MPI_DIR
=============================================================================================
WARNING! Found environment variable: MPI_DIR=/opt/apps/mpi/gcc/openmpi/4.1.0-numa-ucx-1.9.0--gcc-4.8.5
Ignoring it! Use "./configure MPI_DIR=$MPI_DIR" if you really want to use this value                           =============================================================================================

My guess is that this is a bug (there is a '-' where it should be a '_').

If I'm mistaken, could I be advised how to correct?

Best,
Ben
