[Mvapich-discuss] catastrophic error: cannot open source file "src/pm/hydra/include/hydra_config.h"

[Long, James W]

Trying to build mvapich2 version 2.3.6 with a fairly straight forward configure / make
sequence including "—with-pm=mpirun" results in hydra_config.h not being created
during the configure, which in turn leads to a compilation error during the make.


./configure CC=icc CXX=icpc F77=ifort FC=ifort --with-pm=mpirun --enable-f77 --enable-fc --enable-cxx --prefix=/usr/local/mpi/mvapich2/mvapich2-2.3.6-intel-2019.5-test

If the “—with-pm=mpirun” argument is omitted, the configure / make sequence completes without an error and I see the
following lines in the output of the configure command -

configure: creating ./config.status
config.status: creating tools/topo/hwloc/hwloc/Makefile
config.status: creating tools/topo/hwloc/hwloc/include/Makefile
config.status: creating tools/topo/hwloc/hwloc/src/Makefile
config.status: creating Makefile
config.status: creating tools/bootstrap/src/bsci_init.c
config.status: creating hydra-doxygen.cfg
config.status: creating include/hydra_config.h


If I then go back and rerun the original configure command, with the “—with-pm=mpirun” argument in place, and 
the hydra_config.h file pre-existing from the previous configure command,
the configure / make sequence proceeds without error.

I tried this with version 2.3.5 and got the same result.
