[Mvapich-discuss] Build failure with NVHPC compilers

[Martin Cuma]

We're building MVAPICH2 2.3.6, either with Spack or separately, but we get the following error:

libtool: link: nvc -DNDEBUG -DNVALGRIND -O2 -rdynamic -o src/pm/mpirun/mpirun_rsh src/pm/mpirun/mpirun_rsh.o src/pm/mpirun/mpirun_util.o src/pm/mpirun/mpmd.o src/pm/mpirun/mpirun_dbg.o src/pm/mpirun/mpirun_ckpt.o src/pm/mpirun/mpirun_params.o src/pm/mpirun/param.o src/pm/mpirun/signal_processor.o src/pm/mpirun/wfe_mpirun.o src/pm/mpirun/m_state.o src/pm/mpirun/read_specfile.o src/pm/mpirun/gethostip.o src/pm/mpirun/environ.o src/mpid/ch3/channels/common/src/util/mv2_config.o src/mpid/ch3/channels/common/src/util/crc32h.o src/mpid/ch3/channels/common/src/util/error_handling.o src/mpid/ch3/channels/common/src/util/debug_utils.o  -lm src/pm/mpirun/src/hostfile/libhostfile.a src/pm/mpirun/src/db/libdb.a src/pm/mpirun/src/slurm/libslurm.a src/pm/mpirun/src/slurm/libnodelist.a src/pm/mpirun/src/slurm/libtasklist.a src/pm/mpirun/src/pbs/libpbs.a -lrt -lpthread

nvc-Error-Unknown switch: -rdynamic
nvc-Error-Unknown switch: -rdynamic

It looks like the configure injects the -rdynamic flag, which is not present in NVHPC (=PGI) compilers, into the LDFLAGS for the mpirun builds:

$ grep rdynamic *
Makefile:src_pm_mpirun_mpirun_rsh_LDFLAGS = -rdynamic
Makefile:src_pm_mpirun_mpiexec_mpirun_rsh_LDFLAGS = -rdynamic
Makefile:src_pm_mpirun_mpispawn_LDFLAGS = -rdynamic

Is there anything we can do about this to enable this build to succeed, or will it be necessary to edit the configure script?

Thanks,
