[Mvapich-discuss] Build failure with NVHPC compilers

[Subramoni, Hari]

Hi, Martin.

Sorry to hear that you’re facing this issue. I think we had resolved some of these with the latest MVAPICH2 2.3.7 release. Could you please try that and let us know?

Best,
Hari.

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 ZjQcmQRYFpfptBannerStart

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

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,
