OpenMPI 5.0.0 & Intel OneAPI 2023.2.0 on MacOS 14.0: In an ostensibly clean system, the following configure on MacOS ends without a viable pmix build:
configure: WARNING: Either libevent or libev support is required, but neither configure: WARNING: was found. Please use the configure options to point us configure: WARNING: to where we can find one or the other library configure: error: Cannot continue configure: ===== done with 3rd-party/openpmix configure ===== checking for pmix pkg-config name... pmix checking if pmix pkg-config module exists... yes checking for pmix pkg-config cflags... -I/usr/local/Cellar/open-mpi/4.1.5/include checking for pmix pkg-config ldflags... -L/usr/local/Cellar/open-mpi/4.1.5/lib checking for pmix pkg-config static ldflags... -L/usr/local/Cellar/open-mpi/4.1.5/lib checking for pmix pkg-config libs... -lpmix -lz checking for pmix pkg-config static libs... -lpmix -lz checking for pmix.h... no configure: error: Could not find viable pmix build. configure command used was: lt_cv_ld_force_load=no ./configure --prefix=/usr/local/openmpi/5.0.0 FC=ifort F77=ifort CC=icc CXX=icpc *** The same command works (up to the end of the configure stage) with OpenMPI 4.1.6. My guess is that this is related to some earlier pmix related issues that can be found by google but wanted to report. Thank you!
