#1776: Wrong mpirun copied to utilities directory in MPI thorn -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Other | Version: development version Keywords: ExternalLibraries/MPI | -----------------------------------+---------------------------------------- On Mac OS, if I set MPI_DIR=BUILD in order to build OpenMPI using the MPI thorn, Cactus should copy the built version of mpirun into exe/<config>. However, if it finds one in /usr/local/bin, it copies that one instead.
NB: to compile OpenMPI, you need gnu99 or later in CFLAGS, as OpenMPI needs the 'asm' directive, which is a GNU extension.

Comment (by rhaas):
The recipe for the utilities (MPI/src/make.configuration.defn) reads: {{{ ALL_UTILS += $(shell cd $(MPI_DIR)/bin 2>/dev/null && ls mpirun ompi-clean ompi-iof ompi-probe ompi-profiler ompi-ps ompi-server ompi-top ompi_info 2>/dev/null) }}} and (MPI/src/make.configuration.deps) {{{ $(UTIL_DIR)/%: $(MPI_DIR)/bin/% @echo "Copying $* from $< to $(UTIL_DIR)" -$(MKDIR) $(MKDIRFLAGS) $(UTIL_DIR) 2> /dev/null cp $< $@ }}}
so as long as MPI_DIR is set properly (and detect.pl seems to do so) it should copy the correct executables. Can you check if perhaps homebrew itself sets and MPI_DIR environment variable which make take precendence?

Comment (by hinder):
I checked that there was no MPI_DIR set in the shell which I used to launch the build. I agree that detect.pl seems to be setting MPI_DIR correctly; the output indicates that the install location is correct, and from the code, this seems to propagate directly to the setting of MPI_DIR. Nonetheless, the wrong executable is copied, suggesting that by the time the code above gets called, something has changed MPI_DIR, or the code above is not working how it's supposed to. It's possible that if you put a dummy executable in /usr/local/bin/mpirun, you might be able to trigger the same behaviour on any system.
