#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.
