Having added openmpi to /etc/portage/profile/package.provided, I can emerge boost with mpi, but the mpi autodetect fails during the compilation with this message: MPI auto-detection failed: unknown wrapper compiler mpic++ The same occurs if I run 'ebuild ... compile'. But if I run the same command as root from the resulting /var/tmp/.../work directory, the detection is successful. Any ideas what might be going on here? What part of the ebuild environment changes such that it does not see mpic++ anymore? -bryan -- gentoo-cluster@lists.gentoo.org mailing list
