Hello,
Now that I am using empi/eselect-mpi, I would like to install boost-1.35.0
with its MPI library (it has an 'mpi' use flag).
When I try to emerge it, it trys to pull in sys-cluster/openmpi as a
dependency. I tried adding sys-cluster/openmpi to
/etc/portage/package.provided, but for some reason that does not work.
Any suggestions on how to get boost-mpi to build against my eselected
MPI? I also wonder if it would really be necessary build a version of boost
for each MPI package installed, using 'empi --add ...'. That seems like
overkill.
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?
