Hi all,
Until Open MPI 1.3 (maybe 1.3.1), I used to find it convenient to be able
to move a library from its "normal" place (either /usr or /opt) to
somewhere else (i.e. my NFS home account) to be able to try things only on
my account.
So, I used to set OPAL_PREFIX to the root of the Open MPI directory and
all went fine.
I don't know if relocation was intended in the first place, but with
1.3.2, this seems to be broken.
It may have something to do with this patch (and maybe others) :

All the OPAL_ defines from the install_dirs.h contain ABSOLUTE path.
Therefore,
there is no need to prepend OPAL_PREFIX to them.

George, is there a rationale behind this patch for disabling relocation of
libraries ? Do you think reverting only this patch would bring back the
relocation functionality ?
TIA,
Sylvain
