Out of interest how does open-mpi handle the mpir_dll_name symbol in
the
library, it's supposed to contain the location of the debugger library
and therefore does not play well with relocating RPMs or installed
library's other to the place they were built for.
Today, it does not -- the location has to be compile-time
initialized. So if you move the library+plugin somewhere else, the
Etnus scheme to find the DLL currently cannot handle it.
We have proposed a new scheme to Etnus and Allinea that allows a bit
more flexibility to find the DLLs at run-time; both have agreed to the
idea in principle. We will include this support in Open MPI v1.3; I
don't know when/if the debuggers will support it. I believe that the
ball is currently in my court; Etnus asked me some questions to which
I have not yet replied... doh...
