Re: [Valgrind-users] compiling with MPI support on OS X Lion

[Dave G. <go...@mc...>]

That looks like it's working to me, at least for a 64-bit architecture.  The "failure" in the config.log that you have posted is for the 32-bit side of things.  Valgrind builds bi-arch, but MPI implementations generally don't.  So in practice you won't get bi-arch MPI wrappers unless you hack things up quite a bit.

Have you tried actually using the valgrind MPI wrappers with your new valgrind?  It should just work now.  (I assume that the configure and make steps are completing properly.)
