As I don't intend to develop for 10.7 or above I stayed with 3.2.6. In the beginning Xcode wasn't free and so I didn't look into it. I can also compile the latest Open MPI 1.6.3 with the above version. > I think that the reason why nothing happens is because the code runs via > MPICH2; tried to launch mpicc with the -echo flag and i see in the output > > -I/opt/local/include/mpich2 -L/opt/local/lib -lpmpich -lmpich -lopa -lmpl > -lpthread Yep. -- Reuti > which makes me think that i am using MPICH2; I just need to figure out how to > remove it now...found a dir in opt/local/include that is called mpich2 but I > am not sure if is enough to just delete that dir. > > > When I have installed OpenMPI I followed the instructions on this site: > > https://sites.google.com/site/dwhipp/tutorials/installing-open-mpi-on-mac-os-x > > While for MPICH2 I've followed this one: > > http://www.mpitutorial.com/installing-mpich2/ > > Most likely I've put them on top of each other and messed up both > > > > On Nov 9, 2012, at 2:32 AM, Reuti wrote: > >> Am 09.11.2012 um 08:47 schrieb shiny knight: >> >>> Thanks for your replies. >>> >>> I use Snow Leopard, running ompi_info returns an error (command not found). >> >> I'm on this version too.
