The user manual shows using `LD_PRELOAD` to insert the library, but that is Linux specific. There are two options: * Use `export DYLD_INSERT_LIBRARIES=/opt/local/lib/valgrind/libmpiwrap- amd64-darwin.so` before you call openmpirun. For this, you do not need to link your library. * Link against libmpiwrap-amd64-darwin.so and use `export DYLD_LIBRARY_PATH=/opt/local/lib/valgrind/` before you call openmpirun. -- Ticket URL: <http://trac.macports.org/ticket/26424#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS

That's it, thank you very very much for your help!

Hi, what is your Mac OS X's version? On my 10.6.8 Snowleopad, DYLD_LIBRARY_PATH does not work! When I 'otool -L' on the libmpiwrap-amd64-darwin.dylib, I saw there is no path only the filename for it. Even after I use 'install_name_tool -change ' on the helloworld executable (unfortunately, not work on the lib) to have the correct load path, I can not see the 'MPI wrappers' on the screen when I openmpirun it. It seems the library is loaded at runtime because there is no error message from 'ld' or 'dyld'. The output on the screen is just the same as without linking against the mpiwrap lib. -- Ticket URL: <https://trac.macports.org/ticket/26424#comment:7> MacPorts <http://www.macports.org/> Ports system for Mac OS
