This function is likely available... in the dynamic version of libnuma (that's why configure is happy), but make is probably trying to link with the static version which isn't available on your machine. That's my guess, at least. > I don't understand about make V=1. What tree? Somewhere in the OpenMPI build, > or in the application compilation itself?

Once you get the failure, please send the last 15 lines or so. We will look at these verbose lines to understand how things are being compiled (which linker flags, which libraries, ...) Brice
