[Darshan-users] Darshan installation question

[Kevin Harms]

Ketan,

  first thing, check that the library was linked in. Try nm exe | grep darshan and see if any darshan symbols are present. If they are, see if there is any output on standard error indicating the darshan log couldn't be opened.

  If darshan isn't being linked in, are you also trying to use Tau or have other libraries that might intercept MPI routines.
