I think we have seen this before. The configure test just checks to see if the compiler doesn't barf on -fopenmp? The Apple clang compiler accepts that flag but doesn't actually support openmp IIRC. Daniel, can you send your config.log to me directly (or share as a google doc)? I'd like to see the output of configure for that test. -- John ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
