Hi Thomas, thank you for your response. I'm primarily a user of OpenACC. Sorry, I'm a little newbie about GCC building, could you post here a simple list of commands in order to building GCC 4.9 with openacc support?
I've found this: http://gcc.1065356.n5.nabble.com/OpenACC-or-OpenMP-4-0-target-directives-td986517.html but I get an error when I type "git fetch"... Thank you in any case. Paolo L.
