I have heard very good things about fftwpp recently and am very curious to try it out.  I thought there was a wrapper for python.  If yes do you have any advice on how one might set this up?  If no maybe it's too much work.\r\n\r\nThanks for putting this together, it looks really great!\r\n\r\nFrancis"},"comment":{"url":"https://api.github.com/repos/dealias/fftwpp/issues/comments/157948232","html_url":"https://github.com/dealias/fftwpp/issues/2#issuecomment-157948232","issue_url":"https://api.github.com/repos/dealias/fftwpp/issues/2","id":157948232,"user":{"login":"johncbowman","id":13231852,"avatar_url":"https://avatars.githubusercontent.com/u/13231852?v=3","gravatar_id":"","url":"https://api.github.com/users/johncbowman","html_url":"https://github.com/johncbowman","followers_url":"https://api.github.com/users/johncbowman/followers","following_url":"https://api.github.com/users/johncbowman/following{/other_user}","gists_url":"https://api.github.com/users/johncbowman/gists{/gist_id}","starred_url":"https://api.github.com/users/johncbowman/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/johncbowman/subscriptions","organizations_url":"https://api.github.com/users/johncbowman/orgs","repos_url":"https://api.github.com/users/johncbowman/repos","events_url":"https://api.github.com/users/johncbowman/events{/privacy}","received_events_url":"https://api.github.com/users/johncbowman/received_events","type":"User","site_admin":false},"created_at":"2015-11-19T04:30:29Z","updated_at":"2015-11-19T04:30:29Z","body":"Try linking with -lgomp\n\n\nOn Wed, Nov 18, 2015 at 7:51 PM, francispoulin <notifications@github.com>\nwrote:\n\n> Thanks for the quick reply.\n>\n> I tried it on my ubuntu machine and it compiled easily and ran fast.
