Any reasonably recent Clang version (at > least 2.9) should support both switches. My concern is the boxes on which nouveau works fine but have older compilers (I'm thinking of RHEL or Ubuntu LTS style situations). I want those to work a lot more than I want nouveau to build on FreeBSD/OSX/whatever. IIRC tr1 support came with GCC 4.0 or 4.1 or so, but I don't know which compilers came with which distros. I guess mesa already requires gcc 4.2 for something, so moving that up to 4.3 for nouveau may not be such a huge deal. I guess a patch which turns on -std=c++0x for codegen would be fine by me.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
