I cannot reproduce this warning on Qt port using gcc 4.5 on OpenSuSE 11.4. However I'll try to find a way to bypass this issue. 497720 4 yuqiang.xian 2011-11-07 21:35:51 -0800 Bug #71762 is created to fix the qt port build issue. 497739 5 barraclough 2011-11-07 22:05:12 -0800 Looks great, once the qt issue is fixed. When r71762 has landed, could you kick off a fresh EWS run, and then we can r+ once we have all green results. 497760 6 yuqiang.xian 2011-11-07 22:58:25 -0800 Adding another dependency - bug #71768. 497837 7 114009 yuqiang.xian 2011-11-08 01:13:20 -0800 Created attachment 114009 proposed patch Re-submit the patch as the dependencies should have been resolved. 497883 8 114009 fpizlo 2011-11-08 02:52:48 -0800 Comment on attachment 114009 proposed patch r=me. 497989 9 114009 yuqiang.xian 2011-11-08 05:48:47 -0800 Comment on attachment 114009 proposed patch Going to land it manually. 497995 10 yuqiang.xian 2011-11-08 05:54:11 -0800 Manually landed as r99559.

You did it right. I think it'll realize by the time it goes to commit that the cq flag was minus'd. And even if it didn't and you had already landed manually, then it should bail out because of conflicts. 498780 12 ossy 2011-11-09 03:42:27 -0800 FYI: Stricter compilers needs a buildfix for this patch.
