Hi George and Chris, The QThread support was submitted initially for the further migrating to Symbian and Meego. AFAIK, the Meego version of OSG is already workable in a Chinese lab. But I don't have a clear plan of when and how to merge it to the trunk version at present.
And yes, until the 4.7 release, Qt doesn't support setting CPU affinity so far. And I'm not sure if Qt's threading model is safer or not. But at least, it should be a good start for porting OSG to another few mobile platforms. :-) Wang Rui 2011/7/5 Chris 'Xenon' Hanson <[email protected]>: > On 7/5/2011 4:03 AM, George Bekos wrote: >> Hello again guys! :D >> I want to ask you about this "BUILD_OPENTHREADS_WITH_QT" CMake flag when you >> build OSG.
