Re: [osg-users] Error in the new version OSG
Hi Maxim, Very strange. The threading part of osgViewer hasn't changed, and OpenThreads under Linux hasn't changed, I don't think there is any recent changes on the OSG side that might have introduced problems. Doing the exactly same test on my system doesn't result in any problems. My best guess is that there is some driver issue on your system which is causing a failure to create the required graphics context. As I suggest before getting a strack and looking at where the crash happens might provide some clues. Robert. 2011/5/2 Maxim Gammer maxgam...@gmail.com: Hi Robert, I checked, the result has not changed ... osgviewer ./osgcool.osg Error: In Texture::Extensions::setupGLExtensions(..) OpenGL version test failed, requires valid graphics context.

Re: [osg-users] Error in the new version OSG
Hi Maxim, 2011/5/3 Maxim Gammer maxgam...@gmail.com: How to get information about error? I must use Valgrind? I would start by just running osgviewer in gdb i.e. gdb osgviewer run osgcool.osg You could learn valigrind but I suspect the issue isn't really to do with threading in the core OSG as little has changed. Given the context errors being reported it looks more like something lower level is going wrong.
