Hi, managed to compile latest osg debug on linux ( possible cmake-gui made some some strange things after severl reconfigurations - absolutely clean svn code compiled just fine ).
but still the same error in osgviewer ( now osgviewerd ) with OpenGL ES 2.0 enabled > GraphicsWindowX11::init() - eglInitialize() succeded eglMajorVersion=1 > iMinorVersion=4 > GraphicsWindowX11::init() - window created =1 > Warning: TexGen::apply(State&) - not supported. > Warning: Material::apply(State&) - not supported. > Warning: TexGen::apply(State&) - not supported. I will look with debugger tomorrow. but a small question - is such output is expected on linux or is it osg bug?
