Hi Forum,
I know that this topic is widely discussed here to run shading language 4 with
OpenGL 3 and onwards using the compatibility profile. I checked the
osgsimplegl3 and osgvertexattrib array example. Then i try to compile the a
simple application with a pass through shader only , but i am having the
following error:
Code:
Got an X11ErrorHandling call display=0x9c41880 event=0xb3fadf2c
GLXBadDrawable
Major opcode: 135
Minor opcode: 11
Error code: 146

I am also attaching the code snippet for your kind review:
Code:
Hi Sajjadul,
1. add some window dimensions to the traits like:
traits->x = traits->y = 20;
traits->width = 800;
traits->height = 600;
2. set viewport to the camera
camera->setViewport(0,0,traits->width,traits->height);
3. you may also want to enable
gc->getState()->setUseModelViewAndProjectionUniforms(true);
