Here's some additional information that may be useful. So what am I doing wrong? Why doesn't Mesa 10.1 support OpenGL 3.3 for me? My graphics card certainly supports it. I can set GLFW_OPENGL_VERSION_MINOR to 0 and then the window opens fine, but an exception will be thrown later as GLSL 3.3 shaders are required.Īlso note that the rendering engine runs fine when I use the proprietary fglrx drivers (and then glxinfo reports OpenGL version 4.2), so the application itself really is not the problem, but the supported OpenGL is. When I try to run the rendering engine using this setup, the above exception gets thrown as OpenGL 3.3 is not supported. THROW("GLFW error: failed to create window.") _windowDimensions.x, _windowDimensions.y, GlfwOpenWindowHint(GLFW_OPENGL_PROFILE, 0) GlfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3) I use the following code to spawn a window: glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3) I am aware that glxinfo may report the wrong version numbers as per the Mesa 10.1 Release Notes, however the rendering engine I'm trying to run fails because of this. ![]() Why is that? How can I enable OpenGL 3.3? As can be seen by comparison in the StackOverflow thread that I mentioned, it is possible to have glxinfo report OpenGL 3.3. OpenGL shading language version string: 1.30 OpenGL version string: 3.0 Mesa 10.1.0-devel (git-7f57408 saucy-oibaf-ppa+curaga) OpenGL core profile context flags: (none) OpenGL core profile shading language version string: 1.40 OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.0-devel (git-7f57408 saucy-oibaf-ppa+curaga) OpenGL renderer string: Gallium 0.4 on AMD CAYMAN However, glxinfo, while it now reports that Mesa 10.1 is in use, still reports only OpenGL 3.0 (compat profile) and OpenGL 3.1 (core profile): $ glxinfo | grep OpenGL $ sudo add-apt-repository ppa:oibaf/graphics-driversģ.) Dist-upgrade (rebuilds many packages) I used the exact same steps as explained there: 1.) Add the PPA Repository StackOverflow: OpenGL & GLSL 3.3 on an HD Graphics 4000 under Ubuntu 12.04 It is however possible to install Mesa 10.1 (implementing OpenGL 3.3) from this PPA as explained in this thread: Ubuntu 13.10 only provides Mesa 9.2 (implementing OpenGL 3.1) "out of the box". I want to use the open source drivers ( radeon), which rely on Mesa for their OpenGL implementation. I am trying to get an OpenGL-based rendering engine that relies on OpenGL 3.3 and GLSL 3.3 to run on Ubuntu 13.10 using an AMD Radeon 6950.
