Having issues with OpenGL versions in C++. Using SFML1.6/GLEW.

[squeakyneb]

I'm trying to learn modern OpenGL with the OGL Wikibook. I created a Window just fine with SFML, like I did back when I learnt with immediate mode. I tried creating a shader and it failed at runtime. I wrote some code to dump potentially useful data.

std::cout << "BEGIN!" << std::endl;
sf::WindowSettings winsettings;
winsettings.AntialiasingLevel=8;
winsettings.DepthBits=24;
winsettings.StencilBits=8;
sf::Window AppWindow(sf::VideoMode::GetDesktopMode(),"EITBSGBEAB, DV",sf::Style::Fullscreen,winsettings);

AppWindow.ShowMouseCursor(true);
AppWindow.EnableKeyRepeat(true);
AppWindow.SetActive();

std::cout << "VENDOR:    " << glGetString(GL_VENDOR) << std::endl;
std::cout << "VERSION:   " << glGetString(GL_VERSION) << std::endl;
std::cout << "RENDERER:  " << glGetString(GL_RENDERER) << std::endl;
std::cout << "GLEW 2.0:  " << (GLEW_VERSION_2_0!=0) << std::endl;
std::cout << "GLEW 2.1:  " << (GLEW_VERSION_2_1!=0) << std::endl;
//std::cout << "EXTENSIONS:" << glGetString(GL_EXTENSIONS) << std::endl;
if(!GLEW_VERSION_2_0)
{
    std::cout << "OpenGL 2.0 support is nonexistant! :O" <<std::endl;
    return 1;
}

Glewinfo.exe says everything up to to 4.1 is "ok" with my card, my code does say 4.2 but maybe "compatibility mode" counteracts that. I'm thinking it might be something wrong with the way I'm creating the window, but I would've thought SFML would do it right.
Any ideas?

Have you called glewInit() first?

[squeakyneb]

No, I haven't. I assumed that whatever it was doing was helping GLUT set up the window and SFML would've dealt with it. I'll give a success report once I fix this linking issue (was told linking directly to the DLL works, turns out it doesn't quite work, attempting recompile of GLEW under MinGW).

Thanks Laurent, you're a damn magician

Calling glewInit() for GLEW to work, as stated in its documentation, is not what I call "magic"
