    OpenGL 3.0 in Catalyst 9.1

    Today ATI released Catalyst 9.1 driver with full OpenGL 3.0 context. I thought maybe it's time to move my code to 3.0 context. Tried to install new Catalyst and all I can say - I'm very disappointed.

    If I don't use WGL_ARB_create_context then all is ok - OGL 2.1 works fine. But if I try to create 3.0 context (it doesn't matter forward compatible or not) things gets "interesting":

    1) glGetString(GL_VERSION) crashes somewhere in atioglxx.dll file. glGetInteger(GL_MAJOR/MINOR_VERSION) works fine - returns 3.0
    2) glGetStringi(GL_EXTENSIONS, 1) returns NULL (also with any other valid extension number as second argument)
    3) glGetString(GL_SHADING_LANGUAGE_VERSION) in forward compatible context returns "1.20" instead of "1.30"

    I'm afraid to imagine what else there is broken if even simple things like getting version does not work...

    (this happens on Vista 32-bit, HD2400)

    ...

    what about the extension string when you create an OpenGL 2.1 context?

    Re: OpenGL 3.0 in Catalyst 9.1

    As I said - in OGL 2.1 everything works fine. If I skip WGL_ARB_create_context part and use context returned from wglCreateContext then everything runs fine:
    glGetString(GL_EXTENSIONS) returns normal string.
    Also glGetStringi(GL_EXTENSIONS, i) returns correct string values where i=0..glGetIntegerv(GL_NUM_EXTENSIONS)-1

    I was more expecting some kind of extension list to see if the feature are actually implemented.

    Re: OpenGL 3.0 in Catalyst 9.1

    Did somebody have successfully compiled fragment or vertex shader in forward compatible context with Catalyst 9.1?

    For any valid shader, even empty shader like this "void main() {}", I am getting compilation error with following text in log:
    Fragment shader compile error:
    Fragment shader failed to compile with the following errors:
    ERROR: compilation errors. No code generated.
    (same for vertex shader)

    In OpenGL 3.0 full context empty shader compiles fine.

    Re: OpenGL 3.0 in Catalyst 9.1

    This is not a valid shader. You have to set the value of the fragment color and the position of the vertex at least.

    Re: OpenGL 3.0 in Catalyst 9.1

    In full context such empty fragment shader works fine without error message
    I'm using empty fragment shader with shadow map rendering (using only depth attachment for FBO) in OGL2. Works fine till now. Is this really illegal?

    Ok, how about this fragment shader?
    Code :
    in vec3 fragment_color;
    out vec3 color;
    void main()
    {
        color = fragment_color;
    }

    Same error message.

    Also with following vertex shader:
    Code :
    in vec3 vertex_position;
    in vec3 vertex_color;
    out vec3 fragment_color;
    void main()
    {
       gl_Position = vec4(vertex_position, 1.0);
       fragment_color = vertex_color;
    }

    same error message.

    Note that these two shaders works fine with full GL3 context.
