This was for GLEW_EXT in texture.cpp

For GLEW_ARB here's gdb output :

It happens during shadow camera setup graphics.cpp line 804-820. Do you mind to insert opengl error checks there to see which gl call is causing problems.

You could also try to comment out the shadow camera setup loop. Shadows need shaders anyway.

skankerror · 09-22-2010, 05:42 PM,

Thanks for help NaN.

After commenting out camera setup loop game is working (very slow with a lot of ERROR: OpenGL error "invalid operation" during: render finish).

I don't have time to go further now, but as soon as possible I'll insert some opengl error checks, I think I understand how it works.

skankerror · 09-23-2010, 04:16 PM,

Code:
// create cameras for shadow passes

    std::vector <std::string> shadow_names;

    shadow_names.push_back("near");

    shadow_names.push_back("medium");

    shadow_names.push_back("far");

    OPENGL_UTILITY::CheckForOpenGLErrors("7", std::cerr);

    for (int i = 0; i < 3; i++)

    {

        float shadow_radius = (1<<i)*closeshadow+(i)*20.0; //5,30,60

        OPENGL_UTILITY::CheckForOpenGLErrors("8", std::cerr);

        MATHVECTOR <float, 3> shadowbox(1,1,1);

        OPENGL_UTILITY::CheckForOpenGLErrors("9", std::cerr);

        shadowbox = shadowbox * (shadow_radius*sqrt(2.0));

        OPENGL_UTILITY::CheckForOpenGLErrors("10", std::cerr);

        MATHVECTOR <float, 3> shadowoffset(0,0,-1);

        OPENGL_UTILITY::CheckForOpenGLErrors("11", std::cerr);

        shadowoffset = shadowoffset * shadow_radius;

        OPENGL_UTILITY::CheckForOpenGLErrors("12", std::cerr);

        (-cam_rotation).RotateVector(shadowoffset);

        OPENGL_UTILITY::CheckForOpenGLErrors("13", std::cerr);

        shadowbox[2] += 60.0;

        OPENGL_UTILITY::CheckForOpenGLErrors("14", std::cerr);

        GRAPHICS_CAMERA & cam = cameras["shadows_"+shadow_names[i]];

        OPENGL_UTILITY::CheckForOpenGLErrors("15", std::cerr);

        cam = cameras["default"];

        cam.orthomode = true;

        cam.orthomin = -shadowbox;

        cam.orthomax = shadowbox;

        cam.pos = cam.pos + shadowoffset;

        cam.orient = lightdirection;

        OPENGL_UTILITY::CheckForOpenGLErrors("16", std::cerr);

        // go through and extract the clip matrix, storing it in a texture matrix

        renderscene.SetOrtho(cam.orthomin, cam.orthomax);

        renderscene.SetCameraInfo(cam.pos, cam.orient, cam.fov, cam.view_distance, cam.w, cam.h, false);

        float mv[16], mp[16], clipmat[16];

        glGetFloatv( GL_PROJECTION_MATRIX, mp );

        glGetFloatv( GL_MODELVIEW_MATRIX, mv );

        glMatrixMode( GL_TEXTURE );

        glPushMatrix();

        glLoadIdentity();

        glTranslatef (0.5, 0.5, 0.5);

        glScalef (0.5, 0.5, 0.5);

        glMultMatrixf(mp);

        glMultMatrixf(mv);

        glGetFloatv(GL_TEXTURE_MATRIX, clipmat);

        glPopMatrix();

        glMatrixMode( GL_MODELVIEW );

        glActiveTexture(GL_TEXTURE4+i);

        glMatrixMode( GL_TEXTURE );

        glLoadMatrixf(clipmat);

        glMatrixMode( GL_MODELVIEW );

        glActiveTexture(GL_TEXTURE0);

        }

    OPENGL_UTILITY::CheckForOpenGLErrors("after setup", std::cerr);

}

Here's where I inserted some opengl errors checks, and here's output :

OpenGL error "invalid operation" during: 8
OpenGL error "invalid operation" during: 8
OpenGL error "invalid operation" during: after setup
ERROR: OpenGL error "invalid operation" during: render finish

...

I hope this can help.

The interesting part is:

Code:
glGetFloatv( GL_PROJECTION_MATRIX, mp );

      glGetFloatv( GL_MODELVIEW_MATRIX, mv );

      glMatrixMode( GL_TEXTURE );

      glPushMatrix();

      glLoadIdentity();

      glTranslatef (0.5, 0.5, 0.5);

      glScalef (0.5, 0.5, 0.5);

      glMultMatrixf(mp);

      glMultMatrixf(mv);

      glGetFloatv(GL_TEXTURE_MATRIX, clipmat);

      glPopMatrix();

      glMatrixMode( GL_MODELVIEW );

      glActiveTexture(GL_TEXTURE4+i);

      glMatrixMode( GL_TEXTURE );

      glLoadMatrixf(clipmat);

      glMatrixMode( GL_MODELVIEW );

      glActiveTexture(GL_TEXTURE0);

I could be that we are trying to access texture units beyond GL_MAX_TEXTURE_UNITS. Can you post your glxinfo.

NaN Wrote:It could be that we are trying to access texture units beyond GL_MAX_TEXTURE_UNITS.

Good call! That's got to be it. There's no reason to be doing the shadow set up with shaders off, so I added code to not do that bit in R2862. See if that fixes it for you.

In R2862 I have a seg fault too.
By replacing GL_EXT_framebuffer_object by GLEW_EXT_framebuffer_object in texture.cpp, game is working.

I inserted this in graphics.cpp :

Code:
// go through and extract the clip matrix, storing it in a texture matrix

            renderscene.SetOrtho(cam.orthomin, cam.orthomax);

            renderscene.SetCameraInfo(cam.pos, cam.orient, cam.fov, cam.view_distance, cam.w, cam.h, false);

            float mv[16], mp[16], clipmat[16];

            OPENGL_UTILITY::CheckForOpenGLErrors("1", std::cerr);

            glGetFloatv( GL_PROJECTION_MATRIX, mp );

            OPENGL_UTILITY::CheckForOpenGLErrors("2", std::cerr);

            glGetFloatv( GL_MODELVIEW_MATRIX, mv );

            OPENGL_UTILITY::CheckForOpenGLErrors("3", std::cerr);

            glMatrixMode( GL_TEXTURE );

            OPENGL_UTILITY::CheckForOpenGLErrors("4", std::cerr);

            glPushMatrix();

            OPENGL_UTILITY::CheckForOpenGLErrors("5", std::cerr);

            glLoadIdentity();

            OPENGL_UTILITY::CheckForOpenGLErrors("6", std::cerr);

            glTranslatef (0.5, 0.5, 0.5);

            OPENGL_UTILITY::CheckForOpenGLErrors("7", std::cerr);

            glScalef (0.5, 0.5, 0.5);

            OPENGL_UTILITY::CheckForOpenGLErrors("8", std::cerr);

            glMultMatrixf(mp);

            OPENGL_UTILITY::CheckForOpenGLErrors("9", std::cerr);    

            glMultMatrixf(mv);

            OPENGL_UTILITY::CheckForOpenGLErrors("10", std::cerr);

            glGetFloatv(GL_TEXTURE_MATRIX, clipmat);

            OPENGL_UTILITY::CheckForOpenGLErrors("11", std::cerr);

            glPopMatrix();

            OPENGL_UTILITY::CheckForOpenGLErrors("12", std::cerr);

            glMatrixMode( GL_MODELVIEW );

            OPENGL_UTILITY::CheckForOpenGLErrors("13", std::cerr);

            glActiveTexture(GL_TEXTURE4+i);

            OPENGL_UTILITY::CheckForOpenGLErrors("14", std::cerr);

            glMatrixMode( GL_TEXTURE );

            OPENGL_UTILITY::CheckForOpenGLErrors("15", std::cerr);

            glLoadMatrixf(clipmat);

            OPENGL_UTILITY::CheckForOpenGLErrors("16", std::cerr);

            glMatrixMode( GL_MODELVIEW );

            OPENGL_UTILITY::CheckForOpenGLErrors("17", std::cerr);

            glActiveTexture(GL_TEXTURE0);

            OPENGL_UTILITY::CheckForOpenGLErrors("18", std::cerr);

But the only output remains : ERROR: OpenGL error "invalid operation" during: render finish Sad

@joe
RENDER_INPUT_SCENE::Render is using PushShadowMatrices/PopShadowMatrices I guess it needs a shadows enabled bit too.

@skankerror
Can you look for PushShadowMatrices()/PopShadowMatrices() calls and comment them out.

skankerror · 09-26-2010, 05:50 AM,

PushShadowMatrices()/PopShadowMatrices() calls commented out :

No more openGL error (with GLEW_EXT and GLEW_ARB).
Original texture.cpp still causes seg fault.

Done, R2864.
