I run it on ubuntustudio 10.04, with a rt-kernel that I compiled, but this problem happens also with ubuntu generic kernel.

This segmentation fault happens since several weeks with previous svn versions.

After reading this http://vdrift.net/Forum/viewtopic.php?t=1371 I changed glGenerateMipmapEXT(GL_TEXTURE_CUBE_MAP) to glGenerateMipmap(GL_TEXTURE_CUBE_MAP) in texture.cpp but the output is the same.

The glew version should be 1.5.4 I think. I wonder if there is a way to check the glew version before linking.

Another related thread: http://vdrift.net/Forum/viewtopic.php?t=1384

I updated glew to 1.5.6 :

Replace GL_EXT_framebuffer_object with GLEW_ARB_framebuffer_object in texture.cpp line 280.

- NaN - 09-22-2010

Can you also try GLEW_EXT_framebuffer_object. Thanks.

- skankerror - 09-22-2010

Well...

with GLEW_ARB and GLEW_EXT I have no more seg fault.

Instead I have black window with some blue at right side and this output repeating endless:

Code:
ERROR: OpenGL error "invalid operation" during: render finish

ERROR: OpenGL error "invalid operation" during: render finish

ERROR: OpenGL error "invalid operation" during: render finish

ERROR: OpenGL error "invalid operation" during: render finish

ERROR: OpenGL error "invalid operation" during: render finish

ERROR: OpenGL error "invalid operation" during: render finish

I was thinking about a problem whith my glew update (I used ugly 'dpkg --force-overwrite'), so I downgraded to a clean ubuntu libglew 1.5.2 but nothing changed.

- NaN - 09-22-2010

Interesting. We need to identify the call causing an "invalid operation".

Have a look at graphics.cpp line 351: void GRAPHICS_SDLGL::BeginScene(std::ostream & error_output)

Can you insert OPENGL_UTILITY::CheckForOpenGLErrors after each gl.... call to see which one fails.

- skankerror - 09-22-2010

I think I need some C++ lessons, I've made this :

Code:
void GRAPHICS_SDLGL::BeginScene(std::ostream & error_output)

{

    glstate.Disable(GL_TEXTURE_2D);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glShadeModel( GL_SMOOTH );

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glClearColor(0,0,0,0);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glClearDepth( 1.0f );

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glstate.Enable(GL_DEPTH_TEST);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glDepthFunc( GL_LEQUAL );

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST );

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glstate.Disable(GL_LIGHTING);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glstate.SetColor(0.5,0.5,0.5,1.0);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glPolygonOffset(-1.0,-1.0);

    OPENGL_UTILITY::CheckForOpenGLErrors;

    glClear (GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    OPENGL_UTILITY::CheckForOpenGLErrors("BeginScene", error_output);

}

and when compiling :

Code:
src/graphics.cpp: In member function âvoid GRAPHICS_SDLGL::BeginScene(std::ostream&)â:

I stopped this cos I must be wrong...

Copy paste: OPENGL_UTILITY::CheckForOpenGLErrors("BeginScene", error_output);

Replace "BeginScene" with a unique string per call ("1", "2", ...).
