General discussions / New version of glew

« on: January 14, 2010, 04:55:21 pm »

Is there a chance that the new version of glew could be included in SFML 2.0? I've had to use my own one, separately from sfml-window, ever since I started using OpenGL 3.2. The new version is available at http://glew.sourceforge.net/.

Window / ContextWGL crash after updating from 1.5 to 2.0 beta

« on: December 03, 2009, 07:43:17 pm »

I've tried searching the forums to see if someone else has been having this problem, but I didn't find anything.

My problem is that after updating my game from 1.5 to 2.0 it keeps crashing every time I exit the application. So I put together a minimal app to see if it still happens, and it does. I don't know whether it's an SFML issue, or a driver issue, or me screwing something up. I'm running the latest drivers for my graphics card.

So, the exact problem is that when I exit out of the app, it gives me an unhandled exception, and the issue appears to be on line 91 of ContextWGL.cpp:

Code: [Select]

   if (myContext)
    {
        if (wglGetCurrentContext() == myContext)
---->       wglMakeCurrent(NULL, NULL);
        wglDeleteContext(myContext);
    }

My call stacks looks like this:

    

Code: [Select]

   atioglxx.dll!6903a3ad()
  [Frames below may be incorrect and/or missing, no symbols loaded for atioglxx.dll]
  atioglxx.dll!690925d5()
  opengl32.dll!676e9286()
  opengl32.dll!676e9583()

  sfml-window-d.dll!_CRT_INIT(void * hDllHandle=0x00100000, unsigned long dwReason=0x00000000, void * lpreserved=0x00000001)  Line 449 C
  sfml-window-d.dll!__DllMainCRTStartup(void * hDllHandle=0x00100000, unsigned long dwReason=0x00000000, void * lpreserved=0x00000001)  Line 560 + 0x11 bytes C
  sfml-window-d.dll!_DllMainCRTStartup(void * hDllHandle=0x00100000, unsigned long dwReason=0x00000000, void * lpreserved=0x00000001)  Line 510 + 0x11 bytes C


And the code for my minimal program looks like this:

Code: [Select]

#include <SFML/Window.hpp>

int main()
{
sf::VideoMode mode;
mode.Width = 1280;
mode.Height = 800;
mode.BitsPerPixel = 32;

sf::Window Screen;
Screen.Create(mode, "oglgame");

return 0;
}

I'm going to feel really stupid if I'm just missing a line or two.

Edit: If I run in release instead of debug it instead seems to crash in crtdll.c on line 449:

Code: [Select]

                       /* call the function, which can eventually change __onexitbegin and __onexitend */
                        (*function_to_call)();

         ---->          onexitbegin_new = (_PVFV *)_decode_pointer(__onexitbegin);
                        onexitend_new = (_PVFV *)_decode_pointer(__onexitend);

And the call stack then looks like this:

Code: [Select]

atioglxx.dll!6903a3ad()
  [Frames below may be incorrect and/or missing, no symbols loaded for atioglxx.dll]
  atioglxx.dll!690925d5()
