[solved] OpenGL: Could not find FB config.

(1/2) > >>

Ocye:
I use LazOpenGLContext successfully for some time. But after one of the recent LCL updates, I get the mentioned error when the context becomes visible. The example runs perfectly. However, I don't do any advanced stuff. Just standard Gl and Glu. Any idea where to look for the problem?

Lazarus 1.1 r37618 FPC 2.6.0 x86_64-linux-qt (compile target is gtk2)
Linux version 3.3.8-1-ARCH (tobias@T-POWA-LX) (gcc version 4.7.0 20120505 (prerelease) (GCC) ) #1 SMP PREEMPT Tue Jun 5 15:20:32 CEST 2012

Ocye:
It works if I replace changes in gdk_gl_context_share_new() with rev 37115. Is attrList[] really assigned to valid data?


--- Code: ---{$IFDEF UseFPGLX}
  FBConfig: TGLXFBConfig;
  FBConfigs: PGLXFBConfig;
  FBConfigsCount: Integer;

  { Attributes to choose context with glXChooseFBConfig.
    Similar to Attr, but not exactly compatible. }
  AttrFB: Array[0..10] of integer = (
            GLX_X_RENDERABLE, 1 { true },
            GLX_RED_SIZE, 1,
            GLX_GREEN_SIZE, 1,
            GLX_BLUE_SIZE, 1,
      GLX_DOUBLEBUFFER, 1 { true },
      none);
{$ENDIF}
...
FBConfigs:=glXChooseFBConfig(dpy, DefaultScreen(dpy), AttrFB, FBConfigsCount);

--- End code ---

Hi.
Perhaps this patch solves the problem?

Ocye:
No, FBConfigsCount is still 0 (rev 37777 with patch).

I also get this error when dynamically creating OpenGLContext in OnCreate form handler. If moved it to OnShow all starts working
