No, it just means OGL 1.x contexts instead of OGL 3.x context for cards supporting it.

Okay, thanks for clarification.

By the way, pixel-perfect rendering works flawlessly.

Sadly I still have this problem on Arch Linux, Msi Wind 120. I feel... Alone

Ps. The one with glxcontext message

I narrowed the error to sf::Window constructor. The error also appears in RenderWindow.
The below code triggers the error.

Code: [Select]


#include <SFML/Window,hpp>

int main()
{
     sf::Window window
}

Thanks for your help.

I have a clue (two actually), but I'll have to do more tests to figure it out.

With valgrind, I get this :

Code: [Select]

It might help ?

I still have the same error on my Laptop (ATI Radeon Xpress 1100). However, on my PC (Nvidia) it works.

Lokk · « **Reply #67 on:** September 26, 2009, 01:26:26 am »

I tried the last ATI Radeon drivers (9.9) but the error still occurred.

I've still got the problem on my laptop, too:

Code: [Select]

  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)

Some news ? I haven't found any answer on my side.

Laurent · « **Reply #70 on:** October 02, 2009, 08:49:52 pm »

I didn't have time for that yet, but I'll try to look into it soon.

Tank · « **Reply #71 on:** October 05, 2009, 11:38:39 pm »

Don't know if this helps, but the application seems to crash at line 133 in the file src/SFML/Window/Linux/ContextGLX.cpp:

Code: [Select]

return glXMakeCurrent(myDisplay, myWindow, myContext) != 0;
The error code says "GLXBadContext".

Laurent · « **Reply #72 on:** October 06, 2009, 08:42:59 am »

That's weird, the error you previously reported is about X_GLXCreateContext. Is it a different one?

Tank · « **Reply #73 on:** October 06, 2009, 06:21:13 pm »

Nope, it's the same. "X_GLXCreateContext" is the minor code. Maybe the given context (myContext) is just invalid. But this is normally detected by evaluating return values, before (what you do in the source, of course).

Hey Laurent!

By now I'm using Ubuntu instead of Windows Vista. But I've problems with the new OS.
When I downloaded the SFML2 of the SVN repository I compiled it without any problems. Then I wrote a very short application and compiled it without problems, too. But when I wanted to run it, these errors came in my terminal:

Code: [Select]


X Error of failed request:  GLXBadContext
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Serial number of failed request:  30
  Current serial number in output stream:  33

I found out, that is so because my graphic card. I run this command in the terminal and found out, that this is my card:
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01)
Tank said me, that there are problems with ATI and the newest SFML2. Please, can you correct this error? It's so boring without developing with SFML2! :wink:
Thank you in advance!
Paul
