 Posted: Tue Jan 10, 2006 2:41 pm Post subject: [SOLVED] GLFW X_SetInputFocus crash |
 |
|
Hi, I'm not sure this should go in this part of the forum, but I'll give it a shot.
I'm currently programming GLSL, and using glfw to do the drawing and handling of windows. The problem is that when I try to start the program (after succesfully compiling it) it always crashes with this message:
| Code: | X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 42 (X_SetInputFocus)
Serial number of failed request: 25
Current serial number in output stream: 28 |
The message is probably related to glfw, and I've found a reported bug regarding the problem in bugzilla. But it was reported 2 years ago! Has anybody seen this problem before, and more importantly, does anybody have a clue what's going on?
The program succesfully started a couple of times yesterday (crashing most of the time), so the problem seems a bit random. Today it won't start at all.
Even with the most minimum glfw-code, the program won't start.
I compile it using:
| Code: | | -L/usr/X11R6/lib -L/usr/local/lib -lX11 -lGLU -lGL -lglfw -lpthread -lXxf86vm |
and gdb jsut outputs the same error. The "list" command just shows the first part of the main function.
My emerge --info shows (with some info removed):

I really don't want to have to switch to GLUT/SDL/OpenGLUT/FreeGLUT or any other.. It just feels like a dead end right now. I'm doing this for a school project, and the deadline is closing in on me...
I hate when things work in windows and not linux. I want to be able to develop things for _my_ operating system, not the operating system that my university uses (mainly windows).

I finally solved the problem. One needs to insert a sleep() after glfwInit().
glfw asks X for a window, the problem is that it then continues drawing in the canvas without checking if it has received a canvas. Simply solve it by waiting for the canvas, and then carry on.
