OpenGL issue

[mickeoliver]

Hi,

I've been trying to use this tutorial (http://openglbook.com/the-book/chapter-1-getting-started/) to learn some opengl.

I got it to compile without much problem, but when I try to run it this error is displayed:


X Error of failed request: BadAlloc (insufficient resources for operation)
Major opcode of failed request: 136 (GLX)
Minor opcode of failed request: 34 ()
Serial number of failed request: 38
Current serial number in output stream: 39

I've spent a couple of hours googling this but I couldn't find a solution.

Does anyone know how to fix this? Thank you.

Maybe you're using malloc/calloc/realloc in a way that it grows very fast and takes all the memory up? It is a common error while doing this and it can cause a program to crash. But since it's OpenGL, the error might be something else (I'm not really familiar with it). But you can post the code and we'll see.

Here's the code:


#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <GL/glew.h>
#include <GL/freeglut.h>
#define WINDOW_TITLE_PREFIX "Chapter 1"

int CurrentWidth = 800,
CurrentHeight = 600,
WindowHandle = 0;

void Initialize(int, char*[]);
void InitWindow(int, char*[]);
void ResizeFunction(int, int);
void RenderFunction(void);

int main(int argc, char* argv[])
{
Initialize(argc, argv);

glutMainLoop();

exit(EXIT_SUCCESS);
}

void Initialize(int argc, char* argv[])
{
InitWindow(argc, argv);

fprintf(
stdout,
"INFO: OpenGL Version: %s\n",
glGetString(GL_VERSION)
);

glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
}

void InitWindow(int argc, char* argv[])
{
glutInit(&argc, argv);

glutInitContextVersion(4, 0);
glutInitContextFlags(GLUT_FORWARD_COMPATIBLE);
glutInitContextProfile(GLUT_CORE_PROFILE);

glutSetOption(
GLUT_ACTION_ON_WINDOW_CLOSE,
GLUT_ACTION_GLUTMAINLOOP_RETURNS
);

glutInitWindowSize(CurrentWidth, CurrentHeight);

glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);

WindowHandle = glutCreateWindow(WINDOW_TITLE_PREFIX);

if(WindowHandle < 1) {
fprintf(
stderr,
"ERROR: Could not create a new rendering window.\n"
);
exit(EXIT_FAILURE);
}

glutReshapeFunc(ResizeFunction);
glutDisplayFunc(RenderFunction);
}

void ResizeFunction(int Width, int Height)
{
CurrentWidth = Width;
CurrentHeight = Height;
glViewport(0, 0, CurrentWidth, CurrentHeight);
}

void RenderFunction(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glutSwapBuffers();
glutPostRedisplay();
}


I've only really programmed in c++ before, but I did this in C because the tutorial was in C too. I might have forgotten something because of that ;)

I don't think you googled enough.

This is the exact same problem, same tutorial, same example, same error, (hopefully the same fix).

Took me 2 minutes.

Thanks, but if you actually read the post I think that he makes it pretty clear that those fixes did not help. And it seems like there is still no fix.

I'm pretty sure that's the fix. I don't think there are any others.

[mickeoliver]

Well then that's a bummer because it didn't work for me either.

[mickeoliver]

I found the solution, I'll post it here for anyone who might have the same problem: my NVIDIA driver seemed to have some issues with opengl 4.0, so I just changed the version in the code to 3.3. Worked perfectly.

[t1497f35]

Nvidia released recently the 275 driver series, which fixes important OpenGL 4.x issues (http://g-truc.net/post-0402.html#menu) which might also solve your issue if you wanna use GL 4.x.

[mickeoliver]

Thanks, I'll give that a try!

Thanks I had the same issue and changing to 3.3 worked. http://developer.nvidia.com/opengl-driver indicates my card doesn't support OpenGL 4.
