Hi,  
I’m currently using GLFW as a base to build an engine on-top of.  
I have run into an issue when building on OSX Lion (Latest version and  
updates) when trying to run in fullscreen.  
The error is :  
2012-05-04 00:05:22.449 main invalid pixel format attribute  
2012-05-04 00:05:22.451 main NSMapGet: map table argument is NULL

Anyone else got this ? Workarounds available ? or a fix in the works ?

Thanks in advance.

Which version of GLFW are you using?

Does fullscreen work despite the error? If not, what happens instead?

I’m not the OP, but I’m getting the same error when using OpenGL 3.2 and  
fullscreen doesn’t work.

This was a bug in GLFW. It has been fixed in 2.7.6, which will be coming out  
shortly.

Hey,  
I noticed that this was mentioned as fixed in 2.7.6 however I still seem to be  
experiencing the same issue still.

With even the simplest of code :

```
#include <iostream>
#include <GL/glfw.h>
int main()
{
	glfwInit();
	glfwOpenWindowHint( GLFW_FSAA_SAMPLES, 4 );
	glfwOpenWindowHint( GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE );
	glfwOpenWindowHint( GLFW_OPENGL_VERSION_MAJOR, 3 );
	glfwOpenWindowHint( GLFW_OPENGL_VERSION_MINOR, 2 );
	glfwOpenWindowHint( GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE );
	glfwOpenWindow( 1280, 800, 24, 24, 24, 24, 8, 0, /*GLFW_WINDOW*/GLFW_FULLSCREEN );
	glfwSetWindowTitle( "Prototype-001" );
	printf("OpenGL Version : %s", glGetString(GL_VERSION));
	bool running = true;
	while( running )
	{
		glClear( GL_COLOR_BUFFER_BIT );
		glfwSwapBuffers();
		// Check if ESC key was pressed or window was closed
		running = !glfwGetKey( GLFW_KEY_ESC ) &&
		glfwGetWindowParam( GLFW_OPENED );
	}
	return 0;
}

```

It creates the same error :

```
2012-07-13 13:19:54.873 main[17320:707] invalid pixel format attribute
2012-07-13 13:19:54.874 main[17320:707] NSMapGet: map table argument is NULL
```

Ahha, Disregard the previous post, I seem unable to delete it.  
I believed I was running 2.6.7 however when printing the version out with :

```
glfwGetVersion( &majVer, &minVer, &revVer );
	printf("Using GLFW Version : %i.%i.%i", majVer, minVer, revVer);

```

It showed it wasn’t actually using the latest version.

I removed and reinstalled the files into /usr/local/… and it is now working  
🙂

Thanks

You had me worried there for a moment. Glad it works now 🙂
