glfwInit failing error
Post: #1
So, I've had this error for a while and I had found a similar thread with a similar problem.
[Session started at 2008-08-23 11:15:36 -0400.]
glfwInit failing because you aren't linked to OpenGL
FAILED OPENING WINDOW
O3D has exited with status 1.
However after reading the thread I added a resource folder and I still got the same problem on OSX tiger.
Heres the code:
Any help would help.
ps Don't suggest sdl or glut, I have my reasons.
pss I didn't post in that thread as most forums don't like reviving old threads.

}Any help would help.

Assuming this means what it says, try adding OpenGL.framework to your project.

I wrote this code, and I don't see how it can fail if you're linked to OpenGL, and I've never met anyone else with the issue. I have to assume that (despite appearances) you are not linked to OpenGL. Please post the detailed build log from Xcode to confirm that you are indeed managing to link to the OpenGL framework.
The current implementation of GLFW for Mac OS X is Carbon. I'd avoid it. I can't think of any good reason to use GLFW over SDL other than deployed binary size.

Nothing but build succeeded.
I won't use sdl as I can't use argc and argv.
The file size also has an impact for the systems I am developing for.

I fixed the problem by putting the framework includes in the prefix header.
Now it's making the window from a nib and returns 48 if I delete it.

There's no way that could have any effect.

What do you mean?

It makes the window from a main.nib for some reason.
Then, if I delete the nib, it returns a strange error code of 48.
How do I disable using a nib in xcode 2.4, google keeps giving stuff for 3.0
edit:Actually if you could supply a sample xcode 2.4 project, that would help me figure out what I'm doing wrong.

Okay its obvious that my mac hates me, so if possible could someone tell me where I can find a sample xcode 2.4 project, as google is being surprisingly mute.

/Developer/Examples is full of 'em... just not for GLFW. For GLFW, I'd start with an empty project, add a "Carbon Application" target, the GLFW library and header, the OpenGL and Carbon frameworks.

AGL is probably also required.
Your picture link is broken (needs to be a link, not an inline image, with imageshack).
Cmd-shift-3 is an easier way to take screenshots than some random 3rd-party software
I can't tell anything much at all from the screenshot, but if your app compiles and links, chances are it's a bug in your program.
