I am trying to build a program that compiles fine in ubuntu on osx lion. The  
linker complains as such:

```

I have included the new glfw.h I saw in a previous post here but still no  
luck. I have also tried to tell cmake

```
SET(EXTRA_LIBS "-framework Cocoa -framework OpenGL")

```

But still the same linker erros.

Any ideas? 🙂

I found the solution:

For those not using cmake you must use -F or -framework to link
