Hi i made a command line tool but when compiling i get this error :

which is rather strange because the file is in the right folder in the project :

I already tried removing it and then adding it again , but it didn’t help.
Did i forget to include something etc … ?
I’m not really familiar with xcode so any help would be greatly appreciated.
You don’t need the GL folder.
Within OpenGL.framework is gl.h, glext.h, and whatnot, and it’s adapted for mac.
If you insist on GL/gl.h, you need to add it to the project’s header search path. To do this, go to your project’s settings->build rules, and search “Include Paths”. When you find the “Header Include Paths” section, type in “${SRCROOT}/”. This assumes that GL/gl.h is in the same project as your folder.
