hi and please forgive the extreme newbieness, but as I’ve been unable to  
locate this error reported anywhere, I’d like to ask for your advice.

when issuing “make cocoa” under osx lion (with XCode4 installed) I get the  
following errors:

cocoa\_window.m:574: error: ‘NSOpenGLPFAOpenGLProfile’ undeclared (first use  
in this function)  
cocoa\_window.m:574: error: (Each undeclared identifier is reported only once  
cocoa\_window.m:574: error: for each function it appears in.)  
cocoa\_window.m:574: error: ‘NSOpenGLProfileVersion3\_2Core’ undeclared  
(first use in this function)

Any idea on what might be wrong?  
Thank you for you attention

Got it working with the help of a friend,

Frist, I had to update Xcode 4.1 to Xcode 4.3.2. Then, I had to install the  
Command Line Tools using Xcode preferences. After that I was able to  
compile through the command line.
