Xcode takes forever to compile!

Well what are you compiling? how much code is there, did you do a clean before building? right now some more information is needed.

 

You are probably including a header file which #includes another header file, but this other header file #includes the first one. This is a big no-no!

So the compiler gets stuck in an infinite loop and its stack grows rapidly and soon eats up all ram and hogs the machine's resources making it harder to kill Xcode the longer you leave it. The best solution is to fix these inter-dependencies.


There is another way though if you can't find the problem. Objective-C avoids this problem with the #import directive. You can get the same effect in C if you gate all your (#included) headers with something like:

Code:

#if !defined _HEADERNAME_H
#define _HEADERNAME_H

...

#endif // _HEADERNAME_H

(note <HEADERNAME> must of course be unique for each header)
