Title: Cannot get template project to run in Xcode
Post by: tylermfdurden on September 11, 2013, 05:53:16 am

In Xcode 4.3.3, on OSX 10.7.5, I am creating a new SFML app, with C++11 and Clang.

If I run it as is, I get linker errors:

Undefined symbols for architecture x86_64:
  "_objc_msgSend", referenced from:
      resourcePath() in ResourcePath.o
  "_NSLog", referenced from:
      resourcePath() in ResourcePath.o
  "_OBJC_CLASS_$_NSAutoreleasePool", referenced from:
      objc-class-ref in ResourcePath.o
  "_objc_msgSend_fixup", referenced from:
      l_objc_msgSend_fixup_alloc in ResourcePath.o
  "_OBJC_CLASS_$_NSBundle", referenced from:
      objc-class-ref in ResourcePath.o
  "___CFConstantStringClassReference", referenced from:
      CFString in ResourcePath.o
ld: symbol(s) not found for architecture x86_64
 

So I add the Foundation.framework to the build, and it builds with no errors.
However it crashes on start with a dyld_fatal_error.
The console log is:

dyld: Symbol not found: _OBJC_CLASS_$_NSObject
  Referenced from: /Users/... .../Frameworks/sfml-window.framework/Versions/2.1.0/sfml-window
  Expected in: /usr/lib/libobjc.A.dylib
 in /Users/... .../Frameworks/sfml-window.framework/Versions/2.1.0/sfml-window

This is with SFML 2.1
I've tried fixing the working directoy in the scheme, ensured build target is 10.7, commented out all of main, tried adding CoreFoundation...

I didn't test older version of Xcode. Try upgrading to 4.6. It's available for OS X 10.7 too.

I updated and tried again... Same problem.
No matter what the build target or what frameworks I add, I get the same fail on start.
Here is the assembly:

I never had this error personally so I don't really know where to start.. Here are some things you can try :

 - install / update the Command Line Tools (from Xcode preference panel, in the download section).
 - create a new SFML project

Let me know if you find anything.
