error compiling GUI - string constants

[Riccardo Mottola]

Hi,

while compiling GUI, I get these errors abount string constants.

 Compiling file externs.m ...
externs.m:270:1: error: initializer element is not constant
 NSString *const NSStringPboardType = NSPasteboardTypeString;
 ^
externs.m:273:1: error: initializer element is not constant
 NSString *const NSColorPboardType = NSPasteboardTypeColor;
 ^
externs.m:276:1: error: initializer element is not constant
 NSString *const NSFontPboardType = NSPasteboardTypeFont;
 ^
externs.m:279:1: error: initializer element is not constant
 NSString *const NSRulerPboardType = NSPasteboardTypeRuler;
 ^
externs.m:282:1: error: initializer element is not constant
 NSString *const NSTabularTextPboardType = NSPasteboardTypeTabularText;

<...>


What is the issue? I see the definition here:
Headers/AppKit/NSPasteboard.h:APPKIT_EXPORT NSString *const 
NSPasteboardTypeString;
Source/externs.m:NSString *const NSPasteboardTypeString = 
@"NSStringPboardType";

and it is declared as *const.

NSString *const is not "constant" to initialize a definition (I tried 
"const NSString *const" too but it doesn't work: constant string to a 
constant pointer)

The only working way I found is not to use the previous string 
delcaration in the next one, e.g.:

NSString *const NSPasteboardTypeString = @"NSStringPboardType";
NSString *const NSStringPboardType = @"NSStringPboardType";

instead of
NSString *const NSStringPboardType = NSPasteboardTypeString;

thins fixes my compilation issue, but I am hesitating to commit this 
since it looks "stupid" to me

What is GCC doing here or what I am overlooking?
