[Biococoa-dev] string definitions

[Koen van der Drift]

Hi,

I was adding the stringdefinitions to some more source files, and ran  
into a weird build error. I can add #import "BCStringDefinitions.h" to  
one file (BCSymbol.m in this case), and use the replacement properties  
for various strings. However, if I then add #import  
"BCStringDefinitions.h" to the next file (BCAminoAcid.m), I get linker  
errors such as:

ld: multiple definitions of symbol _BCSymbolpKaProperty
/Users/koen/Documents/Development/Active  
Projects/FrameWorks/BioCocoa/build/BioCocoa.build/BioCocoa.build/ 
Objects-normal/ppc/BCAminoAcid.o definition of _BCSymbolpKaProperty in  
section (__DATA,__const)
/Users/koen/Documents/Development/Active  
Projects/FrameWorks/BioCocoa/build/BioCocoa.build/BioCocoa.build/ 
Objects-normal/ppc/BCSymbol.o definition of _BCSymbolpKaProperty in  
section (__DATA,__const)
ld: warning prebinding disabled because dependent library:  
/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/Frameworks/ 
AppKit.framework/Versions/C/AppKit can't be searched


Anyone has more knowledge about linkers, and hopefully how to fix this?  
The file  
/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/Frameworks/ 
AppKit.framework/Versions/C/AppKit is present on my system.

thanks,

- Koen.
