[webkit-dev] Webkit can only be built on Tiger?

[Robin (Yibin) Lu]

I am using Mac OS X 10.3.9. When I was building the webkit, I got an error:

I found that +stringWithCString:encoding only available in Mac OS X
10.4 (http://developer.apple.com/documentation/Cocoa/Reference/Foundation/ObjC_classic/Classes/NSString.html#//apple_ref/doc/uid/20000154-BAJCCGHJ).
Does that mean that I can only use Tiger to build WebKit?

Thanks!
