CGContextCopyPath function missing in Leopard

[Riccardo Mottola]

Hi,

I am trying to port ArcticFox to 10.5 Leopard.

I get this error:

52:30.98 /Users/multix/code/Arctic-Fox/gfx/2d/PathCG.cpp:313:21: 
error: use of undeclared identifier 'CGContextCopyPath'; did you mean 
'CGContextClosePath'?
52:30.98   CGPathRef sPath = CGContextCopyPath(cg);


However, according to documentation, this function should exist since 
10.2, it is very old!:
https://developer.apple.com/documentation/coregraphics/1455397-cgcontextcopypath?language=objc

I tried to look, I find it inside the libary:

Binary file 
ApplicationServices.framework/Versions/Current/Frameworks/CoreGraphics.framework/Versions/Current/CoreGraphics 
matches


but not in the headers!

Any of you has seen something like that? Could this be an error in my 
headers, the library being missing?

I tried some googling, but didn't find anything.

Thanks,
Riccardo
