[gecode-users] version 3.2: problem compiling examples in Xcode

[Guido Tack]

Hi Serge,

apparently Apple has changed the libstdc++ in Snow Leopard.  I've  
built a new package, linked against the 10.5 SDK.  It's available here:

http://www.ps.uni-sb.de/~tack/Gecode-3.2.0.dmg

I would be grateful if you could test it and let me know if it works  
for you!  If it does work, I'll put it up on our download page.

Mauricio: It's strange that the binary framework works for you on  
10.5.8.  Could you please let me know which version of libstdc++ you  
have (i.e., the ? in /usr/lib/libstdc++.6.0.?.dylib)?

Cheers,
	Guido
