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

Wed Nov 4 16:13:51 CET 2009

Hello Serge,

glad to hear it works now.  We're currently preparing the release of  
3.2.1 anyway (which includes a number of bug fixes), so I just  
replaced the 3.2.0 package for the time being.  Thanks again for  
pointing this out!

Cheers,
	Guido
