[gecode-users] Problem linking Gecode 2.0.1 libreries

[Guido Tack]

You seem to compile a 2.0.1 queens against a 1.3.1 gecode.  That will  
certainly fail.  Also, could you please quote the compiler version  
you're using, for gcc it makes a difference whether 3.x or 4.x is  
used, as the latter supports symbol visibility annotations.

Cheers,
	Guido
