[gecode-users] Problem linking Gecode 2.0.1 libreries

[Raffaele Cipriano]

Dear GECODE developers and users,
I have sucessfully installed GECODE 2.0.1 on my PC (cygwin on Windows XP 
32bit), and I'm trying to compile an example, the queens.cc file...
I have some problems linking the libraries (compiling the file is ok).
I've also installed GECODE 2.0.1 on a cluster x86_64  with Linux CentOS 
v.4.3 and  2.6.9-34.ELsmp CentOS Kernel, and I get the same problem.

 I get this message

I'm sure that the libraries are correctly referred (if I don't use one 
or more  -l<library> option I get a lot of undefined references)..
It seems there's some trouble with the class Options or SizeOptions and 
with the distinct contraint (line 80 is  distinct(this, q, opt.icl());  )


Could you help me?

Thank you
