Re: [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

Dear GECODE developers and users,

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).

v.4.3 and  2.6.9-34.ELsmp CentOS Kernel, and I get the same problem.

I get this message

Build complete for project QueensGecode2

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)..



Could you help me?

Thank you
