[gecode-users] g++ v4.2 dependency

[Guido Tack]

Hi Martin,

there were bugs in gcc 4.1 that resulted in incorrect code, especially the set constraints were affected by this.  You can of course simply change the check in configure.ac, but I can't guarantee that the resulting code works.  You could run the tests and see if they fail (I think they just used to go into an infinite loop somewhere for the sets).

I haven't built with gcc 4.1 for a long time so I'm not even sure it compiles any longer.

Alternatively, perhaps you can build a fully statically linked version on a newer system.

Cheers,
Guido
