I am using an ILP system named proGol which is not anymore state of the art; progol implementation has been in C though the syntax of coding is similar to prolog. However, I can run it on old machines with gcc version of 3.4.3. Such machines are very old and I need to run my code on new servers with gcc version on 4.6.3. When I do that, the software outputs segmentation error. I believe the problem is the gcc versions that are not compatible and progol itself probably can be run only on 32 bit processors. Does anyone know how I can adjust the gcc version of machine to older versions?
