PortingManager is a free tool that provides assistance when porting C and C++ Solaris applications to zSeries Linux. PortingManager scans a source code tree, looks for Solaris APIs, flags them, and provides documentation that is useful when porting the API from a Solaris-specific function call to an equivalent Linux function call.
I just wish they had something like that for when I was porting some AIX apps to Solaris. And it would be nice if they took into account (crappy) compiler issues as well.
But, then I guess I wouldn’t have had so much to do at work.
