Pipers, We've tried compiling Piper and Overflow with GCC 2.96, the most recent GNU compiler. Unfortunately, we've encountered a number of problems that cannot be fixed at the moment. GCC 2.96 is an "experimental" compiler that (1) has some bugs and (2) is not fully ANSI C++ compatible. It is also the standard compiler for some Linux distributions. When it reaches 3.0, we believe that we will be able to once again compile with it, but, in the meantime, GCC 2.95 should continue to work. If anyone has successfully compiled Piper/Overflow with another compiler, please let us know. Cheers. Jeff -- J.W.
