I compile a program on host A (Linux, i386) with g++-3.1.1. I copy it to machine B and attempt to execute it and get the following message: makebar: /usr/local/lib/libstdc++.so.4: no version information available required by makebar) I recompile the same program on host B (Linux, i386) with g++-3.1.1 and it works fine. What is happening, please? Thanks. Tom Browder
