They all compiled OK. I only got one warning when I compiled gate: Linking Gate ... /usr/bin/ld: warning: libstdc++.so.5, needed by /beo5/newGate/SL3/ROOT/root_v5.14/lib/libCore.so, may conflict with libstdc++.so.6 ... Done! And when I run Gate, it give me error like following, could anyone give me some sugestion?
