Hi All I am compling my application using gcc 4.2.3 and using AIX ld for linker. I get the following link warning: ld: 0711-224 WARNING: Duplicate symbol: .non-virtual thunk to HandlerBase::resetErrors() There several of these warnings. However, I am not able to understand what is a "thunk" and would appreciate if you can point me on how to fix this issue. I am not able to GNU ld due different link issues. Thanks in advance With Regards Vardhan
