Hi to all.
I can’t link this dummy program involving STL exceptions.
The linker reports the sequent message:
"Error: undefined reference to ‘exception::_Doraise(void) const’ "
Notice that if I define the function void _Doraise(void) for the 2 classes
MyExceptionType1 and MyExceptionType2, it seems to work: how can I avoid
this?
Thanks in advance,
Gianluca
