Okay, I'm officially a fool now. The problem was I'd defined a constructor RootClass::RootClass(void) as well as the 'real' constructor, but in my code I'd forgotten to implement RootClass(void), instead seeing the 'real' constructor and not realising I was missing one :-(
So of course when I came to construct a subclass the code compiled okay because the (void) constructor was declared in the .h file, but the linker couldn't find the symbol because the function wasn't actually there... Thanks for your help guys, it did help me track down this rather obvious problem, so sorry about it being something so simple! Also Paul, in reference to your earlier comment: > The '_ZN8RootClassC2Ev' is not a valid mangled symbol at all; That's my fault too - I didn't realise how name mangling worked, and I changed the name of the class to match the description I'd given earlier (my *intention* was to avoid confusion - ha!) The actual name of the real class is only eight characters long, so the symbol was originally correct until I mangled it a bit too much ;-) Sorry about that! Anyway, thanks again for your help, my code now compiles correctly! Cheers, Adam. _______________________________________________ Help-gplusplus mailing list Help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
