Re: problems with a .so using dlsym()

[Mihnea Balta <dark_lkml at mymail dot ro>]

Those are C++ mangled names. In order to obtain them through dlopen() with 
their sourcecode names, you have to declare them as extern "C", i.e. :

extern "C"{
	void copyFromTemplate();
};
[...]
void copyFromTemplate(){
 [...]
}

This way the name won't be decorated in C++ manner (but you can't use 
overloading and other stuff either).

If you want to export classes from your plugin, it's a bit more complicated, 
since you need to use factories.
