But does it work or does it lead to the same errors when starting any of the
GUI applications that come with the libraries?
Sadly it may not be the end your troubles: the `const NSNotificationName
NSPreferredScrollerStyleDidChangeNotification` message was added in 10.7.
But that doesn't mean you're out of options. On 10.6 you can still use code
injection without any of the recent restrictions. That notification was added
in a later OS version, so on 10.6 it will never be sent. "All" you'd thus need
to accomplish is to preload a shared library that provides a definition for the
symbol. Its actual value is a moot point because the symbol simply won't be
So a library built from a simple sourcefile containing
const NSNotificationName NSPreferredScrollerStyleDidChangeNotification;
const void* returnAddressOfMissingSymbols(int i)
retval = (void*)
retval = NULL;
The function is there to force the linker not to optimise the global variable
away, and is designed for easy addition of similar missing symbols.
I'll try to remember adding this to a pet project I once started:
