This has been tried using GDB 7.5 on Gentoo GNU/Linux as well as GDB 7.5 on MacOS X (installed via Homebrew) with the same result. Here is the result when running the example from the documentation: (gdb) python >import gdb >class Greet(gdb.Function): > def __init__(self): > super(Greet, self).__init__('greet') > > def invoke(self, name): > return 'Hello %s' % name.string() > >Greet () >end (gdb) greet test Undefined command: "greet". Try "help". (gdb) greet Undefined command: "greet". Try "help". gdb.Command and gdb.Parameter both work as expected in the two GDB installations that I tried gdb.Function in.
