Alrighty. I'm trying to update my MUD to c++, but have run into a bit of trouble... namely:

Quote:
Sat Sep 2 18:47:20 2006 :: [*****] BUG: Error locating do_say in symbol table. ../bin/swr: undefined symbol: do_say
Sat Sep 2 18:47:20 2006 :: [*****] BUG: Fread_command: Function do_say not found for '

I know this is because I updated the MUD from C to C++, something dlopen and whatnot don't like. I'm operating Fedora Core 5, and the MUD is SWFOTEFUSS. So... comments on how to solve this situation? I appreciate it, thanks.

Using FUSS right? Make sure you have the right Makefile flags toggled.

I suspect this is a name-mangling problem. I converted to C++ ok, but not with dynamic linking.

C++ mangles names so that it can build in the function argument types into each name (as you can have identically-named functions with different argument lists).

Thus the problem is probably either:

You are looking for a mangled name, but the dynamic library has them un-mangled; or
You are looking for an un-mangled name, but the dynamic library has them mangled
