Well, when I serialize a Lua State with Luabind classes inside, the following happens:

When I come to the point to serialize the Lua Class Pluto first serializes the name of the class which function properly. At next he wants to store some Userdata, no problem. But then he continues storing the lua table (which represents the lua class, I think), and there he wants to store a function called __eq (the first element he wants to store in the table). I get an error in Pluto, because this function seems to be a C/C++ function from luabind.

I don't know how to solve that problem. Any ideas?

That's very interesting. While I've barely ever used luabind, on the
face of it it doesn't seem like Lua tables created by luabind should
be any different than Lua tables created by the Lua API. Would you
mind providing info on how the table was created, and what happened
when you tried to serialize it with Pluto?

I'm using Lua and Luabind for a game development project and therefore I
must be able to serialize the actual "lua world" in my savegame to later
load it and resume at the same position in game as I saved.

I tried to use the Pluto Library, because it should excactly do what I
needed. This library seems to work perfecly, but it has a major missing
feature or problem. The tables luabind creates for storing the lua
classes can't be serialized by pluto. So I cannot save lua instances of
lua classes ( and also instances of c++ classes, but that's another

So here is my question: Does anyone of you ever tried to serialize a lua
states in combination with luabind? Did you get Pluto working or did you
use another library?

I hope you can help me!
