Stratagus doesn't build for lua 5.2. I have created a patch.

Patch not applied (too many #ifdef)

Since getglobal is supported with previous version, I use it instead of "gettable(GLOBAL_INDEX)"
Add an inline function for the renaming of objlen/rawlen (I use the 5.2 syntax in the code).

The code is shorter with the new syntax :-)

Note that I didn't see any version of ToLua++ that is compatible with Lua 5.2

The patch don't fixes anything still getting:
/usr/bin/tolua++: symbol lookup error: /usr/bin/tolua++: undefined symbol: luaL_newstate
make[2]: *** [tolua.cpp] Fehler 127

This patch was to fix the stratagus part.
The problem is as mentioned above that tolua++ doesn't support lua5.2 .
I've Partly fixed tolua++ (except the script part ). I've contacted the developer for help, but I didn't get a reply, i think from the current developers side i have the feeling the project is dead.

I think if it's possible it would be better to use tolua in stead of tolua++.
As tolua supports lua 5.2.

As an addition to the latest post. If someone wants to help we can also port tolua++ to lua 5.2.
