Humm, that's strange.

this is great news !!!!
our pipeline is strongly based on lua and I can`t wait to put more wxLua in
action !!

this worked great , compile and run .
but if I try
lua luamodule.wx.lua
I get an error of type :
libwx_gtk2_wxlua-2.6.so: undefined symbol: wxLua_lua_getnewthreadhandler
we have the standard lua 5.1 distribution installed , what is exactly the
difference beetwen lua 5.1
and lua include the wxLua distribution ?
is it only the function enable by the WXLUA_LUA_NEWTHREAD flag ?
We added some functions in lstate.c to track when a coroutine is
created, there's really nothing to them. This is unfortunately tricky
to "fix". In wxLua itself we want to have WXLUA_LUA_NEWTHREAD defined
so that coroutines will work, but for the luamodule we can't have it
defined for people who want to use a stock lua executable which means
that module/wxlua has to be compiled without it.
1) We could add a compiler option or new #define to NOT define
WXLUA_LUA_NEWTHREAD for people who want to use the module. Sounds
strange, but I think it should be on by default, hence the added
define undoes the default define.
2) Use the lua registry? Does it get copied for coroutine created
lua_States? If so then we don't need this hook at all. I had tried to
stick the wxLuaStateData into lua itself as a global variable, but
somehow it wasn't in the coroutine state, though other bits were.
The bottom line is that we need to associate each lua_State with our
wxLuaStateRefData and so things break if lua_States get created behind
our back as they do for coroutines.
For now, just edit the top of wxLua/modules/wxlua/src/wxlstate.cpp and
add this to undef it and that way it won't get compiled in.
#ifdef WXLUA_LUA_NEWTHREAD
#undef WXLUA_LUA_NEWTHREAD
#endif
again thank you for your great work on bringing us wxLua !!!!
You're welcome, it's a work in progress...
