now I understood: wxLua bindings are double-"protected" by both 
wxUSE_XXX symbols and wxLUA_USE_XXX ones.

That's good. However I must say that wxbind.h uses very few wxUSE_XXX 
symbols (I understand it's a real trouble to write all those #if/#endif 
by hand - BTW is wxbind.h auto generated ?).

For example, I haven't got the STC headers installed and my compilation 
stops with the error:

./../modules/wxbind/include/wxbind.h:579:24: error: wx/stc/stc.h: No 
such file or directory

Unfortunately there is no wxUSE_STC symbols... this is because STC is a 
contrib.

I think we should separe wxlua contrib wrappers from wxlua wxwidgets 
wrappers and then create a BUILD_CONTRIB_WRAPPERS=0/1 (or something like 
that :)) option to bakefiles.

I've found that wxUSE_WAVE is deprecated since wx2.5.1 in favour of 
wxUSE_SOUND.
I also searched all my local wxLua directory for 
wxLUA_USE_wxCriticalSectionLocker and I couldn't found any definition of 
it (I think it should be in wxluasetup.h but it's not). I could just 
found places where it was used (#if wxLUA_USE_wxCriticalSectionLocker...)

should we add it to wxluasetup.h ?

Also, I think we need to write in some doc a list of files which are 
automatically generated. I really have a vague idea about what's auto 
generated and what not :(


In conclusion, since last update, I could build completely wxLua 
*libraries* just changing

#define wxLUA_USE_wxStyledTextCtrl              1

to

#define wxLUA_USE_wxStyledTextCtrl              0

However I still get undefined reference to:

/wxlua/src/wxlstate.cpp:1740: undefined reference to `s_wxluatag_wxWindow'
./wxlua/src/internal.cpp:1049: undefined reference to 
`s_wxluatag_wxEvtHandler'
./wxlua/src/internal.cpp:1176: undefined reference to `s_wxluatag_wxBitmap'

I'm still looking to these because now I can see that these symbols are 
defined and compiled.
Probably I need to play with library order.
As soon as I solve this, I'll commit my bakefile changes.
