[Wxlua-users] wxLua works as module, require"wx"

[John L. <jla...@gm...>]

In the wxLua/apps/luamodule dir is code to make lua require"wx" work in Lin=
ux.

You create the wx.so library by running $make in the
wxLua/apps/luamodule/src dir and all of wxLua will be created for you.
The output wx.so lib is just dumped in the src dir for now.  The
Makefile uses the wx-config script and therefore it MUST be in your
path. Additionally it puts the resultant wxLua libs it creates in the
appropriate lib dir of wxWidgets so it must be writeable. As a
developer I never bother to install wxWidgets, but if you have you'll
have to hack the Makefiles located in each XXX/src dir to output them
elsewhere. The Makefiles are fairly straightforward so this shouldn't
be difficult. Eventually we'll get the bakefile's configure to work
with this new project.

A sample program called luamodule.wx.lua in that dir shows it working
by simply creating a wxFrame. Test it from the
wxLua/apps/luamodule/src dir using
$../../../bin/lua luamodule.wx.lua

ps. Francesco can you rebake the files. I have added back the
-DWXLUA_CODE define, now called WXLUA_LUA_NEWTHREAD for clarity in
modules/build/bakefiles/modules.bkl. We had to remove that previously,
but now I see that it's required for using wxLua as a module.

Also, about adding this to bakefile? Note: The output must
unfortunately be called wx.so since otherwise require"wx" will fail.

I don't really understand completely what I've done, but it seems to
work. See apps/luamodule/src/Makefile and the wx.so: tag. I guess I'm
compiling the luamodule.cpp file, linking it with all the other libs,
and then creating a .so library using -shared. I think also that -fpic
is needed.

I haven't the foggiest idea about how to do the same in MSW, I guess
it should be a DLL? But then how do you "link" this DLL to all of the
wxLua and wxWidgets DLLs or can you create the wxLua and wxWidgets
libs as libs and link them to the DLL?

Maybe someone who uses lua's require more regularly can shed some light on =
this?

ps. I've also posted this on <lu...@ba...> to see if
anyone there can clarify how to deal with this in MSW.

 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 is 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 ?

 again thank you for your great work on bringing us wxLua !!!!

yes, sure

Done...

I have a little mess currently with wxWidgets as I have various 
installed versions and all patched so it will take me a bit before being 
able to test the bakefiles for luamodule but I've already written the 
necessary stuff ;)

yes but this is a dynamic link (wx.so is only 150K on my system)

yes, -fpic is for generating code for shared objects (pic = position 
independent code)...

yes, I think so.

using the import libraries generated when creating the DLL (i.e. when 
you compile with SHARED=1 both .lib and .dll files are created - the 
.lib are import libraries).

if I got it right then: no it's not possible.
code compiled in "DLL" mode is different from code compiled for static 
linking.
