The Lua src in wxLua/modules/lua/src is the source from the Lua 5.1.4 tar.gz.

This is what I use for wxWidgets, for better or for worse.
../configure \
--prefix=/home/john/wx/wxWidgets/wxWidgets-2.8.10/config_gtk2ud \
--enable-optimise=no \
--enable-debug=yes \
--enable-debug_gdb=yes \
--enable-mem_tracing=no \
--enable-profile=no \
--with-dmalloc=no \
--enable-prologio=no \
--enable-gtk2=yes \
--enable-unicode=yes \
--with-gnomeprint \
--enable-mediactrl=yes \
--with-opengl \
--enable-graphics_ctx \
--with-sdl

This should handle creating the monolithic wx.so module regardless of
the other settings, I think.
configure --enable-monolithic-luamodule

I'll have to look into how "monolithic" we can actually make it. You
absolutely have to link to the Lua shared lib, but it might be
possible to compile wxWidgets statically to allow the wxLua module to
incorporate the wxWidgets libraries. If you compile wxWidgets as a
shared lib, then no, it cannot be incorporated into wx.so and will be
a dependence.
I did find a bug in the configure generated modules/Makefile.
Look for these statements and notice that I removed the $(WXLUA_LIBS)
from it. The real fix goes into the Bakefiles, but I have to verify
that it's Ok to do that for the MSW builds.
../lib/$(DLLPREFIX_MODULE)wx.$(SO_SUFFIX_MODULE): $(MOD_LUAMODULE_MONO_OBJECTS)
$(SHARED_LD_MODULE_CXX) $@ $(MOD_LUAMODULE_MONO_OBJECTS) $(LDFLAGS)
-L$(top_builddir)/lib -L$(LUA_LIB_DIR) $(LIBS) $(WX_LIBS)
#$(WXLUA_LIBS) <-- remove this from the line above

What libs are missing for you (see below) and I wonder what the All in
One folks are doing?
> What am i doing (or getting) wrong here ?
If you have unresolved lib dependencies, as seen using ldd, you can
add search paths like this.
$export LD_LIBRARY_PATH=/path/to/the/wxLua/libs
Hope this helps,
John
