LuaX modules

[Asko Kauppi <askok@...>]

( This is about experimental LuaX codebase, not yet anything you can  
download and start using right away. )


This night, I got LuaX modules to compile from the same source, to  
either "native" Lua 5.1 binary modules, or to version-independent  
(not linking to liblua) LuaX modules.

This promises good for us all, since the LuaX modules of future  
releases will be easily "detachable" from the main release, for use  
in other environments. LuaX itself shall continue its journey to  
become a "virtual programming platform" based on SDL, Lua, UTF-8 etc.

Getting this far provides some practical issues, i.e. in the naming  
of the binary modules. See attached log trail, are the names used  
there good:

	lua51-serial.bundle/so/dll	Lua 5.1 linking Serial port module
	luax-serial.bundle/so/dll	LuaX linking Serial port module

Here are the commands used for the compilation (only the one -D flag  
differs):

[iMac:trunk/Modules/Serial] asko% make
c++ -fPIC -bundle -Wall -O2 -o lua51-serial.bundle \
   -I ../Sys/ -I/sw/include -L/sw/lib -llua \
   -DGLUA_NOHOST -I../../Sources ../../Sources/gluax.c \
   serial_module.c

c++ -fPIC -bundle -Wall -O2 -o luax-serial.bundle \
   -I ../Sys/ -I/sw/include -L/sw/lib -llua \
   -DGLUA_DYNAMIC -I../../Sources ../../Sources/gluax.c \
   serial_module.c

[iMac:trunk/Modules/Serial] asko% ls -al

In addition to module source code, one will need gluax.c/h, nothing  
more (and Lua headers + library for "normal" linkage). For LuaX  
linking, Lua is not required (there will be a proxy module bridging  
Lua core to LuaX modules, transparent to applications).
