Lua 5.1 shared libraries, on Mac

[Anders F Björklund <afb@...>]

Just tried upgrading to Lua 5.1 "final/rc",
and testing with running luaglut from lua.

http://lua-users.org/files/wiki_insecure/users/VarolKaptan/

Sadly, none of my 2 Mac targets work without
first patching the regular Lua distribution ? :(


1) "MacLua" - Mac OS 9 / Mac OS X (Carbon)
The CFM targets didn't work at all, since
none of the Mac patches had been included.

After applying the old patch for the beta,
http://www.algonet.se/~afb/lua/lua-5.1-cfm.patch
and updating the exported symbols, it compiled.

Running the MacLua/Luac sample programs required:
http://www.algonet.se/~afb/lua/lua-5.1-mac.patch


2) "lua" - Mac OS X : make && sudo make install
The Mach-O targets didn't include the ".bundle"
suffix in the default search paths, only ".so" ?

So it couldn't find the modules to load, without
renaming them or adding symbolic links to them...

File type is: "luaglut.bundle: Mach-O bundle ppc",
it is called ".so" on Linux and ".dll" on Windows.


Luaglut also had to be updated, since the old
functions "dobuffer" and "loadlib" went missing.

But I guess that was an intended change, so I
just updated the code to use the new functions:

i.e. lua_dobuffer -> luaL_loadbuffer + lua_pcall
http://www.algonet.se/~afb/lua/luaglut-0.4-lua51.patch


Finally, it did work OK! Just wondered what the
status of including the Mac patches were, or if
Mac is not really a supported platform for Lua ?
(all patches at http://www.algonet.se/~afb/lua/)

The GLUT demos are working fine in both Mac OS.
(both spinning the teapot, and loading textures)


Is it possible to add support for CFM libraries
and Mach-O loadable bundles (i.e. .bundle) yet ?

#if defined(LUA_USE_MACOSX)
#define LUA_CPATH_DEFAULT \
	"./?.bundle;"  LUA_CDIR"?.bundle;" LUA_CDIR"loadall.bundle;" \
	"./?.so;"  LUA_CDIR"?.so;" LUA_CDIR"loadall.so"
#else
#define LUA_CPATH_DEFAULT \
	"./?.so;"  LUA_CDIR"?.so;" LUA_CDIR"loadall.so"
#endif

Added *both* .bundle and .so, since some use "so".
(for instance: Perl uses .bundle, Python uses .so)

PS.
The default Lua "make install" is also missing the
*extra* ranlib after install as required by Darwin:

ld: table of contents for archive: /usr/local/lib/liblua.a is out of 
date; rerun ranlib(1) (can't load from it)
