Lua on Mac/Darwin (patches)

[Anders F Björklund <afb@...>]

Hi, new to this list (and partly to Lua too)
I have some Lua-5.0.2 patches to contribute.
    ----

Not sure if you might be aware of it already,
but Darwin (the Mac OS X foundation) does not
use .so files but instead .dylib for libraries.
There is a patch in DarwinPorts already, but
I'm not sure if it has made it upstream to Lua ?
http://darwinports.opendarwin.org/darwinports/dports/lang/lua/

There is also a related issue with that if you
use "-lfoo -lbar" on Mac OS X, it *always* uses
shared libraries if they are available. On e.g.
Linux it would prefer the static libs instead.
So I added a "sobin" target to the Makefiles,
and made the regular target do a static build...
(by including the actual library files directly)

The cleaned up patch regarding Darwin/Mac OS X is at:
http://www.algonet.se/~afb/lua/lua-5.0.2-darwin.patch

It also addresses the lack of a DESTDIR, which is good
to have if you are making a package for instance ?

    ----

Part two is about running the programs on Mac OS
(either Mac OS 9, or Mac OS X without the console)
There is a add-on to CodeWarrior called "SIOUX",
which makes it put up windows with input/output
and optionally a dialog for any program arguments.

It's a nice complement to the regular (shell)
versions of the programs, and I've used it to
make a combo build of "MacLua" that works on
both Mac OS 9 (with CarbonLib) and Mac OS X...

It only requires a small patch, in order to initialize
the console on "macintosh" (i.e. before Mac OS X arrived,
if you want the window there you have to add -Dmacintosh)
I didn't prompt for arguments to "lua", since it runs just
fine in the interactive mode without any such extras, but I
did for "luac" since it can put them to good use. There are
also pre-built "MacLua" binaries available from my new page
about it at: http://www.algonet.se/~afb/lua/ ("MacLua 5.0.2")

The mac-conditionalized patch is at:
http://www.algonet.se/~afb/lua/lua-5.0.2-mac.patch

BTW. Lua script files need Mac line endings on the Mac.
(I used 'TEXT' type for scripts, and 'CODE' for chunks)

    ----

Neither patch should hurt other platforms,
so I'm hoping they can go into Lua 5.1 ?
