Today, I successfully compiled Lua 5.2.2 for MS-DOS using DJGPP. I want to make it a standalone EXE so I can distribute it. I read that pmode11b.zip is supposed to do it but I don't really understand how to use it. Is there a way to make a standalone EXE that will run by itself without DJGPP being installed? Any help would be greatly appreciated.
P.S. DJGPP is great, I love it. Keep up the great work!

Any particular reason? LUA_ANSI? Did you know that Juan already
did a port of that for us? See /beta/v2tk/ :
http://na.mirror.garr.it/mirrors/djgpp/beta/v2tk/lua522b.zip

You mean bundle the DPMI server? Not needed if you're running
under DOSEMU, DR-DOS 7.03, OS/2, Win9x, or WinNT (e.g. XP 32-bit).
Only in raw DOS without CWSDPMI (or similar) already present will
this be a minor problem.
Though it doesn't hurt either way, 20 kb is pretty small.

AFAIK, latest is PMODE/DJ 1.3, see /current/v2misc/ or CWS' homepage:
http://na.mirror.garr.it/mirrors/djgpp/current/v2misc/
http://homer.rice.edu/~sandmann/
http://homer.rice.edu/~sandmann/cwsdpmi/pmodedj.txt
However, PMODE/DJ is darn old, and while I don't fully understand it,
I don't trust it nearly as much as CWSDPMI r7 (circa 2010). I think
that was back (pre-r5) before CWSDSTUB existed, so (IMHO) there's
really no major need for preferring or using PMODE/DJ (that I know of).

DJGPP doesn't have to be installed, only a small DPMI server since all
v2 programs need DPMI. By default, the stub tries to call CWSDPMI.EXE
if no other is enabled. If you want to make it not require an external
DPMI host, you can "exe2coff blah.exe" and then "copy /b cwsdstub.exe
+ blah blah.exe" .

It still works, but there isn't a lot of active work being done
on it. Quite honestly, most developers moved on to greener pastures
(to put it mildly).

You should only need to follow the two steps Rugxulo posted.
At a DOS command prompt, in the LUA directory, with the DJGPP
environment and path variables setup in order to locate
exe2coff.exe in the DJGPP bin directories:
E.g., after initializing your DJGPP setup, do something like:
C:\lua522\exe2coff lua522.exe
C:\lua522\copy/b cwsdstub.exe + lua522 lua522.exe
What is the name of the lua executable?
What directory is the lua executable within?
Change the above example to fit, if different.
If the LUA build didn't produce a .exe, e.g., lua522 without
a .exe extension, you only need the second step.
> Could you elaborate a bit on how to use the cwsdstub?
To produce a stand-alone executable, cwsdstub must *replace*
the default DJGPP executable stub. That's done by
removing the default stub and pre-pending cwsdstub to the
main executable. 'exe2coff' removes the default stub
from .exe's, leaving the main executable. The DOS command
"copy" (not "xcopy") in binary mode - "copy/b" - combines
the binary objects (stub and main executable) into a single
file.

AFAIK, the only advantage to Juan's port is that it
supports .so (via /beta/ 2.04 DXE3) and uses readline.
If you don't need that, you can compile it yourself.
IIRC, preferred support is (in order) posix, generic,
ansi. (Those may or may not work how you expect.)

1). wget http://www.lua.org/ftp/lua-5.2.2.tar.gz
2). enable djgpp (set PATH and DJGPP)
3). djtar -x lua*.tar.gz
4). cd lua-5.2.2\src
5). ren luac.c *.c~
6). gcc -s -Os -ansi -Wpedantic -DLUA_ANSI *.c -o lua.exe
7). exe2coff lua.exe
8). copy /b cwsdstub.exe + lua lua-cws.exe
9). upx --best --lzma --all-filters lua-cws.exe
10). lua-cws -e "print(36+64)"
Now you can use LUA-CWS.EXE on any DOS compatible OS,
whether there is already a DPMI server or not.
P.S. Actually, I almost forgot: Lua uses "double" (FPU)
for all numbers, so you may need an FPU emulation lib,
but that's only for very old computers that (for good
or bad) most people don't care about. If this is a
problem, you can link with "-lemu" or use 3rd-party
WMEMU (slightly more accurate??). You can also let
people optionally use emu387.dxe at runtime in order
to not have to link that in too, but you seem to be
more concerned with everything being self-contained.

I tried these commands and when I try to run the resulting exe I get "Program too big to fit into memory". I'm using a Pentium III system with 256MB of RAM so I don't think this is the case.

You must've done something incorrectly as it does indeed work
for me. However, without seeing your DJGPP setup nor knowing what
compiler switches you used nor what checksums the .EXEs have, I
can't even guess.
Anyways, here's a quick prepackaged build of such a Lua .EXE for
you, with original (.tar.gz) sources and a very kludgy makefile:
https://sites.google.com/site/rugxulo/lua-cws.zip?attredirects=0&d=1
For clarify, since download links always disappear, I'll post the
horrible makefile here. Hey, at least it uses one new feature of
Juan's recent Make 4.0 port (at least compared to 3.81), which is
good since tabs are anathema to email and newsgroups! :-)
