So this is really super cool! Ryan C. Gordon has written a Wine like program to run OS/2 programs!
Using 32bit Linux, and some native libraries, 2ine can load up an LX (32bit) executable and try to run it under Linux, much in the same way that Wine can run Windows programs.Â And yes it’ll run EMX built stuff.Â Although keep in mind the original Microsoft based languages, programs and tools is all 16bit.Â After the whole Windows 3.0 thing and the split of Microsoft from the OS/2 project all their tools are either 16 bit, or 32bit LE format, which IBM had dumped for the LX format once OS/2 2.0 had shipped.
You can read about his incredible progress, and all the trials and tribulations of running OS/2 programs, along with the craziness that is thunking back and forth to the 16bit space for the old VIO calls that had never were updated to 32bit in that transition phase where a good chunk of OS/2 never was updated from 16bit, over on his patreon page here.
Attempting to run anything 16bit or LE will give you:
not an OS/2 LX module
But let’s try my crazy Win32 hosted EMX 0.8h cross compiler!
C:\emx\demo\dhry>gcc -v dhyrstone.c -o dhyrstone.exe
gcc version 2.5.8

And now running that on Linux…

You’d never know that this was an OS/2 program, if I didn’t tell you.
I tried the old 87 Infocom interpreter, and it’ll run great too!

You are standing at the end of a road before a small brick building. Around you
is a forest. A small stream flows out of the building and down a gully.

Again it’s works so well it’s amazing!
You can find the 2ine source over on icculus.org here.Â I had to tweek the heck out of the CmakeList.txt to get it to build, and since I was interested in the command line, I ended up disabling all the SDL / PM stuff, and make sure I had the ‘wide/unicode’ version of ncurses installed.
I don’t think there really was any killer 32 bit OS/2 applications, but with clean room versions of:
Not to mention being able to call into Linux DLL’s and using ‘clean’ OS/2 DLL’s would let you embrace and extend OS/2.. Or maybe even let you build the proverbial fantasy of both RISC & 64 bit OS/2. …..
