DJGPP isn’t supported though I keep hearing rumors that people are playing
with it.

In any case, grab the Mingw32 development environment, that’s the only
gcc-based Windows build environment that’s officially supported by SDL:

My guess is the issue w/ DJGPP is that it only supports DOS (if memory
serves me). I think the SDL requires win32… am I wrong?

Real software engineers don’t debug programs, they verify correctness.
This process doesn’t necessarily involve execution of anything on a
computer, except perhaps a Correctness Verification Aid package.

Yep, you’re wrong.

I suggested long ago (if memory serves, SDL was at 0.8 or so back then!)
that removing SDL’s threading capabilities would make it a lot easier to
port SDL to DOS/djgpp. But then, threading is already such an integral
part of SDL by now (especially with the sound core) that it’s all but
impossible to do.On Mon, 12 Feb 2001, Joe Tennies wrote:

Not true. Handling the sound interrupts directly serves the same purpose
as the audio thread, and the SDL audio is flexible enough so that it can
either use a thread or have the driver perform the callbacks directly.

SDL doesn’t use any other threads internally by default, so it would only
impact multi-threaded applications. The threading subsystem is set up with
stubs so all you have to do is link in the correct stub files.

FYI, the MacOS classic port of SDL doesn’t have thread support, and it
works just fine. :slight_smile:

See ya!

Threads can be implemented in DJGPP/DOS. There is a even a pthread()
implementation for DJGPP.

DJGPP is only for DOS and you could use one of the best libs for it :
