OS/2 - ArcaOS Santa's List for 2025

[Paul Smedley]

What about mesaGL? I don't remember its current status. A slow renderer would still be better than no renderer at all...

I visited it, seven years back, and got it compiling and the examples ran good. [https://github.com/OS2World/LIB-GRAPHICS-WarpMesaGL.
Problem is that it is old. Gives gl.h while now it is gl2.h that is required.

sh*t. I was hoping there was a better solution.
AFAIK also PortableGL has its limits (TinyGL is good but even more limited).

Mesa GL's softpipe might be sufficient...

It has. While the examples worked, I couldn't get it to work with Classicube.

OK I've hacked mesa, python and meson enough to get a build.ninja

https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/util/memstream.c is a problem as we don't have open_memstream() and I'm not sure how to implement it on OS/2.

I stubbed this for now.... I have latest mesa mostly build.... but meson has no idea how to make an OS/2 DLL, so there may be some manual hackery required to get past errors like:

Have you looked at the old port? https://github.com/OS2World/LIB-GRAPHICS-WarpMesaGL
This built with VACPP and has the Presentation Manager fixes. IIRC, the build system was redone.

 Paul,

  Don't know if it helps, but Ko Myung-Hun just did a new meson: https://github.com/komh/meson-os2/releases/tag/1.6.0

Whoa, didn't find it before. I've got at least two interesting projects which build with meson. Currently I've got no time to work on ArcaOS, but willing to start again asap.

Looking at the checkins, there don't appear to be any OS/2 specific changes in this repo
