Raylib 6.1-dev on Windows XP

[vmunix486]

I was wondering if the new Raylib release would work on my laptop, so I downloaded it, compiled it, and it worked, but if you are wanting to try this for yourself:

• I used MSYS2 (version from 2016)
• I had to set C compiler to i686-w64-mingw32-gcc/g++
• I had to set OpenGL version to 1.1.

Now I set the OpenGL version to 1.1 because my laptop's graphics card, the ATI Mobility Radeon X300 had support up to OpenGL 2.0 and not 2.1. A side effect of not using a newer OpenGL version is that some of the graphics things don't work entirely, such as some of the examples that show of shading capabilities. I could've used RLSW but I'll test that another time.

Raylib has ran faster than any other 2D/3D software I have tested so far on this laptop. It runs circles around FLTK 1.3.11's OpenGL programs. Every OpenGL program I have tried on this laptop has always rang the CPU up to 100%, but with Raylib, the CPU barely lifts a finger, and that's saying a lot for a Netburst Pentium M.

Amazing work guys! Love the project, and I was able to make a little program in C for myself, which is at the end of the video, and I don't really code that much in C.

The video is over 10mb (~120mb), so I had to put it on YouTube. You can find it here.

I just wanted to show off that this can be done lol

@vmunix486 Wow! That's amazing!!! I didn't know it could work down to XP!

I recompiled with the software renderer (RLSW), but when I run anything compiled against it, a blank, black window appears, and the program does not show up. I'm not sure why. I'm pretty sure it still does all the processing though, because the CPU usage went to 100% when running any program rofl

I remember this also happened on Linux on a Pentium III, but that was back like a month ago, while RLSW was still being developed. I do have footage of it working correctly here, and it was also running though Mesa llvmpipe since the graphics card on the motherboard is too old to be 3D accelerated.

I attached a picture showing this with the raylib basic window:

Adding my own experiments I've had with running raylib on old Windows:

• Windows NT 4.0 using OpenGL 1.1 (Software "GDI Generic" driver)
  • Could not get hardware rendering working, seems to be an issue with 86Box.

• Windows 2000 using OpenGL 1.1 (Emulated 3Dfx Voodoo3)

.

• Windows XP using OpenGL 3.3 (Actual NVIDIA ION netbook)
  • Also demonstrating an actual project I'm working on.

My branch based on 6.0 adds polyfills for 2000/NT 4, though XP shouldn't need patches. Probably also worth adding that I am using the RGFW backend instead of the Win32 one, since, uh... when I was playing with this last year, that wasn't a thing.

On my end I used Clang with MinGW headers to build, which actually didn't require as much fuss as you'd think to work on old OSes. These usually help the most: -fuse-ld=lld -lmsvcrt-os -Xlinker /subsystem:console,4.0

For debugging, there are actually builds of gdbserver I found for old Debian releases including version 7.11 which works on 2000 and NT 4, so I was able to connect to diagnose some nasty bugs.

Build commands

Won't work on anyone else's system of course (host = macOS, fish shell), but with modifications this should be able to be adapted to Linux and Windows.
Both of these add debug flags that can all be removed.

• For NT 4.0 / Win 2000

Hope this is interesting as well!
