Based on that alone it's impossible to say what could be wrong. The actual error message must've been shown earlier on. Maybe you could try piping the output from the compilation to a file?

make > output.txt 2> errors.txt

Then let's see what gets printed into those two files.

thank you for that. here is what i got

so it to me looks like it cant find the openGL verions it needs on the Pi4

I did some closer investigating using my Raspi 400 (Raspberry Pi OS 32-bit) trying to build Doomsday 2.0.3.

It's bad news, though: looks like the OpenGL 2.1 compatibility profile API is not available via the provided Qt 5 packages, and those are required for OpenGL in Doomsday 2.0.3. glxinfo shows that the Mesa OpenGL implementation does support version 2.1, but apparently it hasn't been included in the build of Qt 5.

I also couldn't locate OpenGL headers newer than 1.4 and had to supply those manually.

The bottom line is that in order to run on Raspberry Pi, Doomsday needs to support OpenGL ES, since that's what is preferred on ARM-based platforms.

The latest status in the master branch (Doomsday 3.0) is that I've switched away from Qt entirely, which sidesteps this issue, but there OpenGL 3.3 is required, so this will not help either. Work on OpenGL ES support is underway, though.

thank you for looking in to that, its a bummer for sure.

i belive there is talk and news about the pi getting OpenGL 3.x or something. so maybe if it gets in the main stream, but who knows when that will be.
so ill just keep my eye on that for something down the road....way down the road. lol

again
thank you for your time
