As to Callumari's comment, try to contact jose1711 directly to see whether they still have the time and inclination to maintain it. If they do not respond within a reasonable timeframe (two weeks at least), you may click the "Submit Request" link on this page and request that the package be orphaned. Once in an orphaned state, the package may be adopted by another AUR user.

This package can - and should - be made to compile with GCC 16 by targeting the "gnu17" standard.

I have a fix! I can commit if the maintainer would allow, however I have literally never committed to the AUR before, so I don't know what the process is.

Edit2: gcc13 would have worked as well. CC=gcc-13 paru -S darkplaces

Edit: I install gcc11 from AUR. Took forever. Then: CC=gcc-11 paru -S darkplaces worked. I'm sure there is a way to patch it so it works with the newest gcc, but that is far beyond my modest abilities. || Doesn't compile no more.

In file included from ../../../quakedef.h:45, from ../../../sys_linux.c:16: ../../../qtypes.h:9:26: error: cannot use keyword ‘false’ as enumeration constant 9 | typedef enum qboolean_e {false, true} qboolean; | ^ ../../../qtypes.h:9:26: note: ‘false’ is a keyword with ‘-std=c23’ onwards make[3]: *** [makefile.inc:556: sys_linux.o] Error 1

I switched the standard to c99 and c11. Then I had to add a few more include files for strings and sys/select and what not. Then it told me the array wasn't a multiple ... actually, here the error:

../../../dpsoftrast.c:240:22: error: size of array element is not a multiple of its alignment

looks like math.h is missing as well.

Anyway, that's far more than I'm able to. Help anyone?

DarkPlaces-Quake build 16:37:35 Feb 21 2022 darkplaces-glx crashes often when I do vid_restart. darkplaces-sdl doesn't let me set snd_channels to 8. Always sets it to 6 - which ends up being stereo anyway. Also it hogs my mouse buttons so mumble doesn't see me pressing them.

Basically what I'm saying is, how do I compile the 2014 version my own self? Because there everything worked fine.

Edit: Never mind. I mistook the build date as release. My issues are still there though. Edit: Turns out the vid_restart was the Nvidia driver. I only use the glx version these days, so with the new drivers it's all good. Well, if it compiles.

@kleintux looks like maintainer lost interest in maintaining this. here's a patch you need to apply to fix it.

Building with gcc 11 fails with the following error:

../../../dpsoftrast.c:239:22: error: size of array element is not a multiple of its alignment
  239 | typedef ALIGN(struct DPSOFTRAST_State_Thread_s

Here's a patch that fixes this: https://bugs.gentoo.org/786288#c9

libglvnd should be a makedepend. This package does not build without GL/glx.h.
