The README file included by ./play.it is illuminating:
Three libs from [UTPGPatch451.tar.bz2] have a [symbol conflict] with modern
libstdc++.so.6. Sadly `objcopy --redefine-sym` can't [redefine dynamic symbols]
and hexediting just delays the crash to loading Pit of Agony. Use [elfhash] to
replace the symbol with one the same length and rehash the elf.

It should also be noted that this build is based on the unofficial UTPG 451 patch.

I can also now confirm that the "Signal: SIGIOT [iot trap]" error when changing game modes is a product of using Stéphan Kochen's OpenGLDrv renderer. When using SDLGLDrv it works fine.

Quoting: BillFlemingThe author of this article really didn't do their research. The game runs fine without needing a patched mesa.You just need to install some extra audio packages and launch the game using a special command for the audio.

Trust me when I say that I have been aware of this issue for years and that I spent a great deal of time researching when crafting this article. I did miss your AUR package, but that is because I deliberately avoid distribution specific methods so as not to exclude people with other setups. All that being said, I am happy to say that your build of the game does work.

Looking into it, the "ut99v451-linux.2019-07-21.tar.gz" package you are using has hacked game binaries that have been made to work around the symbol collision with modern versions of libstdc++ which in turn produced the segmentation fault with Mesa. This is NOT TRUE of the last official release of the game, which is provided by the "ut-install-436-GOTY.run" installer I used.

Again, I will admit to not being aware of this hacked version, but considering that it only shows up on Google from either ./play.it or the gog-unreal-tournament-goty AUR package I can hardly be blamed for that. The vast majority of articles and sources online do not refer to this package, likely because it is not official and did not even exist before last summer.

Quoting: BillFlemingThe game's old renderer is also still usable so you don't even have to mod the game to play, but it won't support super high res. (2560x1080 works, 2560x1440 didn't for me)

I never claimed that it did not work. I did need to supply a new audio device in order to get better sound, but the original OpenGL renderer did indeed work fine given its limitations.

Quoting: rea987What you have linked as OpenGL renderer is same OpenAL. That's a mistake I guess. Is the third party OpenGL renderer the same Stéphan's Kochen OpenGLDrv based on Chris Donhal's enhanced OpenGL renderer?

Okay, that one is my bad. It was supposed to link to a compiled version of Stéphan Kochen's OpenGLDrv renderer like you said.

Quoting: Perkeleen_VittupääSoo, could all this be possible to package somehow to a state that even a non-tech-savvy random occasional gamer could then enjoy Unreal Tournament on Linux? :huh:

Well, now that I have a binary that works without issues, I will at least be writing a guide on how to get Unreal Tournament working on modern Linux distributions as a sequel to this article.

Quoting: appetrosyanSadly, not many of those games are OpenSource, and it’s only a matter of time when this issue crops up

Which is as true on Windows as it is on Linux though remember. All games eventually succumb to time, we're just in an interesting position thanks to Wine/Proton that can at times run games Windows 10 now cannot heh.

Yeah, there is nothing about Windows that makes it less susceptible to these problems than Linux. This is just one of the benefits of WINE being a compatibility layer. It grants compatibility, even for older titles.

Quoting: adamhmTry starting them with: taskset 0x1 <command>
(make sure to disable CSMT before doing this)

That does indeed do the trick, thanks.

Quoting: legluondunetI wroted 3 Lutris scripts installer for this games:
- Heretic 2

I just tried your Lutris script for Heretic II incidentally, and it hangs for me at "Extracting data.tar.gz". Any idea what is going on there?

Well, I am going to have to eat my hat, at least as far as Unreal Gold is concerned. The Lutris script does in fact work and the game launches just fine.

The same can not be said for Unreal Tournament or Rune when installed from Lutris. I wonder if this is because of the work done on the Unreal 227 patch?

Quoting: KayKay91Shouldn't removing libgcc and libstdc++ from game's folder fix this? Lutris has a script called "Mesa fix" for Unreal Gold which basically removes these files after using "GOG + OldUnreal 227i" script installer.

I can confirm that not having those libraries in the System folder makes no difference to Unreal Tournament and the game will still segmentation fault.

On the Lutris page for Unreal Tournament (1999) I also can not help but notice it says this:
"If using open source mesa drivers, switch to software rendering in the game's .ini config file."

I am going to try the Lutris script for Unreal Gold, but I am not optimistic.

Try this command in a terminal before launching the game:
export MESA_EXTENSION_MAX_YEAR=2000

A lot of older Quake engine games struggle with the amount of OpenGL extensions that are now exposed.

Like Patola said, this was done as one of Ryan's Patreon projects. If you want to support his work then you can do so by giving to him directly.

I literally just got the Loki version of this on disk delivered last Friday:

This is hilarious, especially if the port does come to GOG.com meaning I never have to use the disk.

Quoting: cprnOoooh... I don't like the new graphics. :( They didn't keep the style.

Which is why the old graphics are still available as a toggle.

Quoting: soulsourceThe original game is "native" as well, as it is written in Java.

Okay, still more than happy to have it count as a Linux sale.
