[solved] trouble compiling on Raspberry Pi 5 - pnacl-strip not found

[a real darling]

Has it really been almost twenty years, that somebody last got “gunned down by a real darling” or “bitten by a real darling” in Tremulous back then, and I think it is time to do it again, but when I follow https://wiki.unvanquished.net/wiki/Comp ... urce#Linux and try “fakeroot dpkg-buildpackage -b -uc”, the process fails:

Code: Select all

Any ideas? System is Raspberry Pi 5 running Raspbian Trixie.

Hi!

First thing, the Debian script may not be up-to-date (looking at the log, it is a lot!), but that's not the biggest problem. The current (P)NaCl compiler we use to build the game code is not available for arm. We're in the process of replacing it with one that works on arm, but that's not released yet.

But actually, you even don't need a NaCl compiler as only the native binary of the engine is required to run the game.

If you absolutely want to build the engine yourself, just build the Dæmon engine:

• github.com/DaemonEngine/Daemon

Then put next to the daemon binary the pkg/ folder from this archive:

• dl.unvanquished.net/release/unvanquished_0.56.2.zip

If you don't have a requirement for rebuilding the engine, just use the prebuilt engine from the same archive. There is linux-armhf.zip (32-bit) and linux-arm64.zip (64-bit) in it. The pkg/ folder should be next to the daemon binary (follow the instructions in the readme file in the zip).

Make sure your kernel runs 4k page size, this command should return 4 kB:

Code: Select all

grep "^KernelPageSize" /proc/self/smaps | head -1
KernelPageSize:       4 kB

If that displays 16 Kb instead, edit /boot/firmware/config.txt and add the line kernel=kernel8.img at the end of the file after the [all] line, and reboot. We're also in the process to remove this 4k requirement, but the current release still have this requirement.

Once the game runs, don't forget to go to the graphics option and to apply the low preset to better match the performance of the rpi5 graphics!

And welcome to the game!

Thank you, it worked. I compiled everything and moved the directory “pkg” into the directory “build”, the game runs now.

The problem I have now is, that I will have to remember how I had configured Tremulous back in the days, I will check if I have the configuration somewhere on old backups or something. Thank you

PS: If possible, you can mark this thread as solved.

[killing time]

I removed the Debian package nonsense from the wiki. NaCl gamelogic is not built by default in the Unvanquished build so if it weren't for that dreadful wiki page, there would be no attempt to use an NaCl compiler at all.

Nice!

Well, if you find it, all you can do is to inspire you from. The config files will not be compatible and for good reasons. Not only because we improved the bind system (we now have per-team binds) but Tremulous bound keys to meaningless action names. For example in my own Tremulous autogen.cfg file I see weird things like bind q "+button7" which may be the evolve menu or something like that… “button7” means nothing in Unvanquished, we have teambind 1 hw:q +activate instead, which is even a per-team bind and not a bind to an action the team code may associate with.

[a real darling]

Back in the days, I had an alien.cfg and a human.cfg, which got loaded via a binding, when I joined the respective teams, but this is a topic for another time. The most important thing is, that the game now runs in the first place. I shall hone my skills with bots or something, and, who knows, maybe one day, somebody will get bitten by a real darling again

Cheers!
