Viability of Raspberry Pi Zandronum server

[Balrog]

Just a quick question about the viability of running the Zandronum server binary on a Raspberry Pi. I'm not asking for a port, as I'm fully prepared to roll my own; I just want to know if there are any impossibilities I should be aware of. I have the 512MB revision, so RAM shouldn't be too much of an issue for just running one server at a time. More of a concern is the relatively wimpy ARM core.

[Eonfge]

As far as I know, most of the code is not platform specific, witnessing the large amount of ports for other platforms. Other then that, running just the server would not be the issue since it does not require much besides a good bandwidth/latency.

Issues you might have, could be caused by the network adapter and the code connected to it.

Stick to deathmatch or smaller co-op wads and you will probably be OK. Don't expect hr2 + brutal doom though.

One thing I would like to see with the Zandronum server is for it to one day require no libraries. Torr did a great job of removing most of the libraries that the client needs (particularly FMOD) but I think there are some remaining.

IIRC SDL is the only dependency left in the server. If you'd like to see this go as well, a tracker ticket won't hurt ;).

Balrog, did you ever succeed in porting the server to Pi? I'm also interested

[mr fiat]

the pi is very overclockable ive seen a dude add a custom heatsink to it and the little thing ran quite well at oc speeds, later he added a laptop fan ontop and he reached even higher speeds at stable temps. maybe that could help.

I kinda lost interest actually

Set up a Linux box with a crosstools-ng dev environment and compile the Zandronum source with the "server only" compilation flag and you should be fine. I was never able to get mine satisfactorily sealed off IIRC, but a clean install may help with that. You could also compile directly on the Pi, but who wants to put up with compilation on that?

[BlueHattedEngie]

I've been trying to put Zandronum on my Pi but it kept saying

Code: Select all

E: Unable to locate package zandronum doomseeker-zandronum

no matter how many times I update the repositories (and I have entered it in correctly).
I would like to host some mods like Brutal Doom and Samsara.

[Ijon Tichy]

Zandronum doesn't have precompiled ARM binaries. And rbutl dum is probably too much for an RPi.

[Fincer]

I compiled zandronum-server on Raspberry Pi using the following settings.

Be Informed: You can't actually run the server by following these instructions. This is only for testing/developing purposes for people who are interested in modifying & adapting zandronum source code to ARM processor architecture.

1) If you are running Raspbian, install all dependencies & sub-dependencies (includes dh-make & dpkg-buildpackage):

Code: Select all

sudo apt-get install libasound2-dev libavahi-client-dev libavahi-common-dev libcaca-dev libdbus-1-dev libdirectfb-dev libdirectfb-extra libelfg0 libflac-dev libfluidsynth-dev libgl1-mesa-dev libglib2.0-bin libglib2.0-dev libglu1-mesa-dev libjack-dev libjack0 libjpeg8-dev libncurses5-dev libogg-dev libpcre3-dev libpcrecpp0 libpng12-dev libpthread-stubs0 libpthread-stubs0-dev libpulse-dev libpulse-mainloop-glib0 libreadline-dev libreadline6-dev libsdl1.2-dev libslang2-dev libsndfile1-dev libtinfo-dev libts-dev libvorbis-dev libx11-dev libx11-doc libxau-dev libxcb1-dev libxdmcp-dev libxext-dev mesa-common-dev x11proto-core-dev x11proto-input-dev x11proto-kb-dev x11proto-xext-dev xorg-sgml-doctools xtrans-dev libssl-dev libssl-doc libbz2-dev nasm autopoint debhelper dh-make gettext html2text intltool-debian libgettextpo0 libmail-sendmail-perl libsys-hostname-long-perl libunistring0 po-debconf mercurial cmake

For other Linux distributions, see http://wiki.zandronum.com/Compiling_Zandronum_on_Linux

2) Download and extract zandronum source:

Code: Select all

mkdir -pv $HOME/zandronum_build && \
cd $HOME/zandronum_build && \
hg clone https://bitbucket.org/Torr_Samaho/zandronum && \
mkdir -pv zandronum/buildserver && \
cd $HOME/zandronum_build && \
v=$(wget -q -O - http://www.sqlite.org/download.html | \
sed -n '/>Source Code</,/zip</ s/.*sqlite-amalgamation-\(.*\)\.zip.*/\1/p') && \
wget -nc http://www.sqlite.org/$(date +%Y)/sqlite-amalgamation-"$v".zip && \
unzip -j sqlite-amalgamation-"$v".zip -d zandronum/sqlite

2) Modify $HOME/zandronum_build/zandronum/v_text.cpp file using these instructions: http://forum.zdoom.org/viewtopic.php?f=2&t=47275

3) Run

Code: Select all

cmake -i $HOME/zandronum_build/zandronum

Disable ASM (NO_ASM=ON)

4) Run

Code: Select all

cd $HOME/zandronum_build/zandronum/buildserver && \
make clean ; \
cmake -DCMAKE_BUILD_TYPE=Release -DNO_ASM=ON -DSERVERONLY=ON .. && \
make

Compilation fails at 19%. Remove all "-msse" flags from $HOME/zandronum_build/zandronum/buildserver/dumb/CMakeFiles/dumb.dir/build.make and run "make" again.

Compilation takes time (2-3 hours?) but should be successful.

5) Move compiled files to correct locations:

Code: Select all

sudo mkdir -p /usr/share/zandronum && \
cd $HOME/zandronum_build/zandronum/buildserver && \
sudo mv brightmaps.pk3 zandronum-server skulltag_actors.pk3 zandronum.pk3 /usr/share/zandronum/ && \
sudo printf "#!/bin/sh\nexec /usr/share/zandronum/zandronum-server '$@'" > /usr/bin/zandronum-server && \
sudo chmod 755 /usr/bin/zandronum-server

6) Run

Run zandronum-server by using command

Code: Select all

zandronum-server

Issues:

- No libraries compiled (liboutput_sdl.so & libfmodex*.so (lack of support?))
- Should OpenAL be used/adapted?. See ZDoom for Raspberry Pi (source code, github)

- Launching the server leads to the following error event (library errors):

The instructions may have little lack of precision so feel free to adapt them to your needs.

[Torr Samaho]

I have the zandronum server up and running on a Raspberry Pi B 2.

The only code changes required are here (the "0xFF" change should fix the crash on start Fincer experienced) and the CMakeList changes of the dumb library from here. If anybody is interested in using a Pi to host servers, I can integrate the necessary changes into the Zandronum source repo.

[antiriad]

I'm interested, but I have a rPi 1 (too low specs?).
A permanent rPi server would be a great solution for long coop gameplay (like Hexen) since it's not possible to save.
Thank you!

[ibm5155]

Just saying, isn't better to get a more powerfull machine for servers? I mean, even my old Pentium 3 1GHz with 1,5Gb of ram failed to be a playable armageddon and zdoom wars server :S

EDIT: I actually got curious about how bad/well would my k6-III+ 400MHz run as a server

EDIT: I learned a magic spell, so now, for each post I made, Decay will post next

[ibm5155]

bandwidth would not be a problem since the test was going to be over lan.
About the resource intensive, maybe, but, there're no limits to zombo com, so I'll test it...

[antiriad]

It is possible to have a "quick and dirty" binary, to test it on my Raspberry 1 (512) with a Hexen Coop?
Thank you

Unfortunately, I don't have a Raspi 1 at hand and I also don't have the time to set up a cross compiling environment for this. So unless anybody else volunteers, you'll need to compile this yourself. Assuming the Raspi 1 accepts the same C++ code the Raspi 2 accepted, this shouldn't be too difficult, but will take quite a while since the Raspi 1 CPU is quite slow.

Aside from compilation time, do you think could a Raspberry 1 manage fluidly a basic online session (like a Hexen coop)?
Thank you.

Difficult to say, but I think chances are good that hosting Hexen on the stock maps with a few players will work fluidly.

Interesting... where could I pick, eventually, the fixed source code?
Thanks

Zandronum 2.1.2 should already work without changes. You can grab it from our stable source repo. In order to be network compatible with the official 2.1.2 binaries, you should clone the code from here using the 2.1.2 tag.
