Minetest on Rasbpberry Pi

[AgentNagel42]

Lol I could only afford for my pi as my pc up until a couple months ago, I used my friends computer for minetest. lol.

[philipbenr]

I heard it runs better on the raspberry pi 2... Quad core @ 900MHz ARM Cortex v7 It is overclockable, and some have even made it to 1GHz fine. The 1GB of RAM really helps too.

[Amicadi]

I have an Rpi2, I could try building MT from source. I don't do much with it, it pretty much just sits around with Drupal running on top of Apache, so it wouldn't matter if it Sat there for a couple days compiling.

Heh, it doesn't take couple of days. Compile times are around 1 hour for Irrlicht and around 30 mins for Minetest (Compiling directly at Rasperry Pi 2 device). My built (OpenGL 2.1) got running at 3fps. Then I spent hours trying to compile Irrlicht with OpenGL ES support without luck.

At the profiler (F5 x 2) can be seen that the mainloop_draw is at 100% almost constantly. Other loops take almost no processing time. I believe the issue is OpenGL / OpenGL ES

That's a pretty bad result. The compile time is fine - doesn't matter if it takes a while to compile. But 3 fps is really a bit low. Far lower than on smartphones and tablets. Of course the view range is low there. The resolution and view range may matter as well.

That result is for Raspberry pi 2 with no overclocking running Minitest at window size 800x600 running at official raspbian-2015-05-05 Xserver with display configured as 1184x624 pixels.

With these extra options:

enable_3d_clouds = false
enable_particles = false
enable_shaders = false
leaves_style = opaque
viewing_range_nodes_min = 48
viewing_range_nodes_max = 48

So, very very low as you can see. Even with viewport on my feet I get no fps change, stuck at 2-3 fps. Pretty low and unplayable. Android Minetest is OK, tho... and just because irrlicht is compiled with OPENGL ES support for android version, I guess :-)

[philipbenr]

I heard there was a way to get Minetest to run at 20ish fps on a raspberry pi model B+. 4aiman and a couple others did get it running... Take a bit of time searching and you'll find it...

Do you mean this?

Did somebody try glshim for hardware acceleration?
https://github.com/lunixbochs/glshim

//EDIT: It works. I tested it with MT 0.3.1. Text is unreadable, some textures are distorted but the framerate ranges from 3-20fps I guess (although it goes down the longer you play).

Tutorial on how to set up glshim:
http://www.raspberrypi.org/phpBB3/viewt ... 4&p=479445

I also found this:

I get between 11-15fps when I am running minetest from Raspbian using the new Mesa3d vc4 OpenGL 2 driver on a RaspberryPi 2
You can read more about this new driver here: https://www.raspberrypi.org/forums/view ... 05#p802205

I haven't tried yet, but I believe that Minetest compiled along with irrlicht with OpenGL ES support (as Minetest android version is compiled) would be the correct way (and would have better performance) for Raspberry pi. or?

[AgentNagel42]

This seems promising, if we could build it and somehow solve the "slowing over time" somehow. It would take some optimising, I'm gunna try and get in touch with one of the devs over at the pi forum and see if we can get some help

[Amicadi]

Minetest with glshim at Rasberry pi 2 executed as:

LD_LIBRARY_PATH=/home/pi/glshim/lib LIBGL_FB=1 minetest

Fails with this output:

libGL:loaded: libbcm_host.so
libGL:loaded: libvcos.so
libGL:loaded: /opt/vc/lib/libGLESv1_CM.so
libGL:loaded: libEGL.so
ACTION[Main]: Irrlicht Could not create GLX window
ERROR[Main]: Could not initialize game engine

Same failure and output for Minetest at raspbian-2015-05-05 repository and the version compiled by me (along with irrlicht 1.8.2 with OpenGL support)

I guess this is because glshim only translates Open GL 1 to OpenGL ES 1???. Bloboats works very nicely with glshim at raspberry pi 2, tho :-)

So, now I am trying Minetest with Mesa3d vc4 OpenGL 2 (which translates OpenGL 1 and 2.1 to OpenGL ES 1 and 2) https://www.raspberrypi.org/forums/view ... 05#p802205 ... just to check if Minetest is playable with this driver at RPI2

[FreeLikeGNU]

I'd be happy just to run MT as a server on an RPi2, has anyone found this to work well?

[philipbenr]

I have heard that it runs fine. I think that was even stated earlier in the thread...

[Amicadi]

I tested today the available raspbian patched with Mesa3d vc4 OpenGL 2 images at http://sukzessiv.net/~gohai/vc4-buildbot/build/ (at the moment of writing this post 20150808-1312-vc4-image.zip and 20150821-1625-vc4-image.zip) and I was able to run Minetest in none of them. Minetest terminates with no output log... I was able to run and play for a while with the Processing 3D application. But, well, raspbian patched with Mesa3d vc4 OpenGL 2 looks like is right now in development state, so I think I'll keep looking at it.

[Dartmouth]

Yes, minetestserver runs nicely on the RPi, although I haven't tried with several players or heavier mods (technic + pipeworks or mobs) yet. Mapgen is just a bit slower, but it doesn't really hinder gameplay.

[Ivà]

I'd be happy just to run MT as a server on an RPi2, has anyone found this to work well?

I have an RPi 1 (1 not 2 :) ) running a home personal server with 3 people playing on it simultaneously and it works reasonably well.

Bottleneck on RPi1 is the lack of CPU power, so for example when it generates new map freezes for a while.

[4aiman]

Ivà is right.

Generating a whole map on a desktop and then copying that to RPi helps to run almost any subgame relatively "normal" if the use of entities and serialization is restricted (i.e. no mobs, as few "minetest.show_formspec" calls as possible, as few writes to a disk as possible).


Just a note: use qemu or cross-compiler to compile for armhf. RPi does that very slow (it took my nearly 6 hours for my RPi to download all dependencies, libs, compile those and finally start a server).

[Amicadi]

I continued trying to compile Minetest as client with OpenGL ES 2 for enjoying a decent framerate in my Raspberry pi 2.

Finally I got Irrlicht (ogl-es branch) compiled with OpenGL ES 1 and 2 support.

Then, I continued compiling Minetest:

cmake . -DBCMHOST=1 -DENABLE_GLES=1

returned:

Here I got stuck. Looking around for a solution I found Megaf's attempt trying the same and with same result: https://gist.github.com/Megaf/bcae0c623ca46ca29773

Any ideas?

[4aiman]

The last time I've tried, it worked like a charm...
I'll try to build the latest dev MT by tomorrow's morning and let you know about it.

PS: what is BCMHOST?

Did you try building Minetest with OpenGL ES support and it worked? If so... you are my man :-)

BCMHOST? you are right, I have no idea. I think I saw it somewhere or maybe something at my .bash_history from other compilation (EDIT: yes, from glshim), but I see that it is completely ignored at cmake :-P

Indeed, BCMHOST=1 flag should be: -DRUN_IN_PLACE=1

I got same error.

[4aiman]

I did, and it worked...
... but that was a little while ago :)


I've tried to compile the latest MT last night, but sadly it didn't finish even half of it when I came up.
And I'll be too late at home today to be able to check what's going on or to post some updates here.
So, it looks like Friday will be the day.


I also have an RPi emu, so I'm trying to build there right now.

[Ivà]

Uhmmmm... 4aiman I compile the git MT server on my RPi 1 in about 90 minutes. I don't use any special trick to do it and my RPI 1 is only slightly overclocked (800 MHz).

[4aiman]

Try performing a "clean" compilation and see the difference.

BTW, if you're able to do what is needed, then it would be cool to share your way of doing it and free me from performing useless activity ;)

[4aiman]

@Amicadi

You need to either build OGLES Irrlicht or supply a egl header and library.
The first way worked for me. (Haven't try the second way at all.)

Anyway, you'll need to install libgl-mesa-x11-dev (look through this thread to find the exact name - it's not that long)
I
Then search for header and libs in /opt/vc/include and use those to build the client.


PS: This

OpenGL ES
EGL_INCLUDE_DIR - directory that contains egl.h
EGL_LIBRARY - path to libEGL.a/libEGL.so
OPENGLES2_INCLUDE_DIR - directory that contains gl2.h
OPENGLES2_LIBRARY - path to libGLESv2.a/libGLESv2.so

doesn't work without ENABLE_GLES=1

As I said before I don't do any special trick, just git clone, cmake and make. Note that I said that I'm only compiling the server, not irrlicht or opengl or something else.

Compiling the server took me less than half an hour on the quadcore RPi2...

@Ivà (may I call you just "Iva"? I don't have "à" in my kb layouts)
Well, I'm compiling the entire Minetest - client and server :)
Haven't tried to build server only.


@Amicadi
I'm still away from my RPi but I'm using a virtual RPi to build MT at the very moment.
Once I'm done, I'll share the *.img files I use as well as the tutorial on how to setup a virtual Pi.

Gotta go now...

Continuing with Minetest compilation with OpenGL ES support.

Minetest linking is done by the command at /home/pi/minetest/src/CMakeFiles/minetest.dir/link.txt

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

Here there is somethings missing. As seen, Irrlicht is linked without -lGLESv2 or -lEGL flags and -L/opt/vc/lib is not there which seem to be mandatory according to https://www.raspberrypi.org/forums/view ... 3&p=259277

so, I changed the linking command for:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

/usr/bin/c++   -DNDEBUG -Wall   -ffast-math -Wall -pipe -funroll-loops -O3 -fomit-frame-pointer  ...Long list of object files... ../bin/minetest -rdynamic -lz /home/pi/irrlicht/ogl-es/lib/Linux/libIrrlicht.a -lGLU -lGL -lGLESv2 -lEGL -lX11 -lXext -ljpeg -lbz2 -lpng -lz -lX11 -L/opt/vc/lib -lXext -lopenal -lvorbisfile -lvorbis -logg -lsqlite3 lua/build/liblua.a -lgmp json/libjsoncpp.a -lGLESv2 -lEGL -lX11 -lXext -lrt -lpthread -ldl -lXxf86vm -lcurl -Wl,-Bstatic -lfreetype cguittfont/libcguittfont.a -Wl,-Bdynamic -ljpeg -lbz2 -lpng -lopenal -lvorbisfile -lvorbis -logg -lsqlite3 -lgmp -lrt -lpthread -ldl -lXxf86vm -lcurl /home/pi/irrlicht/ogl-es/lib/Linux/libIrrlicht.a -lz -Wl,-Bstatic -lfreetype -Wl,-Bdynamic


And then I executed the whole command. I succeed linking and I got minetest binary at /home/pi/minetest/bin

I add the line:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

video_driver = ogles2


to minetest.conf and I execute minetest who complains about the shaders location. So, I copied irrlicht media folder (which contains the shaders) to /home/pi and executed it again getting:

Automatically selecting world at [/home/pi/minetest/bin/../worlds/world]
ERROR[Main]: Irrlicht: Bad Display ----> EGL_BAD_DISPLAY
Floating point exception

Am I getting any closer? :-)

[Amicadi]

I Compiled Irrlich with loglevel set to verbose, and added debug_log_level = 4 to minetest.conf

at first try:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

So, I made some changes at CEGLManager.cpp (initialize function):

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

#elif defined(_IRR_COMPILE_WITH_X11_DEVICE_)
        EglWindow = (NativeWindowType)Data.OpenGLLinux.X11Window;
--      EglDisplay = eglGetDisplay((NativeDisplayType)Data.OpenGLLinux.X11Display);
++      //EglDisplay = eglGetDisplay((NativeDisplayType)Data.OpenGLLinux.X11Display);
++      EglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);


Then eglInitialize was sucessful, but then I got this log:

so I changed CEGLManager::generateSurface() function:

Code: Select all

-- #ifdef EGL_VERSION_1_3

After this modification, I got:

I guess that Irrlicht ogl-es needs some more code for EGL 1.4 to work in other devices than ANDROID_DEVICE. Irrlicht ogl-es 1.9.0 is in alpha version, so, who knows... :-)
