Minetest on Rasbpberry Pi

[Ivà]

I've tried to compile the latest MT last night, but sadly it didn't finish even half of it when I came up.

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 ;)

@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.

[Dartmouth]

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...

[Amicadi]

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

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 -lX11 -lXext -ljpeg -lbz2 -lpng -lz -lX11 -lXext -lopenal -lvorbisfile -lvorbis -logg -lsqlite3 lua/build/liblua.a -lgmp json/libjsoncpp.a -lGLESv2 -lX11 -lXext -lGLESv2 -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


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:

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:

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:

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... :-)

I ran a server on the Model B 512MB, and tested it...works, but i got tons of lag. :( Not tested it on any later models of the pi.

Does anyone have a solution

[wziard]

Continuing with Minetest compilation with OpenGL ES support.

Is there a reason you insist on ES?

If you have a clean Raspbian and a clean minetest checkout and just do cmake . && make in the main minetest dir it works like a charm here. Provided you install all the correct dev packages of course.

See here for how I did it.

[wziard]

You didn't set RUN_IN_PLACE in cmake. So minetest looks for it's files in the $HOME/.minetest folder (or in /usr/local/share/minetest IRRC?) But they don't go there automatically.

You have 2 options: either run 'sudo make install' to let the makefile copy the files a standard location somewhere under /usr/ or if you don't want to 'pollute' your system just create the $HOME/.minetest folder and symlink the games and mods folder over there.

Oh, another possibilty is that you didn't checkout the minetest_game files? If you get the source form git you only get the engine, and not the minetest_game files, you need to dowload those separately.
