This is a simple guide how to build Minetest for android on Ubuntu <b>on a 64 bit system</b>. It's mostly about preparation, as, once everything is set up, minetest only needs <code>cd build/android && make</code> to compile.
 
  
−
=== Required Packages ===
+
See https://github.com/minetest/minetest/blob/master/doc/README.android
−
Git and make are neccessary: <br\><br/>
 
−
<code>
 
−
sudo apt-get update<br/>
 
−
sudo apt-get install make subversion git-core build-essential<br/><br/>
 
−
</code>
 
−
As your architecture is 64 bit, you need additional packages:<br/><br/>
 
−
<code>
 
−
sudo apt-get install --force-yes libgd2-xpm ia32-libs ia32-libs-multiarch
 
−
</code>
 
−
 
 
−
=== Getting sdk and ndk ===
 
−
<code>
 
−
wget https://dl.google.com/android/android-sdk_r24.0.1-linux.tgz -O android-sdk.tgz <br\>
 
−
wget https://dl.google.com/android/ndk/android-ndk-r9d-linux-x86_64.tar.bz2 -O android-ndk.tar.bz2 <br\>
 
−
tar xf android-sdk.tgz <br\>
 
−
tar xf android-ndk.tar.bz2 <br\>
 
−
android-sdk-linux/tools/android update sdk --no-ui -a --filter platform-tool,android-10,build-tools-21.1.2 <br\><br/>
 
−
</code>
 
−
The last line will ask for your confirmation multiple times.
 
−
 
 
−
=== Obtaining and building minetest ===
 
−
Clone minetest, and build it:<br/><br/>
 
−
<code>
 
−
git clone --depth 1 https://github.com/minetest/minetest.git <br\>
 
−
cd minetest/build/android <br\>
 
−
make <br\>
 
−
</code>

=== Building ===

What you need:
 
−
* GNU/Linux
 
−
* Android NDK
 
−
* Standalone toolchain made with Android NDK (with <code>android_native_app_glue.h</code> copied into <code><TOOLCHAIN_ROOT>/sysroot/usr/include</code>)
 
−
:* '''You need to use Clang''' as GCC produces broken code
 
−
* Android SDK
 
−
* Android device
 
−
* Git
 
−
* CMake
 
−
* Ant
 
−
* ''ADB (optional but very useful)''
 
−
 
 
−
==== Irrlicht ====
 
−
 
 
−
Clone <code>https://github.com/sfan5/irrlicht-android</code>.
 
−
 
 
−
Make sure you have arm-linux-androideabi-gcc ''(It's ok to use gcc for Irrlicht)'' and arm-linux-androideabi-g++ usable and run <code>make</code> in <code>source/Irrlicht</code>.
 
−
 
 
−
This will build Irrlicht as static and shared library and place it in <code>lib/Linux</code>
 
−
 
 
−
==== Minetest ====
 
−
 
 
−
Clone <code>https://github.com/sfan5/minetest</code> and switch to the <code>android_new</code> branch.
 
−
Configure it using CMake like this:
 
−
<pre>
 
−
$ cmake . \
 
−
    -DCMAKE_C_COMPILER=`which arm-linux-androideabi-clang` \
 
−
    -DCMAKE_CXX_COMPILER=`which arm-linux-androideabi-clang++` \
 
−
    -DCMAKE_FIND_ROOT_PATH=<sysroot of your android toolchain> \
 
−
    -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY \
 
−
    -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY \
 
−
    -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=BOTH \
 
−
    -DCMAKE_SYSTEM_NAME=Linux \
 
−
    -DIRRLICHT_LIBRARY=<path to libIrrlicht.a> \
 
−
    -DIRRLICHT_INCLUDE_DIR=<path to include/ of Irrlicht> \
 
−
    -DANDROID=1 \
 
−
    -DANDROID_SUPPORT_LIBRARY=<path to libandroid_support.a> \
 
−
    -DANDROID_SUPPORT_INCLUDE_DIR=<patch to <NDK_DIR>/source/android/support/include> \
 
−
    -DRUN_IN_PLACE=1
 
−
</pre>
 
−
Now just enter <code>make package</code>.
 
−
After make is done go into the <code>Android</code> directory and run <code><SDK_DIR>/tools/android update project --path .</code>.
 
−
 
 
−
Then copy the .so using <code><NDK_DIR>/ndk-build</code> and build the apk using <code>ant debug</code>.
 
−
 
 
−
You will then have the resources in minetest-''x.x.x''.tar.gz and the apk at <code>Android/bin/Minetest-debug.apk</code>.
 
−
You will only need to do the “Android update project” step once.
 
−
 
 
−
=== Running ===
 
−
 
 
−
For this step you need '''minetest-''x.x.x''.tar.gz''' and '''Minetest-debug.apk''' from the previous step.
 
−
 
 
−
Put all resource files & folders (builtin, client, ...) into <code>/sdcard/minetest</code> on your Android device.
 
−
Install <code>Minetest-debug.apk</code>.
 
−
 
 
−
Now touch the Minetest icon and the lovely main menu should appear.

== Development notes ==

−
=== General notes ===
 
−
 
 
−
* cURL does not work
 
−
:* TLS support is needed too
 
−
::* Idea: Use GnuTLS or LibreSSL, because OpenSSL is a nightmare to cross-compile
 
−
* Add Bluetooth support for local multiplayer (maybe)
 
−
:* see (http://people.csail.mit.edu/albert/bluez-intro/x559.html or http://people.csail.mit.edu/albert/bluez-intro/x502.html) and https://github.com/sfan5/minetest/tree/bluetooth
 
−
* OpenAL with Android support: https://github.com/AerialX/openal-soft-android
 
−
 
 
−
=== Getting stuff to work without libCrystax ===
 
−
 
 
−
* Frequently crashes after going through <code>std::ios_base::~ios_base()</code>
 
−
:* Probably related to removal of libCrystax
 
−
* Pressing a button now roughly equals taking away a wood piece of a unstable Jenga tower
 
−
* Options:
 
−
:* Use libc++
 
−
::* Currently a problem with includes
 
−
:* avoid destructing any streams
 
−
::* This is not a good idea
 
−
:* Go back to Crystax toolchain
 
−
::* Uhh… no!
