This page is about the WIP Android port by sfan5, not about the official port

Building and Running

Building

What you need:

  • GNU/Linux
  • Android NDK
  • Standalone toolchain made with Android NDK (with android_native_app_glue.h copied into <TOOLCHAIN_ROOT>/sysroot/usr/include)
  • You need to use Clang as GCC produces broken code
  • Android SDK
  • Android device
  • Git
  • CMake
  • Ant
  • ADB (optional but very useful)

Irrlicht

Clone https://github.com/sfan5/irrlicht-android.

Make sure you have arm-linux-androideabi-gcc (It's ok to use gcc for Irrlicht) and arm-linux-androideabi-g++ usable and run make in source/Irrlicht.

This will build Irrlicht as static and shared library and place it in lib/Linux

Minetest

Clone https://github.com/sfan5/minetest and switch to the android_new branch. Configure it using CMake like this:

$ 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

Now just enter make package. After make is done go into the Android directory and run <SDK_DIR>/tools/android update project --path ..

Then copy the .so using <NDK_DIR>/ndk-build and build the apk using ant debug.

You will then have the resources in minetest-x.x.x.tar.gz and the apk at Android/bin/Minetest-debug.apk. 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 /sdcard/minetest on your Android device. Install Minetest-debug.apk.

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)

Getting stuff to work without libCrystax

  • Frequently crashes after going through std::ios_base::~ios_base()
  • 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!
