Support building for Android using NDK The easiest way to use the NDK in conjunction with this Makefile (tested on linux-x86_64): 1. Download the latest NDK (r21d) from Google from https://developer.android.com/ndk/downloads 2. Place and unzip the NDK in $HOME/ndk folder 3. Export the path variable e.g., `export PATH=$PATH:$HOME/ndk/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/bin` 4. cd to your Stockfish/src dir 5. Issue `make -j ARCH=armv8 COMP=ndk build` (use `ARCH=armv7` or `ARCH=armv7-neon` for older CPUs) 6. Optionally `make -j ARCH=armv8 COMP=ndk strip` 7. That's all. Enjoy! Improves support from Raspberry Pi (incomplete?) and compiling on arm in general closes https://github.com/official-stockfish/Stockfish/pull/3015 fixes https://github.com/official-stockfish/Stockfish/issues/2860 fixes https://github.com/official-stockfish/Stockfish/issues/2641 Support is still fragile as we're missing CI on these targets. Nevertheless tested with: ```bash # build crosses from ubuntu 20.04 on x86 to various arch/OS combos # tested with suitable packages installed # (build-essentials, mingw-w64, g++-arm-linux-gnueabihf, NDK (r21d) from google) # cross to Android export PATH=$HOME/ndk/android-ndk-r21d/toolchains/llvm/prebuilt/linux-x86_64/bin:$PATH make clean && make -j build ARCH=armv7 COMP=ndk && make -j build ARCH=armv7 COMP=ndk strip make clean && make -j build ARCH=armv7-neon COMP=ndk && make -j build ARCH=armv7-neon COMP=ndk strip make clean && make -j build ARCH=armv8 COMP=ndk && make -j build ARCH=armv8 COMP=ndk strip # cross to Raspberry Pi make clean && make -j build ARCH=armv7 COMP=gcc COMPILER=arm-linux-gnueabihf-g++ make clean && make -j build ARCH=armv7-neon COMP=gcc COMPILER=arm-linux-gnueabihf-g++ # cross to Windows make clean && make -j build ARCH=x86-64-modern COMP=mingw ``` No functional change
