# termux-ndk **Repository Path**: bnyg/termux-ndk ## Basic Information - **Project Name**: termux-ndk - **Description**: https://github.com/Lzhiyong/termux-ndk导入 - **Primary Language**: Unknown - **License**: Not specified - **Default Branch**: master - **Homepage**: None - **GVP Project**: No ## Statistics - **Stars**: 3 - **Forks**: 1 - **Created**: 2020-11-12 - **Last Updated**: 2024-07-06 ## Categories & Tags **Categories**: Uncategorized **Tags**: None ## README This is Google's standard NDK, which only supports running on android devices with aarch64 architecture the source code from AOSP llvm-toolchain master branch, because llvm is cross-platform, so we can recompile it to Android At first, we don‘t need to rebuild the whole NDK, since google already built most of it. we only need to build llvm toolchain, then replace the llvm in the NDK. of course you can build the whole NDK, use checkbuild.py, but the source code is too huge. ##### [download r21](https://github.com/Lzhiyong/termux-ndk/releases) #### How to build Termux needs to install aarch64 version of Linux, I recommend using [TermuxArch](https://github.com/SDRausty/TermuxArch) ArchLinux only downloads source code, we are not using it to compile For more details, please refer to toolchain build doc The latest version of this document is available at [Toolchains.md](https://android.googlesource.com/platform/ndk/+/master/docs/Toolchains.md) and [ToolchainPrebuilts.md](https://android.googlesource.com/platform/external/clang/+/dev/ToolchainPrebuilts.md) ```bash # I assume that you have installed the ArchLinux # install repo pacman -S repo cd /data/data/com.termux/files/home mkdir llvm-toolchain && cd llvm-toolchain # download the source code repo init -u https://android.googlesource.com/platform/manifest -b llvm-toolchain # for china repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b llvm-toolchain repo sync -c -j4 # sync finish, exit ArchLinux exit ``` **** Termux needs to install some build-essential packages, then copy or soft link it to llvm-toolchain/prebuilts ```bash # remove prebuilt clang under llvm-toolchain/prebuilts, CLANG_PREBUILT_VERSION is defined in llvm-toolchain/toolchain/llvm_android/constants.py rm -vrf llvm-toolchain/prebuilts/clang/host/linux-x86/CLANG_PREBUILT_VERSION/* # extract android-ndk-r21.tar.xz to your path # android-ndk-r21.tar.xz from termux-ndk release tar -xJvf android-ndk-r21.tar.xz -C /path/to/android-ndk-r21 # copy ndk llvm toolchain to prebuilt clang directory cp -r android-ndk-r21/toolchains/llvm/prebuilt/linux-aarch64/* llvm-toolchain/prebuilts/clang/host/linux-x86/CLANG_PREBUILT_VERSION # soft link cmake to llvm-toolchain/prebuilts ln -sf /data/data/com.termux/files/usr/bin/cmake llvm-toolchain/prebuilts/cmake/linux-x86/bin/cmake # soft link ninja to llvm-toolchain/prebuilts ln -sf /data/data/com.termux/files/usr/bin/ninja llvm-toolchain/prebuilts/ninja/linux-x86/bin/ninja # remove prebuilt python under llvm-toolchain/prebuilts rm -vrf llvm-toolchain/prebuilts/python/linux-x86/* # apt download python3 # extract /data/data/com.termux/files/usr/var/cache/apt/archives/python_3.8.2_aarch64.deb to llvm-toolchain/prebuilts/python/linux-x86 # or modify llvm-toolchain/toolchain/llvm_android/py3_utils.py # golang is the same # copy libedit to libedit prebuilt dirctory cp /data/data/com.termux/files/usr/lib/libedit* llvm-toolchain/prebuilts/libedit/linux-x86/lib # copy swig to swig prebuilt directory cp /data/data/com.termux/files/usr/bin/swig llvm-toolchain/prebuilts/swig/linux-x86/bin # modify llvm-toolchain/toolchain/llvm_android/configs.py # change sysroot to llvm-toolchain/prebuilts/clang/host/linux-x86/CLANG_PREBUILT_VERSION/sysroot # There are some that need to be change, please see llvm_android/*.py for details ``` **** ### OK start compile now! ```bash # no build for windows python toolchain/llvm_android/build.py --no-build windows ``` **** #### Building binutils ```bash # execute python toolchain/binutils/build.py # or you can compile it manually # host is aarch64-linux-android # target: arm-linux-androideabi # aarch64-linux-android # i686-linux-android # x86_64-linux-android cd binutils && mkdir build && cd build # setting android ndk toolchain TOOLCHAIN=/path/to/android-ndk-r21/toolchains/llvm/prebuilt/linux-aarch64 ../configure \ CC=$TOOLCHAIN/bin/aarch64-linux-android29-clang \ CXX=$TOOLCHAIN/bin/aarch64-linux-android29-clang++ \ CFLAGS="-fPIC -std=c11" \ CXXFLAGS="-fPIC -std=c++17" \ --prefix=$HOME/binutils/x86_64 \ --host=aarch64-linux-android \ --target=x86_64-linux-android \ --enable-initfini-array \ --enable-plugins \ --enable-gold \ --enable-lto \ --enable-libada \ --enable-liboffloadmic=target \ --enable-libssp \ --enable-threads \ --enable-new-dtags ``` **** #### Simpleperf no need to compile ```bash cd android-ndk-r21/simpleperf/bin/linux/aarch64 ln -sf ../../android/arm64/simpleperf ./simpleperf ``` **** #### Building shader-tools ```bash cd /data/data/com.termux/files/home git clone https://github.com/google/shaderc cd shaderc/third_party git clone https://github.com/KhronosGroup/SPIRV-Tools.git spirv-tools git clone https://github.com/KhronosGroup/SPIRV-Headers.git spirv-tools/external/spirv-headers git clone https://github.com/google/googletest.git git clone https://github.com/google/effcee.git git clone https://github.com/google/re2.git git clone https://github.com/KhronosGroup/glslang.git # start building shaderc... cd ~/shaderc && mkdir build && cd build # setting android ndk toolchain TOOLCHAIN=/path/to/android-ndk-r21/toolchains/llvm/prebuilt/linux-aarch64 cmake -G "Ninja" \ -DCMAKE_C_COMPILER=$TOOLCHAIN/bin/aarch64-linux-android29-clang \ -DCMAKE_CXX_COMPILER=$TOOLCHAIN/bin/aarch64-linux-android29-clang++ \ -DCMAKE_SYSROOT=$TOOLCHAIN/sysroot \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=/path/to/shader-tools \ .. ninja install -j16 ``` **** #### Building renderscript (llvm-rs-cc and bcc_compat) build bcc_compat and llvm-rs-cc need older version llvm and clang, download [llvm.tar.xz](https://github.com/Lzhiyong/termux-ndk/releases) or you can download the llvm source code to compile it if you don't want to compile liblog, change to ```bash # slang source code # git clone https://android.googlesource.com/platform/frameworks/compile/slang # libbcc source code # git clone https://android.googlesource.com/platform/frameworks/compile/libbcc # rs souce code # git clone https://android.googlesource.com/platform/frameworks/rs # llvm and clang source code # git clone https://android.googlesource.com/platform/external/llvm # git clone https://android.googlesource.com/platform/external/clang # clone termux-ndk git clone https://github.com/Lzhiyong/termux-ndk.git # extract llvm.tar.xz to termux-ndk/renderscript # llvm.tar.xz from termux-ndk release tar -xJvf llvm.tar.xz -C renderscript # build llvm-rs-cc cd renderscript/slang/build ./build.sh # build bcc_compat cd renderscript/libbcc/build ./build.sh ``` **** #### Building finish! llvm-toolchain stage1 and stage2 compilation takes about 10 hours. If your phone performance is good, the time may be shorter, but it still takes a lot of time to compile. There may be some errors during the compilation process, please solve it yourself! **** #### Screenshots #### Buinding app with ndk cmake Using termux to build android app. 1\. download the build-essential toolchain, [gradle](https://gradle.org) and [openjdk](https://github.com/Lzhiyong/termux-ndk/releases), update [aapt2](https://github.com/Lzhiyong/sdk-tools) is here. 2\. please note when you execute the gradle build command finish, some errors will occur. > AAPT2 aapt2-4.0.1-6197926-linux Daemon #7: Daemon startup failed. This should not happen under normal circumstances, please file an issue if it does. 3\. this is because the gradle plugin will download a corresponding version of aapt2. 4\. We need to replace the aapt2-xxx-linux.jar, which under /data/data/com.termux/files/home/.gradle 5\. execute the find command to search for aapt2, find . -type f -name "aapt2\*-linux.jar" (such as aapt2-4.0.1-6197926-linux.jar or other version) 6\. extract the jar file, aapt2 is inside this jar file, replace it with [sdk-tools](https://github.com/Lzhiyong/sdk-tools)/build-tools/aapt2 7\. if there are still errors, continue to replace！ ```bash # modify local.properties file # sdk.dir=/path/to/android-sdk # ndk.dir=/path/to/ndk # cmake.dir=/path/to/cmake # setting the buildToolsVersion # update buildToolsVersion you need download the sdk-tools, then copy it to android-sdk/build-tools platform-tools # sdk-tools from https://github.com/Lzhiyong/sdk-tools buildToolsVersion "30.0.1" # setting the cmake version # update cmake you need download the cmake source code to compile it ...... externalNativeBuild { cmake { // specify the cmake version version "3.17.2" arguments "-DANDROID_APP_PLATFORM=android-21", "-DANDROID_STL=c++_static", "-fuse-ld=lld" abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64' } } ...... # building examples cd termux-ndk/cmake-example gradle build ``` ## Issues Every NDK version has a lot of changes, direct compilation will fail, the build script are not generic, so please solve the error yourself. llvm-rs-cc may have bugs, I rewrote the rs_cc_options.cpp file. because RSCCOptions.inc compilation error, I can't solve it yet. RSCCOptions.inc is generated by llvm-tblgen, but which has errors llvm-tblgen -I=../llvm/include RSCCOptions.tb -o RSCCOptions.inc if anyone konws, please submit to issue
