Android ndk for termux, that only support aarch64 architecture
The source code from AOSP llvm-toolchain, which is consistent with the official Ndk version
At first, we don‘t need to rebuild the whole Ndk, since google already built most of it. so we only need to build the llvm toolchain, then replace the llvm inside Ndk.
For more details information, please refer to toolchain readme docs
download r23
How to build
Termux needs to install aarch64 version of Linux to download the source code, we are not using it to compile
In order to save storage , there are some prebuilts tools that do not need to be downloaded. comment out them in the llvm-toolchain/.repo/manifests/default.xml file, click here for example.
pkg install proot-distro
proot-distro install archlinux
# 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
# rebuild the toolchain with that manifest
cp /path/to/android/android-ndk-r23/toolchains/llvm/prebuilt/linux-x86_64/manifest_7284624.xml .repo/manifests
repo init -m manifest_7284624.xml
repo sync -c -j4
# sync finish, exit ArchLinux
exit
Install some build-essential packages, then copy or soft link it to llvm-toolchain/prebuilts
I recommend compiling on PC, because compiling on device will take a long time
If compiling on PC, we only replece the prebuilt clang toolchain
# remove clang-bootstrap
rm -vrf llvm-toolchain/prebuilts/clang/host/linux-x86/clang-bootstrap
# extract android-ndk-r23.tar.xz to /path/to/clang-bootstrap
tar -xJvf android-ndk-r23.tar.xz -C llvm-toolchain/prebuilts/clang/host/linux-x86/clang-bootstrap
# 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 make to llvm-toolchain/prebuilts
ln -sf /data/data/com.termux/files/usr/bin/make llvm-toolchain/prebuilts/build-tools/linux-x86/bin/make
# soft link ninja to llvm-toolchain/prebuilts
ln -sf /data/data/com.termux/files/usr/bin/ninja llvm-toolchain/prebuilts/build-tools/linux-x86/bin/ninja
# remove prebuilt python
rm -vrf llvm-toolchain/prebuilts/python/linux-x86/*
# apt download python3
# extract python_3.9.x_aarch64.deb to llvm-toolchain/prebuilts/python/linux-x86
# building golang
apt install golang
cd llvm-toolchain/prebuilts/go/linux-x86/src
./make.bash
Building start!
# no build for windows
# If it is not the first time to build, you can add options --skip-source-setup to save time
python toolchain/llvm_android/build.py --no-build windows --skip-source-setupllvm-toolchain stage1 and stage2 compilation will take a long time.
there may be some errors during the compilation process, please solve it by yourself!
Building finish!

FAQ
- I don't compile the Linux-aarch64 version only for Android.
- Termux now has many packages, including
Openjdk-17GradleKotlinand so on.
so in most cases we don't need to use proot linux.
