官方编译环境配置地址:https://mozilla.github.io/firefox-browser-architecture/experiments/2017-09-21-rust-on-android.html
1、安装Android ndk环境
2、配置ndk 到path中
export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export NDK_HOME=$ANDROID_HOME/ndk-bundle
3、安装rust环境,如果有可以跳过
curl https://sh.rustup.rs -sSf | sh
4、生成交叉编译的文件
$符号是命令行中自带的符号,不需要复杂
$ mkdir NDK
$ cd NDK
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch arm64 --install-dir NDK/arm64
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch arm --install-dir NDK/arm
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch x86 --install-dir NDK/x86
5、然后可以直接切换到 .cargo 的目录下,直接创建一个config文件,并添加编译配置
cd ~/.cargo
open ./
然后创建一个文本文件。复制一下信息并保存.
[target.aarch64-linux-android]
ar = "<上边NDK的实际路径>/NDK/arm64/bin/aarch64-linux-android-ar"
linker = "<上边NDK的实际路径>/NDK/arm64/bin/aarch64-linux-android-clang"
[target.armv7-linux-androideabi]
ar = "<上边NDK的实际路径>/NDK/arm/bin/arm-linux-androideabi-ar"
linker = "<上边NDK的实际路径>/NDK/arm/bin/arm-linux-androideabi-clang"
[target.i686-linux-android]
ar = "<上边NDK的实际路径>/NDK/x86/bin/i686-linux-android-ar"
linker = "<上边NDK的实际路径>/NDK/x86/bin/i686-linux-android-clang"
然后保存config文件。
6、添加Android架构到rustup中,以便在交叉编译时使用:
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android
7、然后可以通过cargo创建项目,添加配置即可。
8、最后执行编译命令即可
以下三个命令是生成不同系统架构的动态链接库的命令,按需要使用即可
cargo build --target aarch64-linux-android --release
cargo build --target armv7-linux-androideabi --release
cargo build --target i686-linux-android --release
9、编译过程中出现的问题
error: linking with `/Users/chenpengfei/Desktop/rust_work/NDK/arm64/bin/aarch64-linux-android-clang` failed: exit status: 1

clang90: error: linker command failed with exit code 1 (use -v to see invocation)
error: could not compile `rust` due to previous error
经过调试,发现是因为Mac电脑上无法安装lunwind 导致,然后使用brew进行安装,但是依然失败。
出现以下异常:
libunwind: Linux is required for this software.
后续使用其他电脑进行测试。
