为Android (Flutter)构建Rust项目时出错:arm-linux-androideabi-ranlib无法

Question

我正在做一个使用Flutter和Rust的项目，我正在尝试为Android构建它。然而，我面临着一个与arm-linux-androideabi-ranlib没有找到相关的错误。下面是我得到的错误信息:

--- stderr

我已经检查了NDK目录，似乎所需的工具都存在，但不完全是文件arm-linux-androideabi-ranlib。下面是工具链目录的ls输出:

我使用Flutter 3.7.6, Dart 2.19.3和cargo-ndk。我的它。属性文件将ANDROID_NDK变量设置为正确的路径:

ANDROID_NDK=/home/user/Android/Sdk/ndk/25.2.9519653/

在我的build.gradle中，我有以下任务来构建Rust项目:

[
new Tuple2('Debug', ''),
new Tuple2('Profile', '--release'),
new Tuple2('Release', '--release')
].each {
def taskPostfix = it.first
def profileMode = it.second
tasks.whenTaskAdded { task ->
if (task.name == "javaPreCompile$taskPostfix") {
task.dependsOn "cargoBuild$taskPostfix"
}
}
tasks.register("cargoBuild$taskPostfix", Exec) {
commandLine 'sh', '-c', """cd ../../rust/my_lib  && 
ANDROID_NDK_HOME="$ANDROID_NDK" cargo ndk 
-t armeabi-v7a -t arm64-v8a -t x86 -t x86_64 
-o ../android/app/src/main/jniLibs build $profileMode"""
}
}

我在我的项目中使用flutter_rust_bridge版本1.67.0。关于build.gradle文件的文档在这里。

RustCargo.toml:

[lib]
crate-type = ["lib", "staticlib", "cdylib"]
[dependencies]
openssl = { version = "0.10", features = ["vendored"] }

有没有人知道为什么构建失败的"arm-linux-androideabi-ranlib not found&;错误和如何修复它?任何帮助都会很感激。谢谢!

您可以通过CC_aarch64-linux-android、RANLIB_aarch64-linux-android等环境变量配置OpenSSL Android构建脚本使用的命令路径。下面是我用来配置这些变量的PowerShell脚本:

$ANDROID_HOME = "/path/to/Android/sdk";
$ANDROID_SUBDIRS = "emulator", "tools", "tools/bin", "platform-tools";
ForEach ($subdir in $ANDROID_SUBDIRS) {
${env:PATH} = "${env:PATH}:${ANDROID_HOME}/$subdir";
}
${env:ANDROID_HOME} = $ANDROID_HOME;
${env:ANDROID_SDK_ROOT} = $ANDROID_HOME;
${env:ANDROID_NDK_ROOT} = "$ANDROID_HOME/ndk/25.2.9519653";
function configureAndroidToolchain {
# "windows-x86_64" on Windows
# "darwin-x86_64" on macOS (even with Apple Silicon)
# "linux-x86_64" on Linux
$hostTag = "darwin-x86_64";
# Use the minSdkVersion you use
$sdkVersion = "29";
$archs = @{}
$archs["aarch64-linux-android"] = $null;
$archs["armv7-linux-androideabi"] = "armv7a-linux-androideabi";
$archs["x86_64-linux-android"] = $null;
$archs["i686-linux-android"] = $null;
$prebuiltDir = "${env:ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/$hostTag/bin";
foreach ($rustArch in $archs.Keys) {
$androidArch = $archs[$rustArch];
if ($androidArch -eq $null) {
$androidArch = $rustArch;
}
Set-Item "env:CC_$rustArch" -Value "$prebuiltDir/$androidArch$sdkVersion-clang";
Set-Item "env:CXX_$rustArch" -Value "$prebuiltDir/$androidArch$sdkVersion-clang++";
Set-Item "env:AR_$rustArch" -Value "$prebuiltDir/llvm-ar";
Set-Item "env:RANLIB_$rustArch" -Value "$prebuiltDir/llvm-ranlib";
Set-Item "env:CFLAGS_$rustArch" -Value "-D__ANDROID_MIN_SDK_VERSION__=$sdkVersion";
Set-Item "env:CXXFLAGS_$rustArch" -Value "-D__ANDROID_MIN_SDK_VERSION__=$sdkVersion";
}
}
configureAndroidToolchain;

使用这些变量后，OpenSSL构建将正常完成。

我遇到了这个类似的错误，我正在运行最新版本的Android Studio，并使用它安装了NDK。它安装了$HOME/Android/Sdk中的所有内容。我是这样解决的:

首先你需要设置这些环境:

export ANDROID_HOME=$HOME/Android/Sdk
export ANDROID_NDK_HOME=$HOME/Android/Sdk/ndk/25.2.9519653
export TOOLCHAIN=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64
export TARGET=aarch64-linux-android
export API=33
export AR=$TOOLCHAIN/bin/llvm-ar
export CC=$TOOLCHAIN/bin/$TARGET$API-clang
export AS=$CC
export CXX=$TOOLCHAIN/bin/$TARGET$API-clang++
export LD=$TOOLCHAIN/bin/ld
export RANLIB=$TOOLCHAIN/bin/llvm-ranlib
export STRIP=$TOOLCHAIN/bin/llvm-strip
export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin
export PATH=$PATH:$TOOLCHAIN/bin

之后，在$HOME/.cargo/config中添加如下内容(如果配置文件不存在，则创建配置文件):

[target.aarch64-linux-android]
linker = "/<absolute path to home>/Android/Sdk/ndk/25.2.9519653/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android33-clang"

之后，运行cargo build --target aarch64-linux-android或使用./gradlew build应该工作。

尝试使用"openssl-src"版本低于或等于"111.24.0+1.1.1 "我在cargo .lock

中每次货物更新后手动设置它

[[package]]
name = "openssl-src"
version = "111.24.0+1.1.1s"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "3498f259dab01178c6228c6b00dcef0ed2a2d5e20d648c017861227773ea4abd"
dependencies = [
"cc",
]
