交叉编译Android时出现链接器错误 [英] linker errror while cross compiling for Android
本文介绍了交叉编译Android时出现链接器错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想为Android交叉编译我的项目。我已经创建了~/.Cargo/配置，如下所示：-
[target.armv7-linux-androideabi]
ar = "/optHDD/AndroidNDK/toolchains/llvm/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ar"
linker = "/optHDD/AndroidNDK/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi26-clang"
以下是我的项目的Cargo.toml文件：-
[package]
name = "examer"
version = "0.1.0"
authors = ["none"]
edition = "2018"
[dependencies]
tokio = { version = "0.2", features = ["full"] }
lazy_static = "1"
clap = "2.*"
futures = { version = "0.3", default-features = false, features = ["alloc"] }
futures-util = "0.3"
async-tungstenite = { version = "*", features= ["tokio-runtime"] }
mongodb = { version = "1.*", features = ["tokio-runtime"] }
pbkdf2 = "0.2"
# serde = { version = "1.0", features = ["derive", "rc"] }
serde_cbor = "0.11"
derive_builder = "0.9.0"
# serde_derive = "1.0"
[dev-dependencies]
tungstenite = "0.11"
url = "2"
[lib]
name = "libexamer"
path = "src/lib.rs"
[[bin]]
name = "examer"
path = "src/main.rs"
它在桌面Linux上编译和运行良好
但它不能为Android Linux编译。我已经添加了目标ARMv7-linux-androideabi和rustup

Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the `OPENSSL_DIR` environment variable for the
compilation process.
Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.
If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.

在谷歌上搜索后，我发现人们建议手动设置AR和CC环境变量，所以我也这样做了

推荐答案
我已临时解决，方法是在我的货物中添加以下内容
[target.armv7-linux-androideabi.dependencies]
openssl = { version = "*", features = ["vendored"] }
features = ["vendored"]为我静态构建OpenSSL。
这篇关于交叉编译Android时出现链接器错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
