最近我一直在为ARM编译一个Rust项目。它可以完美地编译x86,但是每当我切换到ARM目标时,它就无法找到Openssl安装,我已经安装并使用了pkg-config,所以不是那个错误。也不确定如何成功设置OPENSSL_DIR变量或在哪里找到安装文件。完整的错误信息如下:
error: failed to run custom build command for `openssl-sys v0.9.61`
Caused by:

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.

.cargo配置文件如下:
[build]
target-dir="/home/bob/yagna/blueberry"
target="armv7-unknown-linux-gnueabihf"
linker = "arm-linux-gnueabihf-gcc"
[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"
我不知道该怎么做,我的Ubuntu已经安装并更新了libssl-dev,目标是使用rustup和sudo apt-get进行添加和安装。不确定如何解决这个问题。
libssl-dev
。 - undefinedopenssl = { version = "0.10", features = ["vendored"] }
就可以实现这个功能。 - undefined
