cargo编译musl报错openssl
背景
生产环境和编译环境的glibc版本不同出现来如下报错
/lib64/libc.so.6: version `GLIBC_x.xx' not found
所以需要使用cargo 跨平台编译x86_64-unknown-linux-musl，而后就报出来openssl相关的错误：
--- stderr thread 'main' panicked at ' 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. $HOST = x86_64-unknown-linux-gnu $TARGET = x86_64-unknown-linux-musl openssl-sys = 0.9.48
原因
上文总结一句话：编译器没找到ssl的dev包，并给出来debian和red-hat的解决方法。但很可惜，我的编译环境是manjaro，没有libssl_dev类似的包
解决
对于debian/ubuntu就是
apt-get install libssl-dev
对于centos/fedora就是
yum install -y openssl-devel
对于Arch/manjaro，在确保安装openssl情况下
export OPENSSL_DIR=/usr
具体过程通过命令找到libssl.so文件路径(这里是/usr/lib/libsso.so)。编译时会连接OPENSSL_DIR/lib/libssl.so。因此这里的OPENSSL_DIR就是/usr了。
到此，相信大家对“cargo编译musl报错openssl怎么办”有了更深的了解，不妨来实际操作一番吧！这里是本站网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
