linux - 使用 Cargo 构建 openssl crate 的问题

Question

每当我尝试编译我得到

我同时安装了 OpenSSL 和 OpenSSL-1.0。我尝试同时使用 Rust stable 和 nightly。我还尝试包含不同版本的 openssl crate，但我认为 Cargo 只是在构建我认为 grpc 正在使用的 crate 版本。我在使用 Arch Linux。

Answer 1

您的项目正在使用 openssl 0.9.x(可能通过 tls-api-native-tls 0.1.x -> native-tls 0.1.x -> openssl 0.9.x)，不支持 OpenSSL 1.1.1。我也在使用 Arch Linux，我必须将我的程序更新到 openssl 0.10 才能使用 OpenSSL 1.1.1。

在您的情况下，tls-api-native-tls 需要更新以依赖于 native-tls 0.2.x，它使用 openssl 0.10。 x(支持 OpenSSL 1.1.1)。 There is an open issue about this.

如果这太复杂，您还可以使用各种环境变量来告诉 openssl-sys 的构建脚本您要使用哪个 OpenSSL 安装。如果您更喜欢使用 OpenSSL 1.0.x，请在您的 shell 中输入以下命令:

$ cargo clean
$ OPENSSL_INCLUDE_DIR=/usr/include/openssl-1.0 OPENSSL_LIB_DIR=/usr/lib/openssl-1.0 cargo build

(注意:以上路径可能特定于 Arch Linux。)
