openssl - 如何防止通过多个依赖项链接到同一个 native 库？

转载作者：行者123 更新时间：2023-11-29 07:51:28

问题:如何解决(或修复)我的两个依赖项链接到同一个库，但该库不能链接两次的情况？这似乎通常可以通过共享库来解决，但我不确定如何使用 Rust 来解决它。

详细信息:

我正在使用 Nickel framework 在 Rust 中制作一个网络应用程序和 rust-postgres对于数据库。构建时出现以下错误:

> cargo build
native library `openssl` is being linked to by more than one package, and can only be linked to by one package

  openssl-sys v0.3.3 (https://github.com/sfackler/rust-openssl.git#ee66da60)
  openssl-sys v0.3.3

通过 Cargo.lock 查看，openssl 被 http(它是 nickel 的依赖项)和 rust-postgres 引用。

我的 Cargo.toml 看起来像这样:

[package]

name = "goodoldweb"
version = "0.0.1"
authors = ["..."]

[dependencies.nickel]
git="https://github.com/nickel-org/nickel.rs.git"

[dependencies.postgres]
git="https://github.com/sfackler/rust-postgres.git"

这是完整的 Cargo.lock:

最佳答案

罪魁祸首似乎是nickel-org's rust-http (这是 nickel 的依赖项)引入了 sfackler/rust-openssl 而不是 crates.io 上的“官方”openssl。不幸的是，rust-http 存储库没有启用问题，但我在 nickel 的主要存储库上打开了一个:#139
