急切寻求rust编译问题帮助(archlinux, openssl)

拉取了rustbuster的v3.0.3版本文件, 二进制文件无法使用, 执行结果如下:

[root_cn@archlinux target]$ ./rustbuster-v3.0.3-x86_64-unknown-linux-gnu
./rustbuster-v3.0.3-x86_64-unknown-linux-gnu: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

拉取了main源码, 想自行尝试编译, 然后卡在了openssl, 以下为报错信息:

The following warnings were emitted during compilation:

  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install libssl-dev
      # On Arch Linux
      sudo pacman -S openssl
      # On Fedora
      sudo dnf install openssl-devel

  See rust-openssl README for more information:

      https://github.com/sfackler/rust-openssl#linux

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
warning: build failed, waiting for other jobs to finish...

经过检查openssl与rust均为最新版本,

[root_cn@archlinux target]$ sudo pacman -S rust
[sudo] password for root_cn:

在网上找了一下, 查到资料, 在rust-openssl的issues中提到类似报错, 得到解释如下:

If you are cross compiling to MUSL, you either need to point openssl-sys to the location that you have a copy of OpenSSL cross compiled to MUSL, or tell it to build a copy of OpenSSL itself with the vendored feature.

如果你是交叉编译到MUSL，你需要将openssl-sys指向你有一个交叉编译到MUSL的OpenSSL副本的位置，或者告诉它用vendored特性构建一个OpenSSL本身的副本。

由于不会rust, 依靠关键词"交叉编译"+"cargo"搜索到了cargo交叉编译rust程序, 顺着找到文件:

[root_cn@archlinux .cargo]$ cat ~/.cargo/config
[source.crates-io]
replace-with = 'sjtu' # 指定使用下面哪个源，修改为source.后面的内容即可

# 中国科学技术大学
[source.ustc]
registry = "https://mirrors.ustc.edu.cn/crates.io-index"

# 上海交通大学
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index/"

# 清华大学
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"

# rustcc社区
[source.rustcc]
registry = "https://code.aliyun.com/rustcc/crates.io-index.git"

没有找到交叉编译的设置, 由于本人不会rust, 线索断了, 尝试向大家寻求一波帮助, 非常感谢阅读.

交叉编译需要指定target选项，比如:

# in config.toml
[target.x86_64-unknown-linux-musl]
rustflags = [
    "-C", "linker-flavor=gcc", "-C", "link-self-contained=no",
]
# zig cc -target x86_64-linux-musl
linker = ".cargo/musl-zcc.bat"

问题已经解决, 通过寻找rust-openssl的issues, 得知:

openssl-sys v0.9.53 was released 3 years ago, and does not support your OpenSSL version. Run cargo update.

openssl-sys v0.9.53是3年前发布的，不支持OpenSSL版本。运行cargo update。 感觉报错情况差不多, 参考一下, 在目录下执行以下命令:

[root_cn@archlinux rustbuster]$ pwd
/home/root_cn/rust/rustbuster
[root_cn@archlinux rustbuster]$ cargo update
[root_cn@archlinux rustbuster]$ cargo build

运行成功,顺便找到一行未被使用的函数:
