Nix-env make openssl dev available to cargo install

beeb · February 12, 2023, 12:33pm

Hey! I’m very new to nix and I’m trying to understand how it works.

I’m using the nix-env command as a package manager on macOS Ventura (intel cpu), because I don’t really like homebrew.

I’m trying to install cargo-outdated via cargo install --locked cargo-outdated, which requires that openssl dev is available.

So I did the following:

$ nix-env -iA nixpkgs.openssl.dev # (I also tried nixpkgs.openssl)
$ nix-env -iA nixpkgs.pkg-config

However, the install fails with:

run pkg_config fail: "`\"pkg-config\" \"--libs\" \"--cflags\" \"openssl\"` did not exit successfully: exit status: 1\nerror: could not find system library 'openssl' required by the 'openssl-sys' crate\n\n--- stderr\nPackage openssl was not found in the pkg-config search path.\nPerhaps you should add the directory containing `openssl.pc'\nto the PKG_CONFIG_PATH environment variable\nNo package 'openssl' found\n"

This is the same error I get if I run: pkg-config --libs --cflags openssl. But pkg-config is installed correctly:

$ which pkg-config
/Users/beeb/.nix-profile/bin/pkg-config

And when I do echo $PKG_CONFIG_PATH, the environment variable is empty.

How can I have pkg-config report the correct path for openssl so that cargo can build the openssl-sys crate?

Any help would be greatly appreciated! Thanks

Why not just nix-env -iA nixpkgs.cargo-outdated it?

For compiling you have to use nix-shell like this: nix-shell -p openssl pkg-config.

Thanks for the reply! I prefer to have my cargo tools installed with cargo (same ecosystem) and sometimes the latest version is not available in the nix repo. Also, this problem happens with all my dependencies that require openssl, even when they are not in nixpkgs.

When doing nix-shell -p openssl pkg-config followed by cargo install ... I get a long list of errors, all of them look like this:

error: could not compile `libz-sys` due to previous error
error: could not compile `curl-sys` due to previous error
error: linking with `cc` failed: exit status: 1

Is there any useful information I could gather from the nix package definition for cargo-outdated ? Some other package I’m missing or something? I see mention of:

CoreFoundation
Security
SystemConfiguration

in the unstable version. Not sure how to get or activate those.

beeb · February 13, 2023, 7:05am

Adding libiconv fixed the linker errors but gave me others:

cargo:warning=libgit2/src/streams/stransport.c:13:10: fatal error: 'Security/SecureTransport.h' file not found
  cargo:warning=#include <Security/SecureTransport.h>
  cargo:warning=         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

beeb · February 13, 2023, 7:40am

Okay I give up, will install with nix-env -iA nixpkgs.cargo-outdated

Apologies for the necro, but this was the first search result for me so figured I’d leave my solution.

This can be resolved by adding ~/.nix-profile/lib/pkgconfig to the PKG_CONFIG_PATH.

My home-manager module looks like this:

{ pkgs, ... }: { 
    home.packages = [ pkgs.pkg-config ];
    programs.zsh = {
        initExtra = ''
          export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$HOME/.nix-profile/lib/pkgconfig
         '';
    };
}

using the nix shell is probably a more correct way of doing things long-term, but I’m not all-in on using nix for everything just yet.
