Setting OPENSSL_DIR how exactly. .

Help

Good day!

I’m trying to contribute to Pijul but I have to install it first. I’ve installed rustup, beta, openssl, clang, pkg-config. Just when I thought I’d finally be able to install it, I was met with this message:

error: failed to run custom build command for `openssl-sys v0.9.58`

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot

  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.

I tried finding something like libssl-dev and openssl-devel for NixOs, but there’s none. I’m really not sure what to do from this point onward because I also don’t know how to set OPENSSL_DIR environment variable. :sweat:

Please advise, I’d really appreciate. Many thanks!

Also wow, the live preview is awesome.

Looks like you’re trying to build Pijul manually.

You should be able to find the openssl dir with which -s openssl. On my system, it shows me this:

which -s openssl
/home/mchrist/.nix-profile/bin/openssl -> /nix/store/wp81dnxgrpi4lgy20r82kfg9nwrmypkm-openssl-1.1.1g-bin/bin/openssl

You could set your OPENSSL_DIR env var to the /nix/store folder.

Another approach would be to build Pijul with Nix. There’s already a package available in Nixpkgs. I imagine you could use something similar and point the source to your local development folder instead of pulling the rust crate, you could use overrideAttrs to adjust just the src attribute of that derivation…

3 
 nix-shell '<nixpkgs>' -A pijul

This should give you a build environment for the currently package pijul in your nixpkgs?.

I’m going about doing it this way and I’ve run into:

thread 'main' panicked at 'OpenSSL include directory does not exist: /nix/store/j7kaa5ja1998wjbnj8rjks7d3574ppy9-openssl-3.0.8-bin/bin/openssl/include', /home/chrisobrien/.cargo/registry/src/github.com-1ecc6299db9ec823/openssl-sys-0.9.87/build/main.rs:86:9

I’m using rust, trying to build a dev branch for a colleague.

You shouldn’t need to set OPENSSL_LIB anymore, adding openssl to buildInputs and pkg-config to nativeBuildInputs in your derivation should work. And if you are using a dev shell, you might also want to set LD_LIBRARY_PATH = lib.makeLibararyPath [ openssl ];

6

Could you elaborate more on this? Do I set this in configuration.nix?

7

In your dev shell preferably

8

I am new to shell.nix or dev shells in general, even new to nixos and nix.

9

in your shell.nix, you can have something like this

mkShell {
  # ...
  nativeBuildInputs = [ pkg-config ];
  buildInputs = [ openssl ];
  LD_LIBRARY_PATH = lib.makeLibararyPath [ openssl ];
}

Thx, might you be able to help on why my rust analyzer keeps acting up over it not finding openssl?

11

did you run rust analyzer inside the dev shell?

12

How would I do that? I use vscodium

Wait, I might know how
