 dacid44 | in general though, how would I do that for something that hasn't been packaged already? Do I have to fully package it myself, or is there a way to just plug in the name on crates.io and maybe a rust toolchain derivation or something and have it be built and installed as if by cargo install? | 17:04:42 |
 ghpzin | Packaging it yourself.

can help for simpler cases
But things like adding required native libraries or patching weird build.rs things would need manual fixes after. | 17:10:30 |
 Makuru | Figured it out! Needed to add llvmPackages.bintools. | 17:40:48 |

 n8henrie | Hi all -- relative novice, hoping someone can help me run a rust binary built outside of nix in a nixosTest (as part of a bisect to fix a problem upstream). I've been using runCommand to copy it into the test image with autoPatchelfHook providing the dependencies and dontStrip = true, but still getting symbol lookup error: /nix/store/...espanso/bin/espanso: undefined symbol: _ZN12wxWindowBase14RegisterHotKeyEiii at runtime (even though wxGTK32 is in the buildInputs).
Including all the buildInputs for an xorg-based linux system from https://github.com/espanso/espanso/blob/dev/nix/espanso.nix
Anyone know why copying a binary that runs fine outside nix into a NixOS VM would give me this wx-related missing symbol error when all the required libraries seem to be linked (at least I don't see anything obviously missing based on ldd)?
| 20:41:54 |
| ghpzin | Do you need to do something special during runtime to trigger it ? | 21:29:43 |
| n8henrie | To trigger the error? No, even a --version triggers it. | 21:37:40 |
| ghpzin | Can't reproduce, seems to work on both my machine and nixosTest.
Unless you use headless test for some reason. | 21:41:10 |
| n8henrie | No, not headless. You are building espanso from source on a non-nixos system with standard Rust tooling, copying the binary while patching with autoPatchelfHook, and then running it in nix, and it's working? | 21:42:48 |
| ghpzin | No, downloading .deb from releases page, doing all that and it runs.
Let me clean up things and push. | 21:52:28 |
| n8henrie | Oh interesting.
My ultimate goal is a git bisect on the source to fix an upstream bug that was introduced sometime in the last year and a half (ugh), so I'll need to be able to build from source, but that's a reasonable way to test. I'll give that a shot. | 21:54:02 |
| ghpzin | nix build github:ghpzin/nixpkgs/12e2905327c7efac6df82d587f0ef29f68a0cc43#nixosTests.espanso
xdg-open ./result/started.png

| ghpzin | nix build github:ghpzin/nixpkgs/12e2905327c7efac6df82d587f0ef29f68a0cc43#nixosTests.espanso

I do not think binary in their release .deb should be that different from build result from other distro. | 21:57:20 |
| ghpzin | Actually if binary built on other distro is the one with problems, maybe it is just a mismatch of wxGTK32 versions. | 22:09:52 |
| n8henrie | Hopefully not, I renovated the build system prior to the 2.3 release using a pretty standard ubuntu build process. Building now. | 22:10:00 |
| n8henrie | That could totally be it. | 22:10:12 |
| n8henrie | I bet you're right. Yup the deb version is working fine.
But now I'm not sure how to get a matching wxGTK32 version on Arch, but I can look into that.
It certainly would be much easier to just bisect by setting src = /path/to/espanso-src, but then cargoHash fails. I set it to look at Cargo.lock instead, but then there's a (or maybe more than one) git dependency that trips things up.
Are you aware of any way that I can override src in the package definition without the cargoHash stuff being wrong on every iteration of a bisect?
| 22:14:27 |
| n8henrie | Looks like wxgtk 3.2.8.1 on nix, 3.2.8.1-2 on arch. | 22:15:52 |
