 Jake Hillion | hey all, I'm hoping this is the right place to ask about packaging problems with flakes. I'm trying to add a flake to a project that builds with meson (poor me) and having some trouble with run_command. The error I'm ending up with is:
meson.build:51:16: ERROR: Could not execute command `/build/source/meson-scripts/get_clang_ver /nix/store/hnfkms9dykvh61nwdqydzmbgzzr5lwy0-clang-wrapper-18.1.8/bin/clang'.
I did the usual things: replacing #!/bin/bash in the script with #!/usr/bin/env bash, running the script from my flake directory (./meson-scripts/get_clang_ver /nix/store/hnfkms9dykvh61nwdqydzmbgzzr5lwy0-clang-wrapper-18.1.8/bin/clang, works as intended), doing the same in nix develop -i which also works.
I ran nix build --keep-failed and got note: keeping build directory '/tmp/nix-build-scx.drv-4/build'. I cd'd to /tmp/nix-build-scx.drv-4/ (dropping the final /build, hoping that's where the script chroots) and ran ./build/source/meson-scripts/get_clang_ver /nix/store/hnfkms9dykvh61nwdqydzmbgzzr5lwy0-clang-wrapper-18.1.8/bin/clang in nix develop -i. Also worked. I'm a bit stumped how else to debug this, what else can I do when the problem isn't reproducible in an environment ignoring nix develop?

 Magnus | Is it impossible to write a flake to build a go project that has dependencies in private repos, or am I failing to find information on how to do it? | 13:12:42 |
 elikoga | You could pull the private repos in as a git Repo using ssh and a private key available to the user | 13:13:27 |
| Magnus | How? I'm failing to push any kind of git setup into the build environment of nix build .. | 13:17:01 |
| elikoga | This is a normal nix feature though someone should write that it does that in builtins.fetchGit | 13:17:12 |
| elikoga | I'm assuming the go repos are git repos? | 13:17:33 |
| elikoga | You can add them to the flake inputs too, and set isFlake =false
Or something like that | 13:18:01 |
| Magnus | I know builtins.fetchGet can do it, but go build isn't using it for obvious reasons. | 13:18:25 |
| Magnus | It sounds like you are proposing something very custom made, rather than using buildGoModule though, elikoga . | 13:19:24 |
| elikoga | Can you make go build fetch from local paths? | 13:19:27 |
| Magnus | You mean if I can go build in an interactive shell, yes. | 13:20:06 |
| Magnus | * You mean if I can go build in an interactive shell, yes I can. | 13:20:15 |
| elikoga | buildGoModule is very custom made though? | 13:20:33 |
| Magnus | If you by "custom made" mean, made for general consumption and therefore available in nixpkgs, yes then it's custom made. | 13:21:45 |
 flyx | In reply to @elikoga:matrix.org
Can you make go build fetch from local paths? you can have replace directives in your go.mod which can iirc point to local paths | 13:22:24 |
| elikoga | And then template the local Paths using the nix fetched git repos? | 13:23:11 |
| Magnus | flyx: ah, so then I'd have to rewrite go.mod on during the build? | 13:23:15 |
| Magnus | * flyx: ah, so then I'd have to modify go.mod on during the build? | 13:23:44 |
