error: linking with `cc` failed: exit status: 1
(...)

| 13:25:32 |
| Leonardo Santiago | I didn't remove nor add any new things, just nix flake update nix && nix build | 13:26:20 |
| Leonardo Santiago | Robert Hensing (roberth): did anything change in the libs side? I tried looking this error up and all I could find was a gcc version mismatch on different libraries, not sure that's the case here | 13:27:17 |
| Leonardo Santiago | * I didn't remove nor add any new packages, just nix flake update nix && nix build | 13:28:34 |
| Leonardo Santiago | is this a problem with libstd++? maybe a version mismatch? | 13:36:39 |
| Leonardo Santiago | nix/2.28.0 seems to be fine, nix/2.29.0 does reproduce the issue | 13:42:58 |
| Leonardo Santiago | sadly I'm looking for libflake-c upgrades, 2.28.0 doesn't seem to contain, time to do some git bisect | 13:44:31 |

 Robert Hensing (roberth) | Hmm yeah. Was going to say no major changes on our side | 14:14:43 |
| Leonardo Santiago | it seems that it might be related to the nixpkgs upgrade in nix | 14:15:12 |
| Leonardo Santiago | though I'm not sure how, maybe it changed the major version of cc (is it using clang?) and the one I'm using is incompatible with it? | 14:15:44 |
| Leonardo Santiago | I looked up your nixops4 setup and it seemed pretty similar (almost exactly the same) as mine so I don't know what I'm doing wrongly | 14:16:13 |
| Robert Hensing (roberth) |
clang?
Not on linux
| 14:16:18 |
| Leonardo Santiago | oh, so it's on gcc? that may be it, you have some gcc measures that I'm not using | 14:16:45 |
| Robert Hensing (roberth) | I do use clang on linux in my dev shell when hacking on the thing | 14:17:38 |
| Leonardo Santiago | I'm not a super c++ guy but the only instance I found someone commenting this was because of a gcc13 -> 14 version mismatch and so I think that'd be the issue here too | 14:18:03 |
| Robert Hensing (roberth) | May be possible to build it that way with pkgsLLVM | 14:18:07 |
| Leonardo Santiago | especially given that it is a nixpkgs upgrade | 14:18:08 |
| Leonardo Santiago | wdym? | 14:18:20 |
| Robert Hensing (roberth) | Something like nix build nixpkgs#pkgsLLVM.nixVersions.git | 14:19:03 |
| Robert Hensing (roberth) | It's not the most reliably buildable package set, but if it works... | 14:19:30 |
| Leonardo Santiago | oh, it was building fine with gcc before, I'll try to add your gcc countermeasures and see if that fixes it | 14:19:45 |
