 vcunat | There's an interesting question of how to deal with .meta.platforms and propagation from dependencies. I guess the topic belongs to stdenv?

 hexa | firefox on release-23.05 crashes due to the way how libstdc++ gets linked into firefox and I'm completely out of my depth | 13:02:04 |
| hexa | https://github.com/NixOS/nixpkgs/issues/269571#issuecomment-1825621198 | 13:02:05 |
| hexa | only affects 23.05, both 23.11 and unstable seem fine | 13:02:52 |

 trofi | If firefox is linked by clang I wonder if cc-wrapper was supplying only libstdc++.a library in it's library search paths. Something like https://github.com/NixOS/nixpkgs/commit/2946b819c209f4a1a9e87a725fc9e5ed2452c178 might nave been a fix. You should be able to add needed library search path with explicit -L to firefox. | 14:16:01 |
| nbp | This sounds like it is build using clang, to make use of LTO:
https://github.com/NixOS/nixpkgs/blob/8f1180704ac35baded1a74164365ac7cdfba6f38/pkgs/applications/networking/browsers/firefox/common.nix#L171-L174 | 14:21:33 |
| trofi | Yeah, clang++ uses static libstdc++ in nixos-23.05 branch:
$ nix develop -f. firefox-unwrapped
$ dev>printf "#include <iostream>\nint main() { std::cout << 'x'; }" | clang++ -x c++ - -o a -Wl,-t |& fgrep stdc |& head -n3
/nix/store/jma71mvzwdrcm6qc5izvskvzfsii5mk7-gcc-11.3.0/lib64/gcc/x86_64-unknown-linux-gnu/11.3.0/../../../../lib64/libstdc++.a(globals_io.o)
/nix/store/jma71mvzwdrcm6qc5izvskvzfsii5mk7-gcc-11.3.0/lib64/gcc/x86_64-unknown-linux-gnu/11.3.0/../../../../lib64/libstdc++.a(ios_init.o)
/nix/store/jma71mvzwdrcm6qc5izvskvzfsii5mk7-gcc-11.3.0/lib64/gcc/x86_64-unknown-linux-gnu/11.3.0/../../../../lib64/libstdc++.a(eh_personality.o)
| 14:24:44 |
| trofi | staging-next for comparison uses shared one:
$ nix develop -f. firefox-unwrapped
$ dev>printf "#include <iostream>\nint main() { std::cout << 'x'; }" | clang++ -x c++ - -o a -Wl,-t |& fgrep stdc |& head -n3

| nbp | Would cherry-picking the change fix the issue? | 14:26:38 |
| nbp | Or should we look at something specific for Firefox? | 14:26:52 |
| nbp | * Or should we should look at something specific for Firefox? | 14:26:59 |
| trofi | I think cherry-pick will be a world rebuild. I would suggest exploring local to firefox fix like adding an equivalent of NIX_LDFLAGS = "-L${stdenv.cc.cc.lib}/lib" under stdenv.isGNU. | 14:28:41 |
| nbp | hexa: Does that sounds good? ^ | 14:29:43 |
| hexa | sure, we can try that | 14:31:58 |
| hexa | thanks trofi! | 14:32:36 |
