 emily | does it only support ELF even on Darwin? | 20:14:45 |
| emily | looking at the code… does this program actually work on Darwin? | 20:15:34 |
| emily | it seems to make a fair few assumptions about the system being ELF-y | 20:15:40 |
| Randy Eckenrode | Yes. There’s an open issue for Mach-O support, but it’s old.

 JoelMcCracken | I heard something about nixpkgs dropping x86_64-darwin support, is that discussion happpening anywhere easy to find?
| 20:16:14 |
| emily | it has paths like /usr/lib and /etc/ld.so.conf hardcoded though | 20:16:33 |
| emily | it's in the 25.11 release notes, https://github.com/NixOS/nixpkgs/pull/415566 | 20:16:47 |
| emily | I was meaning to post it on Discourse too though, I should do that | 20:16:56 |
| Randy Eckenrode | Note that that wouldn’t happen until 26.11. The announcement about dropping support in DetNix is unrelated to our schedule. | 20:17:49 |
| Randy Eckenrode | Does the latter even exist on NixOS? | 20:18:34 |
| emily | I think no, but I guess it can not-exist gracefully | 20:18:54 |
| emily | I'm just surprised if this program runs on macOS at all | 20:18:59 |

This is the test result, making the above change to use the pkgsCross (but not pkgsStatic!) coreutils.

| dbaynard | Thanks for your help. I should have been more explicit that this is working, reasonably, for me (I haven't used all the functionality but I have found it useful as a tool that works on macos that can analyze ELFs). I'll ask in the cross compile channel, when I return to this. | 23:50:07 |
| emily | no worries :) | 23:50:38 |
| emily | I agree with Randy Eckenrode about the best way to test it | 23:50:44 |
| emily | pull in clang-unwrapped on all platforms and make a couple basic .sos with --target= | 23:51:16 |
| emily | no need for pkgsCross | 23:51:25 |

| emily | will try to take a look at this tomorrow | 00:39:43 |
| Randy Eckenrode | There were some build changes, but I rolled most of it into the 14.0 PR. | 00:40:19 |
| emily | did you see https://github.com/NixOS/nixpkgs/pull/453094 and https://github.com/NixOS/nixpkgs/pull/453106 btw? | 00:40:26 |
