 emily | I just mean that "just make the existing expressions build on Darwin" may be comparably trivial | 17:41:28 |
| emily | the things that need doing are mostly not hard, just… nobody with the time to do them :) | 17:41:52 |

I saw the PR for OpenJDK source build for Darwin a few days ago, but couldn't find it 1/2 hour ago. I recall reading there were provenance issues with Xcode. Ah yep I remember that PR | 17:51:36 |
| Infinidoge 🏳️⚧️ | The problem being that compiling it requires Xcode, which is non-viable for Nix | 17:51:50 |
 msgilligan | I found this issue: https://github.com/NixOS/nixpkgs/issues/313213 | 17:51:50 |
| msgilligan | (I remember doing a GUIX build with Xcode once, but that wasn't part of GUIX itself) | 17:52:47 |
| msgilligan | Why is Xcode non-viable? | 17:53:52 |
| msgilligan | (I realize it's both binary and non-free, but just curious exactly how non-viable is defined in this context) | 17:54:23 |
| Infinidoge 🏳️⚧️ | Pretty sure it would directly violate Xcode's license | 17:56:30 |

| Infinidoge 🏳️⚧️ | Not to mention needing Darling or a VM to even run it on Linux, making cross-compiling impossible | 17:58:10 |
| Infinidoge 🏳️⚧️ | Or at least extremely impractical | 17:59:46 |
| Infinidoge 🏳️⚧️ | https://docs.godotengine.org/en/2.1/development/compiling/cross-compiling_for_ios_on_linux.html | 17:59:48 |
| Infinidoge 🏳️⚧️ | Godot's page about it makes it seem... extremely not fun | 17:59:57 |
| Infinidoge 🏳️⚧️ | Not the worst, but not fun | 18:00:08 |
| emily | uhh, why does Xcode even come into this | 18:00:09 |
| Infinidoge 🏳️⚧️ | From what I remember of the PR, compiling the JDK properly for Darwin required Xcode | 18:00:29 |
| emily | we have a full native LLVM toolchain and macOS SDK in Nixpkgs | 18:00:33 |
| Infinidoge 🏳️⚧️ | Cool that works then | 18:00:44 |
| emily | you only need Xcode itself in rare cases like the metal command-line tool or ibtool | 18:00:45 |
| emily | it's not inconceivable that the WebKit build in OpenJFX wants metal or something but I'd be extremely surprised for OpenJDK | 18:01:05 |
| emily | ok, this is before the 24.11 SDK rework also | 18:01:40 |
| emily | so everything was very different/harder then | 18:02:04 |
| emily | I truly think it's probably as easy as turning off GTK/JavaFX, maybe turning off the X11 dependencies, maybe adjusting some of the prefixed tool stuff, and firing off a build | 18:03:37 |
| emily | I could give pointers for any particular errors that come up but I don't expect any "fundamental" obstacle | 18:04:02 |
| msgilligan | I'm tempted to dive into this right now, but I really have too much I'm already committed to on my plate. And it is a task that is currently above my skill level, so I don't think it would be easy for me. I wish I had more time. | 18:12:28 |
| msgilligan | I'd like to make sure two things from this conversation are captured in GitHub Issues:
- The idea of using
jlink to add OpenJFX to Temurin. Which should allow Darwin to use Temurin rather than Zulu.
- Whatever technical details emily is explaining above that are not already covered by existing issues.
| 18:15:15 |
| emily | FWIW I haven't actually tried the jlink thing so I could be wrong about how it works :) | 18:18:30 |
| emily | feel free to open issues though | 18:18:41 |
| emily | I think in any case that it's likely not too hard to get OpenJFX building from source on Darwin even if jlink doesn't work. but I would really rather avoid building two JDKs in general | 18:18:57 |
