 emily | only infelicity is that if they ever do actual versions the ordering will be weird | 17:52:58 |
| emily | but I doubt anything actually cares about the value | 17:53:09 |
| emily | that will start failing when they go over 65536 commits too fwiw | 17:53:49 |
| emily | or well, start truncating | 17:53:54 |
| emily | I'm not convinced anything actually cares about the "current version" field of a library though | 17:54:29 |
 Randy Eckenrode | Many times projects just set junk versions. The versions for llbuild’s framework are 1 and 1. | 17:54:31 |
| emily | yeah | 17:54:48 |
| emily | so just dropping VERSION … would be another option | 17:54:54 |
| emily | but it'll change the filenames used on Linux | 17:54:58 |
| emily | well, and on macOS too | 17:55:05 |
| emily | -rwxr-xr-x@ 1 emily staff 608K 8 Dec 16:09 libmtmd.0.0.7325.dylib*
lrwxr-xr-x@ 1 emily staff 22B 8 Dec 16:09 libmtmd.0.dylib@ -> libmtmd.0.0.7325.dylib
| 17:55:11 |
| emily | aha | 17:55:20 |
| emily |
For shared libraries, the MACHO_COMPATIBILITY_VERSION and MACHO_CURRENT_VERSION properties can be used to override the compatibility version and current version respectively.
| 17:55:22 |
| emily | so another option is to simply add MACHO_CURRENT_VERSION 0 to both of these | 17:55:40 |
| emily | that will maintain the same filenames on both platforms but remove the field in the dylib that is already getting truncated and that probably nobody cares about | 17:55:59 |
| emily | that is probably what I would upstream as the minimal change | 17:56:08 |
| emily | if they start doing actual releases with normal numbers they could then start putting that information back in without messing up ordering | 17:56:25 |

| Randy Eckenrode | Swift 6.2.2 is out. I should see how badly everything breaks …. | 02:19:35 |
| Randy Eckenrode | … why does Mesa depend on Swift? | 02:25:17 |
| Randy Eckenrode | I updated my KosmicKrisp branch. It’s getting closer to MoltenVK in terms of coverage. | 02:35:52 |
| Randy Eckenrode | My status for tonight is I got swift-llbuild and swift-tools-support-core building dylibs — somewhat similar to how Darwin toolchains do it. | 02:50:37 |
| Randy Eckenrode | Up next is Swift Compiler Driver once I finish rebuilding back up to having a bootstrap compiler. | 02:50:55 |
| Randy Eckenrode | My goal is to have these packages building using CMake exclusively. I liked the idea of using SwiftPM once it could be built, but it makes the bootstrap path more complicated. | 03:04:59 |
| Randy Eckenrode | Hmm. The LLVM for for Swift 6.3 is LLVM 21.1.6. | 03:05:45 |
| Randy Eckenrode | https://github.com/swiftlang/swift/blob/8bf0adb5b25fe23f20130c0a2635b7319517dba0/utils/build_swift/build_swift/defaults.py#L51 | 03:06:44 |
| Randy Eckenrode | Interesting. Apple’s fork is realigning its versioning strategy to more closely follow LLVM? | 03:07:36 |
| Randy Eckenrode | I wonder if they have a problem with people being confused about what version they’re shipping. | 03:07:49 |
