The commit

meson: use swiftc instead of swift for building	8d20b72653	Neko Asakura <[email protected]>	Dec 7, 2024 at 21:27

broke the building process under macOS 12.7.5 and swift 5.7.2.

After reverting the change of the commit 8d20b72 at the latest commit 83bb498 (use swift instead swiftc and use the correct compiler flags in osdep/mac/meson.build, the build is successful.

Expected Behavior

Successful build.

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of parameters, and conditions used in "Reproduction Steps".
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.

[Akemi]

can be reproduced on macOS 13 runner + xcode 14.2, see #15594 and https://github.com/mpv-player/mpv/actions/runs/12535858622/job/34958203214?pr=15594

@NekoAsakura any idea on this one?

@jdp1024 also on a side note, for future issues please post the whole build + configuration log and not just an excerpt of the error. it's important to have all informations we can get.

[Akemi]

the above error can be circumvented (temporarily) by setting -disable-bridging-pch to the swift flags. though it leads to another error.

seems like the temp path used for the generation of bridging PCH files is not writable/readable or something. path comes from getconf DARWIN_USER_TEMP_DIR.

new error might be related to

ld: warning: -undefined dynamic_lookup may not work with chained fixups

[Akemi]

i have a feeling we are hitting a linker bug here. especially when newer build tools don't exhibit this problem.

[NekoAsakura]

i have a feeling we are hitting a linker bug here.

I also think the issue might be related to linker:

1. The original build process did not use Xcode's linker.
2. Xcode 14.2 is the last version to support macOS 12.5+(https://xcodereleases.com/?q=14C18&scope=release), but Xcode 15 introduces a new linker designed to speed up static linking. (https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes#Linking)

I’ll need some time to figure out how to resolve this issue.

[jdp1024]

I tried -Dswift-flags="-save-temps" to keep the temp files, it did keep the files, but the pch file is not recognized.

@NekoAsakura i hoped that there might be some easy fix for this, flag or something (to the clang linker/compiler, llvm etc -Xcc, -Xclang-linker, -Xlinker, -Xllvm). if it is too much work it might not be worth it because see below. i already invested more than a day already.

this issue has pretty low priority and might not be fixed at all, because:

• we only support the latest 3 macOS versions (same as Apple and homebrew) for building (running i still macOS 10.15)
• there is no issue on macOS 13 with the latest build tools (xcode 15)
• we plan to add support for swift 6, drop swift 4 and older swift 5 versions, swift 5.8 might get mandatory and with that xcode 15 is also mandatory

[Akemi]

also might be interesting, though might be obvious (since it requests the classic/old linker). when adding -ld64 to our linker flags i can reproduce the same/similar error:

add_project_link_arguments(['-ld64'], language: ['c', 'objc'])

I was trying to trace which part is responsible for generating that .pch file but haven’t found any useful clues so far. I will keep an eye on it.

Anyway, happy new year :)

I know it's difficult to maintain for many OS versions, but there is something special about old Intel Macs: macOS 13/14/15 are all too heavy for them, some functions are limited, and the drivers are suboptimal. A working version of a daily-use tool like mpv means a lot.

Happy new year.
