@dbermond Thank you very much. At now, the issue is fixed, and the build process is successfully finished.

@Anquihald This is an upstream issue. I have opened an issue upstream and you can track it there.

Hello2All!

I need libhwy for my custom mpv build, but build fails with link error. Any fix?

@sohex It compiles fine for me for the stock x86_64 (x86-64-v1) instruction set, which is the default for Arch Linux. It also compiles fine for me when using '-march=alderlake'. You can try to build the package in a clean chroot, to isolate the build from your environment. This is how the packages in the official repositories are built.

sohex commented on 2024-04-08 20:07 (UTC)

@dbermond Interesting, which instruction sets is it building for on your system? I see the test failures on AVX2 and SSE4 tests specifically. I just tried dropping in the default makepkg.conf on my system, but with that the build fails completely, so entirely possible it's something with my environment. I also realize now that I completely misread that line from the readme as "should be compiled with optimizations enabled - without inlining" instead of "should be compiled with optimizations enabled" & "without inlining SIMD code may slow down...".

dbermond commented on 2024-04-07 11:26 (UTC)

@cfutro I have just checked, and the package is building fine with the default Arch Linux compiler flags, which already have '-O2'. All tests are passing. Check your compiler flags in use.

cfutro commented on 2024-04-07 10:24 (UTC)

I'm not able to build this package without setting -fno-inline, without it two tests fail. Looking at the readme on the github page it seems like that might be preferable to add in general anyway:

Applications should be compiled with optimizations enabled - without inlining, SIMD code may slow down by factors of 10 to 100. For clang and GCC, -O2 is generally sufficient.

@jholmer This is an upstream issue that is now fixed in latest git master.

There are many failures occurring in the tests phase with "undefined reference to hwy::ThreadPool::WorkersReadyBarrier()". A workaround could be to disable building the tests with -DHWY_ENABLE_TESTS:BOOL='OFF'.

@Fifis This was an upstream issue and is now fixed by them.
