Description Than Ngo 2023-08-11 18:16:50 UTC 
chromium failed with Relink `/lib64/liblpcnetfreedv.so.0.5' with `/lib64/libm.so.6' for IFUNC symbol `sincos'



Reproducible: Always

Steps to Reproduce:
1. build chromium in rawhide

Actual Results:  
chromium failed with Relink `/lib64/liblpcnetfreedv.so.0.5' with `/lib64/libm.so.6' for IFUNC symbol `sincos'

Build log: https://kojipkgs.fedoraproject.org//work/tasks/7934/104677934/build.log


Expected Results:  
it should build without any probkem
Comment 1 Richard Shaw 2023-08-11 22:22:25 UTC 
I guess first I'd like to understand why chromium is using this package as a dependency. As the name implies, it's a fork of LPCNet specifically for use with FreeDV.

chromium has Build Require on ffmpeg which has dependency on codec2 that has direct BR on lpcnetfreedv.
Comment 3 Richard Shaw 2023-08-13 21:52:04 UTC 
Ok, I'm still confused. If I look at the f39 builds I did codec2 seems to have the correct soname dependency on lpcnetfreedv...

The error message is correct.

The object is underlinked. It uses math library functions without linking with -lm.
Comment 5 Richard Shaw 2023-08-14 11:35:35 UTC 
Ahh... That makes more sense, but I found the chromium output "relink" confusing. Fix coming.
Comment 6 Richard Shaw 2023-08-14 13:51:41 UTC 
Rebuilds are complete for Rawhide and branched f39.
Comment 7 Fedora Release Engineering 2023-08-16 08:14:17 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
