make.log

strange error appeared after arch linux update to 4.19.11-arch1-1-ARCH kernel, see make.log attached (in russian)
error translates to

objdump: /var/lib/dkms/rtl8723bu/4.3.6.11_12942.20141204_BTCOEX20140507-4E40/build/core/.tmp_rtw_security.o: unable to initialize decompress status for section .debug_info

installed elfutils but th error persists

I encountered the same issue when upgrading to 4.19.11-arch1-1-ARCH. Downgrading both elfutils and libelf to 0.174-1 (+ adding them to IgnorePkg) and then upgrading linux, linux-headers, etc. worked for me. After rebooting, the driver compiled just fine.

[cypa]

yes, that works, but what should we do next?

[lwfinger]

Complain to ARCH. They are the ones that screwed something up.

So, I had a similar issue trying to install this drive in KaOS:
Install script
But I'm not sure how it would be an elfutils issue, since the driver installed fine on Ubuntu Disco Dingo, and it seems they both have elfutils version 176-1.

[lwfinger]

This is more likely to be a compiler problem. Do they have the same version of gcc?

[pseudotheist]

So far as I can tell, they seem to be the same version:
Ubuntu: "Version: 4:8.3.0-1ubuntu3"
KaOS: 8.3.0-1
