Description Christophe Marin 2024-04-24 11:04:26 UTC 
The NVidia driver silently fails to build when using the mold linker:

Never heard about mold linker. Whatever. Unsupported.

Precisely. the nvidia driver package should only try to use what it supports.
Comment 4 Stefan Dirsch 2024-04-24 19:14:04 UTC 
You mean I should add a conflicts to mold package?
Comment 5 Christophe Marin 2024-04-25 07:55:26 UTC

The opposite, tell which linker to use.

If I take the nvidia package in X11:Drivers:Video:Redesign as model, adding `export LD=ld.bfd` in kmp-post.sh and kmp-trigger.sh would be sufficient.

Tested successfully locally.
Comment 7 Stefan Dirsch 2024-04-25 08:09:55 UTC 
Where is this LD env. variable documented?
Comment 8 Christophe Marin 2024-04-25 08:24:35 UTC 
/usr/src/kernel-modules/nvidia-550.76-default/Makefile contains: `LD ?= ld`
Comment 9 Stefan Dirsch 2024-04-29 01:28:45 UTC 
Ok. Understood.
Comment 10 Stefan Dirsch 2024-04-29 01:29:57 UTC 
Fixed. Will be available with package update for 550.78.
