Can't link libmpv (deb package) on Debian 11

[tsjnachos117]

Hello. Whenever I try to build an mpv package (which should include both the cplayer and libmpv), I get literally thousands of error messages, so many they don't fit in my terminal's 4,000 lines of scrollback. However, I noticed if I disable vulkan (-Dvulkan=disabled in mpv_options), the problems go away. I'll post the following (locally modified) files below: debian/rules, debian/config, mpv_options, and ffmpeg_options
modified_files.tar.gz

Here are some logs (meson-log.txt and build.ninja):
logs.tar.gz

PS: I think something similar happened when I reconfigured my scripts to use waf, but I don't remember for sure. I won't test right now, since it's past midnight and I'm tired, but maybe I'll do a test tomorrow.

Ok, waf has also failed:

Here is my ./mpv/build/config.log file:

I wonder: does waf have a log file I can upload?

Here are my modded files for using waf (debian/control and ffmpeg_options are the same, so I didn't include them):

@tsjnachos117 I also get glslang linking issues on Ubuntu 22.04 - my workaround is uninstalling glslang and compiling shaderc myself then building libplacebo+ffmpeg+mpv against that.

Do you have glslang-dev and related packages installed?
