Failing to compile dav1d under Github CI and WSL Ubuntu 20.04 about ffmpeg-kit

[Fernthedev]

Everything seems to be in order, I'll be closing the issue now. Good day and hope this helps anyone else compiling on Ubuntu :)

This issue was fixed by installing meson using pip3 instead of apt. It seems that the Ubuntu packages use meson 0.53 while the latest is 0.58. Updating using pip3 fixed the issue, highly recommend to add to the common troubleshooting wiki :)

I'll keep this open just so it can be noticed, feel free to close after.

Thanks, added an entry about this case in Troubleshooting.

Just wanted to mention that I was seeing this same issue with v0.53. This post was super helpful in getting passed the initial issue I found. However, I tried building this with meson v0.55.3, and it was not picking up the built-in options from the cross file:

[built-in options]
default_library = 'static'
prefix = '${LIB_INSTALL_PREFIX}'

The resulting meson-private/dav1d.pc file had a default prefix (i.e. /usr/local)
Also, the library was built shared instead of static.

After upgrading meson to v0.58.1, this issue went away. My guess is that this cross file is using a feature that was introduced at some point between v0.55.3 and v0.58.1. Unfortunately, I'm not familiar enough with meson to know what this might be.
