error when building

[ghost]

I'm sure I've missed something, but I wonder if you could help me to figure this out.

Using Debian 11 64-bit.

I've installed all the libraries and dev packages.

This is the output I get

This is caused by API changes in libavfi... I made it compile (though not sure if all changes are correct). Looks like imlib2 is not interested in using the new loader... Any more steps required other than copying the shared library?

Edit: My issue was feh not knowing about avif... It has to be started with FEH_SKIP_MAGIC=1. Still fails to load the image, but I will try to find some time to fix this.
