@XAVeRY Same issue. Tried many older versions of meson unsuccessfully. I would appreciate some actual help instead of "don't use it". This is the only option for these sensor models. Left a comment to the dev, maybe the syntax error will be fixed. Can you suggest a workaround?
@kekekekw libfprint's meson.build is borked with newer meson versions, so even if you had managed to get any further with this, you would've gotten this error :
libfprint/meson.build:162:3: ERROR:
Trying to compare values of different types (NotFoundDependency, list) using !=.
This was deprecated and undefined behavior previously and is as of 0.60.0 a hard error.
Maybe it's for the best, though. Development of this plugin has been halted by the author and there's a report of the driver not working at all past kernel 5.4. I wouldn't be getting my hopes up.
Perhaps it's best to just let this package (and all the packages related to it) simply die off.
Been trying to build this for hours, now I've just about given up at this point... help if possible. I do have meson 0.51 installed, but it doesn't work for whatever reason. (https://pastebin.com/EFaejMS7)
@xavery can you please tell us how to build fprintd-vfs_proprietary? I've been to the git link but failed to understand anything :(.
OK. it got them installed. Thx, Xavery!
@xavery: I did makepkg -f in the source directory of the package and I have also now all dependencies, but at the end I get this symbol link error. I would delete the file, but i can't find it:
"ln: die symbolische Verknüpfung './vfs_proprietary' konnte nicht angelegt werden: Die Datei existiert bereits ==> FEHLER: Ein Fehler geschah in prepare(). Breche ab..."
@mx333 : Your source directory has the files which were patched by the previous unsuccessful run of makepkg. You need to restart the process from scratch by running makepkg -C.
Please familiarise yourself with https://wiki.archlinux.org/index.php/Makepkg before asking further questions.
@xavery: I installed all dependencies but get still the error:

And I do not understand the questions "Assume -R"? What is the answer for that? "y" ?

@43615 XAVeRy's comment is pretty on point though. I can try rewriting this package's meson.build for newer meson versions, however the point still stands that this package has not been functional on recent kernels (that is, it doesn't work at all). I'll look into updating the build file, though as has been said, I'm not too hopeful on this package working.
