KDE Neon: "sudo ninja -C build install" results in "FAILED: libfprint/FPrint-2.0.gir"

[github-klaus]

Using KDE Neon, following https://gist.github.com/leon-anavi/e19d77eafe1dc1800f170255b23a5839
However I use your code: git clone https://github.com/archeYR/libfprint-CS9711.git

Everything went fine until to the following command resulting in an error: sudo ninja -C build install
Could you help me, please, to resolve this error? FAILED: libfprint/FPrint-2.0.gir

Thank you very much!
Klaus

This looks like some distribution specific packaging/dependency problem (your g-ir-scanner appears to be broken), so there's not much I can do about this I am afraid.

As a workaround, you could try passing -Dintrospection=disabled for meson setup build.

[github-klaus]

Thank you so much for your instant reply!

With a small change to your suggestion everything works perfectly:

meson setup build -Dintrospection=false
ninja -C build
sudo ninja -C build install
sudo ldconfig
systemctl restart fprintd.service
fprintd-enroll
