synaTudor failes to compile on Fedora 39

[aboutdavid]

I'm not really good at bug reporting, sorry. I've managed to get meson build and ninja to work, but installing it seems to fail.

ninja: build stopped: subcommand failed.

I couldn't find a packaged version of fprint-tod that would work so I took it from packages.ubuntu.com and compiled it successfully. Should I get another version, or should I try something else?

[Popax21]

It seems like the libfprint-tod version you got is rather old and misses some stuff the tod module depends on. I would recommend trying to just install it from source instead of using the Ubuntu package (I can link the upstream repo later if you have issues locating it).

[aboutdavid]

Ah sorry. I don't deal with building things often lol. Is this the upstream repo? https://gitlab.freedesktop.org/3v1n0/libfprint/-/tree/tod

[aboutdavid]

Okay thank you. I also face one last issue. I installed fprintd to get the fprintd-enroll command, but it keeps saying nodevicesfound. Both services that are supposed to be running are running without failure it seems, however.

Setting SELinux to permissive does not work (even after starting both processes once more)

[Popax21]

You'll need to link fprintd against libfprint-tod, not just install it from the package manager.

[aboutdavid]

Sorry, how would linking it work? I'm unsure. I tried looking, but I can't seem to find a way.

[Popax21]

Assuming you have built and installed libfprint-tod from source, you would have to do the same thing for fprintd.
