I was able to install it from source cloning the repo and running the meson commands although I had to install dlib and the other package system-wide since howdy runs as sudo, previously I only had them installed as user. (They're still building right now but it looks like it should work since I previously did the same thing only for user-wide)

[Abdul-Kaium5]

it was auto solved idk anything !

Had the same error on Arch (EndeavourOS) using howdy-beta-git from AUR and no idea how to fix it. Could anyone explain what that cpython build error message "lto1: fatal error: bytecode stream in file ‘dlib_build/libdlib.a’ generated with LTO version 12.0 instead of the expected 13.0 compilation terminated." actually means? Is this an Arch (AUR) issue with the PKGBUILD? What needs to be changed there?

[Reginald-Gillespie]

@nursoda I did finally get it working on my system. To why it won't install, there are a few issues, the first is that python-dlib does not install from AUR (which is an issue on their end), which is a dependency of howdy. Installing with pip works just fine, but arch wants the aur version since the aur version is listed as a dependency of howdy.

You can create a dummy PKGBUILD file that claims to provide python-dlib after installing pip to get around this (in theory, there's probably a bunch of bad side effects to doing this), but I found it doesn't actually recognize my face when doing so (not sure why, it just doesn't work).

But I did get it working, file permissions you might have to look into to make sure it's secure, but you can just clone the repo, follow the install instructions, you'll then need to install dlib with pip, theres another face recognition dependency as well, then iirc one more command for installing the face recognition models, but iirc everything tells you exactly what commands need to be run / what libraries need to be installed, then you need to find where the pam_howdy.so file to use in the pam files. For me it was in /usr/local/lib/security/pam_howdy.so, if you can't find it try sudo find / -name "pam_howdy.so". Once you have that, you should be able to follow the arch wiki about howdy, using that file instead of pam.py.

For file permissions, you can probably just follow most of what the PKGBUILD file for howdy does. Personally I just didn't touch anything since my pam file was already in lib security, although it might be leftover files from all the testing I did that still work because howdy is now on the path.

Also see this comment and the following ones (i.e. those above): https://aur.archlinux.org/packages/python-dlib#comment-956388

Apparently pacman now makes option link time optimization (LTO) enabled by default.

And you might be able to fix it by uncommenting the ##options=(!lto) in file PKGBUILD.

[Reginald-Gillespie]

Good find - I don't want to test it in case I break my current install (although I probably will at some point for the sake of being able to update howdy with pacman), but yes the error mentioned there, "generated with LTO version 12.0 instead of the expected 13.0", is the same one preventing me from installing dlib from pacman iirc so most likely that would resolve the issue.
