build: provide a seperate python3-dlib dependency package on debian

[eatyourbaby]

Since PEP 668, system-wide Python packages are exclusively managed by package managers, which breaks dlib install on Debian-based OS (#774,#807). Although it's possible to override this behaviour, it can potentially break system packages. Therefore, this PR changes Debian control files to install a separate python3-dlib dependency package.

Unfortunately, python3-dlib doesn't exist as an official Debian package. However, since the deb file is provided via Ubuntu PPA, it is easy to provide python3-dlib package in the same repo with stdeb.

pypi-download dlib
py2dsc dlib-[version].tar.gz

This will automatically build a Debian source package that can be directly uploaded to Launchpad for building.

I have successfully built the packages with the latest beta. You can find the binary packages here.

You mean that gdebi the two packages in your release will fix the issue, right?

[Winson-Huang]

I tried this way, but the python3-lib package's dependency libstdc++6(>13.1) is not satisfied in Debian 12

[eatyourbaby]

@Winson-Huang I use Debian trixie, which uses GCC 13. I rebuilt the packages on bookworm and they should work for you. They're the deb12 variant on the same release page.

Nice! I downloaded the deb12 variant, and it works on Ubuntu 23.10, just needs some extra stuff. I had to install libinih-dev, it ended with an error, but sudo apt --fix-broken install fixed it. When I tried to add a face using sudo howdy add, it dropped an error, and requested that I run sudo howdy config and change the device_path value, so I did. I ls'd /dev/v4l/by-path/, and have seen the camera devices, selected the one that end with index0, and so changed the value to /dev/v4l/by-path/pci-0000:00:1a.7-usb-0:2:1.0-video-index0. Now I could add a face without problems, and the authentication works!

The debian12 python3-dlib package is working with his howdy_3.0.0 package for me, but its not really stressing dlib much.

I am experiencing the same issue (cc https://github.com/boltgolt/howdy/issues/774#issuecomment-2232828419 ). However, the binaries provided in the description of this PR don't work for me.

Installation fails on python3-dlib (and I have a version of libjpeg-turbo installed)

I was installing on Mint DE 6 (Debian 12 based) . I had python3-full installed. libjpeg62-turbo is available and should have installed. On Wednesday, July 17, 2024 at 04:20:37 AM CDT, Pierre Fenoll @.***> wrote:

I'm getting the same on Ubuntu 24.04. Do we need a new build? The ones available are a year old.
