[Pkg-phototools-devel] Upgrading ligbphoto2-dev on a Pi??

[Greig Sheridan]

Hi,


I'm the author of an open-source timelapse camera controller<https://github.com/greiginsydney/Intervalometerator/blob/master/docs/upgrade.md> app that uses python-gphoto2 to talk to DSLR cameras over USB. The hardware platform is the Raspberry Pi.

Python-gphoto2 relies upon the 'development headers' build of ligbphoto2, and I've been historically installing that on the Pi with "apt-get install libgphoto2-dev".

This is currently built on v2.5.22 which was released in January 2019, and my app is now falling behind in support for cameras released since then as a result.

My attempts to update this have failed, so I was wondering if there's a means by which someone can petition for an updated version - or perhaps it already exists and I'm just not finding it?

I've struggled to find a documented process to create my own 'development headers' build by hand. I was able to locate Debian's "Package: libgphoto2-dev (2.5.27-1)<https://packages.debian.org/bullseye/libdevel/libgphoto2-dev>" but my attempts to install it failed when I hit a brick wall getting the dependency for libc6 to install:

The following packages have unmet dependencies:
libc6 : Depends: libgcc-s1 but it is not installable
         Depends: libcrypt1 but it is not installable
         Recommends: libnss-nis but it is not installable
         Recommends: libnss-nisplus but it is not installable
E: Unable to correct problems, you have held broken packages.


Is "libgphoto2-dev" being actively updated or is it stalled/abandoned? Should the latter be the case, I'd greatly appreciate any links or pointers to how I might be able 'roll my own' installation.


Thanks.
