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

Hi Feri,

My challenge is that I can't find how to build a 'development headers' version. I've tried this script<https://github.com/gonzalo/gphoto2-updater> and "Install libgphoto2 and gphoto2 from source on Raspberry Pi<https://hyfrmn.wordpress.com/2015/02/03/install-libgphoto2-and-gphoto2-from-source-on-raspberry-pi/>" to roll my own build, but those seem to leave me with a vanilla version, where I still need development headers for my downstream compatibility.



Is it something as silly as a switch I need to add to the 'make' step??

Are we talking cross purposes here? Are you talking about the OS while I'm talking about the app/package libgphoto-dev?



When bullseye becomes the latest stable release for the Pi, past performance suggests it will only have one build of libgphoto-dev for its entire lifespan as the stable release.



That's the problem I've hit with buster, and I expect will hit again in 12-18 months when new cameras have been added to the libgphoto project, but without any updated builds of libgphoto-dev (or I can figure out how to DIY) it will be trapped in February 2021 with the functionality from v2.5.27.

If the memory isn't too tight, it should be possible to rebuild natively.

Debian "unstable" get more or less regular uploads when new upstream versions are released.  These are migrated to "testing" a couple of days later (typically).  A new Debian release means that "testing" is renamed to "stable", so the version in the Debian stable release is frozen.

Bullseye is the current "stable", buster is "oldstable", stretch is "oldoldstable", and so on.  So yes, stable releases get outdated eventually.  See https://backports.debian.org/ for a possible solution.
