Gphoto snap cannot detect any cameras

eberkund · March 22, 2019, 6:30am

I am having trouble getting my gphoto snap to detect any cameras. It looks like inside the snapd environment it is unable to fully load all of the required dynamic libs.

Here is the snapcraft.yaml

name: gphoto2
version: latest
version-script: |
  gphoto2 --version | head -n 1 | sed 's|gphoto2 ||'
summary: The gphoto2 command-line tool for accessing and controlling digital cameras. 
description: |
  gPhoto2 is a free, redistributable, ready to use set of digital camera
  software applications for Unix-like systems, written by a whole team of
  dedicated volunteers around the world. It supports more than 2500 cameras

  gPhoto2 runs on a large range of UNIX-like operating system, including Linux,
  FreeBSD, NetBSD, MacOS X, etc. gPhoto is provided by major Linux 
  distributions like Debian GNU/Linux, Ubuntu, Gentoo, Fedora, openSUSE,
  Mandriva, etc.

  libgphoto2 is freely available and distributed under the terms of the GNU 
  LGPL.; the other gphoto programs are freely available and distributed under
  the terms of the GNU GPL.

  Newer libgphoto2 versions also support Media Transfer Protocol (MTP) based 
  media players since their communications protocol is based on the Picture 
  Transfer Protocol (PTP).

Have you connected the snap to the raw-usb interface?

Anyway the driver loading problem might be solved with the layouts feature, or by hardcoding the LIBDIR during build configuration phase.

eberkund · March 22, 2019, 3:15pm

Yep, doesn’t make any difference.

Yeah I was trying to do that by modifying the LD_LIBRARY_PATH variable however I am not sure which variables gphoto is using and haven’t been successful so far.

Pretty sure this is the relevant info:

0.002348 gp_port_info_list_load [gphoto2-port-info-list.c:288](0): No iolibs found in '/usr/lib/arm-linux-gnueabihf/libgphoto2_port/0.12.0'

lucyllewy · March 22, 2019, 3:31pm

add base: core18 to your yaml. This will light-up new functionality such as layout support. Then you can add this layout to your yaml which will make the library files appear where gphoto is searching for them:

layout:
  /usr/lib/$SNAPCRAFT_ARCH_TRIPLET/libgphoto2:
    bind: $SNAP/usr/lib/$SNAPCRAFT_ARCH_TRIPLET/libgphoto2
  /usr/lib/$SNAPCRAFT_ARCH_TRIPLET/libgphoto2_port:
    bind: $SNAP/usr/lib/$SNAPCRAFT_ARCH_TRIPLET/libgphoto2_port

@lucyllewy Thanks for the tip, that fixes the issue with not loading the camera drivers however it still doesn’t detect any cameras.
