            Bug ID: 486632
           Summary: Camera is never detected using bundled gphoto2
                    libraries
    Classification: Applications
           Product: digikam
           Version: 8.3.0
          Platform: macOS (DMG)
                OS: macOS
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Import-Gphoto2
          Assignee: digikam-bugs-null at kde.org
          Reporter: hh.abroad at gmail.com
  Target Milestone: ---

SUMMARY
The gphoto2 libraries packaged with the MacOS version of DIgiKam do not allow
the auto detection of my Canon EOS 7D camera.  When I install the gphoto2 and
libgphoto2 packages using brew, then create symlinks under the DigiKam
installation directory, I am then able to auto detect my camera correctly. 
I've had this problem for the last years and have only just found a solution.

STEPS TO REPRODUCE
1. Install DigiKam using the sources available in DMG format and setup
2. Connect the Canon EOS 7D camera using a USB cable
3. Go to the Cameras preference and click Auto-Detect

OBSERVED RESULT
An error message is displayed that no cameras can be detected

EXPECTED RESULT
A Canon EOS 7D should be detected connected to the USB port

SOFTWARE/OS VERSIONS
macOS: Ventura 13.6.6

ADDITIONAL INFORMATION
Installing the same versions of gphoto2 and libgphoto2 and then symlinking the
packaged directories and dylib files to the ones installed by brew allows the
camera to be detected correctly.

Below are the symlinks created under
/Applications/digiKam.org/digikam.app/Contents/lib:
libgphoto2 -> /usr/local/lib/libgphoto2
libgphoto2.6.dylib -> /usr/local/lib/libgphoto2.6.dylib
libgphoto2_port -> /usr/local/lib/libgphoto2_port
libgphoto2_port.12.dylib -> /usr/local/lib/libgphoto2_port.12.dylib
