tethering does not work after updating from 4.6.0 to 4.6.1

[ms-photo]

Describe the bug

tethering has been working fine with my Nikon D850 and my Nikon D810 when using 4.6.0. After updating to 4.6.1 the tethering option does not show up, after switching the camera on.

all steps mentioned in the trouble-shooting guide have been executed successfully (see attached log):

• the camera is identified correctly
• gphoto2 is able to trigger the camera
• gphoto2 receives the image from the camera when using the trigger button of the camera

Steps to reproduce

1. start darktable
2. connect camera using usb cable
3. switch on camera

Expected behavior

darktable should offer to start tethering

in your description to reproduce an essential step is missing: connecting the cam for tethering in darktable: Are you sure you followed the description in https://docs.darktable.org/usermanual/4.6/en/tethering/overview/ (especially 3rd paragraph)?

Hello @MStraeten

yes, I did exactly that: the issue is: in the import section there is no button coming up when the camera is connected (and switched on). This was the case before I upgraded to 4.6.1

[TurboGit]

This is strange as nothing has changed in this area since 4.6.0. Are you sure 4.6.1 has been built with gphoto2 and so tethering mode enabled?

What is displayed for:

$ darktable --version

[ms-photo]

/Applications/darktable.app/Contents/MacOS % clear && ./darktable --version

this is darktable 4.6.1

This is strange as nothing has changed in this area since 4.6.0.

There are now two different builds?

[TurboGit]

I see, it is macOS... I have zero experience with this. I'll let macOS expert answer, sorry for the noise.

@ms-photo this is the homebrew based build of darktable. Can you please download and try the other arm64 package and report here.

We need to investigate if there is an issue with gphoto on homebrew based builds.

[MStraeten]

i tried it with my 4.6.1 build (the 12.5 arm64 build based on macports) and was able to connect my canon cam for tethering

[zisoft]

Ok thanks! So let's again dive into homebrew stuff...

[zisoft]

Strange, works for me too with my Canon, homebrew build.

I downloaded the x86_64 built and installed it (without homebrew) and it's working there. So the issue seems to be related to the homebrew built.

still not fixed

Given the comments that's not a dt issue but probably some library to connect to the camera missing. Anyway no need to keep this open.
