.capture errors out (canon 40d)

[ciapecki]

here is the output of running example.rb is it something that can be fixed?

is it possible to have a live view with your wrapper (same as gtkam has while clicking on Capture Image... from the left pane)

thanks, chris

do you have gphoto2 command line tool installed? can you run "gphoto2 --capture-image" or "gphoto2 --capture-image-and-download" or "gphoto2 --capture-preview"?

Is your focus mode set to manual or auto?

[ciapecki]

all these commands work fine from command line: chris@chris-ub:~$ gphoto2 --capture-image-and-download New file is in location /capt0000.jpg on the camera

chris@chris-ub:~$ gphoto2 --capture-preview Saving file as preview.jpg

and the pictures can be found on disk.

ruby example.rb returns though: example.rb:20:in `capture': LibGPhoto2 function returned: Unspecified error (GPhoto2::Exception) from example.rb:20

I also get the same exception with Canon 450D. I am able to capture without an issue using the ffi-gphoto2 gem too.
