#126 --capture-image won't keep picture on SD

[Luis Miguel]

I'm trying to get gphoto working and build a personal webgui for it.
Everything seems to work (detected camera, capture working, properties aquired...)
The only thing I'm not being able to do is to keep the photos on the camera SD.
I'm using the commands without any errors
gphoto2 --capture-image
gphoto2 --capture-image-and-download --filename=/store_00010001/DCIM/100D5000/DSC0001.JPG
gphoto2 --capture-image --keep

none of those work.

Any hint to get this working ?

Nikon DSC D5000 (PTP mode) usb:001,020
gphoto2 2.5.6
libgphoto2 2.5.7
libgphoto2_port 0.12.0

--set-config /main/settings/capturetarget=1 seems to fix it on terminal but not using webgui.
Always: Current: Internal RAM

should be a permissions issue, but no idea where.

[Marcus Meissner]

the capturetarget setting is saved in .gphoto/settings and should be stick

[Luis Miguel]

pretty sure the problem is in ~/Users/USERNAME/.gphoto/settings since the user is www-data. any way to point the settings to a folder with rw permissions ?

[Marcus Meissner]

you can copy a premade settings file to the ~wwwrun/.gphoto/settings home of wwwrun user ...

(just 1 line with:

ptp2=capturetarget=card

inside to switch to card capture)

You can set the HOME environment variable before calling libgphoto2 if you need another directory for $HOME/.gphoto/settings

[Luis Miguel]

Thank you for your message.
I have tried it and those where the steps made:

mkdir /var/www/.gphoto
nano /var/www./.gphoto/settings
ptp2=capturetarget=card
chmod -R 777 /var/www/.gphoto

but in the debug messages I still receiving:

So I know I have the settings file, the user www-data can read and write the file, but ghoto can't read the settings file.

Since I'm not a Linux Expert something should be wrong with my settings.

[Luis Miguel]

messing around with folders and permissions it's even worst:

that means the HOME environment variable is not set at all. if you set it in
your script,

export HOME=/var/www/

or similar before calling gphoto2

[Luis Miguel]

you were right.
This were the changes to python script

import os
os.environ['HOME']='/var/www'
