Hi I tried to install libgphoto2 from github without success. I followed what is described here .

it generated this: /usr/local/bin$ ls

gphoto2-config gphoto2-port-config (shouldn't I have gphoto2 as well ?)

and :/usr/local/lib$ ls *gphoto*

libgphoto2.la libgphoto2_port.so libgphoto2_port.so.12.0.0 libgphoto2.so.6 libgphoto2_port.la libgphoto2_port.so.12 libgphoto2.so libgphoto2.so.6.1.0

libgphoto2: 2.5.22.1 print-camera-list

libgphoto2_port: 0.12.0

at the end I get errors ./sample-autodetect

Contexterror
Could not detect any camera No camera auto detected.

nvidia@tegra-ubuntu:~/Desktop/Canon I have a Canon EOS 5DSR but it doesn't see it.

ok updating libusb-dev and some other dependencies solved the problem. ./sample-autodetect worked.

but I don't have : "gphoto2 the command line (CLI) interface to libgphoto2." how do I get it ?

The gphoto2 commandline tool is an additional repo which needs to be seperately built, see github.com/gphoto/gphoto2

ok but when I compile gphoto2 it links to the libgphoto2 version from the apt-get and not the one that I compiled using this git. https://github.com/gphoto/gphoto2/issues/206
