Example Script does not detect my camera

[keplusplus]

I have an Canon EOS 1100D and the gphoto2 CLI-tool detects it corretly. But when I use your Example2-script, the output is "GPhoto couldn't detect any cameras connected to the computer".

I'm running on an Raspberry Pi Rev. 3. I already tried to uninstall evereything and reinstall it, but the output did not change. There is no error when compiling gphoto2pp.

And please add to your 2 minute tutorial that you have to include the "include" folder while compiling with "g++ -std=c++11 -o scriptname -I /path/to/gphoto2pp/include scriptname.cpp -lgphoto2 -lgphoto2pp". Or is there another way?

If you need more information I will send you.
Thanks for helping
