# [DESCRIPTION](#DESCRIPTION)

The gphoto2 library provides applications with access to a variety of cameras.

This man page will be extended with autogenerated documentation of the interface types and methods used for communication between the gphoto2 library and a frontend.

# [FILES](#FILES)

*~/.gphoto/settings*

Here gphoto2 applications may store their configuration used to access gphoto2.

To track down errors, you can add the **--debug** parameter to the **gphoto2** command line and, if dealing with USB problems, setting the environment variable **USB\_DEBUG=1**.

# [ENVIRONMENT VARIABLES](#ENVIRONMENT_VARIABLES)

[**CAMLIBS**](#CAMLIBS)

If set, defines the directory where the libgphoto2 library looks for its camera drivers (camlibs). You only need to set this on Windows systems and broken/test installations.

[**IOLIBS**](#IOLIBS)

If set, defines the directory where the libgphoto2\_port library looks for its I/O drivers (iolibs). You only need to set this on Windows systems and broken/test installations.

[**LD\_DEBUG**](#LD_DEBUG)

Set this to *all* to receive lots of debug information regarding library loading on **ld** based systems.

[**USB\_DEBUG**](#USB_DEBUG)

If set, defines the numeric debug level with which the libusb library will print messages. In order to get some debug output, set it to *1*.
