## We require gphoto2 lib and its wrapper.

### install gphoto2 library
* remove previous libgphoto versions

    sudo apt-get remove gphoto2 libgphoto2-6 libgphoto2-dev libgphoto2-l10n libgphoto2-port12 

* install libgphoto2 (oneline)
**source**: https://github.com/gonzalo/gphoto2-updater

    wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/gphoto2-updater.sh && wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/.env && chmod +x gphoto2-updater.sh && sudo ./gphoto2-updater.sh

### install gphoto2pp wrapper
* Clone the gphoto2pp wrapper
**source**: https://github.com/maldworth/gphoto2pp

    git clone https://github.com/maldworth/gphoto2pp.git

##### **refer**: Readme of the repo.

* run the following command in the directory.

    cd gphoto2pp
    ./cmake_release.sh

* run the following command in **build/release** directory.

    cd build/release
    make
    make examples
    sudo make install
    sudo ldconfig

## This concludes the installation of library and wrapper.

### Test the functionality:
* create a source file:

    touch testgphoto2pp.cpp

* add the following code into the **testgphoto2pp.cpp** file.

    #include <gphoto2pp/camera_wrapper.hpp> 		// Header for CameraWrapper
    #include <gphoto2pp/camera_file_wrapper.hpp>	// Header for CameraFileWrapper
    #include <gphoto2pp/helper_camera_wrapper.hpp>	// Used for helper::capture(...) method

    #include <iostream>

    int main()
    {
        // Connects to the first camera found and initializes
        gphoto2pp::CameraWrapper camera;

        // Prints out the summary of your camera's abilities
        std::cout << camera.getSummary() << std::endl;

        // Creates empty instance of a cameraFile, which will be populated in our helper method
        gphoto2pp::CameraFileWrapper cameraFile;

        // Takes a picture with the camera and does all of the behind the scenes fetching
        gphoto2pp::helper::capture(camera, cameraFile);

        // Lastly saves the picture to your hard drive
        // Your camera might take files in different formats (bmp, raw)
        // so this extension might be wrong and you should rename your file appropriately
        cameraFile.save("my-gphoto2pp-test.jpg");

        return 1;
    }

* run the following command.

    g++ -std=c++11 testgphoto2pp.cpp  -lgphoto2pp -lgphoto2

### connect the camera.

### Before executing the file, make sure the camera storage is unmounted from file system.

* run the command:

    ./a.out
