This is an application which allows the SD card inserted into the Pi to be copied to one in a connected USB reader. How to build ------------ 1. Install dependencies The dependencies of any Debian project are listed in the "Build-Depends" section of the file named "control" in the "debian" subdirectory of the project. If the project has already been released into apt, then the build dependencies can be automatically installed using the command "sudo apt build-dep <package-name>". 2. Prepare project To create the "configure" file and prepare the project directory, use the command "./autogen.sh" in the top directory of the project. If this file is not present, then instead use the command "autoreconf -i -f" followed by the command "intltoolize -c --automake --force", both in the top directory of the project. 3. Configure To configure the make system, use the command "./configure" in the top directory of the project. This will by default set the project for installation in the /usr/local tree, which will not overwrite a version which has been installed from apt. If you wish to overwrite a preinstalled version in the /usr tree, supply the arguments "./configure --prefix=/usr --libdir=/usr/lib/<library-location>" to the configure command. On a 32-bit system, <library-location> should be "arm-linux-gnueabihf". On a 64-bit system, <library-location> should be "aarch64-linux-gnu". 4. Build To build the application, use the command "make" in the top directory of the project. 5. Install To install the application and all required data files, use the command "sudo make install" in the top directory of the project.
