The first time you build the project all of the necessary files and sub-directories are created. From then on each time you build only the relevant files that need to be changed as a result of changes in the interface are modified.
Glade generates all the necessary files to be GNU compliant and to essentially run your application immediately (although without any callbacks the application won't do much). The primary location for your C source code is in a subdirectory called src. In there you will see 3 header files (support.h, interface.h, and callbacks.h) and 4 source files (support.c, interface.c, callbacks.c, and main.c). Of these you should never edit support.h, support.c, interface.h, and interface.c. The first pair contain code that Glade supplies to support your application and the latter two are the actual interface code. Glade manages these files. You will be making changes primarily in callbacks.c to add the code for each callback. Glade will add new callbacks to the bottom of callbacks.h and callbacks.c.
Now that you have built your interface (perhaps without any callback code just yet) you are in a position to configure, compile and run your application. The GNU automake and autoconf packages are used to simplify the management of the configuration, compilation, and installation of your application. These packages are a great help in the task of managing software projects.
Discuss the files generated by the build and how they conform to the GNU Standards.
