=== Introduction ===

This example requires a working configuration of MADDE. At least one target has to be installed and set as 'default'. The basic steps to do this are described in this [[MADDE/Configuration | guide]].

* start a project in MADDE
* use template-projects for developing
* compile a project in MADDE
* build a package

=== Templates ===

Templates are used in MADDE to simplify the set up of the basic skeleton for a project. The following command shows the list of available templates:

mad pscreate -l

:The command gives following output:

TEMPLATE NAME TYPE DESCRIPTION
empty prog Empty project
lib_simple lib Simple example for C/C++ libraries
qt_lib_simple qtlib Simple example for Qt libraries
qt_simple qtprog Simple example for Qt programs
simple prog Simple example for C/C++ programs

=== Start the project ===

The goal of this example is to create a simple GTK helloworld application. Therefore we can use the "simple" template out of the list with small modifications. The following command creates a project using the "simple" template and named as "helloworld"

mad pscreate -t simple helloworld

Afterwards the skeleton is created with the following subdirectories:

* '''src''': place for sourcefiles
* '''debian''':configuration files, which are needed to create the package later on
* '''uis''':empty folder for ui files which would be needed with Qt applications

Further it contains a file named "prog.pro", which is a [http://doc.trolltech.com/4.5/qmake-project-files.html project file], needed to create the Makefile with qmake.

Lets create a small GTK helloworld application hello.c in src directory:

#include <gtk/gtk.h>
static void destroy( GtkWidget *widget,
gpointer data )
{
gtk_main_quit ();
}
int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *label;
gtk_init (&argc, &argv);
label = gtk_label_new("Hello world");
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (G_OBJECT (window), "destroy",
G_CALLBACK (destroy), NULL);
gtk_container_add (GTK_CONTAINER (window), label);
gtk_widget_show (window);
gtk_widget_show(label);
gtk_main ();
return 0;
}

=== Compile & build ===

Before we can compile GTK application we have to modify prog.pro file.
In prog.pro file edit SOURCES += and HEADERS += lines to contain source files in the project, in our case wee need only following line:
SOURCES += hello.c

For GTK applications we want to use pkgconfig to help compiling and linking against correct libraries.

For our example we add following lines:
CONFIG += link_pkgconfig
and
PKGCONFIG += gtk+-2.0

Now we are ready to build our application.

The following steps describe how to compile and build the project.

1. Create the Makefile:

cd helloworld
mad qmake

2. Compile the project.

mad make

:Now the executable program helloworld is created in the helloworld/build directory.

3. Create a debian package:

mad dpkg-buildpackage

:This command will build the project and make a debian package called helloworld_0.1_armel.deb. The debian package will be created in the projects' parent directory.
