=== Makefile (shell, GUI)

Here is an example of creating a simple Debian package from a POSIX shell GUI program using the *Makefile* as its build system.

This upstream is based on "`<<makefile-sh>>`" with enhanced GUI support.

Let's assume its upstream tarball to be *debhello-1.2.tar.gz*.

Let's get the source and make the Debian package.

.Download *debhello-1.2.tar.gz*

include::../examples/debhello-1.2_build-1/step000.slog[]
----

Here, the *hello* has been re-written to use the *zenity* command to make this a GTK+ GUI program.

.*hello* (v=1.2)
----
include::../examples/debhello-1.2_build-1/step101.slog[]
----

Here, the desktop file is updated to be *Terminal=false* as a GUI program.

.*hello.desktop* (v=1.2)
----
include::../examples/debhello-1.2_build-1/step102.slog[]
----

All other files are the same as in "`<<makefile-sh>>`".

Let's package this with the *debmake* command.  Here, the "`**-b':sh'**`" option is used to specify that the generated binary package is a shell script.

Let's inspect the notable template files generated.

Let's make this Debian package better as the maintainer.

Please note the manually added *zenity* dependency.

The *debian/rules* file is exactly the same as the one in "`<<makefile-sh>>`".

There are several other template files under the *debian/* directory.  These also need to be updated.

The rest of the packaging activities are practically the same as in "`<<makefile-sh>>`".

Here is the generated dependency list of *debhello_1.2-1_all.deb*.
