=== Makefile (shell, CLI)
Here is an example of creating a simple Debian package from a POSIX shell CLI program using the *Makefile* as its build system.
Let's assume its upstream tarball to be *debhello-1.0.tar.gz*.
This type of source is meant to be installed as a non-system file as:
----
$ tar -xzmf debhello-1.0.tar.gz
$ cd debhello-1.0
$ make install
----
Debian packaging requires changing this "`*make install*`" process to install files to the target system image location instead of the normal location under */usr/local*.
Let's get the source and make the Debian package.
.Download *debhello-1.0.tar.gz*
----
include::../examples/debhello-1.0_build-1/step000.slog[]
----
Here, the *Makefile* uses *$(DESTDIR)* and *$(prefix)* properly. All other files are the same as in "`<<nomakefile>>`" and most of the packaging activities are the same.
.*Makefile* (v=1.0)
----
include::../examples/debhello-1.0_build-1/step102.slog[]
----
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.
----
include::../examples/debhello-1.0_build-1/step200.slog[lines=1..3]
...
include::../examples/debhello-1.0_build-1/step200.slog-sanity[]
...
----
Let's inspect the notable template files generated.
// .The source tree after the basic *debmake* execution. (v=1.0)
// ----
// include::../examples/debhello-1.0_build-1/step201.slog[]
// ----
.*debian/rules* (template file, v=1.0):
----
include::../examples/debhello-1.0_build-1/step202.slog[]
----
Let's make this Debian package better as the maintainer.
.*debian/rules* (maintainer version, v=1.0):
----
include::../examples/debhello-1.0_build-1/step301.slog[]
----
Since this upstream source has the proper upstream *Makefile*, there is no need to create *debian/install* and *debian/manpages* files.
The *debian/control* file is exactly the same as the one in "`<<nomakefile>>`".
There are several other template files under the *debian/* directory. These also need to be updated.
.Template files under *debian/*. (v=1.0):
----
include::../examples/debhello-1.0_build-1/step400.slog[]
----
The rest of the packaging activities are practically the same as the ones in "`<<nomakefile>>`".
