[[autotools-multi]]
=== Autotools (multi-binary)

Here is an example of creating a set of Debian binary packages including the executable package, the shared library package, the development file package, and the debug symbol package from a simple C source using the Autotools = Autoconf and Automake (*Makefile.am* and *configure.ac*) as its build system.  See <<autotools>>.

Let's package this in the same way as <<autotools-single>>.

Let's assume this upstream tarball to be *debhello-2.0.tar.gz*.

This type of source is meant to be installed as a non-system file, for example, as:

----
 $ tar -xzmf debhello-2.0.tar.gz
 $ cd debhello-2.0
 $ autoreconf -ivf # optional
 $ ./configure --with-math
 $ make
 $ make install
----

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

.Download *debhello-2.0.tar.gz*
----
include::../debhello-2.0-pkg1/step000.slog[]
----

Here, the contents of this source are as follows.

.*src/hello.c* (v=2.0):
----
include::../debhello-2.0-pkg1/step101.slog[]
----

.*lib/sharedlib.h* and *lib/sharedlib.c* (v=1.6):
----
include::../debhello-2.0-pkg1/step102.slog[]
----

.*Makefile.am* (v=2.0):
----
include::../debhello-2.0-pkg1/step103.slog[]
----

.*configure.ac* (v=2.0):
----
include::../debhello-2.0-pkg1/step104.slog[]
----

Let's package this with the *debmake* command into multiple packages:

* *debhello*: type = *bin*
* *libsharedlib1*: type = *lib*
* *libsharedlib-dev*: type = *dev*
* *debhello-dbg*: type = *dbg*
* *libsharedlib1-dbg*: type = *dbg*

Here, the *-b\',libsharedlib1,libsharedlib-dev,-dbg,libsharedlib1-dbg'* option is used to specify the generated binary packages.

----
sys::[head -n16  ../debhello-2.0-pkg1/step200.slog]
...
----

The result is similar to <<configure-single>> but with more template files.

Let's inspect notable template files generated.

.*debian/rules* (template file, v=2.0):
----
include::../debhello-2.0-pkg1/step202.slog[]
----

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

.*debian/rules* (maintainer version, v=2.0):
----
include::../debhello-2.0-pkg1/step301.slog[]
----

.*debian/control* (maintainer version, v=2.0):
----
include::../debhello-2.0-pkg1/step302.slog[]
----

.**debian/*.install** (maintainer version, v=2.0):
----
include::../debhello-2.0-pkg1/step303.slog[]
----

Since this upstream source creates the proper auto-generated *Makefile*, there are no needs to create *debian/install* and *debian/manpages* files.

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

.Template files under *debian/*. (v=2.0):
----
include::../debhello-2.0-pkg1/step400.slog[]
----

The rest of the packaging activities are practically the same as the one in <<configure-single>>.

Here are the generated dependency lists of binary packages.
