Serval DNA Build and Test
=========================

To build
--------

Run the following commands:

    autoreconf -f -i
    ./configure
    make

On Solaris, the system `make` command may not be GNU Make, and the system
`cc` command may not be GNU Gcc.  The following may work:

    autoreconf -f -i
    CC=gcc ./configure
    CC=gcc gmake

Supported Targets
-----------------

The Serval DNA code successfully builds for the following platforms:

 * Debian Linux, ix86 and x86\_64, kernels 2.6.x and 3.x, [gcc 4.4][] to [gcc 4.7][]
 * [Android 2.2 “Froyo”][], Arm, Linux kernels 2.6.x and 3.x, [gcc 4.4][] supplied as
   part of [Android NDK][] Revision 7b
 * Mac OS X 10.7 “Lion”, x86\_64, [gcc 4.2][] available in [Xcode 4][] 3.2.6
 * Oracle SunOs 5.10 (Solaris), Sparc, [gcc 4.4][]

Dependencies
------------

The dependencies for build are expressed in [configure.in](./configure.in).
Most mandatory dependencies are present by default in a conventional Linux
development environment.

Mandatory dependencies:

 * standard C library `libc` and standard headers
 * standard math library `libm` and headers `<math.h>` `<float.h>`
 * network services library `libnsl` and headers
 * socket library `libsocket` and headers
 * dynamic link library `libdl` and header `<dlfcn.h>`
 * Native Posix Threads Library `libpthread` and header `<pthread.h>`
 * on Solaris, the realtime library `librt` (for the `nanosleep()` function)

Optional:

 * Java compiler and SDK (mandatory for Android's **libservald.so**)
 * ALSA sound library and headers (only present on Linux not Android)

Built artifacts
---------------

The build process produces the following artifacts:

* **servald** is the main executable.

* **libservald.so** is a shared library built only for Android, which is linked
  into the [batphone][] Java executable at run time to provide the [JNI][]
  entry points to servald.

* **directory_service** is the executable for the Serval Infrastructure daemon.

* **libmonitorclient.a** and **libmonitorclient.so** are libraries implementing
  the client end of the monitor interface with the servald daemon.  They are
  linked into the [batphone][] Java executable at run time and contain [JNI][]
  entry points to functions for managing the client end of a monitor connection
  with the servald daemon.

Voice call test
---------------

If the following packages are present then `./configure` will set the
`HAVE_VOIPTEST` macro and build **servald** with its `phone` command available
for performing voice call testing:

 * [Port audio](http://www.portaudio.com)
 * [Secret Rabbit Code](http://www.mega-nerd.com/SRC/) (a.k.a. Sample Rate
   Convert) by Erik de Castro Lopo
 * [SpanDSP](http://www.soft-switch.org/) by Steve Underwood
 * [Codec2](http://www.rowetel.com/blog/?page_id=452) by Dave Rowe of Rowetel

The Codec2 source code can be fetched using [Subversion][]:

    svn checkout https://freetel.svn.sourceforge.net/svnroot/freetel/codec2 codec2

The following options can be used to control the `HAVE_VOIPTEST` macro:

 * `./configure --enable-voiptest` will set `HAVE_VOIPTEST` and fail if the
   necessary packages are not present

 * `./configure --disable-voiptest` will unset `HAVE_VOIPTEST` and will not
   check for presence of the above packages

Test scripts
------------

The scripts in the [tests](./tests/) directory require [Bash][] version 3.2.48
or later.  To run all the tests (except long-running, resource-hungry stress
tests), build the `servald` executable natively using [GNU make][], then invoke
them manually:

    ./tests/all

There are options to run tests concurrently for faster results, and to select
subsets of test cases.  To see the options, give the `--help` option:

    ./tests/all --help

The logs of the most recent test run are in the [testlog/all](./testlog/all/)
directory.
