-----------------------
2014-02-14 07:23:31 +00:00
These instructions will build [Serval DNA][] successfully for the following platforms:
2014-02-14 07:23:31 +00:00
* Debian Linux, ix86 and x86\_64, kernels 2.6.x and 3.x, using [gcc 4.4][] to
[gcc 4.8][]

2014-02-14 07:23:31 +00:00
[Serval DNA][] also runs on the following platforms, to which these build
instructions do not apply:
* [Android 2.2 “Froyo”][], Arm, Linux kernels 2.6.x and 3.x, using [gcc 4.4][]
supplied as part of [Android NDK][] Revision 7b
* [OpenWRT][] (as used by the [Serval Mesh Extender][], the [Mesh Potato][],
and the [Commotion Wireless][] project)
2013-05-29 03:51:41 +00:00
Download
--------
Serval DNA source code is available from the [serval-dna][] repository on
2014-02-14 07:23:31 +00:00
GitHub. You can use [Git][] to download the latest version:
2013-05-29 03:51:41 +00:00
$ cd $HOME/src
$ git clone -q git://github.com/servalproject/serval-dna.git
$ cd serval-dna
$
Dependencies
------------
The dependencies for build are expressed in [configure.in](./configure.in).
2013-05-29 03:51:41 +00:00
Most mandatory dependencies are present in the standard 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)
* Autoconf 2.67-2.69 (2.70 may work but has not been tested)
* Automake 1.15
Optional:
* Java compiler and SDK (mandatory for Android's **libservald.so**)
* ALSA sound library and headers (only present on Linux not Android)
Test dependencies:
* bash 3.2.48 or later
* GNU grep, sed and awk (on OSX and Solaris, as ggrep, gsed and gawk)
* jq 1.3 or later
* curl
The GNU grep, sed and awk programs can be installed on OSX using the
[homebrew][] package manager. The [Notes for Developers](./doc/Development.md)
give more details.

Build
-----
To compile a native (ie, not cross-compiled) Serval DNA from source, run the
following commands:
2013-05-29 03:51:41 +00:00
$ cd $HOME/src/serval-dna
$ autoreconf -f -i -I m4
2013-05-29 03:51:41 +00:00
$ ./configure
$ make
$
A successful session should appear something like:
$ cd $HOME/src/serval-dna
$ autoreconf -f -i -I m4
aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'
2013-05-29 03:51:41 +00:00
$ ./configure

checking host system type... i686-pc-linux-gnu

checking for pkg-config... /usr/bin/pkg-config

$ make
SERVALD CC conf.c

CC cli.c
CC commandline.c
...
2013-05-29 03:51:41 +00:00
CC xprintf.c
LINK servald
LINK libmonitorclient.so
AR libmonitorclient.a
CC tfw_createfile.c
LINK tfw_createfile
$
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:
$ cd $HOME/src/serval-dna
$ autoreconf -f -i -I m4
2013-05-29 03:51:41 +00:00
$ CC=gcc
$ export CC
$ ./configure
$ gmake
$
In the event of a build failure, first consult the [Notes for
Developers](./doc/Development.md), then [contact the Serval Project][].
Built artifacts
---------------
The build process produces the following artifacts:
* **servald** is the main Serval DNA 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.
* **fakeradio** is a utility used by test scripts to simulate the serial
interface to the [RFD900][] packet radio used in the [Serval Mesh Extender][]
* **simulator** is a utility used by test scripts for simulating wireless
packet transmission under different conditions.
* **tfw_createfile** is a utility needed by test scripts for creating large
data files with unique, non-repeating content.
* **config_test** is a utility that will fail to link if any external
dependencies creep into the configuration subsystem.

Test scripts
------------
After building the native `servald` executable, run all the tests with the
following command:
2013-05-29 03:51:41 +00:00
$ ./tests/all
1 [PASS.] (logging) By default, only errors and warnings are logged to stderr
2 [PASS.] (logging) Configure all messages logged to stderr
3 [PASS.] (logging) Configure no messages logged to stderr
4 [PASS.] (logging) By Default, all messages are appended to a configured file
...
158 [PASS.] (rhizomeprotocol) One way direct pull bundle from configured peer
159 [PASS.] (rhizomeprotocol) Two-way direct sync bundles with configured peer
160 [PASS.] (directory_service) Publish and retrieve a directory entry
161 [PASS.] (directory_service) Ping via relay node
161 tests, 161 pass, 0 fail, 0 error
$
Every test run writes log files into the [testlog/all](./testlog/all/)
directory (relative to the current working directory), deleting any logs from
the previous run.
2013-05-29 03:51:41 +00:00
See [Serval DNA Testing](./doc/Testing.md) for more information on running and
developing test scripts.
2013-05-29 03:51:41 +00:00
Configure
---------
Before running `servald`, it must be configured correctly. The
[doc/Servald-Configuration](./doc/Servald-Configuration.md) document describes
the configuration of Serval DNA in detail.

About the examples
------------------
2013-05-29 03:51:41 +00:00
The examples in this document are [Bourne shell][] commands, using standard
quoting and variable expansion. Commands issued by the user are prefixed with
the shell prompt `$` to distinguish them from the output of the command.
Single and double quotes around arguments are part of the shell syntax, so are
not seen by the command. Lines ending in backslash `\` continue the command on
the next line.
2013-05-29 03:51:41 +00:00
The directory paths used in the examples are for illustrative purposes only,
and may need to be changed for your particular circumstances.
