Serval DNA Build and Test

Serval Project, March 2013

Supported Architectures

These instructions will build Serval DNA successfully for the following platforms:

Debian Linux, ix86 and x86_64, kernels 2.6.x and 3.x, using gcc 4.4 to [gcc 4.8][]
Mac OS X 10.7 “Lion”, x86_64, using gcc 4.2 available in Xcode 4 3.2.6
Oracle SunOs 5.10 (Solaris), Sparc, using gcc 4.4

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)

Download

Serval DNA source code is available from the serval-dna repository on GitHub. You can use Git to download the latest version:

$ 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. 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>
Autoconf 2.67 or later
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)

Test dependencies:

bash 3.2.48 or later
jq 1.3 or later
curl

Build

To compile Serval DNA from source, run the following commands:

$ cd $HOME/src/serval-dna
$ autoreconf -f -i
$ ./configure
$ make
$

A successful session should appear something like:

$ cd $HOME/src/serval-dna
$ autoreconf -f -i
$ ./configure
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for gcc... gcc
...
checking for library containing strlcpy... no
configure: creating ./config.status
config.status: creating Makefile
config.status: creating testconfig.sh
$ make
CC nacl/src/crypto_auth_hmacsha256_ref/hmac.c
CC nacl/src/crypto_auth_hmacsha256_ref/verify.c
CC nacl/src/crypto_auth_hmacsha512256_ref/hmac.c
...
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
$ CC=gcc
$ export CC
$ ./configure
$ gmake
$

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.

Test scripts

The scripts in the tests directory require Bash version 3.2.48 or later. To run tests, simply build a native servald executable then invoke the test script. Each test case is executed in its own self-contained temporary directory with its own set-up and configuration, so there is no need to configure anything or clean up afterwards.

For example, the following command runs all the tests except long-running, resource-hungry “stress” tests:

$ ./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
$

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

Every test run writes its log files into the testlog/all directory, deleting all logs from the previous run.

Configure

The doc/Servald-Configuration document describes the configuration of Serval DNA in detail.

About the examples

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.

The directory paths used in the examples are for illustrative purposes only, and may need to be changed for your particular circumstances.
