25 == License
26 The licenses of this project are split into two parts:
27 1) the AudioManagerDaemon, licensed under MPL 2.0
28 2) all other parts that serve as example code that can be taken to build up an own project with it -
29     these parts are licensed with the MIT license
30     
31 Contribution is done under GENIVI CLA or MPL2.0. 
32
33 == Version
34 The current version can be taken out of the git. The version 1.0.0 is the first GENIVI compliant code,in the compliance statement of discovery (2.0). 
35 For every GENIVI release, there is a release of the AudioManager, each of the releases have an own bugfix branch that will get the most important fixes.
36 Development is done on the master branch.
37
38 === Versioning Scheme
39 The versioning scheme was decided in the February face2face 2012.
40 The firs number describes the release branch. This is 1 for discovery, 2 for excalibur and 3 for photon. For major features or release, the second number will be increased.
41 Each new GENIVI version (releases are every half year, around april and october) will get the current HEAD (for example 2.0.34 for excalibur) and release with the increase of the second number (2.1).
42 The next commit on the master branch gets then the new first numner (3) and starts from zero.
43
44 For the daemon the third number (for example 1.0.X) describes the patch version. The versions are automatically created by git during the build process.
45 The versioning scheme is used for the AudioManager daemon itself and for each of it's interfaces. The versioning of the Interfaces in EA is defined via the tag "version" and the name of the interfaceversion versionName, for example "CommandReceiveVersion". This information is generated into the interface header files and is used then by cmake to set the interface versions.
46 Whenever changes are done, the minor version of the interface needs to be incremented.
47
48 == Documentation
49 A very detailed documentation is provided by doxygen. In order to use this, please compile the AudioManager with
50 ----
51 cmake -DWITH_DOCUMENTATION=ON

86 === Passing options to cmake:
87
88 .-DVERSION="XXX"
89 When building the AudioManager without taking it from the git (and thus having a .git folder), you can set the version via passing _-DVERSION="XXX"_ to cmake.
90
91 .-DDBUS_SERVICE_PREFIX="XXX"
92 sets the service prefix for Dbus, default "org.genivi.audiomanager\0"
93
94 .-DDBUS_SERVICE_OBJECT_PATH="XXX"
95 sets the object path for Dbus, default "/org/genivi/audiomanager\0"
96
97 .-DDEFAULT_TELNETPORT="XXX"
98 sets the default telnetport, default 6060. Can be overwriten by command line parameter
99
100 .-DMAX_TELNETCONNECTIONS="XXX"
101 sets the default maximum number of telnetconnections, default is 3
102
103 .-DNSM_PATH="XXX"
104 sets the path of the NSM DBUS interface
105
106 .-DNSM_INTERFACE="XXX"
107 sets the interface to the NSM DBUS interface
108
109 In order to change these options, you can modify this values with ccmake, do the appropriate changes in 
110 CmakeList.txt or via the commandline for cmake or (when installed via ccmake)
111
112 === Build dependencies
113 Basically, all build dependencies are optional- but you might need to use some if you want to have support for Dbus,
114 for example...
115
116 You will need optionally fullfill some dependencies in order to comile the GENIVI AudioManager Daemon, these are:
117
118 * dbus (only when DBUS_WRAPPER==ON) [tested on version 1.2.16]
119 * sqlite3 [tested on version 3.6.22] (only when WITH_DATABASE_STORAGE==ON)
120 * automotive-dlt [greater 2.5.0] (only when WITH_DLT==ON)        
121 * doxygen (only when WITH_DOCUMENTATION==ON) [tested on version 1.6.3]
122
123 To install them in a build environment like Ubuntu you can use:
124 ----
125 sudo apt-get install libdbus-1-dev libsqlite3-dev doxygen git cmake build-essential
126 ----
127
128 === The NodeStateManager
129
130 The nodestatemanager headers are needed to compile the audiomanager. If the nodestatemanagerincludes are not found, 
131 the headers shipped with the audiomanager are used.
132 The nodestatemanager can be retrieved from projects.genivi.org . You can install the headers on you system by
133
134 ----
135 sudo make install-includeHEADERS
136 ----
137
138 For building the tests, you will need the following packages:
139
140 * python [tested on version 2.6, should work on higher versions as well]
141
142 GoogleMock and GoogleTest are as source code integrated in the sourcetree
143 To install them in a build environment like Ubuntu you can use:
144 ----
145 sudo apt-get install python2.6-dev
146 ----
147
148 For compiling, you will need a compiler, linker etc. On most linux systems you will get this via
149 ----
150 sudo apt-get install build-essential
151 ----
152
153 More details in the CMake Files CmakeList.txt in the projects.
154
155 === Compiling
156 To compile open a shell, browse to the AudioManager folder and 
157 ----
158 mkdir /build
159 cd build
160 cmake ..
161 make
162 ----
163
164 After the script finished, you should have:
165
166 * a bin/ folder which contains all executables and the libraries: 
167 * a build/ folder which has all build objects (erase that if you need a clean build)
168 * a doc/ folder in case you turned the documentation on
169
170 In order to install the AudioManager, you can do
171 ----
172 sudo make install
173 ----
174
175 Package generation is supported via CPack. To build packages, you have to 
176 ----
177 make genivi_package
178 ----
179
180 This will create one package if your CMake version is < 2.8.5 (all binaries stripped):
181 ----
182 AudioManager-<git verison>-Linux.deb 
183 ----
184
185 If your version is above 2.8.5, you will get 4 packages (all binaries stripped) :
186         
187 * AudioManager-<git verison>-Linux-bin.deb              [AudioManager binary]
188 * AudioManager-<git verison>-Linux-dev.deb              [header files needed to compile plugins]
189 * AudioManager-<git verison>-Linux-sampleplugins.deb    [sample plugins]
190 * AudioManager-<git verison>-Linux-tests.deb            [tests including tests for sample plugins, installed in the ~/AudioMAnagerTests]
191
192 In order to create a tar.gz file of all sources (not including .git, build and bin folder,config files), you can do:
193 ----
194 make package_source                     
195 ----
196
197 This will create the following package:
198 'AudioManager-<git verison>-Source.tar.gz'
199
200 All packages will be placed in a folder called packages
201
202 === Adding own plugins
203 Since the AudioManager needs to be completed with on plugins before it can be used, it provides a mechanism to keep the own sources away from the GENIVI code but compile them together.
204
205 TIP: Using this feature is simple: +
206 Just add a folder with the name _ProjectSpecific_ (be sure to name it excactly like this!) on the main level of the AudioManager folder. CMake will look for CMakeLists.txt in this folder and add all files that it finds in /include to the include path. You can use this to add subfolders with your own plugins and includes, and overwrite productspecific.h for example.
207
208 .Here is a sample CMakeLists.txt that can be placed in ProjectSpecific folder:
209 ----
210 cmake_minimum_required(VERSION 2.6)
211
212 ### set your own buildflags:
213 set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -Wall -Wextra -std=c++98 -D_GNU_SOURCE -pedantic -Wno-variadic-macros")
214
215 ##overwrite priojecttypes.h:
216 CONFIGURE_FILE( ${CMAKE_SOURCE_DIR}/ProjectSpecific/overwrite/projecttypes.h ${CMAKE_SOURCE_DIR}/include/projecttypes.h COPYONLY)
217
218 if(WITH_PLUGIN_ROUTING)
219         add_subdirectory (../PluginRoutingInterfaceMyRoutingPlugin ${CMAKE_CURRENT_BINARY_DIR}/PluginRoutingInterfaceMyRoutingPlugin )
220 endif(WITH_PLUGIN_ROUTING)
221
222 if(WITH_PLUGIN_CONTROL)
223         add_subdirectory ( ../PluginControlInterfaceMyControlPlugin ${CMAKE_CURRENT_BINARY_DIR}/PluginControlInterfaceMyControlPlugin)
224 endif(WITH_PLUGIN_CONTROL)
225
226 ----
227
228 === CommandLine options
229 The commandline options of the AudioManager:
230
231 ----
232 AudioManagerDaemon Version: 3.0.11
233 Usage:  AudioManagerDaemon [options]

249
250
251 == Telnet Server
252 The audiomanager has a build- in telnetserver that serves for debuggin purposes.
253 If you compile your AudioManager with TelnetServer support (cmake -DWITH_TELNET=ON), you will be able to 
254 set with commandline argument -t the port number and with -m the maximum supported connections. 
255 The default telnet port is 6060. 
256    
257 .For example, launch a telnet session on port 6060:
258       telnet localhost 6060
259    
260       #>Welcome to GENIVI AudioManager ver-0.0.1-37-ga004215

320 == Code Formatting
321 The source code if formatted with eclipse, the style sheet used can be found in the cmake folder:
322 ----
323 cmake/AudioManager_Codestyle.xml
324 ----
325
326 == Working on the code & contribution
327
328 .First get the code from the git:
329         git clone 
330
331 .Get an overview of all branches:
332         git branch
333
334 .Switch to the branch you want to work on (see versioning schmeme, the master is the feature branch) and verify that it has switched (* changed)
335         git checkout <your branch>
336         git branch
337
338 .Best practice is to create a local branch based on the current branch:
339         git branch working_branch
340
341 Start working, best practice is to commit smaller, compilable peaced during the work that makes it easier to 
342 handle later on.
343
344 .If you want to commit you changes, send them to the audiomanager-dev list, you can create a patch like this:
345         git format-patch working_branch <your branch>
346
