RELEASE NOTES: OpenJAUSv3.3 (07/10/08) ========================================== OpenJAUSv3.3 beta is an open source implementation of the JAUS Reference Architecture Version 3.3. The latest code, documentation and support groups are available at the OpenJAUS web site: http://www.openjaus.com/. This release contains the following projects: libjaus: A C99 compliant library that contains JAUS constructs, data types and messages. libopenJaus: A C/C++ library containing a runtime JAUS node manager library, node manager communication interface, and component framework library. ojNodeManager: The OpenJAUS node manager executable with text interface ojVehicleSim: A collection of JAUS components that work together to simulate a JAUS ground vehicle subsystem. These components provide a set of services that are commonly used in real ground vehicle implementations. If you experience problems in compiling or developing with this code, please read the tutorials and online FAQ before contacting the OpenJAUS development group. Please attempt to locate where the problem exists and determine how the problem can be replicated before seeking additional support. Code patches can be uploaded at the OpenJAUS web site: http://www.openjaus.com. Target Operating Environment: ----------------------------- This software is designed to be cross platform compatible. The code base has been tested on a variety of operating systems and development environments including: Linux (Ubuntu & Fedora Core) w/gnu toolchain, Mac OS X w/gnu toolchain, and Windows w/MS Visual Studio. All test machines have been little endian byte order based. The libjaus library is C99 compliant and should be compatible with any standard C compiler for any processing platform. The libopenJaus library has some operating system dependent abstractions, which may require different implementations for systems not using Linux or Windows. The library was implemented with POSIX standard programming interfaces where applicable, to provide a more standardized approach to multi-threading and mutex implementation. Installation (GNU Toolchain / Linux & Macintosh OS X): ------------------------------------------------------ Requirements: make gcc g++ To build the library and executable code: Execute the command: "make" in the root OpenJAUSv3.3.0 directory. The make command will use the Makefile found in that directory to recursively make each of the subprojects. Individual Makefiles are located in each subproject directory to allow for building one project at a time if desired. Installation: It is up to the individual developer to decide how to link their code with the OpenJAUS libraries. Some developers may prefer to install the OpenJAUS header files and libraries to globally accessible directories. For example, on a Linux system: /usr/include/ and /usr/lib/. To minimize system invasiveness, OpenJAUS does not install itself into system directories, rather, all code and binaries remain in the folders included in the release download. To execute code developed with these libraries it is recommended that the developer configure the dynamic linker runtime bindings to reference the OpenJAUS library directories /libjaus/lib/ and /libopenJaus/lib/. This is done by editing the systems ld.so.conf (most likely located at /etc/ld.so.conf) to include these directories and then by running the command: "ldconfig". Another option to this method would be to simply include the files libjaus.so and libopenJaus.so in the executable's working directory. *Note: The default build of the libraries includes all symbols and debug information within the shared object (.so) files. This is to facilitate efficient development and use of a run-time debugger. To reduce the size of the installed libraries, the information can be removed by using the "strip" command. Installation (Microsoft Visual Studio / Windows): ------------------------------------------------------ Requirements: Microsoft Visual Studio Pthreads-win32 (included in distribution) pdcurses (included in distribution) To build the library and executable code: In the top level directory, open the Microsoft Visual Studio solution file "OpenJAUSv3.3.0.sln." This solution contains 4 individual projects: libjaus, libopenJaus, ojNodeManager and ojVehicleSim. These projects correspond to the descriptions above. Once open, the solution should be able to be built. Each project has the appropriate dependencies setup using relative paths, therefore it should compile for the developer in any configuration. Also, project references have been setup, so a referenced code base will be compiled prior to the compilation of any child project. Once built, the ojNodeManager should run in a console window if it is set as the default project. Ensure that the nodeManager.conf file is configured correctly. The ojVehicleSim should run as well if it is set to the default project, however it is important that the ojNodeManager be running first. The libraries libjaus and libopenJaus can be linked against other projects using the .lib files. To run projects built against them, ensure the appropriate .dll files are available either locally or globally on the system. *Note: Use of these libraries has only been tested in the Debug configuration to date. This is due to the added value of retaining debug information for developers of both the OpenJAUS code base and applications based upon that. The creation of release targets, if desired, is left up to the individual developer. Configuring and Running the Node Manager: ----------------------------------------- The node manager executable is currently designed to require manual configuration. This means the user must edit the text file nodeManager.conf to enter the appropriate JAUS identification numbers and names, and enter the correct IP addresses for the intended hardware communication interfaces. The user is also required to configure the node manager to enable or disable node level and subsystem level communication. These configurations will vary depending on the intended design of the JAUS system on which the node manager is being used. Examples of different JAUS system setups are beyond the scope of this document. The user is encouraged to read the JAUS reference architecture and online OpenJAUS tutorials for a more detailed explanation. Format: The nodeManager.conf file is made up of section tags and key - value pairs. The tags are identified within straight braces, ex: "[SECTION]". The key value pairs are delimited by a colon and a space character, ex: "key: value". To configure the JAUS node manager properties, edit the "SubsystemId" and "NodeId" values found under the [JAUS] section tag. Each node manager on a subsystem's node network should be configured with a unique NodeId number. Likewise each subsystem on a network of JAUS subsystems should have a unique SubsystemId number. Failure to make these values unique results in erratic and undefined behavior when multiple node managers are running at the same time. Only one node manager process should be run at any given time on a single node. Set the "Subsystem_Identification" and "Node_Identification" values to any text string that you would like for your particular system setup. These values are not required to be unique, as they are only used for text description. To configure communication interface settings the user is only required to edit the [Node_Communications] and [Subsystem_Communications] sections. By default, component communications are always on and the configuration needs to be kept fixed to use the loopback IP address 127.0.0.1. Each communications section has one or more sets of transport interfaces settings, for example "JAUS_UDP" and "OpenJAUS_UDP". This allows for multiple transport interfaces to be used at a given communications level (component, node, or subsystem). At present only the JAUS_UDP interface type is used at the node and component level. However, this allows for other common transport types such as TCP or Serial to be included in the future. The user has the option to enable/disable a given transport interface, or enable/disable an entire level of communication either node or subsystem. The node manager will startup a transport interface if both it and its communications level is enabled. To enable a communications level, simply set the value of the "Enabled" key to "true". To disable a level, set the value to "false". These values are case sensitive, ex: "TRUE" or "True" would not work. When each JAUS_UDP interface starts, it attempts to open the network interface specified with the user configured IP address. If such an interface exists on the system, the node manager will open the JAUS port 3794 on that interface. If not, the node manager will fail at startup and an error message will appear. To configure each JAUS_UDP interface simply set the key "JAUS_UDP_IP" value to the IP address of the network interface that you would like it to use. The remaining key values should be left configured as in the release download. Changing these values will lead to undefined behavior. They are included only for completeness, and allow for future changes to be made if necessary.

Please read the tutorials for detailed information on how to perform common tasks. The header files are organized by function breakdown and allow for easy access to data structure definitions and function prototypes. Often the functions you seek can be found quickly by browsing the include/ directories.
