Info

Irrlicht for Linux requires a few additional libraries, which should already be installed in a typicaldesktop Linux installation. These include the X server, OpenGL, libpng, and libjpeg. Refer to the Irrlichtdocumentation for more information.CUSPhttp://www.dvs.tu-darmstadt.de/research/cusp/The CUSP website provides pre-compiled CUSP libraries for both Linux and Windows on x86 platforms(32 and 64 bit). Alternatively, CUSP may be built from the source code from the DVS SVN.The CUSP library depends on the GMP library 4 which may typically be installed via the packagemanager. For building the library you also need the MLton 5 Standard ML compiler and a GNU make 6environment including a C++ compiler.Boosthttp://www.boost.org/Parts of the planetp4v2 project depend on the Boost library, particularly on the smart pointer infrastructure7 .CMakehttp://www.cmake.org/The planetp4v2 project is a CMake based project. CMake does not build the the software directly butallows creating UNIX makefiles or project files for Microsoft Visual Studio or KDevelop. See section 4.5.2and the CMake documentation for more details.4.5.2 BuildingThis section briefly describes how to build the components for this project. We assume a Linux environmentfulfilling the requirements from 4.5.1. There are three parts of which each depends on the previousone. The first is about the CUSP library, followed by the main game project. The last part deals with thegame embedded in the CUSP simulator.CUSPBuilding CUSP from source is optional. The C++ bindings of the CUSP library are located in the subfoldercusp/cbindings/ of the BubbleStorm project. They are built simply calling make:cd /cusp/cbindingsmake4 http://gmplib.org/5 http://mlton.org/6 http://www.gnu.org/software/make/7 http://www.boost.org/doc/libs/1_40_0/libs/smart_ptr/smart_ptr.htm64 4.5 Usage
Output is the archive file libcusp.a. The corresponding C header file is generated as libcusp.h. As the CAPI is inconvenient to use, C++ wrapper classes provide an API that is similar to the original StandardML API. Thus, applications should always use the C++ header file cusp.h.planetp4v2planetp4v2 is a CMake project. Using the cmake command you can generate either Unix makefiles or setup a project for a common IDE like Microsoft Visual Studio, CodeBlocks, Eclipse CDT, or KDevelop. Forjust building the project, it is recommended to create a makefile and execute it:cd planetp4v2cmake .makeIf successful, this will generate the executable planetp4 and the archive for the simulator libplanetp4sim.a.Depending on the location of the BubbleStorm sources, the CMake project description file, CMake-Lists.txt, has to be adapted. The lineSET(TRANSPORT_DIR )specifies the (absolute or relative) path to the cbindings directory, e.g.SET(TRANSPORT_DIR ../../BubbleStorm/Middleware/cusp/cbindings)SimulatorThe Simulator build uses the libplanetp4sim.a and links it against the simulator core and setup code. Forbuilding the simulator there is a makefile, as usual.cd planetp4v2/simulatormakeSimilarly to the CMake project, the makefile contains the variable TRANSPORT_DIR specifying thelocation of the cbindings, e.g.TRANSPORT_DIR=../../../BubbleStorm/Middleware/cusp/cbindings4.5.3 Command Line ParametersThe planetp4 executable can run in client, server, and peer-to-peer mode as selected by command lineswitches. All available command line options are listed in the following table:Option Description Default-m, --mode Selects the networking mode. Available modes are p2p, p2pcuspserver, cuspclient, tcpserver, and tcpclient.-b, --bind-port Local UDP bind port number. 8585-s, --server Server or gateway peer address. -p, --server-port Server or gateway peer port number. 8585-c, --console Disables 3D rendering and runs the game in console mode. -a, --ai Enables AI player control (bot mode). -t, --terminate Terminates the game after the given number of milliseconds.4 Implementation 65
