open-dis-cpp

A C++ implementation of the Distributed Interactive Simulation (DIS) application protocol IEEE-1278.

Note: This code base was originally auto generated with xmlpg.

Building Open DIS

• CMake is required to build the platform specific projects. It can be downloaded and installed from http://cmake.org/

• SDL2 and SDL2_net are required libraries to compile the examples. These can usually be install via Linux package managers. More details, and instructions for Windows are included below.

  NOTE: Windows users will need to either add the DLL folders to their path, or copy the DLLs to the output directory (Debug).

OpenDIS Build Options

The OpenDIS build system accepts several build options to control compilation. The following options are available:

• BUILD_SHARED_LIBS - Boolean value to specify whether to build OpenDIS libraries as shared (ON/TRUE) or static (OFF/FALSE). Default is ON.
• BUILD_EXAMPLES - Boolean value to specify whether to build example sender/receiver applications. Default is OFF.
• BUILD_TESTS - Boolean value to specify whether to build unit tests. Default is OFF.

Example application build options. Only valid if BUILD_EXAMPLES is enabled.

• SDL2_PATH - Installation path of SDL2
• SDL2_NET_PATH - Installation path of SDL2_net

These options are passed to cmake as arguments. Example: cmake -DBUILD_SHARED_LIBS=ON -DBUILD_EXAMPLES=ON ..

Linux / GNU Makefiles

1. Run mkdir build
2. Run cd build
3. Run cmake ..
4. Optionally, -DCMAKE_INSTALL_PREFIX=<custom-path-to-install> to set a custom directory to install the bin, include, and lib output directories.
5. Run make - this will output the libOpenDIS6.so, and libOpenDIS7.so libraries in the build directory along with the Example Applications.
6. The below steps are optional
7. Run make package to build Linux package files. Currently this will produce a Red Hat RPM package, Debian DEB package, and 2 compressed tarball (XZ, GZ).
8. Run make install to install bin, lib, and dir, into CMAKE_INSTALL_PREFIX WARNING: CMAKE_INSTALL_PREFIX default can to somewhere /usr/local/, if not specified with the -D flag as shown in Step 3.1. If you're unsure where to install, and want to keep your /usr/local/ directory clean, run cmake .. -DCMAKE_INSTALL_PREFIX=./install. This will cause make install to create a local install directory, from which you can move files elsewhere at a later date.

Windows with Visual Studio

1. Open CMake (cmake-gui) via the the start menu.
2. Enter the open-dis-cpp directory path into the Source and Build fields.
3. Click the + Add Entry button and enter the following details: Name: SDL2_PATH Type: PATH Value: <SDL2-install-folder> (if you follow the below SDL2 Windows Install Instruction this will be C:/SDL2)
4. Click the + Add Entry button and enter the following details: Name: SDL2_NET_PATH Type: PATH Value: <SDL2-install-folder> (if you follow the below SDL2 Windows Install Instruction this will be C:/SDL2)
5. Click the + Add Entry button and enter the following details: Name: CMAKE_LIBRARY_ARCHITECTURE Type: STRING Value: x64 (64 bit) or x86 (32 bit)
6. Click Configure and follow the prompts, selecting the correct generator (i.e. Visual Studio version).
7. Click Generate
8. Click Open Project - This should open the generates solution file in Visual Studio
9. Build the Solution (Ctrl + Shift + B)

These steps were tested with Visual Studio 16 2019 (Community Edition). Currently, only OpenDIS 6 and the Example Applications compile. The library and executable files are output to a Debug directory.

To run the executables, either the value of the SDL2_PATH/lib/CMAKE_LIBRARY_ARCHITECUTRE should be added to your path, or SDL2.dll and SDL2_net.dll need to be copied to the Debug directory.

Cleaning CMake files

To quickly clean up CMake output files, use git clean -xdf. Note: Use with care if you are actually developing open-dis-cpp, as git clean removes untracked files.

Old Pre-make build instructions

• premake5 is required to build the platform specific projects. Download it and make sure it's available on your path, or specify the path to it.

Linux / GNU Makefiles

1. Run premake5 gmake
2. Run make config=release

Windows with Visual Studio 2015

1. Run premake5 vs2015
2. Open the solution and build.

SDL2 and SDL2_net Install Instructions

Linux Package Managers

Arch: sudo pacman -S sdl2 sdl2_net

Fedora: sudo dnf install SDL2-devel SDL2_net-devel

Ubuntu: sudo apt-get install libsdl2-dev libsdl2-net-dev

If you're unable to install the correct packages, try installing from source

Windows Install Instructions

These are the installation steps that have been tested with open-dis-cpp, however there are other methods for installation. Experienced users should feel free to customise their install.

(Core) SDL2 Instructions

1. Navigate to the SDL2 Download page, and download the latest Development Libraries.

   Alternatively, the version tested with open-dis-cpp, 2.0.12-VC, can be downloaded from this direct link.

2. Extract the SDL2-devel-2.0.12-VC.zip file directly to your C:\.

3. Rename the resulting SDL2-2.0.12 folder to SDL2.

4. Add C:\SDL2\lib\x64 to your System Path for 64-bit systems, or add C:\SDL2\lib\x86 for 32-bit systems.

SDL2_net Instructions

1. Navigate to the SDL2_net project page, and download the latest Development Libraries.

   Alternatively, the version tested with open-dis-cpp, 2.0.1-VC, can be downloaded from this direct link.

2. Extract the SDL2-devel-2.0.12-VC.zip

3. Copy the include and lib directories from the resulting folder into you C:\SDL2\ folder
