Technical Preview for the OMNeT++ Community Summit 2021

This repository shows some advanced use cases for the OMNeT++ CMake package, including:

• Managing of complex dependencies like INET
• Using functions like add_opp_target to automatically add an OMNeT++ structured folder as a CMake target
• Using add_opp_run to create a debug configuration for Visual Studio Code
• Managing CMake based dependencies

VS-Code Plugins

Developing with VS-Code is done easily with the following plugins:

• ms-vscode.cpptools for C/C++ language support
• twxs.cmake for CMake language support
• ms-vscode.cmake-tools for CMake project integration
• schrej.omnetpp-ned for OMNeT++ NED language support
• vadimcn.vscode-lldb (CodeLLDB) for debugging C++ applications

Setting up the build environment on Windows with VS-Code

You simply can instruct the VS-Code CMake extension about your OMNeT++ compiler paths by adding a 'cmake-kits.json' file similar to the following example:

[
    {
        "name": "CLang Omnet++ 6.10 with .venv",
        "environmentSetupScript": "${workspaceFolder}/.vscode/omnetpp-6.0pre10env.cmd", 
        "compilers": {
            "C": "path/to/omnetpp-6.0pre10/tools/win64/mingw64/bin/clang.exe",
            "CXX": "path/to/omnetpp-6.0pre10/tools/win64/mingw64/bin/clang++.exe"
        }
    }
]

where the script omnetpp-6.0pre10env.cmd is optional and can help to initialize the build environment:

set PATH=%PATH%;path\to\omnetpp-6.0pre10\tools\win64\mingw64\bin
set PATH=%PATH%;path\to\omnetpp-6.0pre10\bin
set PATH=%PATH%;path\to\omnetpp-6.0pre10\tools\win64\opt\mingw64\bin
set PATH=%PATH%;path\to\omnetpp-6.0pre10\tools\win64\usr\bin
set PATH=%PATH%;path\to\omnetpp-6.0pre10\lib

rem Optional: Activate a python virtual environment (CMake will then use the corresponding interpreter)
set current_dir="%~dp0"
call %current_dir%..\.venv\Scripts\activate.bat
