If you want to contribute to the UERANSIM. Here you can find some development guidelines.

C++ Coding Style

  • This UERANSIM-specific coding style guideline shall be used inside of the UERANSIM project.
  • Do not use C language, and don't write C-style codes. Use modern and rich C++ features instead.
  • Use Microsoft's C++ coding guidelines, with following exceptions:
    • Use AlwaysBreakTemplateDeclarations: Yes (for clang tidy)
    • Use camelCase for instance methods, PascalCase for static functions.

Development Environment

It is recommended to use Clion as an IDE.

  1. Start Clion C++ IDE
  2. Click Open
  3. Select the root folder of UERANSIM and hit OK
  4. Clion will ask you if you want to import the project as CMake or makefile. Select CMake.
  5. Click Build/Build Project from the top menu.

Build and Compile

Build instructions written in Installation Wiki is not required for developers. You should be able to build normally inside of Clion C++ IDE. You can also build in Debug mode, and/or utilize the debugger.

If you add, remove or rename a source file, make sure that you click Reload CMake Project from the menu, before building the project.
