CLion Project Configuration

CLion can integrate with CMake to provide code comprehension features.

After opening the serenity repository in CLion as a new project, the "Open Project Wizard" window will open, from here set the following fields:

(Assuming you use Ninja as the build system and configured the CMake build directory to Build/i686)

Build type: Default

CMake will complain with any other build type, make sure to use Default so that CMAKE_BUILD_TYPE is empty in the Build/i686/CMakeCache.txt file.

CMake Options: -G Ninja -DBUILD_LAGOM=ON -DCMAKE_C_COMPILER=gcc-10 -DCMAKE_CXX_COMPILER=g++-10

The gcc-10 and g++-10 are not special-meaning strings, they're paths to your GCC compiler executables, and should be findable through PATH. It is entirely possible you might have to instead use something like -DCMAKE_C_COMPILER=/opt/homebrew/bin/gcc-11 -DCMAKE_CXX_COMPILER=/opt/homebrew/bin/g++-11 instead of the above.

Build Directory: Build/i686

If you have not built the Toolchain at this point, please do so: ./Toolchain/BuildIt.sh

If you already have the project open, you can go to File -> Settings -> Build, Execution, Deployment -> CMake to find these options.

Remember to recreate the CMake cache after changing any of the options.

Excluding Build Artifacts

Source files are copied to the Build directory during the build, if you do not exclude them from CLion indexing they will show up in search results. This is often confusing, unintuitive, and can result in you losing changes you have made to files. To exclude these files navigate to the Project tool window, right-click the Build folder and select Mark Directory as | Excluded. If you want exclude Toolchain files as well, follow the same procedure with the following paths:

• Toolchain/Local
• Toolchain/Tarballs
• Toolchain/Build

Code Generation Settings

To make code generated by CLion (e.g. identifier names, const placement) match the SerenityOS coding style, change the following options under Settings -> Editor -> Code Style -> C/C++:

• On the Code Generation tab set const/volatile qualifier placement to int const x = 0

• On the Naming Convention tab, select the following:

  

Notes for WSL Users

It is possible to set the embedded terminal in CLion to the one that your WSL distribution provides. This way you can build and run serenity without leaving the IDE. Note that following will only help if you don't use an X-window server to access qemu. It is possible to install qemu natively on Windows and allow WSL to use it instead of installing qemu first on (wsl) linux and then use X server to launch serenity inside of it. Check the updated manual here.

• Locate the terminal emulator for your linux distribution. Open CMD with elevated privileges and cd to C:/Program Files/WindowsApps/. The directory is usually hidden and requires additional privileges. You should be able to cd as administrator. dir and look for your distribution in directory names. In case of Ubuntu, it starts with CanonicalGroupLimited.Ubuntu20.04onWindows_2004.2020.424.0_x64. cd to it. The directory should contain the shell executable. In my case it's named ubuntu2004.exe. Copy absolute/path/to/ubuntu2004.exe.

• Go to your IDE settings: File->Settings->Tools->Terminal and paste the path you just copied to shell path. Click OK.

• Close CLion and restart.

The default IDE terminal should now be changed to WSL, and now you can run CLion/run.sh. You may also want to copy serenity/Meta/CLion/run.sh to your project directory and run it from there, so that you don't have to fight with git every time you modify the script.
