CLion 2021.2 EAP: Profiling on WSL, Fixes for CMake Presets, LLDB 12

The new CLion 2021.2 EAP (build 212.4535.17) is now available from our website, via the Toolbox App, or as a snap package for Ubuntu. If you are on macOS, there is a separate build for Apple Silicon M1 chip.


Here are the main highlights:

Profiling on WSL

CPU profiler integration previously only worked for local setups on Linux and macOS, and was enabled for remote mode in a previous EAP build. Now, it also works on WSL.

You will need a Perf backend, and you can only install it on WSL 2.

We hope that enabling profiling on WSL will help Windows users who are suffering from the lack of profiling abilities in CLion. In the future, we may also add a native profiler for our Windows users.

CMake Presets fixes

We’re continuing our work on CMake Presets in this release cycle. This time, we’ve added the following enhancements:

  • When you edit the preset in CLion (as a json file) or update it externally, CLion will notice the change and will suggest a CMake Reload to get the changes:CMake Presets Reload
  • On Windows, architecture and toolset properties from the configure preset are now passed to the CMake options in the CMake profile on import:Windows toolsets and arch

LLDB 12.0

CLion now bundles LLDB v12.0. Please let us know if you observe any issues with this debugger version.


You can now configure the colors that are used in Doxygen comments in Settings/Preferences | Editor | Color Scheme | C/C++ | Comments | Doxygen:
