Valgrind Memcheck is a tool for detecting memory-usage problems such as leaks, invalid memory access, incorrect freeing, and referencing undefined values.
Install Valgrind on your system.
For WSL, install Valgrind on your WSL instance (
sudo apt-get install valgrind) and provide CLion with the path to the executable (see next steps).
In CLion, go to.
CLion will attempt to detect the Valgrind binary by searching in standard locations defined in the system
In case of a non-standard Valgrind location, set the path manually in the Valgrind executable field.
Specify analysis options or use the default ones.
Optionally, configure the list of the suppression files. For example, you may want to add a suppression file to turn off the Valgrind checks for some particular libraries.
Configure Valgrind on WSL
To use Valgrind on Windows via WSL, provide the 'subsystem' path to Valgrind, which is /usr/bin/valgrind by default, instead of the actual Windows location of the Valgrind binary. However, this path will not be valid until you select the CMake profile connected to the WSL toolchain. For this, do one of the following:
Set the WSL toolchain as default. This way, it will automatically connect to the default CMake profile:
Create a separate CMake profile, connect it to the WSL toolchain, and select this profile in the configurations switcher:
To run a target (application or test) with Valgrind Memcheck, do one of the following:
Click the gutter icon and select Run 'your_target_name' with Valgrind Memcheck option from the menu:
Select the desired Run/Debug configuration and call from the main menu or click the dedicated toolbar icon:
If Valgrind was not configured previously, CLion will open the configuration dialog.
When the launch is finished, open the Valgrind tab in the Run tool window.
The left-hand pane shows the list of all problems found by Valgrind Memcheck. Each entry includes the instruction pointer, problematic function name, and (if possible) the source file where the problem is located.
In the right-hand pane, you can find full stack frame description and the corresponding code preview (when possible).
Export and import results
To export the results, click the Export icon in the left pane of the Valgrind tab and specify the destination XML file:
Note that the Export button is unavailable during execution.
To import the results, selectfrom the main menu and choose the XML file to import from.
