• Runs cppcheck on the fly while you write code.
• Highlights lines and displays cppcheck error messages.
• Supports passing options to cppcheck.

This project is supported with a free open source license of CLion from JetBrains.

Installation

See Installing, Updating and Uninstalling Repository Plugins

• cppcheck in JetBrains Plugin Repository

Usage

1. Install the cppcheck tool using the instructions on its homepage. This plugin does not bundle the cppcheck tool itself, which must be installed separately.
2. Install the cppcheck plugin into CLion.
3. Configure the plugin with the absolute path to the cppcheck executable into the cppcheck path option.
   1. Windows
      1. File | Settings | Cppcheck configuration
      2. Usually the path is C:\Program Files (x86)\Cppcheck\cppcheck.exe
   2. macOS:
      1. CLion | Preferences | Cppcheck configuration
      2. In a terminal run which cppcheck to find the path to cppcheck. If you installed it with Homebrew, the path will be /usr/local/bin/cppcheck.
   3. Linux
      1. File | Settings | Cppcheck configuration
      2. In a terminal run which cppcheck to find the path to cppcheck. If you installed it with your system's package manager, it is probably located at /usr/bin/cppcheck.

Known Issues

cppcheck is not designed to be run on header files (.h) directly, as must be done for this plugin, and as a result may have false positives.

When run on header files directly, cppcheck defaults to C as the language, which will generate false positives for C++ projects. C++ projects should append --language=c++ to the cppcheck options.

Development

To run the plugin from source, open this project in IntelliJ and create a new "Plugin" run configuration. Running or debugging this run configuration will launch a new IntelliJ process with the plugin loaded into it.
