Cppcheck Lite

Cppcheck Lite is a minimalistic Visual Studio Code extension that runs cppcheck against C/C++ files upon save and reports any warnings or errors in the Problems panel.

Features

• On-save linting: When you save a c/cpp file, cppcheck is automatically run on that file.
• Per-file diagnostics: Only diagnostics relevant to the saved file are displayed.
• Configurable severity threshold: Filter out messages below a chosen severity level (info, warning, or error).
• Set C/C++ standard: Easily specify --std=<id> (e.g. c++17, c99, etc.).
• Diagnostic cleanup: When you close a file, its diagnostics are automatically cleared.

Requirements

Cppcheck must be installed on your system.

• By default, this extension looks for cppcheck on the system PATH.
• Alternatively, specify a custom executable path using the cppcheck-lite.path setting.

Examples of installing Cppcheck:

• On Linux (Debian/Ubuntu), install via sudo apt-get install cppcheck.
• On macOS with Homebrew: brew install cppcheck.
• On Windows, install from cppcheck's website.
