Cppcheck Processor

Purpose

Runs cppcheck static analysis on C/C++ source files.

How It Works

Discovers .c and .cc files under the configured source directory, runs cppcheck on each file individually, and creates a stub file on success. A non-zero exit code from cppcheck fails the product.

Note: This processor does not support batch mode. Each file is checked separately because cppcheck performs cross-file analysis (CTU - Cross Translation Unit) which produces false positives when unrelated files are checked together. For example, standalone example programs that define classes with the same name will trigger ctuOneDefinitionRuleViolation errors even though the files are never linked together. Cppcheck has no flag to disable this cross-file analysis (--max-ctu-depth=0 does not help), so files must be checked individually.

Source Files

• Input: {source_dir}/**/*.c, {source_dir}/**/*.cc
• Output: out/cppcheck/{flat_name}.cppcheck

Configuration

[processor.cppcheck]
args = ["--error-exitcode=1", "--enable=warning,style,performance,portability"]
extra_inputs = [".cppcheck-suppressions"]   # Additional files that trigger rebuilds when changed

To use a suppressions file, add "--suppressions-list=.cppcheck-suppressions" to args.
