CodeChecker support

CodeChecker is a static analysis infrastructure. It executes analysis tools available on the build system, such as Clang-Tidy, Clang Static Analyzer and Cppcheck. Refer to the analyzer’s websites for installation instructions.

Installing CodeChecker

CodeChecker itself is a python package available on pypi.

pip install codechecker

Building with CodeChecker

To run CodeChecker, west build should be called with a -DZEPHYR_SCA_VARIANT=codechecker parameter, e.g.

west build -b mimxrt1064_evk samples/basic/blinky -- -DZEPHYR_SCA_VARIANT=codechecker

Configuring CodeChecker

CodeChecker uses different command steps, each with their respective configuration parameters. The following table lists all these options.

Parameter	Description
CODECHECKER_ANALYZE_JOBS	The number of threads to use in analysis. (default: <CPU count>)
CODECHECKER_ANALYZE_OPTS	Arguments passed to the analyze command directly. (e.g. --timeout;360)

CODECHECKER_NAME	The CodeChecker run metadata name. (default: zephyr)
CODECHECKER_PARSE_EXIT_STATUS	By default, CodeChecker identified issues will not fail the build, set this option to fail during analysis.
CODECHECKER_PARSE_OPTS	Arguments passed to the parse command directly. (e.g. --verbose;debug)
CODECHECKER_PARSE_SKIP	Skip parsing the analysis, useful if you simply want to store the results.

These parameters can be passed on the command line, or be set as environment variables.

Running twister with CodeChecker

Parameter	Value
CODECHECKER_ANALYZE_JOBS	1
CODECHECKER_NAME	<board target>:<testsuite name>
