Analyze given C/C++ files for common errors.
--check-config
Check Cppcheck configuration. The normal code analysis is
disabled by this flag.
--check-library
Show information messages when library files have
incomplete info.
-D<id>
By default Cppcheck checks all configurations. Use -D to
limit the checking. When -D is used the checking is limited to the given
configuration. Example: -DDEBUG=1 -D__cplusplus
-U<id>
By default Cppcheck checks all configurations. Use '-U'
to explicitly hide certain #ifdef <id> code paths from checking.
Example: '-UDEBUG'
--enable=<id>
Enable additional checks. The available ids are:
all
Enable all checks. It is recommended to only use
--enable=all when the whole program is scanned, because this enables
unusedFunction.
warning
Enable warning messages
style
Enable all coding style checks. All messages with the
severities 'style', 'performance' and 'portability' are enabled.
performance
Enable performance messages
portability
Enable portability messages
information
Enable information messages
unusedFunction
Check for unused functions. It is recommend to only
enable this when the whole program is scanned
missingInclude
Warn if there are missing includes. For detailed
information use --check-config
By default none of the additional checks are enabled. Several ids
can be given if you separate them with commas, e.g.
--enable=style,unusedFunction. See also --std
--error-exitcode=<n>
If errors are found, integer <n> is returned
instead of default 0. EXIT_FAILURE is returned if arguments are not valid or
if no input files are provided. Note that your operating system can modify
this value, e.g. 256 can become 0.
--errorlist
Print a list of all possible error messages in XML
format.
--exitcode-suppressions=<file>
Used when certain messages should be displayed but should
not cause a non-zero exitcode.
--file-list=<file>
Specify the files to check in a text file. One filename
per line. When file is -, the file list will be read from standard
input.
-f, --force
Force checking of files that have a lot of
configurations. Error is printed if such a file is found so there is no reason
to use this by default. If used together with --max-configs=, the last option
is the one that is effective.
-h, --help
Print help text.
-I <dir>
Give path to search for include files. Give several -I
parameters to give several paths. First given path is searched for contained
header files first. If paths are relative to source files, this is not
needed.
--includes-file=<file>
Specify directory paths to search for included header
files in a text file. Add one include path per line. First given path is
searched for contained header files first. If paths are relative to source
files, this is not needed.
--config-exclude=<dir>
Path (prefix) to be excluded from configuration checking.
Preprocessor configurations defined in headers (but not sources) matching the
prefix will not be considered for evaluation of configuration
alternatives.
--config-exclude-file=<file>
A file that contains a list of config-excludes.
--include=<file>
Force inclusion of a file before the checked file. Can be
used for example when checking the Linux kernel, where autoconf.h needs to be
included for every file compiled. Works the same way as the GCC -include
option.
-i <dir>
Give path to ignore. Give several -i parameters to ignore
several paths. Give directory name or filename with path as parameter.
Directory name is matched to all parts of the path.
--inconclusive
Allow that Cppcheck reports even though the analysis is
inconclusive. There are false positives with this option. Each result must be
carefully investigated before you know if it is good or bad.
--inline-suppr
Enable inline suppressions. Use them by placing comments
in the form: // cppcheck-suppress memleak before the line to suppress.
-j <jobs>
Start <jobs> threads to do the checking work.
-l <load>
Specifies that no new threads should be started if there
are other threads running and the load average is at least <load>
(ignored on non UNIX-like systems)
--language=<language>
Forces cppcheck to check all files as the given language.
Valid values are: c, c++
--library=<cfg>
Use library configuration.
--max-configs=<limit>
Maximum number of configurations to check in a file
before skipping it. Default is 12. If used together with --force, the last
option is the one that is effective.
--max-ctu-depths=<limit>
Maximum depth in whole program analysis. Default is
2.
--platform=<type>
Specifies platform specific types and sizes.The available
platforms are:
unix32
32 bit unix variant
unix64
64 bit unix variant
win32A
32 bit Windows ASCII character encoding
win32W
32 bit Windows UNICODE character encoding
win64
64 bit Windows
By default the platform which was used to compile Cppcheck is
used.
-q, --quiet
Only print something when there is an error.
-rp, -rp=<paths>, --relative-paths;,
--relative-paths=<paths>
Use relative paths in output. When given, <paths>
are used as base. You can separate multiple paths by ';'. Otherwise path where
source files are searched is used. E.g. if given value is test, when checking
test/test.cpp, the path in output will be test.cpp instead of test/test.cpp.
The feature uses string comparison to create relative paths, so using e.g. ~
for home folder does not work. It is currently only possible to apply the base
paths to files that are on a lower level in the directory tree.
--report-progress
Report progress when checking a file.
--rule=<rule>
Match regular expression to create your own checks. E.g.
rule "/ 0" can be used to check division by zero. This command is
only available if cppcheck was compiled with HAVE_RULES=yes.
--rule-file=<file>
Use given rule XML file. See
https://sourceforge.net/projects/cppcheck/files/Articles/ for more info about
the syntax. This command is only available if cppcheck was compiled with
HAVE_RULES=yes.
--std=<id>
Set standard. The available options are:
posix
POSIX compatible code
c89
C code is C89 compatible
c99
C code is C99 compatible
c11
C code is C11 compatible (default)
c++03
C++ code is C++03 compatible
c++11
C++ code is C++11 compatible (default)
Example to set more than one standards: 'cppcheck --std=c99
--std=posix file.cpp'
--suppress=<spec>
Suppress a specific warning. The format of <spec>
is: [error id]:[filename]:[line]. The [filename] and [line] are optional.
[error id] may be * to suppress all warnings (for a specified file or files).
[filename] may contain the wildcard characters * or ?.
--suppressions-list=<file>
Suppress warnings listed in the file. Each suppression is
in the format of <spec> above.
--suppress-xml=<.xml file>
Use suppressions defined in xml as described in the
manual
--template='<text>'
Format the error messages. E.g.
'{file}:{line},{severity},{id},{message}' or '{file}({line}):({severity})
{message}'. Pre-defined templates: gcc, vs
-v, --verbose
More detailed error reports
--version
Print out version information
--xml
Write results in XML to error stream
--xml-version=<version>
Select the XML file version. Currently versions 1 and 2
are available. The default version is 1.
