cppcheck是一个个检测源码的工具，对编译工具的一个补充，mark
Cppcheck - A tool for static C/C++ code analysis Syntax: cppcheck [OPTIONS] [files or paths] If a directory is given instead of a filename, *.cpp, *.cxx, *.cc, *.c++, *.c, *.tpp, and *.txx files are checked recursively from the given directory. Options: --append=<file> This allows you to provide information about functions by providing an implementation for them. --check-config Check cppcheck configuration. The normal code analysis is disabled by this flag. -D<ID> By default Cppcheck checks all configurations. Use -D to limit the checking to a particular 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 * 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 * missingInclude Warn if there are missing includes. For detailed information, use '--check-config'. Several ids can be given if you separate them with commas. See also --std --error-exitcode=<n> If errors are found, integer [n] is returned instead of the default '0'. '1' 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 the 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. Add one filename per line. When file is '-,' the file list will be read from standard input. -f, --force Force checking of all configurations in files. If used together with '--max-configs=', the last option is the one that is effective. -h, --help Print this help. -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. -i <dir or file> Give a source file or source file directory to exclude from the check. This applies only to source files so header files included by source files are not matched. 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 one or more comments, like: '// cppcheck-suppress warningId' on the lines before the warning to suppress. -j <jobs> Start [jobs] threads to do the checking simultaneously. --language=<language>, -x <language> Forces cppcheck to check all files as the given language. Valid values are: c, c++ --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. --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 -q, --quiet Only print error messages. -rp, --relative-paths -rp=<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. We use 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 messages while checking a file. --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) More than one --std can be used: 'cppcheck --std=c99 --std=posix file.c' --suppress=<spec> Suppress warnings that match <spec>. The format of <spec> is: [error id]:[filename]:[line] The [filename] and [line] are optional. If [error id] is a wildcard '*', all error ids match. --suppressions-list=<file> Suppress warnings listed in the file. Each suppression is in the same format as <spec> above. --template='<text>' Format the error messages. E.g. '{file}:{line},{severity},{id},{message}' or '{file}({line}):({severity}) {message}' Pre-defined templates: gcc, vs, edit. -v, --verbose Output more detailed error information. --version Print out version number. --xml Write results in xml format to error stream (stderr). --xml-version=<version> Select the XML file version. Currently versions 1 and 2 are available. The default version is 1. Example usage: # Recursively check the current folder. Print the progress on the screen and # write errors to a file: cppcheck . 2> err.txt # Recursively check ../myproject/ and don't print progress: cppcheck --quiet ../myproject/ # Check test.cpp, enable all checks: cppcheck --enable=all --inconclusive --std=posix test.cpp # Check f.cpp and search include files from inc1/ and inc2/: cppcheck -I inc1/ -I inc2/ f.cpp For more information: http://cppcheck.sf.net/manual.pdf cppcheck: error: could not find or open any of the paths given.
