Installation and use of Cppcheck

First download the Linux version from here: http://sourceforge.net/projects/cppcheck/files/cppcheck/

then download the corresponding version, unzip, then install:

Compile:

g++-o cppcheck-ilib cli/*.cpp lib/*.cpp

Installation:

Make install

Cppcheck default installation will error as follows:

Cppcheck:unusedfunction check can ' t be used with '-j ' option. disabling unusedfunction check.
(information) Failed to load STD.CFG. Your Cppcheck installation is broken, please re-install. The Cppcheck binary was compiled without cfgdir set. Either the STD.CFG should is available in CFG or the Cfgdir should is configured.   

So instead of using their make, I directly compile with the g++ parameter: g++-o cppcheck-ilib cli/*.cpp lib/*.cpp

And then it's checked.

Cppcheck-j 3--enable=all src/

1. Enable to check the rules:
   1. Default:--enable=error
   2. --enable=all
   3. --enable=unusedfuntion Path
   4. --enable=style
2. Rule definition:
   1. Error: Errors that occurred
   2. Warning: Recommended information for preventing bug-defensive programming
   3. Style: Coding format problem (no functions used, extra code, etc.)
   4. Portablity: Portability warning. Compatibility issues may occur if this section is ported to another platform
   5. Performance: It is recommended to optimize the performance of this part of the code
   6. Information: Some interesting information that you can ignore without looking at.
3. Save results to file: redirect >
4. -j 3 uses 3 threads, if the code works too large, you can use 15-20, you play it by yourself, but still refer to Cpuinfo

If it's a version of Windows, use it like this:

1, will cppcheck Green version Cppcheck.rar decompression;

2, open cppcheckgui.exe;

3. Menu check->directory;

4, select the source code directory, confirm;

5, Cppcheck automatically began to walk the check;
