About the name

The original name of this program was "C++check", but it was later changed to "Cppcheck".

Despite the name, Cppcheck is designed for both C and C++.


A manual is available online.


Any C++11 compiler should work. For compilers with partial C++11 support it may work. If your compiler has the C++11 features that are available in Visual Studio 2010 then it will work. If nullptr is not supported by your compiler then this can be emulated using the header lib/cxx11emu.h.

To build the GUI, you need Qt.

When building the command line tool, PCRE is optional. It is used if you build with rules.

There are multiple compilation choices:

  • qmake - cross platform build tool
  • cmake - cross platform build tool
  • Windows: Visual Studio (VS 2010 and above)
  • Windows: Qt Creator + mingw
  • gnu make
  • g++ 4.6 (or later)
  • clang++


You can use the gui/ file to build the GUI.

cd gui

Visual Studio

Use the cppcheck.sln file. The file is configured for Visual Studio 2013, but the platform toolset can be changed easily to older or newer versions. The solution contains platform targets for both x86 and x64.

To compile with rules, select "Release-PCRE" or "Debug-PCRE" configuration. pcre.lib (pcre64.lib for x64 builds) and pcre.h are expected to be in /extlibs then.

Qt Creator + MinGW

The PCRE dll is needed to build the CLI. It can be downloaded here:

GNU make

Simple build (no dependencies):


The recommended release build is:

make SRCDIR=build CFGDIR=cfg HAVE_RULES=yes


  1. SRCDIR=build
    Python is used to optimise cppcheck

  2. CFGDIR=cfg
    Specify folder where .cfg files are found

  3. HAVE_RULES=yes
    Enable rules (PCRE is required if this is used)

g++ (for experts)

If you just want to build Cppcheck without dependencies then you can use this command:

g++ -o cppcheck -std=c++0x -include lib/cxx11emu.h -Iexternals/tinyxml -Ilib cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp

If you want to use --rule and --rule-file then dependencies are needed:

g++ -o cppcheck -std=c++0x -include lib/cxx11emu.h -lpcre -DHAVE_RULES -Ilib -Iexternals/tinyxml cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp


make LDFLAGS=-lshlwapi

Other Compiler/IDE

  1. Create a empty project file / makefile.
  2. Add all cpp files in the cppcheck cli and lib folders to the project file / makefile.
  3. Compile.

Cross compiling Win32 (CLI) version of Cppcheck in Linux

sudo apt-get install mingw32
make CXX=i586-mingw32msvc-g++ LDFLAGS="-lshlwapi" RDYNAMIC=""
mv cppcheck cppcheck.exe
