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++.

Manual

A manual is available online.

Compiling

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 2013 / GCC 4.6 then it will work.

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++

qmake

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

cd gui
qmake
make

Visual Studio

Use the cppcheck.sln file. The file is configured for Visual Studio 2015, 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 /externals then.

Qt Creator + MinGW

The PCRE dll is needed to build the CLI. It can be downloaded here: http://software-download.name/pcre-library-windows/

GNU make

Simple, unoptimized build (no dependencies):

make

The recommended release build is:

make SRCDIR=build CFGDIR=cfg HAVE_RULES=yes CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function"

Flags:

  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)

  4. CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function" Enables most compiler optimizations, disables cppcheck-internal debugging code and enables basic compiler warnings.

g++ (for experts)

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

g++ -o cppcheck -std=c++11 -Iexternals/simplecpp -Iexternals/tinyxml -Ilib cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml/*.cpp

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

g++ -o cppcheck -std=c++11 -lpcre -DHAVE_RULES -Ilib -Iexternals/simplecpp -Iexternals/tinyxml cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml/*.cpp

MinGW

mingw32-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. Add all cpp files in the externals folders to the project file / makefile.
  4. 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
