For c++14, shifting a variable with a value larger than or equal to the number of bits in the variable is undefined. Left-shifting with a value equal to the number of bits of the variable is implementation defined. See also trac ticket #9306. |

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 2013 and above)
- Windows: Qt Creator + mingw
- gnu make
- g++ 4.6 (or later)
- clang++
cmake
Example, compiling Cppcheck with cmake:
mkdir build
cd build
cmake ..
cmake --build .
If you want to compile the GUI you can use the flag -DBUILD_GUI=ON
For rules support (requires pcre) use the flag -DHAVE_RULES=ON
For release builds it is recommended that you use: -DUSE_MATCHCOMPILER=ON
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 2019, 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. A current version of PCRE for Visual Studio can be obtained using vcpkg.
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 MATCHCOMPILER=yes FILESDIR=/usr/share/cppcheck HAVE_RULES=yes CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function"
Flags:
-
MATCHCOMPILER=yesPython is used to optimise cppcheck. The Token::Match patterns are converted into C++ code at compile time. -
FILESDIR=/usr/share/cppcheckSpecify folder where cppcheck files are installed (addons, cfg, platform) -
HAVE_RULES=yesEnable rules (PCRE is required if this is used) -
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 -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 -Iexternals/simplecpp -Iexternals/tinyxml cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml/*.cpp
MinGW
mingw32-make LDFLAGS=-lshlwapi
Other Compiler/IDE
- Create an empty project file / makefile.
- Add all cpp files in the cppcheck cli and lib folders to the project file / makefile.
- Add all cpp files in the externals folders to the project file / makefile.
- Compile.
Cross compiling Win32 (CLI) version of Cppcheck in Linux
sudo apt-get install mingw32
make CXX=i586-mingw32msvc-g++ LDFLAGS="-lshlwapi" RDYNAMIC=""
