* Set correct type and size of string and char literals Use that string and char literal tokens store the prefix. This makes it possible to distinghuish between different type of string literals (i.e., utf8 encoded strings, utf16, wide strings, etc) which have different type. When the tokens holding the string and character values have the correct type, it is possible to improve Token::getStrSize() to give the correct result for all string types. Previously, it would return the number of characters in the string, i.e., it would give the wrong size unless the type of the string was char*. Since strings now can have different size (in number of bytes) and length (in number of elements), add a new helper function that returns the number of characters. Checkers have been updated to use the correct functions. Having the size makes it possible to find more problems with prefixed strings, and to reduce false positives, for example in the buffer overflow checker. Also, improve the stringLiteralWrite error message to also print the prefix of the string (if there is one). * Add comment and update string length |

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
