Sources were built with Clang but with increased verbosity of error detection. A number of syntax and semantic warnings were encountered. Commit adds changes to correct these warnings. Some changes involve removing extra, and unncessary, semi-colons at EOL (e.g. at end of switch clause). Project astyle settings are not currently setup to detect if a file is to have an extra carriage return after the last line of data. Two files were altered to ensure an extra carriage return. An advisory to enhance code was encountered in triage code. Clang advisory on a for-loop interation value suggested that: `use reference type 'const QString &' to prevent copying` |

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 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 MATCHCOMPILER=yes CFGDIR=cfg 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. -
CFGDIR=cfgSpecify folder where .cfg files are found -
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=""
mv cppcheck cppcheck.exe
