About
|
|
|
|
The original name of this program is "C++check" but it was later changed to "cppcheck".
|
|
|
|
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 4.8
|
|
then it will work.
|
|
|
|
To build the GUI, you need Qt.
|
|
|
|
While building the command line tool, PCRE is optional. It is used if you build with rules.
|
|
|
|
For "bug hunting" you need Z3. Installing Z3:
|
|
* debian: "sudo apt-get install libz3-dev
|
|
* windows:
|
|
32-bit: https://github.com/Z3Prover/z3/releases/download/z3-4.8.7/z3-4.8.7-x86-win.zip
|
|
64-bit: https://github.com/Z3Prover/z3/releases/download/z3-4.8.7/z3-4.8.7-x64-win.zip
|
|
If you do not want to install z3 in some "system" include/lib paths you can put the files in
|
|
cppcheck/externals/z3/include and cppcheck/externals/z3/bin
|
|
|
|
There are multiple compilation choices:
|
|
* qmake - cross platform build tool
|
|
* cmake - cross platform build tool
|
|
* Windows: Visual Studio
|
|
* Windows: Qt Creator + mingw
|
|
* gnu make
|
|
* g++ 4.8 (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:
|
|
https://github.com/microsoft/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 build (no dependencies):
|
|
make
|
|
|
|
The recommended release build is:
|
|
make MATCHCOMPILER=yes FILESDIR=/usr/share/cppcheck HAVE_RULES=yes
|
|
|
|
Flags:
|
|
MATCHCOMPILER=yes : Python is used to optimise cppcheck at compile time
|
|
FILESDIR=/usr/share/cppcheck : Specify folder where cppcheck files are installed
|
|
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++11 -Iexternals -Iexternals/simplecpp -Iexternals/tinyxml2 -Ilib cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml2/*.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/tinyxml2 cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml2/*.cpp
|
|
|
|
mingw
|
|
=====
|
|
The "LDFLAGS=-lshlwapi" is needed when building with mingw
|
|
mingw32-make LDFLAGS=-lshlwapi
|
|
|
|
other compilers/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"
|
|
mv cppcheck cppcheck.exe
|
|
|
|
Packages
|
|
|
|
You can install Cppcheck with yum/apt/brew/etc.
