Cppcheck
=========
About
The original name of this program is "C++check" but it was later changed to "cppcheck".
Manual
A manual is available online:
https://cppcheck.sourceforge.io/manual.pdf
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.
There are multiple compilation choices:
* 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
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/picojson -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/picojson -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.
The official rpms are built with these files:
