Cppcheck

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 4.6

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.

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++ 4.6 (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:

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/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

=====

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
