LCppC - Lean Cppcheck

License

About the name

This is a fork of the original Cppcheck project, that aims at providing a lean, fast and mature static code analysis tool for C and C++.

Manual

A manual (for mainline cppcheck) is available online. It should be mostly compatible with LCppC: https://cppcheck.sourceforge.net/manual.pdf

Compiling

Any modern C++ compiler should work. If your compiler has the C++11 features that are available in Visual Studio 2019 / Clang 8 / GCC 8 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
• Windows: Visual Studio
• Windows: Qt Creator + mingw
• Linux/BSD: GNU Make with g++ or clang++
• Linux/BSD: gcc++ or clang++ directly

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

Debug build:

make DEBUG=yes

The recommended release build is:

```shell
make MATCHCOMPILER=yes FILESDIR=/usr/share/cppcheck HAVE_RULES=yes CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function"

Flags:

1. MATCHCOMPILER=yes Python is used to optimise cppcheck. The Token::Match patterns are converted into C++ code at compile time.

2. FILESDIR=/usr/share/cppcheck Specify folder where cppcheck files are installed (addons, cfg, platform)

3. HAVE_RULES=yes Enable rules (PCRE is required if this is used)

4. DEBUG=yes Use debug configuration.

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

mingw32-make LDFLAGS=-lshlwapi

Other Compiler/IDE

1. Create an 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" RDYNAMIC=""
mv cppcheck cppcheck.exe
