If the match compiler uses the 'verify' mode and we compile with -O2, some tests comparing the on-the-fly-parser to the compiled match fail. Small functions are inlined by the -O2 compile flag. If we disable function inlining and still compile with -O2, everything is back to normal. gdb didn't show anything useful during the mismatch since the needed variables are optimized out. Once we start printing them, the problem vanishes, too. -> Can only be diagnosed at the x86 assembly level. The problem vanished by switching the invocation order of Token::Match() and the compiled match, so just swap them. Also add commented out helper code to better diagnose mismatch problems.

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++ compiler should work.
To build the GUI, you need Qt.
When building the command line tool, PCRE is normally used. PCRE is optional.
There are multiple compilation choices:
- qmake - cross platform build tool
- Windows: Visual Studio or Qt Creator or MinGW
- gnu make
- g++
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 rules are normally enabled.
To compile with rules (PCRE dependency):
- the PCRE dll is needed. It can be downloaded from here.
To compile without rules (no dependencies):
- remove the preprocessor define
HAVE_RULESfrom the project - remove the pcre.lib from the project
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
To build Cppcheck with rules (PCRE dependency):
make HAVE_RULES=yes
To build Cppcheck without rules (no dependencies):
make
g++ (for experts)
If you just want to build Cppcheck without dependencies then you can use this command:
g++ -o cppcheck -Ilib cli/*.cpp lib/*.cpp
If you want to use --rule and --rule-file then dependencies are needed:
g++ -o cppcheck -lpcre -DHAVE_RULES -Ilib -Iexternals cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp
MinGW
make LDFLAGS=-lshlwapi
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
