PCRE is a library that is used by the optional "rules" feature for the command
|
|
line version of cppcheck. It is readily available on Linux and Mac OS X, but
|
|
must be obtained separately for Windows.
|
|
|
|
If you're using qmake to generate makefiles, the following behavior applies:
|
|
|
|
- If you're not on Windows, it assumes by default that you have PCRE and want
|
|
to enable rules support. You can disable rules support (removing the PCRE
|
|
dependency) by passing HAVE_RULES=no to qmake.
|
|
|
|
- If you are on Windows, but have PCRE available, you can enable rules support
|
|
by passing HAVE_RULES=yes to qmake.
|
|
|
|
- Note: This includes using build.bat since it calls qmake - to use PCRE and
|
|
build.bat, you need to run set HAVE_RULES=yes before each run of build.bat

Build instructions
|
|
------------------
|
|
|
|
Windows
|
|
-------
|
|
|
|
Visual Studio
|
|
|
|
To build PCRE, download the source code from www.pcre.org and
|
|
CMake (https://cmake.org/download/). We assume you use Visual Studio 2015 -
|
|
otherwise adapt the commands for your version.
|
|
|
|
VS Solution file
|
|
cmake . -G "Visual Studio 14 2015"
|
|
Open PCRE.sln with VS IDE or via cmd:
|
|
call "%VS140COMNTOOLS%..\..\VC\vcvarsall.bat" x86
|
|
MSBuild PCRE.sln /target:Build /property:Configuration="Release"
|
|
|
|
For 64-bit target: cmake . -G "Visual Studio 14 2015 Win64"
|
|
|
|
or using NMake
|
|
call "%VS140COMNTOOLS%..\..\VC\vcvarsall.bat" x86
|
|
cmake . -G "NMake Makefiles"
|
|
nmake
|
|
|
|
or using MSYS
|
|
cmake . -G "MSYS Makefiles"
|
|
make
|
|
|
|
|
|
Linux
|
|
-----
|
|
|
|
The normal Makefile should work.
|
|
|
|
Install PCRE on Ubuntu might be needed:
|
|
sudo apt-get install libpcre3 libpcre3-dev
|
|
|
|
|
|
Mac OSX
|
|
-------
|
|
|
|
Install PCRE:
|
|
|
|
homebre
|
|
brew install pcre
|
|
|
|
or macport
|
|
sudo port install pcre
|
|
|
|
Ensure /path/to/pcre.h is in CXXFLAGS, e.g:
|
|
|
|
for homebrew
|
|
export CXXFLAGS=${CXXFLAGS}:/usr/local/include
|
|
|
|
or macport
|
|
export CXXFLAGS=${CXXFLAGS}:/opt/local/include
|
|
|
|
Or for MSVC copy pcre.lib and pcre.h in /externals directory.
