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.
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.
