cppcheck/build-pcre.txt

PCRE is a library that is used by the optional "rules" feature. (It adds
some additional features to the command line client.) It's 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.

- If you're not on Windows, 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


Some temporary build instructions. This is work in progress.


Windows

Visual Studio

To build PCRE, download the source code from www.pcre.org and
CMake (http://www.cmake.org/cmake/resources/software.html).
Then I assume you use MSVC 2010 otherwise adapt the commands for your version.

VS Solution file
  cmake . -G "Visual Studio 10"
  Open PCRE.sln with VS IDE or via cmd:
    call "%VS100COMNTOOLS%..\..\VC\vcvarsall.bat" x86
    MSBuild PCRE.sln /target:Build /property:Configuration="Release"

  For 64-bit run: cmake . -G "Visual Studio 10 Win64"

or using NMake
  call "%VS100COMNTOOLS%..\..\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:

  sudo port install pcre

Ensure /path/to/pcre.h is in CXXFLAGS, e.g:

  export CXXFLAGS=${CXXFLAGS}:/opt/local/include

Or for MSVC copy pcre.lib and pcre.h in /externals directory.
