 *******************************************************************************
 **     Building on Unix Platforms, Cygwin, and MinGW
 *******************************************************************************

 ==================
 Build Requirements
 ==================

 -- autoconf 2.56 or later
 -- automake 1.7 or later
 -- libtool 1.4 or later
    * If using MinGW, these can be obtained by installing the MSYS DTK

 -- NASM
    * 0.98, or 2.01 or later is required for a 32-bit build
    * NASM 2.00 or later is required for a 64-bit build
    * NASM 2.07 or later is required for a 64-bit build on OS X.  This can be
      obtained from MacPorts (http://www.macports.org/).

    The binary RPMs released by the NASM project do not work on older Linux
    systems, such as Red Hat Enterprise Linux 4.  On such systems, you can
    easily build and install NASM from a source RPM by downloading one of the
    SRPMs from

    http://www.nasm.us/pub/nasm/releasebuilds

    and executing the following as root:

      ARCH=`uname -m`
      rpmbuild --rebuild nasm-{version}.src.rpm
      rpm -Uvh /usr/src/redhat/RPMS/$ARCH/nasm-{version}.$ARCH.rpm

    NOTE: the NASM build will fail if texinfo is not installed.

 -- GCC v4.1 or later recommended for best performance

 ======================
 Building libjpeg-turbo
 ======================

 The following procedure will build libjpeg-turbo on Linux, FreeBSD, 32-bit
 OS X, and Solaris/x86 systems (on Solaris, this generates a 32-bit library.
 See below for 64-bit build instructions.)

   cd libjpeg-turbo
   autoreconf -fiv
   sh ./configure
   make

 NOTE: Running autoreconf is only necessary if building libjpeg-turbo from the
 SVN repository.

 This will generate the following files under .libs/

   libjpeg.a
       Static link library for libjpeg-turbo

   libjpeg.so.62.0.0 (Linux, Solaris)
   libjpeg.62.dylib (OS X)
   libjpeg-62.dll (MinGW)
   cygjpeg-62.dll (Cygwin)
       Shared library for libjpeg-turbo

   libjpeg.so (Linux, Solaris)
   libjpeg.dylib (OS X)
   libjpeg.dll.a (Cygwin, MinGW)
       Development stub for libjpeg-turbo shared library

   libturbojpeg.a
       Static link library for TurboJPEG/OSS

   libturbojpeg.so (Linux, Solaris)
   libturbojpeg.dylib (OS X)
       Shared library and development stub for TurboJPEG/OSS

   libturbojpeg.dll (MinGW)
   cygturbojpeg.dll (Cygwin)
       Shared library for TurboJPEG/OSS

   libturbojpeg.dll.a (Cygwin, MinGW)
       Development stub for TurboJPEG/OSS shared library

 ========================
 Installing libjpeg-turbo
 ========================

 If you intend to install these libraries and the associated header files, then
 replace 'make' in the instructions above with

   make install prefix={base dir} libdir={library directory}

 For example,

   make install prefix=/usr/local libdir=/usr/local/lib64

 will install the header files in /usr/local/include and the library files in
 /usr/local/lib64.  If 'prefix' and 'libdir' are not specified, then the default
 is to install the header files in /opt/libjpeg-turbo/include and the library
 files in /opt/libjpeg-turbo/lib.

 NOTE: You can specify a prefix of /usr and a libdir of, for instance,
 /usr/lib64 to overwrite the system's version of libjpeg.  If you do this,
 however, then be sure to BACK UP YOUR SYSTEM'S INSTALLATION OF LIBJPEG before
 overwriting it.  It is recommended that you instead install libjpeg-turbo into
 a non-system directory and manipulate the LD_LIBRARY_PATH or create sym links
 to force applications to use libjpeg-turbo instead of libjpeg.  See
 README-turbo.txt for more information.

 =============
 Build Recipes
 =============

 32-bit Library Build on 64-bit Linux
 ------------------------------------

 Add

   --host i686-pc-linux-gnu CFLAGS='-O3 -m32' CXXFLAGS='-O3 -m32' LDFLAGS=-m32

 to the configure command line.

 to the configure command line.  libjpeg-turbo will automatically be built with
 the maximum optimization level (-xO5) unless you override CFLAGS and CXXFLAGS.

 To build a 64-bit version of libjpeg-turbo using Sun Studio, add

   --host x86_64-pc-solaris CC=cc CXX=CC CFLAGS='-xO5 -m64' \
     CXXFLAGS='-xO5 -m64' LDFLAGS=-m64

 to the configure command line.


 *******************************************************************************
 **     Building on Windows (Visual C++)
 *******************************************************************************

 ==================
 Build Requirements
 ==================

 -- GNU Make v3.7 or later
    * Can be found in MSYS (http://www.mingw.org/download.shtml) or
      Cygwin (http://www.cygwin.com/)

 -- Windows SDK for Windows Server 2008 and .NET Framework 3.5 (or a later
    version)

    http://msdn.microsoft.com/en-us/windows/dd146047.aspx

    * The Windows SDK includes both 32-bit and 64-bit Visual C++ compilers and
      everything necessary to build libjpeg-turbo.  If you do not already have
      Visual C++ installed, then this is the recommended solution.  Also tested
      with Microsoft Visual C++ 2008 Express Edition (both are free downloads.)
    * Add the compiler and SDK binary directories (for instance,
      c:\Program Files\Microsoft Visual Studio 9.0\VC\BIN;
      c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE;
      c:\Program Files\Microsoft SDKs\Windows\v6.1\bin)
      to the system or user PATH environment variable prior to building
      libjpeg-turbo.
    * Add the compiler and SDK include directories (for instance,
      c:\Program Files\Microsoft Visual Studio 9.0\VC\INCLUDE;
      c:\Program Files\Microsoft SDKs\Windows\v6.1\include)
      to the system or user INCLUDE environment variable prior to building
      libjpeg-turbo.
    * Add the compiler library directory (for instance,
      c:\Program Files\Microsoft Visual Studio 9.0\VC\LIB;
      c:\Program Files\Microsoft SDKs\Windows\v6.1\lib)
      to the system or user LIB environment variable prior to building
      libjpeg-turbo.

 -- NASM (http://www.nasm.us/) 0.98 or later (NASM 2.05 or later is required for
    a 64-bit build)

 ======================
 Building libjpeg-turbo
 ======================

   cd libjpeg-turbo
   make -f win/Makefile

 This will generate the following files under libjpeg-turbo\windows\:

   jpeg-static.lib        Static link library for libjpeg-turbo
   jpeg62.dll             Shared library for libjpeg-turbo
   jpeg.lib               Development stub for libjpeg-turbo shared library
   turbojpeg-static.lib   Static link library for TurboJPEG/OSS
   turbojpeg.dll          Shared library for TurboJPEG/OSS
   turbojpeg.lib          Development stub for TurboJPEG/OSS shared library

 If a 64-bit Windows platform is detected, then the build system will attempt
 to build a 64-bit version of libjpeg-turbo.  You can override this by running

   make -f win/Makefile WIN64=no


 *******************************************************************************
 **     Creating Release Packages
 *******************************************************************************

 The following commands can be used to create various types of release packages:

 make rpm

   Create RedHat-style binary RPM package.  Requires RPM v4 or later.

 make srpm

   This runs 'make dist' to create a pristine source tarball, then creates a
   RedHat-style source RPM package from the tarball.  Requires RPM v4 or later.

 make deb

   Create Debian-style binary package.  Requires dpkg.

 make dmg

   Create Macintosh package/disk image.  This requires the PackageMaker
   application, which must be installed in /Developer/Applications/Utilities.

 make udmg

   On 64-bit OS X systems, this creates a version of the Macintosh package and
   disk image which contains universal i386/x86-64 binaries.  The 32-bit fork of
   these binaries is backward compatible with OS X 10.4 and later.  The 64-bit
   fork can be made backward compatible as well by using the instructions in
   the "Build Recipes" section.  OS X 10.4 compatibility SDK required.

 make nsi

   When using MinGW, this creates a Win32 installer for the GCC version of the
   libjpeg-turbo SDK.  This requires the Nullsoft Install System
   (http://nsis.sourceforge.net/.)  makensis.exe should be in your PATH.

 make -f win/Makefile nsi

   This creates a Win32 installer for the Visual C++ version of the
   libjpeg-turbo SDK.  This requires the Nullsoft Install System
   (http://nsis.sourceforge.net/.)  makensis.exe should be in your PATH.
