Win32 build instructions
-------------------------

Tested using MS Visual Studio 2005 (VC8)

NOTE: If using a later version of any library, you need to modify Makefile.PL.

Be sure to run C:\Program Files\Microsoft Visual Studio 8\vc\vcvarsall.bat

1. Build libjpeg-turbo

Requires cygwin installed with GNU make.

* Download libjpeg-turbo-1.0.0.tar.gz
  NOTE: The vc.exe version only contains a DLL not a static library.
* Extract to ../libjpeg-turbo-1.0.0
* Download and install nasm.  Copy nasm.exe to the libjpeg-turbo-1.0.0 dir.
* Run: make -f win/Makefile
* Static library will be in windows/jpeg-static.lib

2. Build zlib (with x86 ASM)

* Download zlib125.zip, extract to ../zlib (needed for libpng to find it)
* Run: nmake /f win32/Makefile.msc LOC="-DASMV -DASMINF" OBJA="inffas32.obj match686.obj"

3. Build libpng

* Download png143.zip, extract to ../lpng143
* Run: nmake /f scripts/makefile.vcwin32 test

4. Build giflib, this one is a pain...

* Download giflib-4.1.6.tar.gz, extract to ../giflib-4.1.6
* Download http://www.azillionmonkeys.com/qed/pstdint.h as C:\Program Files\Microsoft Visual Studio 8\vc\include\stdint.h
* The old VC project files won't work, to get one that does:
  * Get the vs2008-1.66.zip file from Leptonica, http://code.google.com/p/leptonica/downloads/list
  * Extract vs2008/giflib4.1.6.zip and copy giflib.vcproj to giflib-4.1.6/windows
  * Edit giflib.vcproj and change Version from 9.00 to 8.00
  * Search/replace "..\..\lib\" to "..\lib\"
  * Open giflib.vcproj in Visual Studio.
  * Change to Release and build.

5. Build Image::Scale

perl Makefile.PL
nmake
nmake test
