This guide uses UPLOADR to indicate the root of the Flickr Uploadr
source tree on your filesystem.  It probably shouldn't contain spaces
(C:\Documents and Settings\you\My Documents\Flickr Uploadr is probably
a bad idea).

On Windows, you must use the MSys bash shell to build Uploadr.  Cygwin
is not supported.  Instructions for getting your MSys environment setup
are included below.

You can obtain the Flickr Uploadr source code from either a tarball or
from Subversion.

Download tarball:
  http://flickr.com/tools/uploadr/

Checkout from Subversion:
  $ svn co http://code.flickr.com/svn/trunk/uploadr UPLOADR


Windows Build Environment
------------------------------------------------------------------------

If you're planning on building the third party libraries on windows 
(graphics magick, exiv2, ffmepg) then you'll need to have MS Visual C++
version 8 or greater installed. Version 7 will work for the third party
libraries themselves, but version 8 is required for building the final
DLLs.

To build the installers and such, you'll need to install MSYS. Start 
by going here:

http://sf.net/project/showfiles.php?group_id=2435

Choose 'MSYS Base System', then find the file called something like
'msysCORE-1.0.11-2007.01.19-1.tar.bz2'. Unzip this (get WinRaR if you
can't open it) and put it at C:\msys

Download the following files from the 'MSYS Base System' page:

    MSYS-1.0.11-20071204.tar.bz2
    bash-3.1-MSYS-1.0.11-1.tar.bz2
    coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2

And download these file from the 'MSYS Supplementary Tools' page:

    perl-5.6.1-MSYS-1.0.11-1.tar.bz2
    crypt-1.1-1-MSYS-1.0.11-1.tar.bz2

Version numbers may be higher. Unzip them into the same folder as 
MSYS, overwriting any existing duplicate files.

When you launch MSYS via the batch file in its root folder, you should 
be able to type 'perl -v' and get a Perl banner if all went well.

Follow these steps to get MSYS working with Visual Studio:

http://arrozcru.no-ip.org/ffmpeg_wiki/tiki-index.php?page=Fixing+msys

From the same download page, download the following packages:

  From the MinGW Runtime section:
      mingw-runtime-3.14.tar.gz

  From the GNU Binutils section:
      binutils-2.18.50-20080109-2.tar.gz

  From the MinGW API for MS-Windows section:
      w32api-3.11.tar.gz

  From the GCC Version 4 / Technology Preview: gcc-4.2.1-sjlj-2 section:
      gcc-core-4.2.1-sjlj-2.tar.gz
      gcc-g++-4.2.1-sjlj-2.tar.gz

Unpack each package into C:\msys\mingw then go to C:\msys\mingw\bin\ and 
rename:

  c++-sjlj.exe to c++.exe
  cpp-sjlj.exe to cpp.exe
  g++-sjlj.exe to g++.exe
  gcc-sjlj.exe to gcc.exe

Follow these instructions to make mingw work with msys:

http://arrozcru.no-ip.org/ffmpeg_wiki/tiki-index.php?page=Integrating+MinGW+with+MSys

You probably already have an SVN client, but if not, you can grab the
commandline one from here:

  http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91
  svn-1.4.6-setup.exe (or a more recent version)

Once installed, typing 'svn --version' from a fresh MSYS shell should give 
you a version banner.

Next you'll need a zip utility. Grab this zip file:

  ftp://ftp.info-zip.org/pub/infozip/WIN32/zip232xN.zip

And copy zip.exe into msys/bin. Ok, all ready!


XULRunner
------------------------------------------------------------------------

XULRunner trunk builds:
  ftp://ftp.mozilla.org/pub/mozilla.org/xulrunner/nightly/latest-trunk/

Note: You want the version *without* 'sdk' in the name.


Download a version of XULRunner trunk and unzip it into:
  UPLOADR/MacUploadr.app/Contents/Resources/

The XULRunner files (e.g. xulrunner.exe) should now be here:
  UPLOADR/MacUploadr.app/Contents/Resources/xulrunner/

Make sure you unzip the file keeping directory paths intact. There should
be several folders inside the 'xulrunner' folder, including 'chrome',
'components', etc.


Gecko SDK
------------------------------------------------------------------------

To build the XPCOM components you will need the Gecko SDK:
  http://developer.mozilla.org/en/docs/Gecko_SDK#Downloading

Place the SDK here:
  UPLOADR/MacUploadr.app/Contents/Resources/gecko-sdk.win

These SDKs are from the Gecko 1.8 series and so are only safe to use
if the XPCOM components use only frozen interfaces.  Fortunately,
Uploadr currently falls into this category.


You'll also need bits from Mozilla's Wintools:
  http://ftp.mozilla.org/pub/mozilla.org/mozilla/source/wintools.zip

Extract that and copy glib-1.2.dll and libIDL-0.6.dll from
wintools/buildtools/windows/bin/x86/ to your gecko-sdk.win/bin/ directory.



API Keys
------------------------------------------------------------------------

You'll need your own API key and secret from Flickr to build Uploadr.
These can be obtained at http://flickr.com/services/api/.  The key
and secret must be placed in flKey.cpp in the spaces provided. Copy
flKey.cpp.template to flKey.cpp and insert your keys:

  UPLOADR/MacUploadr.app/Contents/Resources/components/flKey.cpp.template
  UPLOADR/MacUploadr.app/Contents/Resources/components/flKey.cpp

The API key is stored as a string.  The secret is stored as individual
characters so it is not easily readable from the binary.

There are blocks to keep both a Windows and Mac key/secret in the same
source file (you certainly don't have to, though).  This is mainly
important for the official builds.



GraphicsMagick
------------------------------------------------------------------------

Download GraphicsMagick Windows SOURCE:
  ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/windows/

You'll need MS Visual C++ to build GraphicsMagick. We've built it 
sucessfully using VC++ 7 and 8, but other versions may work fine.

Go to the VisualMagick/configure directory of the GraphicsMagick Windows
source directory.  Open configure.vcproj in Visual Studio and edit the 
project configuration:

  o Set the active configuration to "Release"
  o Change the Use of MFC under Configuration Properties > General to
    "Use MFC in a Static Library"
  o Change the Runtime Library under Configuration Properties > C/C++ >
    Code Generation to "Multi-threaded (/MT)"

Build the project and then run the configuration program (called 
configure.exe, in the same folder as the .vcproj file). Select "Static
Multi-threaded runtimes" and otherwise accept the defaults.  This will
create your solution (project file) for Visual Studio in the root
GraphicsMagick folder. It should be called 'VisualStaticMT.sln'.

Open the solution and let Visual Studio 8 have its way with the Visual
Studio 7 solution file.  Edit the project configuration:

  o Set the active configuration to "Release" for 'All'
  o Change the Runtime Library for the CORE_Magick++ project under
    Configuration Properties > C/C++ > Code Generation to
    "Multi-threaded DLL (/MD)"
  o Tell all of the CORE_* projects to optimize for speed under
    Configuration Properties > C/C++ > Optimization
    (Optimization: "Maximize Speed /O2")

Build it to see where the problems are.  As of 1.1.8, 18 out of 20
projects build properly.  The two that do not are utilities that are
extraneous.  In 1.1.7, the errors that will likely show up in a
try/catch block can be fixed by changing "exception" to "std::exception"
and adding "&" to make all of the catches happen by reference.  The
official builds are build with 1.1.10 and will soon move to 1.1.11.

You can verify that enough of it built correctly by checking in the 
VisualMagick\lib directory. There should be a .lib file for each 
CORE_* project.

Add the path to your GraphicsMagick build's VisualMagick\lib directory
to your library path.  Add the path to VisualMagick\include to your
include path.

The magic.mgk, modules.mgk and delegates.mgk files must be in the root of
the application (next to application.ini).  These files are included in
the tarball and Subversion checkouts, so you shouldn't have to worry. You
can otherwise find them in the VisualMagick\bin directory.


Exiv2
------------------------------------------------------------------------

Download Exiv2 source from:
  http://exiv2.org/download.html

Download and install Expat for Windows:
  http://sourceforge.net/project/showfiles.php?group_id=10127

Open up the solution file at 'msvc\exiv2.sln'. Just like GraphicsMagick, 
let Visual Studio 8 eat the 7.1 project files. Edit the project 
configuration:

  o Disable every project in the Exiv2 solution except exiv2lib and xmpsdk
    (Use the configuration manager and uncheck the boxes)
  o Change the Runtime Library for remaining projects under
    Configuration Properties > C/C++ > Code Generation to
    "Multi-threaded DLL (/MD)"
  o Set remaining projects to their Release state
  o Modify the xmpsdk project:
      o Change Configuration Properties > C/C++ > General >
        Additional Include Directories to (all one line):
        "..\..\..\expat-2.0.1\lib;..\..\xmpsdk\src;..\..\xmpsdk\include;"
        "C:\Program Files\Expat 2.0.1\Source\lib"
        (the last path portion might be different, depending on where
        you install expat).
      o Change Configuration Properties > Librarian > General >
        Additional Dependencies to "libexpat.lib"
      o Change Configuration Properties > Librarian > General >
        Additional Library Directories to:
        "$(SolutionDir)/lib";"C:\Program Files\Expat 2.0.1\Bin"
  o Modify the exiv2lib project:
      o Change Configuration Properties > Librarian > General >
        Link Library Dependencies to "Yes" (VC7 doesn't seem to have 
        this option - just skip it)
      o Change Configuration Properties > C/C++ > General >
        Additional Include Directories to:
        "..\..\src;..\..;..\..\xmpsdk\include"

You should now be able to build the solution. It should produce the
following files:

        msvc\exiv2lib\Release\exiv2.lib
        msvc\xmpsdk\Release\xmpsdk.lib

Copy libexpat.dll from "C:\Program Files\Expat 2.0.1\Bin" to
"UPLOADR\MacUploadr.app\Contents\Resources".


FFmpeg
------------------------------------------------------------------------

FFmpeg will not build in Visual Studio but can be linked by Visual
Studio, so we'll need to use MSys/WinGW.

--- I'm dubious that we need to install anything extra here [CAL]
--- But i need to wait until i actually get gm.dll linking
--- Additionally add in dependencies like zlib:
---   http://wiki.videolan.org/Win32CompileMSYS

Check out and build the most recent version of FFmpeg:
(handy hint: Shift+Insert pastes into the MSYS shell)

  $ svn co svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
  $ cd ffmpeg
  $ ./configure --disable-ffserver --disable-ffplay --enable-gpl \
    --enable-memalign-hack --enable-static --disable-shared \
    --disable-debug --enable-swscale

The lastest version of FFmpeg is kinda broken on windows and needs
to be built one library at a time,. This should do the trick:

  $ cd libswscale && make && cd ..
  $ cd libavdevice && make && cd ..
  $ cd libavformat && make && cd ..
  $ cd libavcodec && make && cd ..
  $ cd libavutil && make && cd ..
  $ make

make install on windows doesn't work for FFmpeg trunk at the moment.
that may or may not be a problem...

The Uploadr Visual Studio project is setup to expect the MinGW bits for
linking FFmpeg into the flGM XPCOM object.


Building XPCOM components
------------------------------------------------------------------------

If you make any changes to the IDL files defining the XPCOM interfaces,
you must increment the BuildID defined in:
  UPLOADR/MacUploadr.app/Contents/Resources/application.ini

Use the Visual Studio projects in:
  UPLOADR/MacUploadr.app/Contents/Resources/components/*.vcproj

The two projects will generate gm.dll and key.dll.


Running Flickr Uploadr
------------------------------------------------------------------------

Copy xulrunner-stub.exe from the xulrunner/ directory into the root
of your app, UPLOADR/MacUploadr.app/Contents/Resources/, rename it to
"Flickr Uploadr.exe" and double-click it to run Uploadr.

You can hack the icons.ico file into the executable using Resource
Hacker:
  http://angusj.com/resourcehacker/

Create a shortcut to this executable and append the "-console
-jsconsole" parameters to launch Uploadr with both debug windows open.


Packaging
------------------------------------------------------------------------

Windows installers are created using NSIS, specifically the Unicode
version available here:
  http://www.scratchpaper.com/

Building the NSIS package will likely fail if you do not have Visual
Studio 8 installed.  The installer references vcredist_x86.exe.  For
controlled experimentation it is OK to omit this installation step by
commenting line 110 in UPLOADR/windows_install_build.nsi.

One-command builds in MSys for all eight languages:
  $ make win all

Or to build a single language:
  $ make win build en-US

If you do not want to create update files (see README.updates):
  $ make win all-build
