See README for further details about Quackle, its licensing, and its
copyright.

Quackle was first ported to Windows by John Fultz, jfultz@wolfram.com, who
is also the original author of this ReadMe.

I maintain the Windows version so that it can be built with either
Visual C++ or the GNU-based MinGW compiler.  As of Quackle 0.97,
I use the mingw tools bundled with Qt 4.7.4 to build the release version.
The build ought to work with Visual C++ Express, as well, but I'm not
sure whether Microsoft disables useful optimizations in that version,
so I won't guarantee that you'll get nice and fast optimized binaries.

All build commands are run from Windows' regular command shell.  The
tools are:

Free Tools Build:
------------------------------------
MinGW
Qt 4.8
git
cygwin (optional) - if you want to debug, you'll need gdb from cygwin.

Microsoft Tools Build:
------------------------------------
Visual C++
Qt 4.8
git

Installer build:
------------------------------------
Inno Setup 5


Also, you'll need to make sure the following things are set appropriately
in your environment...

* INCLUDE needs to include Qt's include\ directory
* LIB needs to include Qt's lib\ directory
* PATH needs to include MinGW's bin\ directory and Qt's bin/ directory.
* cygwin's bin directory (if present) should be on PATH, and it must
  be after MinGW.


Building is very straightforward.  The following steps will get you to a
working executable...

* Make sure your PATH includes Qt's 'bin' directory.  If you're building
  with MinGW, make sure your PATH includes MinGW's 'bin' directory, and
  that it's earlier than Qt's 'bin' directory on the PATH (otherwise,
  attempts to run it from the build layout may fail with DLL errors).

* In the directories quackle\, quackle\quackleio, and quackle\quacker,
  do the following...
  	qmake

    Free tools:                    Microsoft tools:
  	mingw32-make <target>          nmake <target>
 <target> can be debug, release, or empty if you want to build both.

* You can now run quackle\quacker\release\Quackle.exe

* If, when running Visual Studio builds, you get a "fatal error CVT1100",
  then it can be fixed as follows:
  + In the Solution Explorer, open up Quackle, then Generated Files
  + Look for any copies of quacker.res
  + Right-click on each one and choose Exclude From Project 

* Recent versions of Visual Studio no longer build XP-compatible binaries
  by default.  To change this in the project file, bring up the
  Quackle Properties page, and under the General configuration,
  change the "Platform Toolset" to one which indicates Windows XP
  compatibility.  Do this for the Quackle, quackleio, and libquackle
  projects (the minimum projects which are part of a standard Quackle install).


Additional things to know:
--------------------------
* To build the Quackle installer,
  + Copy QtCore4.dll and QtGui4.dll from Qt's bin/ directory into quackle\
  + If you're building with MinGW, copy mingwm10.dll, libstdc++-6.dll, and
    libgcc_s_dw2-1.dll from MinGW's bin/ directory into quackle\
  + From the Quackle directory, run the following...
    <full path to Inno Setup's ISCC.exe> installer.iss /FQuackleInstaller /O. /Q
  + Find the file QuackleInstaller.exe in the quackle\ directory.

* MinGW doesn't seem to come with a debugger, but the cygwin gdb
  seems to work great on MinGW-generated binaries.  Watch for
  conflicts between MinGW and cygwin if both are on the path at
  once, though.

* If you're more comfortable with project files you can run
    qmake -tp vc
  to generate project files.  I've included a 'quackle.sln' which contains
  all of the projects including all of the various utilities.  If you're
  not interested in the additional utilities, you can simply ignore
  Visual C++'s warnings about missing project files.  Only the quackle,
  quackleio, and quacker projects are absolutely necessary, and if you
  run qmake -tp vc in the directories mentioned above, you'll have those
  project files.


Building Qt libraries
---------------------
  You can download the mingw or Visual Studio versions of the prebuilt
  Qt libraries.
  
  To build your own libraries, download
    qt-win-opensource-src-<ver>.zip
  from Trolltech or a mirror.  Unpack it someplace.  Set your
  PATH so that it contains Qt's bin directory.  It should also
  include MinGW's bin directory if you're building for MinGW, or
  the results of having run VSVARS32.BAT (found in Common7\Tools)
  if you're building on Visual Studio.

  If you have cygwin installed, make sure that you do *not* have
  it on your PATH.  Then run
  
    configure -debug-and-release

  and follow the directions given at the end of the [moderately lengthy]
  configure process.

  Here's a helpful document on the process:
