Compiling LyX 1.5 for Win32
===========================

LyX 1.5 can be compiled with Microsoft Visual C++ 2005 or MinGW.

Compiling with MSVC 2005
========================

1	Install MSVC 2005

	If you don't have MSVC 2005 installed, download and install the free
	Express edition from http://msdn.microsoft.com/vstudio/express/visualc/
	(Do not install the service pack 1 for MSVC 2005 as this introduces a bug
	 that makes compiling LyX's Qt 4 frontend impossible, see
	 http://support.microsoft.com/?scid=kb%3Ben-us%3B930198&x=13&y=12)

2	Install the Windows Platform SDK

	see: http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
	(You don't need to install the IIS, MDAC, and Tablet PC SDK that are
	 delivered with the Platform SDK.)

3	configure MSVC

	Follow exactly the steps of
	http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
	In Step 3 follow also the things noted as alternative.
	(If you later get an error message that "windows.h" cannot be found,
 	 create the global Windows environment variables "INCLUDE" and "LIB".
	 INCLUDE contains the paths to the "include" folders of the installed
	 platform SDK and of MSVC. LIB contains the corresponding "lib" folders.)

4	Install Python

	Get the latest Python 2.5 version at
	http://www.python.org/download/releases/2.5/

	Install in C:\Python25 and add this directory to the PATH environment
	variable (Start > Settings > Control Panel > System > Advanced >
	Environment Variables).

5	Install SCons

	Download and install SCons 0.96.92 (or newer, but not 0.96.1) from http://www.scons.org/download.php

6	Install the dependencies

	Download http://www.lyx.org/~bpeng/lyx-windows-deps-msvc-qt422.zip
	and extract in the root directory of your LyX files (so you will get
	a directory called lyx-windows-deps-msvc next to the other directories
	like src, development etc.).

7	Compile

	From MS Visual Studio command prompt (not the regular cmd.exe), 
	run development\Win32\packaging\build_msvc.bat

8	First start of LyX

	To start the just compiled lyx.exe, it is necessary to copy the following
	files to the folder where the just compiled "lyx.exe" is:

	Aiksaurus.dll
	aspell.dll
	iconv.dll
	intl.dll
	Microsoft.VC80.CRT.manifest
	msvcp80.dll
	msvcr80.dll
	QtCore4.dll
	QtGui4.dll

	All files except of the msvcp80.dll and msvcr80.dll should be present on your system.
	The missing files can be downloaded from:
	http://wiki.lyx.org/uploads/DevelTools/buildLyx/LyXWinBuildDLLs.zip
	(Currently there is a bug in the aspell.dll, so use the version that is delivered in this zip-file.)

	msvcp80.dll and msvcr80.dll are the C Runtime and C++ libraries
	supplied with MSVC 2005. They are freely redistributable.
	See http://msdn2.microsoft.com/en-us/library/8kche8ah(VS.80).aspx
	for details.

	All of the other .dlls above and the lyx executable are compiled
	from code released under the GPL which states (section 3) that
	GPL software may be linked against system files such as msvcp80.dll
	and msvcr80.dll.

Compiling with MinGW
====================

1	Install MinGW, and all the gcc-related stuff, and win32api. 

2	download qt-win-opensource-4.x.x-mingw.exe and install to c:\qt\4.2.2.

3	install python and scons as instructed above. Set $path for python
	   to make your life a bit easier.

4	Check out lyx svn to c:\lyx-devel\lyx-1.5.x

5	Download zlib binaries and developer files (zlib-1.2.3-bin.zip and
	   zlib-1.2.3-lib.zip) from http://gnuwin32.sourceforge.net/packages/zlib.htm
	   libiconv from http://gnuwin32.sourceforge.net/packages/libiconv.htm
	   gettext  from http://gnuwin32.sourceforge.net/packages/gettext.htm
	   unpack all of them to the same directory c:\lyx-devel\mingw_deps.

6	start a command window, run commands:
	   $ cd c:\lyx-devel\lyx-1.5.x
	   $ scons -f development\scons\SConstruct \
	       extra_lib_path=..\mingw_deps\lib  \
		   extra_inc_path=..\mingw_deps\include \
		   extra_bin_path=..\mingw_deps\bin \
		   qt_dir=c:\qt\4.2.2 \
		   DESTDIR=..\lyx-1.5-install \
		   install


Creating the Installer
======================

	To create an installer with LyX and all related components, download
	and install the latest NSIS from http://nsis.sourceforge.net

	Open development\Win32\packaging\installer\setttings.user.nsh and modify
	the settings depending on your build environment.

	Finally, go to development\Win32\packaging\installer
	(in a normal Windows Explorer), right-click on lyx.nsi and click
	"Compile NSIS Script".

	You can also use the installer target of scons. Namely, use a command like
	   $ scons -f development\scons\SConscript installer
	This will create $BUILDDIR\lyx-version-timestamp-Installer.exe for a devel version,
	and $BUILDDIR\lyx-version-Install.exe for a released version of lyx.

	If you also want to generate bundled installer, download 
	lyx-windows-bundle-deps.zip from http://www.lyx.org/~bpeng, unpack
	to lyx-windows-bundle-deps under the top source directory, and run
	  $ scons -f development\scons\SConstruct installer bundle=1
	If you prefer to use another directory, you can use option bundle_dir like
	  $ scons -f development\scons\SConstruct installer bundle=1 bundle_dir=c:\bundle
