Fix inconsistent instruction vs. corresponding explanation (paths were differing).

Build Instructions for the QtWebKit build on Windows

Dependencies

First of all you need a version of Qt for Windows. If you are an Open Source developer then you can for example download the Open Source Edition of Qt for Windows from the Trolltech Website: http://trolltech.com/developer/downloads/qt/windows

The following external GNU tools are needed from the GnuWin32 Project:

  • Make
  • Bison
  • Gperf
  • Flex
  • LibIconv (needed for bison)

In addition you need Perl. ActiveState Perl works fine for example. You can download it from the ActivePerl Website.

Make sure the GnuWin32 packages are in your PATH as well as Perl. You also need to have %QTDIR% set and have %QTDIR%\bin in your PATH.

Please note that building inside Cygwin is currently not supported.

Building QtWebKit

  • Open for example a Qt Command Prompt from the Start Menu
  • Change into the WebKit source tree
  • Run perl WebKitTools\Scripts\build-webkit --qt
  • Wait :)
  • build-webkit is likely to abort with an error when compiling testkjs if you're compiling with MingW g++. This is safe to ignore for now.
  • Try to run WebKitBuild\Release\bin\QtLauncher.exe

Notes about building QtWebKit with the Qt/Windows OpenSource Edition

  • Make sure that you are using Qt >= 4.3.2. Otherwise you may run into build problems with the Moc at the very end of the build process.
  • If you haven't set up your PATH already to include the GnuWin32 packages then you may want to execute the following command: set PATH=C:\GnuWin32\bin;C:\Perl\bin;%PATH% Provided that the GnuWin32 packages are installed in C:\GnuWin32\bin and Perl in C:\Perl\bin.
  • If you get build errors in JavaScriptCore\bindings\NP_jsobject.cpp or similar then please make sure that the Microsoft Platform SDK is NOT in your %INCLUDE% path because it conflicts with your MingW headers.
  • If you get build errors after makefile generation ("Makefile:178: * Multiple target patterns. Stop.") then you're probably still using the Cygwin version of make. Try removing Cygwin from your %PATH% for the time being (it's not currently supported, as mentioned above).
  • I had troubles with m4 when the GnuWin32 packages were installed in C:\Program Files\GnuWin32 (something choked on the whitespace), it worked when installing them into C:\GnuWin32 instead.
  • When I try to build using Qt 4.4.3 on windows, the above procedure throws error. all the build (perl) scripts are using unix style dir-paths. Example buildQMakeProject perl method in webkitdirs.pm uses unix style dir-path and also reading pro file. I am amazing that the people could build Qt port of Webkit on Windows.

Please Let me know exact steps / modification required to build the Webkit in Qt command prompt.
