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.
