how to build Qt5 with qtwebkit on Windows with MSVC 2008 - leveldb can't find stdint.h

Question

On a Windows 7 x64 box:

• I installed Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1
• I downloaded and unzipped Qt5.4.0 source from the "Source packages and Other releases" section of http://www.qt.io/download-open-source/#
• I built ICU 54.1 from source and installed it, per http://qt-project.org/wiki/Compiling-ICU-with-MSVC.
• I created a command prompt shortcut per http://doc.qt.io/qt-5/windows-building.html.
• I added stuff to the command prompt per http://qt-project.org/wiki/Building_Qt_5_from_Git and the Usage section of http://qt-project.org/wiki/Compiling-ICU-with-MSVC.

So my qt5vars.cmd is:

CALL "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat"
SET _ROOT=C:\qt\qt540
SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;C:\Python27;C:\Python27\Scripts;%PATH%
REM Uncomment the below line when using a git checkout of the source repository
REM SET PATH=%_ROOT%\qtrepotools\bin;%PATH%
SET QMAKESPEC=win32-msvc2008
SET PATH=%PATH%;C:\icu\dist\lib;C:\Ruby193\bin
SET INCLUDE=%INCLUDE%;C:\icu\dist\include
SET LIB=%LIB%;C:\icu\dist\lib
SET _ROOT=

• I updated qtwinextras\src\winextras\winshobjidl_p.h per Compiling Qt 5.3.2 + VS2008 + SDK7.1 error SHARDAPPIDINFOLINK.
• Per https://groups.google.com/forum/#!topic/theano-users/JReP5_Ligu4 and C99 stdint.h header and MS Visual Studio, I copied stdint.h from C:\Program Files\Microsoft Visual Studio 10.0\VC\include on another machine, and pasted it into C:\Qt\qt540\qtwebkit\Source\WTF\wtf. I commented out the declaration of WCHAR_MIN, and copied that modified stdint.h to c:\qt\qt540\qtwebkit\source\javascriptcore\runtime.

With that setup, from the qt5vars.cmd prompt above, I configured Qt with:

configure -prefix %CD%\qtbase -developer-build -opensource -opengl desktop -nomake tests -no-compile-examples -skip qtwebkit-examples -icu -plugin-sql-sqlite -platform win32-msvc2008 -confirm-license

Then ran nmake. I get a bunch of errors that leveldb can't find stdint.h:

There is a stdint.h in C:\Qt\qt540\qtwebkit\Source\ThirdParty\leveldb\port\win, but copying that file or my modified stdint.h to leveldb\db and leveldb\include\leveldb makes no difference - I get the same errors when building Qt.

What do I need to do to build qtwebkit with Qt, or at least get past this leveldb sdtint.h issue?

Answer 1

OK, I'm a dummy. Just needed to copy stdint.h to C:\Program Files\Microsoft Visual Studio 9.0\VC\include instead of to the path of every file that complains. Additionally, I commented out the declaration of WCHAR_MIN in stdint.h to avoid tons of warnings about redeclaring it.

Then using the configure statement in the original question, Qt5.4.0 built successfully, including qtwebkit! Took 11 hours to build, but it worked!
