I just downloaded Qt 4.7.4 an decided to give it a try. I already have installed QtCreator 2.3.0 and have a my own build of 4.7.3 already.
The build on 4.7.3 works as expected and building the helpers in QtCreator 2.3.0 was as smooth as it could be.
But after building Qt 4.7.4 exactly the same way I build 4.7.3, which as I said works perfectly, I got an error building the helpers that says " include file: '../../src/corelib/global/qconfig.h': No such file or directory", I looked in my Qt 4.7.4 build, that didn't break in any way when building, and it was actually missing! the building process didn't generate the qconfig.h file.
Does anyone know if there are any known issues in building 4.7.4? Here's my configure command, it's exactly the same one I used for building Qt 4.7.3 which works great and build the helpers with no problems whatsoever.
configure -platform win32-msvc2010 -debug-and-release -opensource -mp -plugin-sql-sqlite -qt-zlib -qt-gif -qt-libpng -qt-libmng -qt-libtiff -qt-libjpeg -plugin-manifests -qmake -phonon -multimedia -webkit -script -scripttools -declarative -declarative-debug -arch windows -qt-style-windows -qt-style-windowsxp -qt-style-windowsvista -qt-style-plastique -qt-style-cleanlooks -qt-style-motif -qt-style-cde -no-qt3support -openssl -I C:\OpenSSL-Win32\include -L C:\OpenSSL-Win32\lib\VC
I have an intel Core i5 laptop with 6GB of RAM, windows 7 x64 and MSVC2010 building with the x86 compilers, I don't use x64 with Qt yet as it gave me some build issues.
