It should be created when you will build qt libraries.

You mean when doing configure + nmake? I’m on Windows, by the way, my first post was scarce.
When I execute this line:

configure -platform win32-msvc2008 -debug-and-release

It fails with this message:

C:\Qt\4.8\src\corelib\global\qglobal.h(62) : fatal error C1083: Cannot open include file: ‘QtCore/qconfig.h’: No such file or directory

Actually, now that I take a closer look, it seems it’s failing when building qmake.

Make sure you have perl installed. The syncqt tool that configure uses to prepare the forwarding includes is a perl script.

That was it, thanks a lot!

Is that something new? I was able to compile 4.7.3 without problems.

Stable, official releases don’t require the syncqt tool to build the include/ directory. Building from git does require it.

That makes sense. Thanks!

Official releases have already have syncqt executed by the release team prior to zipping/tarballing. If building form git the onus is on the developer to do it.
