Hi
Did u install perl ?
Before trying to make a self compiled Qt version , check out

http://doc.qt.io/qt-5/windows-requirements.html
http://doc.qt.io/qt-5/linux-requirements.html

Also, why you need your own version ?

Hi,

Where exactly do you get that error ?

As @mrjj asked, did you install all build dependencies ?

What version of Visual Studio are you using ?

@SGaist

Now I can compile it correctly, but I need to know what the parameters of Qt 5.9.2 version configure.exe are.

@TANG-JI-QIANG_CHINA_ said in compile Qt error:

but I need to know what the parameters of Qt 5.9.2 version configure.exe are

Then call it with -h parameter:

configure -h

I only compiled the QtCore and QTWidget modules, with the debugging information DLL to replace the corresponding files in the installation directory, but there was an error. Is it necessary to compile it all?

[jsulm]

@TANG-JI-QIANG_CHINA_ Please just insert the error text here.

@TANG-JI-QIANG_CHINA_ I don't see the actual error in this screen-shot...

@jsulm
There are two kinds of index classes in QGraphicsScene: QGraphicsSceneBspTreeIndex and QGraphicsSceneLinearIndex, but they have some shortcomings for us, and we can't reset the index method from the outside, so only change the index class code.

@jsulm
Is Qt 5.9.2 compiled under win7 or under win8?

[jsulm]

@TANG-JI-QIANG_CHINA_ That you need to ask Qt developers, but I guess Windows 7. Why? It should work on both without issues.

@jsulm
I have been able to compile QT correctly, thank you for your patience.

@TANG-JI-QIANG_CHINA_ so if your issue is solved please don't forget to mark your post as such. Thanks
