Error on Qt 6 Building from source for Windows Based

Lemat

Windows 10 Professional 20H2 19042.685 X64

Microsoft Visual Studio Community 2019
Version 16.8.4

i use this same MSVC version to build my Qt x64 apps.

Lemat

or what is the right compiler path ? this one ?: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\bin\Hostx64\x64

@Lemat I think that path is correct. Visual Studio itself is a x86 application, but it has compiler which generates x86_64 binaries.

Lemat

@jsulm all right

Lemat

should i set a real compiler path in the system environment variable CXX ?? i don't know the real compiler file name. my actual Qt 5.15.2 has detected it automatically. i am looking in her settings to find the compiler file name, but nothing.

jsulm

@Lemat I don't think so. It should work as described on that web page. I don't know why it doesn't work for you.

Lemat

i really need help for that. i tried anything, but nothing. Maybe cmake version ?

Lemat

Tools used:
Cmake version: 3.18.4 x64
Python: 3.7.3 x64
ActivePerl: 5.28 x64
Ninja: 1.10.2

Hi,

IIRC, cmake 3.19.2 or newer is recommended but I don't have the source at hand.

Lemat

@SGaist

Can you explain more ?

SGaist

You should update your cmake version.

Lemat

@SGaist

Okay. let me try. i am downloading cmake 3.19.3

Lemat

i tried with cmake 3.19.3, problem still exist

SGaist

Did you restart from a clean state ?

Lemat

@SGaist yes. i did it. but the problem still exist

SGaist

What did you do to ensure a clean state ?

Lemat

I Installed Qt 6.0.1 with the online Installer. Too bad for me. Many features such as QWebEngine are removed

@Lemat That and other modules will be added in the new versions during the year, read https://www.qt.io/blog/add-on-support-in-qt-6.0-and-beyond. So you have 2 options: 1) wait or 2) manually compile the modules

Lemat

@eyllanesc ,that is okay !. i just leaned on doc.qt.io. Waiting is the best option for me after failing on this subject title. laugh.

Use 5.15 and you're fine. Don't know why everyone needs to use Qt6 when it's documented that it's not feature complete... Qt6 does not have any advantage for an average user at the current state.
