Error on Qt 6 Building from source for Windows Based

@Lemat You should check C:/Qt/CMakeFiles/CMakeError.log to see what exactly went wrong.

Lemat

Let me show you CMakeError.log:

This looks strange. This should be the call to the compiler, but instead vcvars64.bat is called. Can you show your script you created as described in the link (qt6vars.cmd)?

C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.28.29333/bin/Hostx64/x64/cl.exe

I'm not very familiar with Windows build environment, but is that OK?
I mean, it looks like the 64 bit version of cl.exe is being used, but it's strange that the Visual Studio installation went to the x86 folder, as a 32 bit application?

Could you please describe your environment? i.e. Windows OS version and platform, same for Visual Studio.

Lemat

@jsulm
owww !!, that is the CXX variable i set in system environment. i should change it to vcvarsall.bat

Lemat

@Lemat
right ? you agree ?

Lemat

@Pablo-J-Rogina

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

@jsulm

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

jsulm

@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

SGaist

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
