Error on Qt 6 Building from source for Windows Based
-
Do you want to compile with MinGW or MSVC?
If MinGW - why do you call MSVC batch files which set MSVC specific env vars?
If MSVC - why do you call g++? -
Still does not explain why you set MSVC env vars when trying to build with MinGW.

Tyying this batch inspired from this post. I thank Chris Kawa.
I thought it was to build with MSVC 2019.

#define WINVER 0x0A00
#define _WIN32_WINNT 0x0A00Do I have to modify CMakeLists.txt or is it possibe to pass these defines from batch ?
Thank you -
The error tells you what's wrong. Mingw sets
_WIN32_WINNTandWINVERtoo low. I think Windows XP is its default and Qt6 requires at least Windows 10, so add defines for the appropriate versions in the configure params. Here are the values: WINVER and _WIN32_WINNT. -
@NiVa99 said:
So I understood but don't know where can i add those defines'param for a build MSVC, in the bat or in cmakelists.txt or ninja config ?
Sorry, but I'm completely confused now which build you're talking about. You're constantly mixing msvc, mingw and now ninja and I can't understand which errors you're getting from which build.
Could you maybe focus on one and state clearly which is it?
And don't modify any Qt files. -
Building according to this note Building Qt 6 from sources
Requirements are CMake, Ninja, Perl, Python.Build Qt from Sources I search for is doing it with MSVC 2019, VS2022 (and later Ming).

@NiVa99 said in Error on Qt 6 Building from source for Windows Based:
C:\Strawberry\c\bin\c++.exe
Remove C:\Strawberry\c\bin from your PATH environment variable, and try a clean build again.
Background: CMake prefers clang/gcc over MSVC, even on Windows. So if you have anything called clang.exe, c++.exe ... in your PATH cmake will try to use that for compilation. Anyhow, the binaries in C:\Strawberry\c\bin are only for internal use of Strawberry - at least they're not enough to compile Qt.
If you want to use MSVC, call vcvars64.bat like @Christian-Ehrlicher suggested. If you want to use MinGW, prefer one of the MinGW toolchains that are supported by Qt: https://wiki.qt.io/MinGW

Thank you !
Following your advise, I comment llvm, clang, perl, g++ so thery are out of PATH env var ( and after some where verifications), then launch configure.bat as described by official doc step-4-build-the-qt-library from src path like that :
