Error on Qt 6 Building from source for Windows Based

Christian Ehrlicher

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++?

NiVa99

First want to call msvc VS2019 building arch amd64 x64 (done) and x86.
Second doing same build with mingw last as documented. link text

Christian Ehrlicher

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.

SET VS_ENVIRONMENT="c:\Program Files (x86)\Microsoft Visual Studio\2019\VC\Auxiliary\Build\vcvars64.bat"
SET SRC_DIR="d:\Logiciels\Qt\6.2.2\Src"
SET BUILD_DIR="d:\Logiciels\Qt\6.2.2\Build"
SET INSTALL_DIR="d:\Logiciels\Qt\6.2.2\vs2019-x64"
SET CONFIGURE_OPTIONS=-debug-and-release -mp -opensource -confirm-license

call %VS_ENVIRONMENT%
mkdir %BUILD_DIR%
mkdir %INSTALL_DIR%
cd %BUILD_DIR%
call %SRC_DIR%\configure -prefix %INSTALL_DIR% %CONFIGURE_OPTIONS%
cmake --build . --parallel
cmake --install .
cmake --install . --config Release
cd %INSTALL_DIR%
:: rmdir %BUILD_DIR% /Q /S
pause

I got these error, have to set WINVER and _WIN32_WINNT defines but how doing it ?

Performing C++ SOURCE FILE Test HAVE_WIN10_WIN32_WINNT failed with the following output:

microsoft modifying-winver-and-win32-winnt
#define WINVER 0x0A00
#define _WIN32_WINNT 0x0A00

Do I have to modify CMakeLists.txt or is it possibe to pass these defines from batch ?
Thank you

@Chris-Kawa

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 ?

post

Thank you.

NiVa99

It seems that it is well defined in qtbase\mkspecs\features\qt_module.prf|349| DEFINES *= _WIN32_WINNT=0x0A00

Why only in this file ?

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 :
