Error on Qt 6 Building from source for Windows Based

Christian Ehrlicher · 7 Mar 2021, 15:10

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.

Chris Kawa · 7 Mar 2021, 15:17

This is the do_it.bat I'm using to build Qt6. Adjust the paths and configure options at the top to whatever you like. You only need to have CMake in PATH, nothing else, or you can just spell out its path right in the bat script.

SET VS_ENVIRONMENT="C:\Program Files (x86)\Microsoft Visual Studio 2019\VC\Auxiliary\Build\vcvars64.bat"
SET SRC_DIR="C:\Qt\6.0.1\Src"
SET BUILD_DIR="C:\Qt\6.0.1\Build"
SET INSTALL_DIR="C:\Qt\6.0.1\msvc2019_64"
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 Debug
cd %INSTALL_DIR%
rmdir %BUILD_DIR% /Q /S
pause

This builds Qt out of source (the only sane way to do it cleanly), copies result to the install directory and removes the temporary build directory (which can get huuuge if you're building everything).

Some notes on the discussion points above:

Depending on your version of VS (Pro, Cmmunity etc.) the VS install dir will look a bit different. If in doubt just find "x64 Native Tools Command Prompt for VS 2019" shortcut in your start menu and see where it points to
There are couple of different .bats to set VS environment. For x64 build use either vcvarsall.bat amd64 or a shortcut vcvars64.bat
Keep source and build directories next to each other e.g. <some path>\src and <some path>\build. Theoretically it should be possible to build out of source to anywhere, but I've had multiple problems with mismatched number of .. and the likes in the past so keep it this way just to make it easier for yourself.
It's a good idea to exclude whichever modules you don't need in configure options e.g. -skip qtdatavis3d. I usually use only about 3-5 modules and exclude everything else, which cuts down compilation time and output size immensely.

Hi,

Trying do_it.bat with VS2019 and Qt source 6.2.2 for x64 binaries (or following Qt Buidling from source) directives,
I got these errors:

Can you help me ?

Thank you

Either set CMAKE_PREFIX_PATH or LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
You will also need to set the FEATURE_clang CMake variable to ON to re-evaluate this check.
WARNING: Clang-based lupdate parser will not be available. LLVM and Clang C++ libraries have not been found.

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'ninja install'
Qt will be installed into 'C:/Qt/6.2.2/msvc2019_64'

To configure and build other Qt modules, you can use the following convenience script:

@NiVa99 The bat is explicitly for msvc. Your errors seem to come from using clang without environment set up for it. The path has msvc2019_64 in it and your build errors are from gcc/mingw.

You seem to have completely mixed up environment for those three different compilers. Which one do you actually want to use - msvc, clang or gcc/mingw ?

Notice that directory C:/Qt/6.2.2/Build disappear at this moment building.

Well yeah, because it's a temporary build directory and the bat removes it after the install: rmdir %BUILD_DIR% /Q /S. If you want it to stay just modify the bat and remove or comment out that line.

For mingw don't call the msvc bat to setup environment. I don't know if mingw has a handy bat to set it up for you, but if not then just do it manually by adding the relevant paths to bin, include and lib directories. Something like this

SET PATH=%PATH%;C:\mingw\bin
SET CPLUS_INCLUDE_PATH=C:\mingw\include
SET LIBRARY_PATH=C:\mingw\lib

substituting the paths to your actual mingw installation directories.

Thank you, I have removed rmdir line and I will try mingw build.

Just staying on msvc build, I have just one architecture x86 that does not build either than amd64 dll seeing it with Dependencies.

Don't put x86 in the quotes because it treats vcvarsall.bat x86 as a file name with space. Put the parameter outside of the quotes. It's the same for all architectures. You can also just use vcvars32.bat without any parameters, which does the same.

The error tells you what's wrong. Mingw sets _WIN32_WINNT and WINVER too 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.

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++?
