Error Building Qt6.3.0 from source for Windows

Gio26

Hello,
I'm trying to compile qt 6.3.0 with windows 11, visual studio 2022 comunity. I can't get over the error:
Error opening D: /raspi-qt-compile/raspi-qt6.3/qt-everywhere-src-6.3.0/qt-build-msvc2022_64/qtdeclarative/src/quickcontrols2/basic/impl/qtquickcontrols2basicstyleimplplugin_autogen_autogen/include_Rugtimplugin_autogen/include_Rugt .json for reading

The compile step is:

FAILED: qtdeclarative/src/quickcontrols2/basic/impl/meta_types/qt6qtquickcontrols2basicstyleimplplugin_metatypes.json.gen qtdeclarative/src/quickcontrols2/basic/impl/meta_types/qt6qtquickcontrols2basicstyleimplplugin_metatypes.json D:/raspi-qt-compile/raspi-qt6.3/qt-everywhere-src-6.3.0/qt-build-msvc2022_64/qtdeclarative/src/quickcontrols2/basic/impl/meta_types/qt6qtquickcontrols2basicstyleimplplugin_metatypes.json.gen D:/raspi-qt-compile/raspi-qt6.3/qt-everywhere-src-6.3.0/qt-build-msvc2022_64/qtdeclarative/src/quickcontrols2/basic/impl/meta_types/qt6qtquickcontrols2basicstyleimplplugin_metatypes.json

That's a very long path. I suspect you are hitting the Windows path length limit.

You can try to:

Disable the limit (https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd#enable-long-paths-in-windows-10-version-1607-and-later ), OR
Shorten your CMAKE_INSTALL_PREFIX.

Hello JKSH,
thanks a lot for your answer.

yes you are right, I have already set:
"Disable the limit (https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd#enable-long-paths-in-windows-10-version-1607-and-later )"

But I will try now with shorten now.
Thanks.

Hello,
it works perfectly!
Now I just have to resolve the Qt VS Tools Exception "Illegal characters in path."
Thanks.
