Building QT6.5 with NMake error
-
Hello all,
I am getting an error when building Qt6. It is getting stuck on qt6qml_debug_metatypes.json
Below is the output of the error:
Error 5 while parsing C:/Users/Phillip/source/qt6-build/qtdeclarative/src/qml/meta_types/qt6qml_debug_metatypes.json: illegal value NMAKE : fatal error U1077: 'call ..\..\..\.qt\bin\qt_setup_tool_path.bat C:/Users/Phillip/source/qt6-build/qtbase/bin/qmltyperegistrar.exe --generate-qmltypes=C:/Users/Phillip/source/qt6-build/qtbase/qml/QtQml/Base/plugins.qmltypes --import-name=QtQml.Base --major-version=6 --minor-version=5 --follow-foreign-versioning @C:/Users/Phillip/source/qt6-build/qtdeclarative/src/qml/qmltypes/Qml_foreign_types.txt --private-includes -o C:/Users/Phillip/source/qt6-build/qtdeclarative/src/qml/qml_qmltyperegistrations.cpp C:/Users/Phillip/source/qt6-build/qtdeclarative/src/qml/meta_types/qt6qml_debug_metatypes.json' : return code '0x1' Stop.

There is nothing in it so I think that this is the issue as it is suppose to have contents in it.
Has anyone else ran into this issue before?

Looks at lot like QTBUG-94942 from a few dot releases ago. Some changes were made to fix this in 2021.

Interesting. This error was generated when compiling 6.5.2 I guess the bug fix didn't get to this version?
-
I guess I will need to merge the changes for the specific files from the dev branch into the installation of 6.5.2 source to fix the issue?

@Omni_Philm According to the bug report it was fixed in 6.1.3

@jsulm So if it is fixed, why do I still have an issue? should I open a bug report?
@Omni_Philm Maybe it is not the same issue as the one @ChrisW67 posted.

I just ran into this (on Windows) with 6.5.3. It does seem like the bug has reemerged (some kind of regression). The original bugfix was in
Qt6CoreMacros.cmake(https://codereview.qt-project.org/c/qt/qtbase/+/360385), and that file has changed a lot since then, so I think the issue crept back in.I will try to create a minimum reproduction and post to Qt bugtracker.

Try it with a recent Qt version before. I don't think this will be fixed when it's only in Qt6.5 esp. since the official way to build Qt is ninja and not nmake.

Yes. I will also try the most recent.

Ah. You have called my attention to my accidental "thread hi-jacking" (minor?). I am not building the Qt framework. I am using CMake and the Qt-provided CMake functions to build a Qt/QML project. (There will be a reproduction from me in a few days. I'm swamped right now but have confidence I can reproduce this.)
Once I reproduce it, either a bug can be opened or I can at least document (if so) that a more recent Qt fixes it.

As expected, it was easy to make a very small CMake project to reproduce the error (building "with" Qt, as opposed to "building Qt" the whole framework).
The small project reproduces the qt6qml_debug_metatypes.json nmake
"illegal value"error (invalid empty json file).There is good news, just as @Christian-Ehrlicher alluded to.
It reproduces easily in 6.5.3, but the problem is gone when I use 6.7.3.
So if anyone arrives here (as I did) due to a 6.5.3-based Qt project and is looking for a simple fix, the simple fix appears to be: upgrade to at least 6.7.3.
