Error 'isRelocatable': undeclared identifier.

wasimIM

Hi all,

I have integrated few QT libraries in my desktop project. Previously used an older version of QT, currently updated it to 6.7.3. I am facing a build error of " 'isRelocatable': undeclared identifier. " after building my solution. I am building using visual studio 2022. I tried both versions of QT 6.7.3 and 6.8.1 issue reproduces for both the versions. I see a similar bug here, tried disabling /Zc:twoPhase- but prompts me with another compiler error saying two-phase name lookup is not supported for C++/CLI. any solutions to it? Could someone please help me with it.

Thanks

'isRelocatable': undeclared identifier.

From where is it coming? You really should provide more context and the full error message.

@jsulm I have included few headers into my project. Sharing an image below. and the errors where it points to.

@wasimIM It looks like you have a linker error, but you hide the relevant information there, so don't know

@jsulm the linking error was due to the above compile error use nativeTerritoryName() instead. I have changed that. Now both first compile error and second link error has gone, only remaining with 'isRelocatable' errors.

It directs to this macro definition inside qtypeinfo.h, here if we remove the static_assert, then it builds fine.

I think that is as per the https://bugreports.qt.io/browse/QTBUG-123922 you referenced. A post there says

isRelocatable is both defined and used there.

Between 6.6 and 6.7, we added that static_assert (in ff7d69dafda2f2cdc3a93f76ed8f77a113ac1a1c), so it has to be the reason why it is failing now. But there's nothing wrong with this code.

I think they are saying there is nothing wrong with the code but there is with MSVC 2022. Not sure that code is going to get changed by Qt.

@jsulm any solutions you see? Or do I need to provide any other info?

@wasimIM I don't have a solution. Maybe try with more recent MS compiler if there is a newer version?
