want to downgrade Creator

mzimmers

Hi all -

I've been away from Qt-land for a bit, so I'm scraping the rust off my memory. Last year, I upgraded to Qt Creator 6.0.2 (but I'm still using Qt 5.15.2). Since then, I've been having various issues related to the debugger. I'd like to go back to the prior version of Creator. Can someone remind me how to do this? I can't find the way using the maintenance tool.

Thanks...

Qt creator 6.0.2 is the latest version, it was released end of last year.

However, there was to my knowledge never a creator 5.15.2, but this matches the latest open source release of Qt libs. Therefore, I think you are confusing something here. Maintenance shall give you the opportunity to install all older versions of Qt libs. Please check again.

If you really need to downgrade Qt creator you need to go to the archives and install an older version. https://download.qt.io/archive/qtcreator/

Hi koahnig - I wasn't clear in my OP: I'm using the Qt libraries 5.15.2, not Creator which, as you said, didn't exist at that version number.

Maybe it's not Creator, but an old app that used to build and run now gives me an error when I try to debug:

can't find linker symbol for virtual table for `ModelApScan' value
section .gnu_debuglink not found in C:\Qt\5.15.2\mingw81_32\plugins\platforms\qwindows.dll.debug
section .gnu_debuglink not found in C:\Qt\5.15.2\mingw81_32\plugins\styles\qwindowsvistastyle.dll.debug

ModelApScan is one of my classes. I get the .gnu_* messages when I try to execute this line:

    QApplication a(argc, argv);

Like I said, this used to build and run without incident, and I haven't changed the app. Not sure what's going on...

EDIT: this question is completely different from my original. I'll mark this solved and open a new question. Thanks...
