Problems with Qt6.4

[Raindrop7]

Hello, I have installed Qt6.4 on my Fedora 37.
Everything works just fine but I have two issues:

echo $QTDIR
it points to old Qt4 not the one in home/qt/6.4

2- When I set up Qt for android, I have set the java folder as:
/lib/jvm/OpenJdk19
but the box below says:
java path exists and writable (in red cross error).

• If I download java and extract it on my home folder then point Qt to it, it works fine!
  So why Qt complains about java in /lib/jvm/Openjdk?

That environment variable should only be set locally (e.g. in your build script). It should not be set globally.

The validation code is available at https://github.com/qt-creator/qt-creator/blob/v9.0.1/src/plugins/android/androidsettingswidget.cpp#L531-L537

Does /lib/jvm/Openjdk exist, and does /lib/jvm/Openjdk/bin/javac exist?

@JKSH it does exist however now it works fine although i see red cross on "java path exists and writable".

Interesting. Does the red cross persist if you reboot your computer?

I just want to note, on my fedora 39 machine I had to install java-17-openjdk-devel,
then reopen the qt options window and the error went away
