Description of bug

Cannot launch the application. Trying to launch it from the terminal results in this error:

warning: direct reference to protected function '_ZNK19QStyledItemDelegate15initStyleOptionEP20QStyleOptionViewItemRK11QModelIndex' in '/usr/lib/libQt6Widgets.so.6' may break pointer equality
pollymc: _ZNK19QStyledItemDelegate15initStyleOptionEP20QStyleOptionViewItemRK11QModelIndex: /usr/lib/libQt6Widgets.so.6: error due to GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS

Steps to reproduce

Run it through the terminal. (This was done just to get the error message)

[Operating System : Arch Linux]

Suspected cause

Seems to be a problem with one of the Qt6 widget files.

This issue is unique

• [x] I have searched the issue tracker and did not find an issue describing my bug.

See https://github.com/PrismLauncher/PrismLauncher/issues/991, for the time being use either pollymc or pollymc-qt5-bin instead.

Trying to build pollymc gives the following error:

I'm not sure if this is just a problem with Java while trying to build with it in a chroot environment.

[fn2006]

You need to use Java 17, Java 20 doesn't work.

[spxcewolf]

For some reason it seems to be downloading JDK20 even after choosing JDK17. Seems to be some other problem with my install environment.

[fn2006]

Have you tried using archlinux-java to set Java 17 as the default?

[spxcewolf]

I did, but Java was weirdly removed from the chroot after every error. I built it in a new chroot and it works now. Thanks.

This is still an issue because pollymc-bin doesn't run, reopening this until it gets fixed upstream by Prism.
