Erro trying to run on Fedora 40

[IagoJevaux]

After installation using 'dnf install goverlay', it doesn't work

When running on terminal the following error is presented: /usr/libexec/goverlay: symbol lookup error: /lib64/libQt6Pas.so.6: undefined symbol: _ZNK7QString12isSimpleTextEv, version Qt_6

DIdn't try to build from source due Lazarus Dependecy hell.

Exact same issue on Fedora 40, since it's giving us a Qt6 error we should probably be looking into changes to Qt made between fedora 39 and 40 in qt.

Good afternoon, I have the same problem Gnome 46 Fedora 40

I don't think it's a QT6 error by itself. The issue points to /lib64/libQt6Pas.so.6, which is a Lazarus library. If someone has a working Lazarus in Fedora 40 maybe trying to compile from source might give a bit more information.

[Ironfist69]

same issue, I'm also using Fedora 40

[conmar1001]

Same issue running fedora kde 40.

[aj53108]

Can confirm, same issue on Fedora 40 KDE.

I can give it a try to compile from source

Well didn't get very far with building it from source, here's the error message.

Also not imposible that I messed something up with dependencies but maybe someone better at figuring out error codes may find this useful.

[AndreCox]

Also managed to track down this issue on the latest version of lazarus

- nothing provides fpc = 3.2.2-1 needed by lazarus-3.2-0.x86_64 from @commandline

Hey guys, i didn't test on Fedora but i think the repo that provides the ubuntu libqt6pas also provides a rpm package. Check if it works

The updated files are in the Fedora Rawhide repo. I uninstalled goverlay then installed from rawhide and it works fine.

Didn't work for me. Downloaded version goverlay-1.1.1-2.fc40.x86_64 from rawhide and same error. Can you provide a link and installation method used?

I think it was: sudo dnf remove goverlay sudo dnf remove libqt6pas6 libqt6pas6-devel sudo dnf --enablerepo=rawhide install goverlay

The devel package might not be installed, if so just ignore it.

Are you sure you did this in a clean fedora 40? libqt6pas6 libqt6pas6-devel are not installed and I can't install them on F40 because the only available source (https://github.com/davidbannon/libqt6pas) is based on qt6 6.2 and F40 ships with qt6 6.7... Also, "sudo dnf --enablerepo=rawhide install goverlay" returns with "unkown repo: rawhide".

You have to add the repo. sudo dnf install fedora-repos-rawhide

[IagoJevaux]

You have to add the repo. sudo dnf install fedora-repos-rawhide

Is it safe to add rawhide repo? I had a bad experience in the past when I enabled rawhide systemwide. Since then I didn't try to enable it ever again (thought that they might have added a way to fetch packages from rawhide without having to enable the repo - silly me).

You are just adding the repo and installing a few packages from it. It's fine. It will only install goverlay and required dependecies.

sudo dnf install fedora-repos-rawhide sudo dnf --enablerepo=rawhide install goverlay

Didn't work, same error when installing from rawhide...

The goverlay-1.1.1-2.fc40.src.rpm update has arrived on Fedora 40, everything works, thank you!

Actually Lazarus updated with a fix to QT6Pas. It's working now.

Issue closed.
