Could neither create nor attach to shared memory segment.

Hi Folks,
I am running on a fresh installed Fedora 38. I was able to compile and installed correctly Tomahawk as root, using the Fedora howto from you.
If I execute tomahawk as root all is fine, however if I execute as user it is not, resulting in the following message not matter of ownerships:

[me@host build]$ ./tomahawk
QSocketNotifier: Can only be used with threads started with QThread
qt.qpa.qgnomeplatform.theme: The desktop style for QtQuick Controls 2 applications is not available on the system (qqc2-desktop-style). The application may look broken.
KDSingleApplicationGuard: Could neither create nor attach to shared memory segment.

0:11:58 [0]: virtual DownloadManager::~DownloadManager() Shutting down DownloadManager.
0:11:58 [1]: void DownloadManager::storeJobs(const QList<QSharedPointer >&)

any idears? I fear it has to do with "wayland"

Why as root? No idea if it's related, but Tomahawk should run fine in user context

[dschmidt]

Wayland shouldnt matter too much as it should be handled by Qt Platform Abstraction

Hi dscmidt - Thanks for your fast reply.
This is exactly what i want to do run the program as user - not as root , but then the error comes -- I just recompiled it as user, however it makes no difference. I did the first compilation as root as I want this program finnaly not end up in my home rather then in for example in /opt /or /usr/local .
However it makes anyway no difference if I compile it as user or root , as long as I chown -R the whole directory to user or root
