Hi and welcome to devnet,
If a symbol is missing, it might mean that the version of the library you have on your system is widely different than the one used to build Qt.
-
Which distribution are you using ?
Multiple possible things:- use your distribution provided Qt if it's recent enough for your project
- build and use your own version of that dependency
- build Qt yourself
- change Linux distribution

I am using fedora 40, i installed Qt from its online installer, everthing works and is linked properly, until i use multimedia or multimedia widgets.
@bishal said in libgssapi_krb5.so file not found while using Multimedia and MultimediaWidget even though it is present in /usr/lib64:
i installed Qt from its online installer,
You mean you installed Qt using Qt Online Installer?
If so please try with Qt provided by Fedore like @SGaist suggested.
