PS: all libraries are present

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.

[bishal]

So, how can i fix this problem. any suggestion please

[SGaist]

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

[bishal]

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:

You mean you installed Qt using Qt Online Installer?
If so please try with Qt provided by Fedore like @SGaist suggested.
