How that?

https://wiki.qt.io/Coding_Conventions#Things_to_avoid says:

"Avoid the use of anonymous namespaces in favor of the static keyword if 
possible."

While 
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rs-unnamed2 
says:

"Consider putting every definition in an implementation source file in 
an unnamed namespace [...]"

Either I am missunderstanding something, or Qt Coding Conventions and 
C++ Core Guidelines strongly disagree on whether to use anonymous 
namespaces.
