same filename cause multiple definition

[Neether]

I have 2 file

mainmodule/dispatcher.cpp
log4qt/dispatcher.cpp

just have the same name,there is no connection between this two files.

when I run build,I get "multiple definition" error.

I found same issue in here 13 years ago https://www.qtcentre.org/threads/40338-qmake-multiple-definition
and have no solution.

Don't use the same filename in one qmake project.

CMake became the "standard" or recommendation for Qt6+.
If you want to have your files named like this, you could move to CMake

@Neether You can always include log4qt by building it separately as a library (dynamic or static).

This has nothing to do with a 'feature' or similar. It's just a problem of duplicate symbols in your code - this is simply not allowed (even not in other programming languages).
