Yes.

The reason is that qmake puts all the object files from the compiler in 
the same directory.

I agree completely qmake should at least warn about this problem, maybe 
even treat it as an error. But that's not the case, unfortunately. You 
could write a bug report about this, if it doesn't already exist.

None. You rename the files.

Well, you can do this by creating a static library by one project and 
link to this project with the other project. In that case, there is of 
course no problem with the two having the same filename, if the build 
dir isn't also named the same.

But when you use .pri files, you just have to accept that you can't have 
two cpp files with the same name. Probably also goes for ui files, qrc 
files etc.
