Qt debug and release

[cmaxb]

Anybody understand what Qt is doing? When I qmake a project file, three makefiles are created, regular, Makefile.debug, and Makefile.release. In c::b, I build a project in debug mode, everything runs fine. When I switch to Release, I hit build and I see "g++ -o2 ..." etc. The file I was editing is compiled with optimization but then, I enter the link stage immediately. All object files go to the same folder, so I don't see how it can link in that file immediately and create an executable. The running executables are maybe 5% difference in memory

nobody knows about Qt. and uses an external Makefile?
