QT dll names

The QT dlls come in pairs: NAME.dll and NAMEd.dll , for the release and debug versions. However, on my link line, I only ever mention NAME.lib . How does the linker arrive at NAMEd.dll for the dynamic link, in the case of a debug build?

qmake handles this behind the scenes when you call module include like
QT += gui. -
@sierdzio I don't use qmake, just regular make, and I can see the link command line has only NAME.lib .

oh, then it means I was wrong. Interesting! Maybe the linker is clever enough to handle this case? Or maybe you are building debug (your app) but linking release Qt?

dumpbin /dependentson both the debug and release versions of my util, and they have the same release QT dlls. I guess I never had to step into the QT code :-) . Usually, I get link errors when mixing debug with release, stemming from different array instrumentations. Sounds like QT was careful about this, to allow the mixing of debug with release -- unix-like.
