I'm testing an application using Qt 4.7.3 compiled with MinGW on a clean XP virtual box. The application wasn't working and after much grief, I traced the error to needing to download the Visual C++ 2005 redistributable. I downloaded this and it worked. Something doesn't seem right here, shouldn't I not need any VC++ libraries since I'm using MinGW? Could it be a problem with my compilation? I should mention that I'm not using qmake to build.

How do you think Qt interfaces with windows, magic? ;) – Brian Roach Oct 25 '11 at 00:49

We have had same problem with qt 5.0.1 but the problem wasn't in msvcrt. Standard qt application also requires libEGL.dll from qt mingw folder. – bartolo-otrit Apr 11 '13 at 13:46

The dependency on MSVCRT.DLL is due to MinGW itself. To quote mingw.org..
MinGW provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs. (It does depend on a number of DLLs provided by Microsoft themselves, as components of the operating system; most notable among these is MSVCRT.DLL, the Microsoft C runtime library.

I had read through that (mostly) - perhaps I need to read it more thoroughly. It sounds to me like they are saying the VC++ libs are needed only when compiling with Visual Studio. – buck Oct 25 '11 at 01:05
