Yes, it is.
I just re-compiled Qt using the installation package (.exe), and now it works.
I can think of two possible reasons for this:
1) The installation package warned that my MinGW version is too new, which may lead to problems. Therefore I let the installer download the proper (older) MinGW.
2) It turned out I have some other versions of QtCore4.dll, for example in the MikTeX\bin directory, which was *also* in my PATH. This time I've put the path to Qt\bin in front of all the other directories in the PATH string, so that the correct dll will be found first.
I think one of these two options solved my problem.
Bug80, what version you MinGW did you use for the first time?
I'm a rebel in the S.D.G.
The latest version (5.1.4). I believe this comes with GCC 3.4.5
I don't know which version of MinGW comes with Qt (any ideas as to how to find that out?). The GCC version is 3.4.2.
I remember the installer of Qt complaining about an incorrect version of w32_api.h with the newer GCC version.
