Yes - thanks for the updates - I noticed that some of the links had been fixed too.
I'm currently reading a thread
in the Qt forums; it seems similar problems are caused when Visual Studio is already installed - the Qt configuration is using the INCLUDE and LIB system environment variables, which will be pointing to the Visual Studio installation. This could have caused the problem I described, and another one I'm now getting:
undefined reference to `CoCreateInstance@20'
I'm going start from the beginning, with LIB and INCLUDE set to the mingw dirs instead.
I'll have to figure out a better solution to switch between VS and MINGW.
