I've got problems trying to cross-compile an app for windows on Linux Mint x64 following this. (I also got Qt5.4.2 installed.)
Building Qt 5 on Linux, for Windows
The error shows up when running [mxe root]/usr/bin/i686-w64-mingw32.static-qmake-qt5 . Of course I changed [mxe root] to fit the mxe directory.
Any ideas?
My question is pretty similar to this one. Project ERROR: Unknown module(s) in QT: webkitwidgets
It'd be nice not to mark it as duplicate, as was done with that question, because, like @Petr already mentioned in the comments there, the two questions are not related.
