Could it be that the .ui needs manual fix? > The header is generated by uic, so either its not run at all because the header is still there or the wrong uic is run. I'd start with a fresh empty directory, copy a freshly extracted version of the software into that directory so there cannot be any hidden directories with cached files and then ensure that PATH does not contain any qt4 binary, in particular not uic, qmake, moc or rcc. If that works then you'll most likely find some screwup in your environment or some leftovers still in your original project directory. If it still fails I'd check what the Makefile contains for uic invocation and what version that is. if its qt4 but inside a qt5 install I'd reinstall qt5. Andreas
