it would be cool to have it auto generate the ui_mainwindow.h file too
uic mainwindow.ui -o ui_mainwindow.h
Cool. Could you update it to use with qt5?

This was very helpful for me #@mroavi. Thank you 👍
This variant is pretty much useless to anyone doing anything modern, but if you're using Qt2 or Osiris (which is my modernized-ish fork of Qt2.3.2), here's a modified version that should work with Qt2 and Osiris. If using Qt2, change $(OSIRISDIR) to $(QTDIR). You'll still need to manually run uic before running make if you're using .ui files.

@habaneropep2019 it is as old as mammoth shite. I'm working on time series rendered on GPU and QML.
@mishurov is there any chance I could get your permission to include your makefile with my Qt fork, under GPLv2 or BSD?
Why even ask that. Sure, of course. I'm not a lawyer. Everything I share, it is for public use.
