I don't think the problem is permission
QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project
Ok, I'm back. I don't know why but "qmake" is now working as it should on my stuff. I still can't use it on any of the Qt-4 examples however.
