I'm running linux mint 17.1 cinnamon 64bit and installed qtcreator from repo, The problem is I don't find any qt version in Tools->options->qt versions.
I tried downloading qt from here http://www.qt.io/download/, I installed the community version in home and removed qtcreator that was installed from repo, I also removed qt4-doc and qtcreator-doc and relied on the installation in home directory.
I also tried installing qmake version 5 from repo but qtcreator still doesn't detect any qt, I thought of adding it manually by browsing to /usr/bin/qmake but it said it's not an executable.
I need the program for a university project which is a simulation program, so basically , it's a desktop application. I'm planning to use qt Quick project type but as I said, no qt version detected, although gcc compilers are detected(I installed them from repo).
I have qtcreator 3.3.1 based on qt 5.4(as the about says).
I tried removing the installation from home folder and instead of installing qtcreator, I ran
apt install qt-sdk which apparently installs qtcreator too, but I still find no qt version in Tools->options->qt versions.
