qmake: could not find a Qt installation of ''
This thread was not of any help to me. qmake: could not find a Qt installation of ''.
How can I get qmake to recognize where the Qt folder is?
Right now it is installed in /opt/Qt5.1.0.

Try to run qmake by full path e.g. `/opt/Qt5.1.0/bin/qmake`. – Pavel Strakhov Jul 29 '13 at 07:33

I get the same error message. – ShrimpCrackers Jul 29 '13 at 07:41

I think it's because my Qt installation directory need to be setup in $PATH. Any good tutorials on setting up $PATH environment vars? – ShrimpCrackers Jul 29 '13 at 07:49

With mentioning /opt in your question, I assume that you're using linux, in which case: http://superuser.com/questions/488173/how-can-i-edit-the-path-on-linux – TheDarkKnight Jul 29 '13 at 07:59

Have you installed the qt5-default ? You need to do this in addition to running the Qt supplier .run file.
sudo apt-get install qt5-default

3qt5-default brings 131 other packages with it. I want to use qmake on a remote server where I don't need any x11 packages at all. How could I avoid all this x11-bull-shit installation but get qmake working well? – arilou Jul 11 '16 at 09:03

This message shown by qtchooser app. To setup it properly, you should make conf files in /etc/xdg/qtchooser/
for example:
$ ls -1 /etc/xdg/qtchooser/
default.conf
qt-4.8.5.conf
qt-5.1.0.conf
each file has two lines: path to bin, path to lib:
$ cat /etc/xdg/qtchooser/default.conf
/opt/Qt/4.8.5/bin
/opt/Qt/4.8.5/lib
additional info: man qtchooser

The solution for me on this problem was to specify the QT version, as this message was being generated by /usr/bin/qtchooser
So in my case, it was QT4 I was trying to use, and running:
qmake
generated the error (could not find a Qt installation of '')
qmake -qt=qt4
fixed that error though. In my case, it was a Ruby Gem trying to compile with qmake, so I couldn't get it to pass in that extra command line argument, so I instead added this to my profile
export QT_SELECT=qt4
And now QT4 runs just fine on my Ubuntu system.

For me the symlink to default.conf was missing in /usr/share/qtchooser. It wasn't enough to put it into /etc/xdg/qtchooser.
