I also looked into compiling the source code which is often as easy as
following some simple instructions. The compile makes use of qmake
which gives the error:
qmake: could not exec '/usr/lib/i386-linux-gnu/qt4/bin/qmake': No such
file or directory
/usr/bin/qmake is a link that points to /usr/bin/qtchooser which is
picking the wrong version of qt. Qt5 is needed and is installed. I
have set an environment variable QT_SELECT=qt5 but the chooser is not
fooled. So, if the binary is not usable how do I select qt5?
I think you have the qtchooser syntax wrong.
'man qtchooser' says that the value passed to QT_SELECT is the same as
that which would be passed to 'qtchooser -qt='. Testing that, I get:
$ qtchooser -qt=4 -print-env
QT_SELECT="4"
QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt4/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"
wanderer@apologia:~$ qtchooser -qt=5 -print-env
QT_SELECT="5"
QTTOOLDIR="/usr/lib/qt5/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"
$ QT_SELECT=4 qtchooser -print-env
QT_SELECT="4"
QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt4/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"
IOW: the value you need to pass in is '5', not 'qt5'.
