QT version is not properly installed, please run make install
linux, qt
Solution
Just so this no longer shows up as unanswered:
To install all qt-devel libraries, use
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
Problem
I installed QT-creator from a downloaded copy of `qt-creator-linux-x86-opensource-2.6.1.bin` using ``` sudo ./qt-creator-linux-x86-opensource-2.6.1.bin ``` in Ubuntu 11.04 I tried to add QT versions in QT-Creator/Build/QT-versions configuration and it asked for a qmake executable. I installed it using: ``` sudo apt-get install qt4-devel ``` which deployed qmake in `/usr/bin/qmake` I selected it in QT-Creator/Build/QT-versions configuration as manual, `Qt-4.7.2 (System) /usr/bin/qmake-qt4` but `QT version is not properly installed, please run make install` message appears and I can't use it in QT-Creator/Build/Kits configuration. How can I solve the problem and configure qmake for Qt-creator use in project creation?
