Error-

$ qmake qmake: could not find a Qt installation of ''

I installed Qt Version 4.8.2

Partial File of .profile in my home directory

set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
PATH="/usr/local/Trolltech/Qt-4.8.2/bin:$PATH"
PATH="/home/user/qt-everywhere-opensource-src-4.8.2/bin:$PATH"
export PATH
fi

How to make qmake work? Which one is the correct path for qmake?

[andreyc]

All of them are correct qmakes. You can have as many Qt installations as you need. If you need to use some particular installation then run qmake with full path. For example:
@
/home/username/qt-everywhere-opensource-src-4.8.2/bin/qmake
@
