Method 1

Http://qt.nokia.com/downloads to download the corresponding version, such as linux32-bit.

Method 2

Download the source package, such as the latest http://qt.nokia.com/downloads/linux-x11-cpp

1) configuration: Enter the decompressed folder and run./configure-prefix/usr/local/Trolltech/Qt-4.7.4-pc
2) Compile: make (long time, several hours)
3) installation: make install (because the installation directory is specified during configuration, it will be installed under the Directory:/usr/local/Trolltech/Qt-4.7.3-pc)
4) then set the qt path, which can be added to home/user/. profile.

QTDIR =/usr/local/Trolltech/Qt-4.7.4
PATH = $ QTDIR/bin: $ PATH
MANPATH = $ QTDIR/man: $ MANPATH
LD_LIBRARY_PATH = $ QTDIR/lib: $ LD_LIBRARY_PATH

Export qtdir path manpath LD_LIBRARY_PATH

An error occurs during compilation. The solution is to install three packages sudo apt-get install libX11-dev libXext-dev libXtst-dev
