qt-4.8.4 installation and environment variable configuration

Install QT:PC for different platforms in Linux, Embedded X86;arm.

These three PC version, embedded X86 version and ARM version of the difference is mainly reflected in: When the Configure were added different parameters, the specific difference is:

PC platform (X11 platform): Full QT installation in Linux, use it to compile the program, directly with "./" can be run.
Embedded X86 platform: With QVFB function, on the PC can simulate the operation of the application on the arm Development Board. With this compiled program, only the "./" command cannot be run, you must add the parameter [-QVFB]–QWS
Ps: Embedded X86 platform, this is a PC under the Qtopia, he has a simulator, can simulate the appearance of the arm Development Board. Convenient commissioning;
ARM platform: A compiled program for running on an arm platform.
Ps:arm platform, this is mainly used to compile, because to download to the Development Board, requires the arm version of the QTE library files, compiled directly to the Development board after the download run;

Ps: Compiling x86 is to get MAKEQPF, compiling PC is to get QVFB

A. Installing the QT on the PC platform
1) configuration: Run./configure-prefix/usr/local/qt-4.8.4-x11
2) Compile: Make (time is longer)

3) Install: Make install (because the installation directory is specified in the configuration, this will be installed in the directory/usr/local/qt-4.8.4-x11)

B. Installing the ARM platform qt/e
1) configuration: Go to CD Qt-4.8.4-arm and run
