Build a Linux QT Development Environment

For more information, see http://www.doc88.com/p-59138565158.htmland QT doc.

First download the source code
Qt-creator-2.4.1-src.tar.gz graphics Development Environment
Qt-everywhere-opensource-src-4.8.0.tar.gz QT source code, compiled into QT library and qmake

Decompress the package to the system.
All QT-related files of mkdir/usr/local/QT are defined in this directory for ease of management.
Tar xvf qt-everywhere-opensource-src-4.8.0.tar.gz-C/usr/local/QT/
Tar xvf qt-creator-2.4.1-src.tar.gz-C/usr/local/QT/

Create a directory
Mkdir/usr/local/QT
Mkdir/usr/local/QT/qt_x11: Compile the library path for running the QT program on the PC.
Mkdir/usr/local/QT/qt_embeded_x86 compile the library path for simulating qvfb running QT program on PC
Mkdir/usr/local/QT/qt_arm
Mkdir/usr/local/QT/qvfb
Mkdir/usr/local/QT/Shell stores the shell script directory for setting the library Environment Variables

To install the Lib required by QT, see: Doc \ HTML \ requirements-x11.html to compile the lib on which X11 depends

1. Set up the PC version, that is, X11 installation. You can refer to the file in the source code.
/Doc/html/requirements-x11.html install X11 before the library to install, QT dependency
/Doc/html/install-x11.html install QT Method

A) Qt library Compilation
CD/usr/local/QT/qt-everywhere-opensource-src-4.8.0
./Configure-Prefix/usr/local/QT/qt_x11
Make
Make install

B) Qt LIBRARY PATH settings
CD/usr/local/QT/Shell
Touch setenv_qt_x11.sh
Vim setenv_qt_x11.sh
Add the following in setenv_qt_x11.sh:
##########################

Qtdir =/usr/local/QT/qt_x11
Path = $ path: $ qtdir/bin
Manpath = $ manpath: $ qtdir/doc/man
LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ qtdir/lib
Export qtdir path manpath LD_LIBRARY_PATH

##########################

2. x86 version (required when running QT qvfb)
A) Qt library Compilation
CD/usr/local/QT/qt-everywhere-opensource-src-4.8.0
./Configure-Prefix/usr/local/QT/qt_embeded_x86-embedded x86-qvfb (-qvbf indicates compiling virtual framebuffer, which is used by the simulator)
Make
Make install

B) Qt LIBRARY PATH settings
CD/usr/local/QT/Shell
Touch setenv_qt_embeded_x86.sh
Vim setenv_qt_embeded_x86.sh
Add the following in setenv_qt_embeded_x86.sh:
##########################

Qtdir =/usr/local/QT/qt_embeded_x86
Path = $ path: $ qtdir/bin
Manpath = $ manpath: $ qtdir/doc/man
LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ qtdir/lib
Export qtdir path manpath LD_LIBRARY_PATH

##########################

3. Embedded ARM QT
A) Qt library Compilation
CD/usr/local/QT/qt-everywhere-opensource-src-4.8.0
./Configure-Prefix/usr/local/QT/qt_arm-Embedded ARM
Make
Make install

B) Qt LIBRARY PATH settings
CD/usr/local/QT/Shell
Touch setenv_qt_arm.sh
Vim setenv_qt_arm.sh
Add the following in setenv_qt_arm.sh:
##########################

Qtdir =/usr/local/QT/qt_arm
Path = $ path: $ qtdir/bin
Manpath = $ manpath: $ qtdir/doc/man
LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ qtdir/lib
Export qtdir path manpath LD_LIBRARY_PATH

##########################

4. Compile the qvfb Tool
A) qvfb Compilation
CD/usr/local/QT/qt-everywhere-opensource-src-4.8.0
CD./tools/qvfb
Make
CP.../bin/qvfb/usr/local/QT/qvfb
Otherwise:
CD // usr/local/QT/qt-everywhere-opensource-src-4.8.0/src/plugins/gfxdrivers/qvfb
Qmake
Make install

5. Run the QT program on the PC:
Write code
Qmake-Project generation. Pro
Qmake
Make

6. the QT Program specifies the installation path.
Add the following in the. Pro file:
Target. Path =/usr/local/MyApp
Target. Files = *. cpp qtdemo
UNIX: target. Extra = LS & Echo 1
Instballs + = Target

7. ubutu directly sudo apt-Get install libqt4-dev directly install QT library, and then set the environment variables on OK
