Simulation QtEmbedded-4.5.2 on x86 host

Author:Sun Xiaoming, a lecturer at Huaqing vision embedded College.

[Lab environment]

1. Master: Fedora9 DVD release
2. Target machine: Virtual Machine
3. source code package:
Ftp://ftp.qtsoftware.com/qt/source/Qt-x11-opensource-src-4.5.2.tar.gz
Ftp://ftp.qtsoftware.com/qt/source/Qt-embedded-linux-opensource-src-4.5.2.tar.gz
4. the compiler Fedora9 comes with gcc version 4.3.0

1. Extract the source code:

[Root @ localhost ~] # Mkdir-p/opt/Qt_X_E
[Root @ localhost] # cd/opt/Qt_X_E

Copy the downloaded source code to this directory.

[Root @ localhost Qt_X_E] # cp/root/share/ Qt-x11-opensource-src-4.5.2.tar.gz ./
[Root @ localhost qt_x_e] # cp/root/share/qt-embedded-linux-opensource-src-4.5.2.tar.gz ./

Decompress the source code:

[Root @ localhost qt_x_e] # tar xzvf qt-x11-opensource-src-4.5.2.tar.gz
[Root @ localhost qt_x_e] # tar xzvf qt-embedded-linux-opensource-src-4.5.2.tar.gz

2. Configure and compile the QT source code:

[Root @ localhost qt_x_e] # cd qt-x11-opensource-src-4.5.2
[Root @ localhost qt-x11-opensource-src-4.5.2] #./configure

Select o to determine the open-source version, and select YES to accept copyright;

[Root @ localhost qt-x11-opensource-src-4.5.2] # Make
[Root @ localhost qt-x11-opensource-src-4.5.2] # make install
[Root @ localhost qt-x11-opensource-src-4.5.2] # cd tools/qvfb
[Root @ localhost qvfb] # Make
[Root @ localhost qvfb] # make install
[Root @ localhost qvfb] # cd ../../../
[Root @ localhost qt_x_e] # file qt-x11-opensource-src-4.5.2/bin/qvfb

The following information is displayed, and qvfb has been generated (which will be used later ):

/Opt/qt_x_e/qt-x11-opensource-src-4.5.2/bin/qvfb: Elf 32-bit LSB executable, Intel 80386, Version 1 (sysv), dynamically linked (uses SHARED libs ), for GNU/Linux 2.6.9, not stripped

3. Configure and compile the QTE source code x86 version:

[Root @ localhost qt_x_e] # Music qt-embedded-linux-opensource-src-4.5.2 qt-embedded-linux-opensource-src-4.5.2-x86
[Root @ localhost qt_x_e] # cd qt-embedded-linux-opensource-src-4.5.2-x86
[Root @ localhost qt-embedded-linux-opensource-src-4.5.2-x86] #./configure-Prefix/usr/local/trolltech/QtEmbedded-4.5.2-x86-embedded x86-qvfb

Select o to determine the open-source version, and select YES to accept copyright;

[Root @ localhost qt-embedded-linux-opensource-src-4.5.2-x86] # Make
[Root @ localhost qt-embedded-linux-opensource-src-4.5.2-x86] # make install
[Root @ localhost qt-embedded-linux-opensource-src-4.5.2-x86] # CD ..
[Root @ localhost qt_x_e] # file/usr/local/trolltech/QtEmbedded-4.5.2-x86/examples/widgets/analogclock

The following information is displayed:

/Usr/local/trolltech/QtEmbedded-4.5.2-x86/examples/widgets/analogclock: Elf 32-bit LSB executable, Intel 80386, Version 1 (sysv ), dynamically linked (uses SHARED libs), for GNU/Linux 2.6.9, stripped

[Root @ localhost qt_x_e] # cp qt-x11-opensource-src-4.5.2/bin/qvfb/usr/local/trolltech/QtEmbedded-4.5.2-x86/bin

4. Run the example code on qvfb.

Create a configuration script

[Root @ localhost qt_x_e] # cd/usr/local/trolltech/QtEmbedded-4.5.2-x86
[Root @ localhost QtEmbedded-4.5.2-x86] # Vim setenv-x86.sh

Add the following content:

Qtedir =/usr/local/trolltech/QtEmbedded-4.5.2-x86
Path = $ qtedir/bin: $ path
LD_LIBRARY_PATH = $ qtedir/lib: $ LD_LIBRARY_PATH

Save and exit.

[Root @ localhost QtEmbedded-4.5.2-x86] # source setenv-x86.sh
[Root @ localhost QtEmbedded-4.5.2-x86] # cd/examples/widgets/analogclock
[Root @ localhost analogclock] # qvfb-width 640-height 480 &
[Root @ localhost analogclock] #./analogclock-qws
