原创 模拟QtEmbedded-4.5.2 在X86主机上

作者：孙晓明，华清远见嵌入式学院讲师。

【实验环境】

1、主  机：Fedora9 DVD 发行版
        2、目标机：虚拟机
        3、源码包：
        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、编译器  Fedora9 自带gcc version 4.3.0

1、解压源码：

[root@localhost ~]#mkdir  -p  /opt/Qt_X_E
        [root@localhost]# cd /opt/Qt_X_E

把下载的源码复制到这个目录

[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 ./

解压源码：

[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、配置编译Qt源码：

[root@localhost Qt_X_E]# cd qt-x11-opensource-src-4.5.2
        [root@localhost qt-x11-opensource-src-4.5.2]# ./configure

选择o确定开源版本，选择yes接受版权；

[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

会看到如下信息，已经生成qvfb（接下来会用到）：

/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、配置编译QtE源码X86版本：

[root@localhost Qt_X_E] # mv 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

选择o确定开源版本，选择yes接受版权；

[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/analogclock

看到如下信息：

/usr/local/Trolltech/QtEmbedded-4.5.2-x86/examples/widgets/analogclock/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、在qvfb上运行example代码

建立配置脚本

[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

添加如下内容:

QTEDIR=/usr/local/Trolltech/QtEmbedded-4.5.2-x86
        PATH= $QTEDIR/bin:$PATH
        LD_LIBRARY_PATH=$QTEDIR/lib:$LD_LIBRARY_PATH

保存退出.

[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

看到如下界面：
