【實驗環(huán)境】

1、主 機：Fedora9 DVD 發(fā)行版

2、目標機：虛擬機

3、源碼包：

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、編譯器 Fedora9 自帶gcc version 4.3.0

1、解壓源碼：

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

[root@localhost]# cd /opt/Qt_X_E

把下載的源碼復制到這個目錄

[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 ./

解壓源碼：

[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、配置編譯Qt源碼：

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

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

選擇o確定開源版本，選擇yes接受版權(quán)；

[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

會看到如下信息，已經(jīng)生成qvfb（接下來會用到）：

/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、配置編譯Qte源碼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

選擇o確定開源版本，選擇yes接受版權(quán)；

[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上運行example代碼

建立配置腳本

[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

添加如下內(nèi)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：
