内容:
step1. 将qt-embedded-linux-opensource-src-4.5.1.tar.gz拷贝到Linux下，解压缩：
# tar zxvf qt-embedded-linux-opensource-src-4.5.1.tar.gz
# cd qt-embedded-linux-opensource-src-4.5.1
step2. 配置选项并安装,也可以下载安装脚本qte_for_x86.sh：
#./configure \
-release \
-shared \
-no-largefile \
-qt-sql-sqlite \
-plugin-sql-sqlite \
-xmlpatterns \
-exceptions \
-svg \
-webkit \
-qt-zlib \
-qt-gif \
-qt-libtiff \
-qt-libpng \
-no-libmng \
-qt-libjpeg \
-make libs \
-make tools \
-nomake examples \
-nomake docs \
-no-nis \
-no-cups \
-no-iconv \
-no-dbus \
-no-openssl \
-xplatform qws/linux-x86-g++ \
-embedded \
-qt-freetype \
-depths 16 \
-qt-gfx-qvfb \
-no-gfx-transformed \
-no-gfx-multiscreen \
-no-gfx-vnc \
-no-gfx-linuxfb \
-qt-kbd-tty \
-no-kbd-usb \
-qt-kbd-qvfb \
-qt-mouse-pc \
-qt-mouse-qvfb \
-no-glib \
-feature-THREAD \
-feature-CONCURRENT \
-feature-SOUND \
-feature-EFFECTS \
-feature-QWS_MULTIPROCESS \
-silent
#make >log_make 2>&1
#make install >log_install 2>&1
step3. 设置环境变量（两种方法）：
仅当前用户有效（其他用户无效）：修改$HOME/.bash_profile,加入：
PATH=/usr/local/Trolltech/QtEmbedded-4.5.1/bin:$PATH
立即生效：
#source $HOME/.bash_profile
所有用户有效（包括root和普通用户）： 修改/etc/profile,加入以下行（一般在最后一行添加）：
export PATH=/usr/local/Trolltech/ QtEmbedded-4.5.1/bin:$PATH
立即生效：
#source /etc/profile
step4. 在PC机上运行Qt-Embedded程序的方法为： 使用Qt-Embedded for x86的Qt库来编译Qt-Embedded程序，然后使用Qt-x11的qvfb工具仿真调试。下面以demo程序为例,确保qmake来自/usr/local/Trolltech/QtEmbedded-4.5.1/bin：
# qmake -project
# qmake
# make
# qvfb &
# ./demo -qws

我已经按楼上的一步步地做了
在编译 demos 出现了以下错误：
好慢啊，今天花了一个下午把Qt -embedded 编译好了
在编译demos 时发现错误：
