#make install-strip //生成瘦身应用程序和库
编译qt-x11-opensource-src-4.5.1-arm
进入/usr/local/qt/qt-x11-opensource-src-4.5.1-arm目录，进行编译安装。在终端中进行如下操作：
＃./configure "
-release "
-shared "
-fast "
-no-largefile "
-qt-sql-sqlite "
-no-qt3support "
-no-xmlpatterns "
-no-mmx "
-no-3dnow "
-no-sse "
-no-sse2 "
-no-svg "
-no-webkit "
-qt-zlib "
-qt-gif "
-qt-libtiff "
-qt-libpng "
-qt-libmng "
-qt-libjpeg "
-make libs "
-nomake tools "
-nomake examples "
-nomake docs "
-nomake demo "
-no-nis "
-no-cups "
-no-iconv "
-no-dbus "
-no-openssl "
-xplatform qws/linux-arm-g++ "
-embedded arm "
-little-endian "
-qt-freetype "
-depths 16,18 "
-qt-gfx-linuxfb "
-no-gfx-transformed "
-no-gfx-multiscreen "
-no-gfx-vnc "
-no-gfx-qvfb "
-qt-kbd-usb "
-no-glib "
-qt-mouse-tslib -I/home/cnnbboy/opt/include -L/home/cnnbboy/opt/lib
之所以裁剪那么多参数，是因为开发版空间有限，只要完成我所需要的功能就可以了,之后配置环境变量，我的配置如下：
export QTDIR=/qq2440
export T_ROOT=/tslib
export PATH=$QTDIR/bin:$PATH
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_PLUGINDIR=$T_ROOT/lib/ts
export TSLIB_CONFFILE=$T_ROOT/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export QWS_MOUSE_PROTO=tslib:/dev/input/event0
export LD_LIBRARY_PATH=$T_ROOT/lib:$QTDIR/lib
最后，运行qt的测试程序成功，移植OK了。
出现的问题：
运行测试程序中说缺少librt.so.1 ，libstdc++.so.6 ，libgcc_s.so.1这三个文件，这是因为交叉编译的环境不同，从主机上的拷贝过去即可。还提示找不到字体，是因为编译时没有设定安装目录，在板子上建立一个连接就可以了。
