arm-linux qt交叉编译,qt 交叉编译
tslib-1.4编译通过，安装到/usr/local/下，同时复制了一份到/nand1/tslib-1.4中
进入/home/Raymond/qt-embedded-arm-tslib中
执行：./configure -prefix /nand1/Trolltech/QtEmbeddedARMTSLib -release -shared -qvfb -make libs -nomake tools -make examples -make docs -make demo -no-cups -no-iconv -no-dbus -webkit -no-openssl -xplatform qws/linux-arm-g++ -embedded arm -little-endian -qt-freetype -qt-gfx-linuxfb -no-gfx-transformed -no-gfx-multiscreen -no-gfx-vnc -no-gfx-qvfb -qt-kbd-tty -qt-kbd-usb -no-glib -qt-mouse-tslib -I/nand1/tslib-1.4/include -L/nand1/tslib-1.4/lib
其中我已经指定了头文件目录和库文件目录
但是在configure过程中，出现如下错误：
The tslib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR and QMAKE_LIBDIR in
/home/Raymond/qt-embedded-arm-tslib/mkspecs/qws/linux-arm-g++.
请问这个是什么原因？
根据提示，我又将
/home/Raymond/qt-embedded-arm-tslib/mkspecs/qws/linux-arm-g++ /qmake.conf
中添加了QMAKE_INCDIR=/nand1/tslib-1.4/include
QMAKE_LIBDIR=/nand1/tslib-1.4/lib
这两个参数原本在文件中没有，自己编写
回到/home/Raymond/qt-embedded-arm-tslib中
继续我的configure
可是结果还是 The tslib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR and QMAKE_LIBDIR in
/home/Raymond/qt-embedded-arm-tslib/mkspecs/qws/linux-arm-g++.
请问这是为什么啊，我晕了，谢谢各位朋友帮忙指点
解决办法：
是arm-linux-gcc的路径没有添加到系统变量中。。。
吸取教训 在Shell中输入EXPORT PATH = ....:$PATH 语句时，只在该Shell中可用。
只有
1.修改profile文件：
#vi /etc/profile
在里面加入:
export PATH="$PATH:/opt/au1200_rm/build_tools/bin"
2.修改.bashrc文件：
# vi /root/.bashrc
在里面加入：
export PATH="$PATH:/opt/au1200_rm/build_tools/bin"
才能完成添加
如果经过上述操作后问题仍然无法解决，则换成tslib-1.4重新编译并安装，安装后重新编译qt，问题就得以解决！
如果出错：

解决办法：
修改qt-everywhere-opensource-src-4.6.0/mkspecs/qws/linux-arm-g++/qmake.conf 文件(添加lts参数)：
QMAKE_CC = arm-linux-gcc -lts
QMAKE_CXX = arm-linux-g++ -lts
QMAKE_LINK = arm-linux-g++ -lts
QMAKE_LINK_SHLIB = arm-linux-g++ -lts
