# 定义变量，并export使之对后面的进程可见
export PATH=/usr/local/arm/arm-2009q3/bin:$PATH
export TOOLCHAIN=/usr/local/arm/arm-2009q3
export TB_CC_PREFIX=arm-linux-
export PKG_CONFIG_PREFIX=$TOOLCHAIN/arm-none-linux-gnueabi

# 删除文件夹
rm -fr qt-everywhere-opensource-src-4.7.1
rm -fr /opt/qt-4.7.1

# 打包压缩
tar xfvz qt-everywhere-opensource-src-4.7.1.tar.gz

# 切换当前目录
cd qt-everywhere-opensource-src-4.7.1

# 执行configure命令，遇到问答的时候选择yes
echo yes 
[解决办法]
 ./configure -opensource -embedded arm -xplatform qws/linux-arm-g++  -no-webkit -qt-libtiff -qt-libmng  -qt-mouse-tslib -qt-mouse-pc -no-mouse-linuxtp -prefix /opt/qt-4.7.1   -I /usr/local/tslib/include -L /usr/local/tslib/lib

# 执行 make 命令，标准输出和标准错误显示到屏幕的同时写入文件../qte4.7.1Makelog，然后执行 make install 命令
make 2>&1 
[解决办法]
 tee ../qte4.7.1Makelog && make install
