编译 qt-everywhere-opensource-src-4.6.2.tar

编译 qt-everywhere-opensource-src-4.6.2.tar

for 嵌入式　arm版本

$export CPLUS_INCLUDE_PATH=/home/dengroj/arm_china_tools/arm-none-linux-gnueabi/include/c++/4.4.1:/home/dengroj/arm_china_tools/arm-none-linux-gnueabi/include/c++/4.4.1/arm-none-linux-gnueabi


修改qt-everywhere-opensource-src-4.6.2/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
这一步必须有，不然肯定出错。

出现这个问题。

原因是交叉编译器版本问题。我用的是4.4.1，按它的4.1.2来弄吧。
