在VS2010下编译通过的程序，移植到ARM平台时
通过ARM-GCC交叉编译时出现-fpermissive问题，问题描述是taking address of temporary [-fpermissive]
查了一些资料，可能是不同编译器或者新旧编译器对于c++标准的不同解释的结果
在GCC下对于模板继承的规定与VS不同
有一个简单粗暴的解决办法，就是在交叉编译指令里面加入-fpermissive这一条命令，让模板代码由出错降为警告，从而编译通过
例如刚开始时我的指令为
arm-xilinx-linux-gnueabi-g++ -I/home/zed/opencv/opencv-2.4.8/install/include/opencv -I/home/zed/opencv/opencv-2.4.8/install/include/opencv2 -I/home/zed/opencv/opencv-2.4.8/install/include -L/home/zed/opencv/opencv-2.4.8/install/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann -lopencv_gpu -lopencv_nonfree -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_videostab -lstdc++ -o xuanzhuan1 ./xuanzhuan.c
编译出错，改为arm-xilinx-linux-gnueabi-g++ -I/home/zed/opencv/opencv-2.4.8/install/include/opencv -I/home/zed/opencv/opencv-2.4.8/install/include/opencv2 -I/home/zed/opencv/opencv-2.4.8/install/include -L/home/zed/opencv/opencv-2.4.8/install/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann -lopencv_gpu -lopencv_nonfree -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_videostab -lstdc++ -fpermissive -o xuanzhuan1 ./xuanzhuan.c 虽然会有警告，但是可以编译通过
