        安装opencv问题详解
        我使用的是redhat 9.0，先安装了海思3515官方配套的SDK，gcc版本为3.4.3。在redhat下使用的是cmake3.1.1，是直接用已经编译好的程序，包含cmake-gui。鄙人私下认为，Linux系统版本和cmake的版本对于opencv的安装应该是没有什么影响的。不过，不同的安装环境的确会导致在安装过程中出现各种不同类型的错误。下图是安装好的arm-gcc相关编译工具。

安装步骤：
①配置cmake
选择源码文件夹（解压源码所得的文件夹），选择编译目录（自己建立一个目录），选择编译器和头文件目录。

如下图，operation stystem和version processor随便写，编译器分别选择gcc和g++，targetroot选择arm-linux编译器的头文件目录，我这里是
/opt/hisi-linux/x86-arm/gcc-3.4.3-uClibc-0.9.28/usr/include/。点击finish完成。

然后，华丽丽地报错了。

查看错误提示，提到了CUDA，后来查了下，arm-linux没有相关的库。在列表中取消所有与CUBA相关的项，重新点击configure。没有报错了。

由于arm-linux有很多库是没有的，所以在配置这一步还要取消很多的选项。具体配置如下：


再点击Generate，生成makefiles。然后，进入build目录，开始make。出错，提示：
/opt/hisi-linux/x86-arm/gcc-3.4.3-uClibc-0.9.28/bin/../../gcc-3.4.3-uClibc-0.9.28//usr/include/stdlib.h:691: error: syntax error before '*' token

make[1]: ***
[3rdparty/zlib/CMakeFiles/zlib.dir/all] Error 2
make: *** [all] Error 2

解决办法：打开stdlib.h文件，将684行和706行的#ifdef….   #endif注释取消。

继续make，然后出错。提示：

解决办法：进入operations.hpp，将4021行的那个函数注释掉。

继续make，然后又有新错误出现了。

解决办法：wchar.h文件其实在usr/include/bits目录下，故打开persistence.cpp文件，在48行处，将#include改为#include，错误减少了，但没有解决。还是会提示wcstombs函数没有定义。该函数包含在stdlib.h里，进入该头文件，将684行和706行的#ifdef和#endif注释掉，错误解决。

继续make，然后继续出错提示：

make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2

解决办法：直接将893行到908行的条件编译代码注释掉，问题解决。

继续make，然后出错。提示：

解决办法：test文件编译出错，进入cmake-gui，取消ts模块的勾选。该模块是用于测试的，可以不用勾选。重新configure和generation。错误解决。

继续make，然后出错，提示：
/root/opencv/opencv-2.4.9/modules/legacy/src/pyrsegmentation.cpp: In function `CvStatus icvPyrSegmentation8uC3R(uchar*, int, uchar*, int, CvSize, int, CvSeq**, CvMemStorage*, int, int, int)':

make[1]: *** [modules/legacy/CMakeFiles/opencv_legacy.dir/all] Error 2

解决办法：进入pyrsegmentation.cpp，将CvStatus icvPyrSegmentation8uC3R函数里的代码清空，直接在函数里填上”return CV_OK;”，问题解决。

继续make，然后终于完成了。输入命令make install，完成安装。终于完成了，看到这一路遇到这么多错误，我也是醉了。

最后申明一下：由于本人也是新手上路，上述的解决办法仅供参考。这些解决办法，一部分来源百度，一部分来源于自己尝试探索还有一部分来自于本论坛的9crk大神的指导。欢迎大家补充各类错误及解决办法，欢迎拍砖。
