在ubuntu14.04 LTS上的交叉编译工具链该怎样去实现呢

PC系统：ubuntu14.04 LTS
交叉编译工具链：gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu
step1：

在opencv源代码目录创建文件夹：build，用于存放编译中间文件。
step2：

打开命令控制台，输入cmake-gui运行
step3:

配置源文件路径和编译中间文件路径：

step4:


step5:

C编译器：/usr/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc
C++编译器：/usr/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++
头文件：/usr/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/aarch64-linux-gnu/libc/usr/include

step6:


step7:

取消选项：with-cuda，with-opencl

step8

更改安装目录：

step9

generate:

step10

打开命令控制台进入build目录，执行make -j4进行编译，当然会产生错误，后面根据错误具体再修改。

解决办法：
修改编译目录build下面的CMakeCache.txt文件，如下所示两个地方添加 -fPIC 选项。


CMAKE_CXX_FLAGS:STRING=-fPIC
CMAKE_C_FLAGS:STRING=-fPIC


step10
再次编译，继续出错。

进入Eigen3库目录发现缺少unsupported目录，下载新的Eigen库并替换，因为Eigen库全部都是头文件，所以直接替换就好，不依赖具体的平台。

step13

再次编译，编译成功。
step14

执行 make install 进行安装，安装完成后，可以将Install目录下的内容拷贝到RK3326板子上/usr目录下相关的目录中即可。
