**交叉编译：** [https://baike.baidu.com/item/%E4%BA%A4%E5%8F%89%E7%BC%96%E8%AF%91/10916911?fr=aladdin][https_baike.baidu.com_item_E4_BA_A4_E5_8F_89_E7_BC_96_E8_AF_91_10916911_fr_aladdin]

交叉编译openCV，步骤繁琐，依赖项多，变种复杂。并且我们的xilinx SDK的交叉编译工具可能与其他arm-linux工具不同，加之是在虚拟机上交叉编译，进一步增大了难度。所以需要广泛参考，每步详细记载，并且要有耐心。流程较长，务必不要出错。

我们的编译过程比其他博客出了更多的bug，非常难以解决，基本上每步都会遇到相应的bug，好在最后问题得到了解决。

# 一、安装依赖项 #

若不装依赖项，后续make时候会出现下面报错：

FFMPEG:                        NO
           --      codec:                 NO
           --      format:                NO
           --      util:                  NO
           --      swscale:               NO
           --      gentoo-style:          NO

安装依赖项命令行：

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev

但是出现了报错

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
    E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

完成安装。

# 二、安装编译器 #

## 2.1 编译器安装与路径 ##

编译器已被装好，

编译器相关：[https://www.cnblogs.com/deng-tao/p/6432578.html][https_www.cnblogs.com_deng-tao_p_6432578.html]

[编译工具命令行相关，路径等 https://blog.csdn.net/weixin\_36474809/article/details/83342549][https_blog.csdn.net_weixin_36474809_article_details_83342549]

/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin
    arm-linux-gnueabihf-g++
    gcc version 6.2.1 20161114 (Linaro GCC Snapshot 6.2-2016.11)

## 2.2 环境变量配置 ##

环境变量配置之前我们需要确定相应的安装路径，注意，**已经安装好的与以后安装的路径，一定要与这三个路径一致，以后所有涉及路径的操作，必须与你的路径一致。**

在  /root/.bashrc 添加环境变量

export PATH=$PATH:/mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin      arm编译器路径

export OPENCV\_DEPEND=/home/osrc/Desktop/document/arm/opencv-depend      opencv依赖库安装路径

export OPENCV\_INSTALL=/home/osrc/Desktop/document/arm/opencv-install       opencv安装路径

export ARCH=arm  
export CROSS\_COMPILE=arm-xilinx-linux-gnueabihf-

gedit /root/.bashrc

在`/root/.bashrc`最下方添加环境变量：

export PATH=$PATH:/mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin
    export OPENCV_DEPEND=/home/osrc/Desktop/document/arm/opencv-depend
    export OPENCV_INSTALL=/home/osrc/Desktop/document/arm/opencv-install
    export ARCH=arm
    export CROSS_COMPILE=arm-xilinx-linux-gnueabihf-

此时输入指令或重启电脑，使新的环境变量生效。输入指令如下：

source /root/.bashrc

检验环境变量生效的方法是：在root权限下，终端中输入arm，然后按Tab键，出现下面这些，表示环境变量添加成功：

root@osrc-virtual-machine:/# arm
    arm2hpdl                        arm-linux-gnueabihf-gcov
    arm-linux-gnueabihf-addr2line   arm-linux-gnueabihf-gcov-tool
    arm-linux-gnueabihf-ar          arm-linux-gnueabihf-gdb
    arm-linux-gnueabihf-as          arm-linux-gnueabihf-gprof
    arm-linux-gnueabihf-c++         arm-linux-gnueabihf-ld
    arm-linux-gnueabihf-c++filt     arm-linux-gnueabihf-ld.bfd
    arm-linux-gnueabihf-cpp         arm-linux-gnueabihf-nm
    arm-linux-gnueabihf-elfedit     arm-linux-gnueabihf-objcopy
    arm-linux-gnueabihf-g++         arm-linux-gnueabihf-objdump
    arm-linux-gnueabihf-gcc         arm-linux-gnueabihf-ranlib
    arm-linux-gnueabihf-gcc-6.2.1   arm-linux-gnueabihf-readelf
    arm-linux-gnueabihf-gcc-ar      arm-linux-gnueabihf-size
    arm-linux-gnueabihf-gcc-nm      arm-linux-gnueabihf-strings
    arm-linux-gnueabihf-gcc-ranlib  arm-linux-gnueabihf-strip

# 三、安装依赖库 #

## 3.1 下载依赖库 ##

OpenCV交叉编译之前，**首先需要对依赖库进行交叉编译**。因为OpenCV依赖于很多库函数，如果在编译OpenCV之前没有编译依赖项，就会导致编译后的OpenCV无法使用。  
OpenCV交叉编译时各个库的依赖关系如下所示：

OpenCV
        zlib
        jpeg
        libpng
            zlib
        tiff
            zlib
        ffmpeg
            x264
            xvidcore

下载依赖库：

**注：**再次，再次感谢下文博主，将相应安装包放在百度云盘上，为我节省了大量操作。 [https://blog.csdn.net/ajianyingxiaoqinghan/article/details/70194392][https_blog.csdn.net_ajianyingxiaoqinghan_article_details_70194392_]  
**1、本文所有操作都需要以root权限进行操作。**  
**2、已有博主将其全部打包分享在百度云，百度云下载地址如下。**  
链接: [https://pan.baidu.com/s/1D40Jq0u1uAbL0mpuPV9\_hQ][https_pan.baidu.com_s_1D40Jq0u1uAbL0mpuPV9_hQ] 密码: idju

下载到的依赖库如下：

*  zlib-1.2.11
 *  jpegsrc.v9b
 *  libpng-1.6.29
 *  yasm-1.3.0
 *  x264-snapshot-20170415-2245
 *  xvidcore\_1.3.3.orig
 *  ffmpeg-2.8.11

## 3.2 交叉编译依赖库 ##

将依赖库下载到相应文件夹，解压。

后面所有的交叉编译操作，都需要进入依赖库解压的地址进行操作。

### zlib的交叉编译为例： ###

./configure --prefix=$OPENCV_DEPEND

注意，运行此步之后必须再次修改makefile，按顺序运行

将makefile之中，改为相应的与我们的编译器一致的指令,此处注意两点，

*  一是要用root来执行相应的make操作
 *  g++行不通，编译时会有error报错，要用gcc

CC=arm-linux-gnueabihf-gcc
    AR=arm-linux-gnueabihf-ar
    RANLIB=arm-linux-gnueabihf-ranlib
    LDSHARED=arm-linux-gnueabihf-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map

然后进行make，make install

root@osrc-virtual-machine:/home/osrc/Desktop/document/arm/opencv-depend/Cross-Compile Packages/zlib-1.2.11# make

    rm -f /include/zlib.h /include/zconf.h
    cp zlib.h zconf.h /include
    chmod 644 /include/zlib.h /include/zconf.h

做完之后文件夹会多出几个目录：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjQ3NDgwOQ_size_27_color_FFFFFF_t_70][]

### 流程 ###

解压，进入解压文件夹

./configure --prefix=$OPENCV_DEPEND

来确定安装的目录

然后更改makefile的编译器gedit Makefile

CC=arm-linux-gnueabihf-gcc
    AR=arm-linux-gnueabihf-ar
    RANLIB=arm-linux-gnueabihf-ranlib
    LDSHARED=arm-linux-gnueabihf-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map

最后make， make install

剩下几个库按照流程如法炮制

### libjpeg的交叉编译 ###

解压jpegsrc.v9b.tar.gz，进入文件夹

注意我们与原版博客的不同，我们的编译工具arm-linux-gnueabihf系列，不是原版的arm-linux

./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --prefix=$OPENCV_DEPEND --enable-shared --enable-static
    更改make文档（其实不用改，上面在config已经更改，点进去make文档会发现已经被更改过）
    make
    make install

运行成功标志：opencv-depend之中include文件夹多了jpeglib.h

### libpng的交叉编译 ###

解压libpng-1.6.29，进入文件夹

（此库交叉编译多次，此库依赖zlib库，所以必须想办法将zlib库交叉编译。一直以来的错误是此库无法找到zlib库。发现错误在于zlib之前的LDFLAGS之前需要加-L字符）

377  sh cmake_arm_gnueabi_softfp.sh
      378  cd ..
      379  ls
      380  rm -r build_linux_arm_softfp
      381  pwd
      382  cd 
      383  cd ..
      384  su
      385  ./configure --host=arm-linux-gnueabihf --prefix=$OPENCV_DEPEND --enable-shared
      386  $OPENCV_DEPEND
      387  echo $OPENCV_DEPEND
      388  ls $OPENCV_DEPEND
      389  ./configure --host=arm-linux-gnueabihf --prefix=$OPENCV_DEPEND --enable-shared
      390  echo $OPENCV_DEPEND
      391  pwd
      392  ./configure --host=arm-linux-gnueabihf --prefix=$OPENCV_DEPEND --enable-shared LDFLAGS=-L/home/osrc/Desktop/document/arm/opencv-depend/lib

下面为尝试过的（错误写法）：

export LIBS=/home/osrc/Desktop/document/arm/opencv-depend/lib CPPFLAGS=/home/osrc/Desktop/document/arm/opencv-depend/include

./configure --host=arm-linux-gnueabihf --prefix=$OPENCV\_DEPEND LIBS=/home/osrc/Desktop/document/arm/opencv-depend/lib CPPFLAGS=/home/osrc/Desktop/document/arm/opencv-depend/include --enable-shared --enable-static

./configure --host=arm-linux-gnueabihf --prefix=$OPENCV\_DEPEND CC=arm-linux-gnueabihf-gcc

但是会提示找不到zlib的路径，因此我们采用此方法：[https://blog.csdn.net/youcijibi/article/details/76427725][https_blog.csdn.net_youcijibi_article_details_76427725]

./configure --host=arm-linux-gnueabihf --prefix=$OPENCV_DEPEND --enable-shared --enable-static
    make
    make install

export LDFLAGS="/home/osrc/Desktop/document/arm/opencv-depend/lib"（此处有误导致一直不通，应该在前面加一个-L）

export CPPFLAGS="/home/osrc/Desktop/document/arm/opencv-depend/include"

正确方法如下：

./configure --host=arm-linux-gnueabihf --prefix=$OPENCV\_DEPEND --enable-shared LDFLAGS=-L/home/osrc/Desktop/document/arm/opencv-depend/lib

然后make，make install

### yasm的交叉编译 ###

解压，进入文件夹

CC=arm-linux-gnueabihf-gcc ./configure --enable-shared --host=arm-linux-gnueabihf --disable-asm --prefix=$OPENCV_DEPEND
    make
    make install

运行成功标志：opencv-depend之中include文件夹多了一个libyasm文件夹

### libx264的交叉编译 ###

解压last\_x264.tar.bz2并进入文件夹

CC=arm-linux-gnueabihf-gcc ./configure --enable-shared --host=arm-linux-gnueabihf --disable-asm --prefix=$OPENCV_DEPEND
    make
    make install

运行成功标志：opencv-depend之中include文件夹多了一个x264\_config.h文件

### libxvid的交叉编译 ###

解压文件xvidcore\_1.3.3.orig.tar.gz，并进入文件夹及其子目录（注意此处与之前不同）

cd build/generic

./configure --prefix=$OPENCV_DEPEND --host=arm-linux-gnueabihf --disable-assembly
    make
    make install

运行成功标志：opencv-depend之中include文件夹多了一个xvid.h文件

### ffmpeg的交叉编译 ###

解压ffmpeg-2.8.11.tar.gz，并进入文件夹（注意，需要为2.8版本，不要下载新的3.3版本！否则会编译出错）

./configure --prefix=$OPENCV\_DEPEND --enable-shared --disable-static --enable-gpl --enable-cross-compile --arch=arm --disable-stripping --target-os=linux --enable-libx264 --enable-libxvid --cc=arm-linux-gnueabihf-gcc --enable-swscale --extra-ldflags=-L$OPENCV\_DEPEND/lib --extra-cflags=-I$OPENCV\_DEPEND/include

然后make ，make install

此程序make时间较长。

运行成功后lib文件夹多出av系列函数。

至此，依赖库交叉编译完成。

## 3.3 OpenCV依赖库复制到ARM编译器路径下 ##

需要将前面路径下的lib和include中所有文件分别拷贝到后面路径下的lib和include下。注意此处要按照我们的目录来修改。

/home/osrc/Desktop/document/arm/opencv-depend
    /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi
    /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/arm-linux-gnueabihf

命令行如下：

cp -r /home/osrc/Desktop/document/arm/opencv-depend/include/ /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/
    cp -r /home/osrc/Desktop/document/arm/opencv-depend/lib/ /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/

为保险起见，我们将子文件夹中的hf文件夹也多拷一份

cp -r /home/osrc/Desktop/document/arm/opencv-depend/include/ /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/arm-linux-gnueabihf
    cp -r /home/osrc/Desktop/document/arm/opencv-depend/lib/ /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/arm-linux-gnueabihf

即使进行了拷贝，但后面仍然有编译器找不到相应的lib的情况，再此后还会出相应的bug。因此，我们可能在后面需要指定相应的地方更改，在arm/openCV-2.4.9/arm-build/modules/highgui/CMakeFiles/opencv-highgui.dir之中更改，这个后面会谈。

# 四、OpenCV的交叉编译 #

## 4.1 获取OpenCV源码 ##

这里使用的是OpenCV 2.4.9版本，可以在官网上下载。  
官网下载地址：http://opencv.org/releases.html

注：不带交叉编译，而是直接编译的openCV见此：[https://blog.csdn.net/weixin\_36474809/article/details/83373908][https_blog.csdn.net_weixin_36474809_article_details_83373908]

## 4.2 设置工具链toolchain.cmake ##

下载并解压OpenCV后，进入OpenCV 2.4.9的路径，并新建文件夹arm-build（与之前的build区分）：工程要在此文件夹下进行。

在arm-build文件夹中，用vim或gedit新建文件`toolchain.cmake`：

gedit toolchain.cmake

在里面添加下面内容：（路径内容要与自己的一致，编译工具链要与自己的一致）

###########user defined############# 
    set( CMAKE_SYSTEM_NAME Linux ) 
    set( CMAKE_SYSTEM_PROCESSOR arm ) 
    set( CMAKE_C_COMPILER arm-linux-gnueabihf-gcc ) 
    set( CMAKE_CXX_COMPILER arm-linux-gnueabihf-g++ ) 
    ###########user defined############# 
    set( CMAKE_FIND_ROOT_PATH "/home/osrc/Desktop/document/arm/opencv-depend/" ) 
    set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER ) 
    set( CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) 
    set( CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) 
    ######################################

运行下面内容

cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake ../

## 4.3 配置openCV的cmake ##

安装并运行cmake的gui（下文中路径好像有误，应该在arm-build之中运行）

root@osrc-virtual-machine:/home/osrc/Desktop/document/opencv-2.4.9/build# cmake-gui
    The program 'cmake-gui' is currently not installed. You can install it by typing:
    apt install cmake-qt-gui
    root@osrc-virtual-machine:/home/osrc/Desktop/document/opencv-2.4.9/build# apt install cmake-qt-gui

cmake-gui

然后设置相应的目录，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjQ3NDgwOQ_size_27_color_FFFFFF_t_70 1][]

*  source code:      /home/osrc/Desktop/document/arm/opencv-2.4.9
 *  build binaries:    /home/osrc/Desktop/document/arm/opencv-2.4.9/arm-build
 *  CMAKE\_INSTALL\_PREFIX（安装目录），默认为/opencv-2.4.9/build/install，改为我们之前设置的安装目录：/home/osrc/Desktop/document/arm/opencv-install
 *   去掉 WITH\_CUDA
 *  去掉 WITH\_GTK
 *  去掉 WITH\_1394
 *  去掉 WITH\_GSTREAMER
 *  去掉 WITH\_LIBV4L
 *  去掉 WITH\_TIFF
 *  去掉 BUILD\_OPENEXR
 *  去掉 WITH\_OPENEXR
 *  去掉 BUILD\_opencv\_ocl
 *  去掉 WITH\_OPENCL（注意区分OPENGL与OPENCL的区别）
 *  去掉 WITH MMPEG

做好相应更改之后，把config与generate

我们的项目并不需要mmpeg的库，并且在后面的交叉编译之中mmpeg库总是出现错误，因此我们去掉WITH MMPEG。

## 4.4 修改cmakeCache.txt ##

此时修改在`/opencv-2.4.9/arm-build`文件夹中的`CMakeCache.txt`：  
CMAKE\_EXE\_LINKER\_FLAGS选项本来为空，此时在后面加上：`-lpthread -lrt`

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjQ3NDgwOQ_size_16_color_FFFFFF_t_70][]

## 4.5 交叉编译 ##

在路径arm-build路径下，进行 make 与make install

### 出错一、libpng ###

[  5%] Generating precomp.hpp
    [  5%] Generating precomp.hpp.gch/opencv_core_Release.gch
    /mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin/../arm-linux-gnueabihf/libc/usr/lib/crt1.o: In function `_start':
    init.c:(.text+0x34): undefined reference to `main'

    make[1]: *** [modules/core/CMakeFiles/pch_Generate_opencv_core.dir/all] Error 2
    Makefile:149: recipe for target 'all' failed
    make: *** [all] Error 2

后续发现如此低级错误可能是少编译了libpng的库。也说明流程较长时候必须要有足够的耐心，并且要及时检验。

后续libpng依然出错，config时显示找不到zlib，在config之中加LDFLAGS即可，见上面libpng的编译。

### 出错二、gnu/stubs-32.h ###

[11%] Building CXX object modules/highgui/CMakeFiles/opencv_highgui_pch_dephelp.dir/opencv_highgui_pch_dephelp.cxx.o
    cc1plus: warning: include location "/usr/include/x86_64-linux-gnu" is unsafe for cross-compilation [-Wpoison-system-directories]
    。。。
    /usr/include/x86_64-linux-gnu/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory

解决方法：  sudo apt-get install g++-multilib

之后再make，编译器很快接上面%11继续。

### 出错三、unknow register name 'st' in 'asm' ###

此步出错在于编译器找不到相应的文件，所以我们需要在相应的CMakeFiles之中添加下面的东西。位置 arm/opencv-2.4.9/arm-build/modules/highgui/CMakeFiles/opencv-highgui.dir,，这个文件制定了相应的路径。我们在后面添加依赖路径，注意语法，前后冒号。

另外，必须把另一个core的时候也出现此问题，因此，也需要把core的后面加相应的dir加路径。

/arm/opencv-2.4.9/arm-build/modules/core/CMakeFiles/opencv\_perf\_core.dir

解决了这些bug之后，终于编译完成

make install

## 4.6 隐患 ##

*  mmpeg可能没用到，没有编译
 *  aarch的设置

# 五、移植到ARM上 #

## 5.1 配置pkg-config ##

参考：[https://blog.csdn.net/luotuo44/article/details/24836901][https_blog.csdn.net_luotuo44_article_details_24836901]

用第三方库，就少不了要使用到第三方的头文件和库文件。我们在编译、链接的时候，必须要指定这些头文件和库文件的位置。  
对于一个比较大第三方库，其头文件和库文件的数量是比较多的。如果我们一个个手动地写，那将是相当麻烦的。所以，pkg-config就应运而生了。pkg-config能够把这些头文件和库文件的位置指出来，给编译器使用。  
平常都是这样用pkg-config的：

gcc main.c `pkg-config --cflags --libs gtk+-2.0` -o main

此为把gtk的头文件路径和库文件列出来，让编译去获取。–cflags和–libs分别指定头文件和库文件。

在前面的OpenCV配置过程中，pkg-config便已经生成。生成地址为`/usr/local/arm/opencv-install/lib/pkgconfig/opencv.pc`

（注意，make install之后才有此步）

## 5.2 配置shell ##

gedit /etc/bash.bashrc

在最后一行加入：注意路径要与自己的一致。  
`PKG_CONFIG_PATH=$PKG_CONFIG_PATH:`/home/osrc/Desktop/document/arm/opencv-install/lib/pkgconfig  
`export PKG_CONFIG_PATH`

如图

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjQ3NDgwOQ_size_16_color_FFFFFF_t_70 3][]

然后 source /etc/bash.bashrc

# 六、测试 #

创建并编辑test.cpp文件

#include <cv.h>
    #include <highgui.h>
    #include <iostream>
    using namespace std;
    
    int main(int argc, char *argv[])
    {
        IplImage* image = cvLoadImage("/root/Desktop/miska.jpg");
        if(image == NULL)
        {
            cout<<"loud image fail"<<endl;
        return -1;
        }
        cvNamedWindow("src", 1);
        cvShowImage("src", image);
        cvWaitKey();
        cvDestroyWindow("src");
        cvReleaseImage(&image);
    
        return 0;
    }

保存并退出之后，输入如下：

arm-linux-gnueabihf-g++ `pkg-config --cflags --libs opencv` test.cpp -lpthread -lrt -o test

## 6.1 bug 找不到头文件 ##

root@osrc-virtual-machine:/home/osrc/Desktop/document/test-opencv# arm-linux-gnueabihf-g++ `pkg-config --cflags --libs opencv` test.cpp -lpthread -lrt -o test
    In file included from test.cpp:1:0:
    /home/osrc/Desktop/document/arm/opencv-install/include/opencv/cv.h:67:38: fatal error: opencv2/video/tracking.hpp: No such file or directory
     #include "opencv2/video/tracking.hpp"
                                          ^
    compilation terminated.

显示没有相应的文件，我们在modules中把相应的文件夹拷贝到opencv install之中，然后将include之中同名的文件拷出来。

/home/osrc/Desktop/document/arm/opencv-install/include/opencv/cv.h:72:37: fatal error: opencv2/legacy/compat.hpp: No such file or directory
     #include "opencv2/legacy/compat.hpp"

一次video文件夹，一次legency文件夹。

然后编译，解决了相应的找不到头文件的问题。

## 6.2 bug找不到编译库 ##

找不到zlib，找不到libjpeg，找不到libpng，   warning: libz.so.1, needed by。。。

**尝试解决方法一、**将相应的opencv-depend库里面的内容搬到opencv-install里面。

cp -r /home/osrc/Desktop/document/arm/opencv-depend/include/ /home/osrc/Desktop/document/arm/opencv-install/  
cp -r /home/osrc/Desktop/document/arm/opencv-depend/lib/ /home/osrc/Desktop/document/arm/opencv-install/

运行之后并不成功。

**尝试解决方法二、编译时加入** \-Wl,-rpath,/home/osrc/Desktop/document/arm/opencv-depend/lib/:/home/osrc/Desktop/document/arm/opencv-depend/lib/:

[https://www.cnblogs.com/candl/p/7358384.html][https_www.cnblogs.com_candl_p_7358384.html]

[https://www.cnblogs.com/homejim/p/8004883.html][https_www.cnblogs.com_homejim_p_8004883.html]

命令行：

arm-linux-gnueabihf-g++ \`pkg-config --cflags --libs opencv\` test.cpp -lpthread -lrt -o test -Wl,-rpath,/home/osrc/Desktop/document/arm/opencv-depend/lib/:/home/osrc/Desktop/document/arm/opencv-install/lib/:

终于运行成功，生成test文件。非常繁琐的步骤，中间出现了无数的bug，好在终于完成了运行。

## 6.3 ARM板运行 ##
