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?解决方案 https://www.cnblogs.com/bing-yu12/p/6367894.html
https://blog.csdn.net/u011596455/article/details/60322568
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
编译工具命令行相关，路径等 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
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 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

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
./configure --host=arm-linux-gnueabihf --prefix=$OPENCV_DEPEND --enable-shared --enable-static
make
make installexport LDFLAGS="/home/osrc/Desktop/document/arm/opencv-depend/lib"（此处有误导致一直不通，应该在前面加一个-L）
export CPPFLAGS="/home/osrc/Desktop/document/arm/opencv-depend/include"
正确方法如下：
./configure --host=arm-linux-gnueabihf --prefix=$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。

457 make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
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-guicmake-gui
然后设置相应的目录，
- 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
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':

modules/core/CMakeFiles/pch_Generate_opencv_core.dir/build.make:62: recipe for target 'modules/core/precomp.hpp.gch/opencv_core_Release.gch' failed
make[2]: *** [modules/core/precomp.hpp.gch/opencv_core_Release.gch] Error 1
CMakeFiles/Makefile2:1102: recipe for target 'modules/core/CMakeFiles/pch_Generate_opencv_core.dir/all' failed
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'

892 history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

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

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/pkgconfigexport PKG_CONFIG_PATH
如图
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 test6.1 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
/mnt/workspace/Xilinx/SDK/2017.4/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabihf/6.2.1/../../../../arm-linux-gnueabihf/bin/ld: warning: libz.so.1, needed by /home/osrc/Desktop/document/arm/opencv-install/lib/libopencv_core.so, not found (try using -rpath or -rpath-link)

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/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
在运行时，还要把arm/opencv-install/lib目录下的所有.so文件都拷贝到arm的/usr/lib或者/lib目录下。
