opencv 编译安装

解压缩后，
进去到 opencv-4.1.0 目录下，
创建 build 文件夹，
根据需要配置编译选项如下：

export PKG_CONFIG_PATH=/home/nsc/workspace/himix200_ffmpeg_install/lib/pkgconfig:$PKG_CONFIG_PATH

注意：最后有两个点，表示执行上级目录中的 CMakeLists.txt 文件！

说明：
CMAKE_BUILD_TYPE ：指定基于 make 的产生器的构建类型(Debug, Release)
CMAKE_INSTALL_PREFIX ：安装路径的前缀
CMAKE_C_COMPILER ：指定 C 编译器
CMAKE_CXX_COMPILER ：指定 C++ 编译器
BUILD_SHARED_LIBS ：ON - 创建动态库，OFF - 创建静态库
CMAKE_C_FLAGS ：设置编译 C 文件时的选项，Linux下编译动态库时，必须加上 -fPIC 参数，否则在链接时会有错误提示
CMAKE_CXX_FLAGS ：设置编译 C++ 文件时的选项
CMAKE_EXE_LINKER_FLAGS ：设定链接选项

$ make
$ make install

3.常见问题：

问题一：
libpng/pngstruct.h:30:18: fatal error: zlib.h: No such file or directory

方法一：

$ sudo apt-get install zlib1g-dev

重新编译

方法二：(推荐)

这个版本的OpenCV已经包含了 zlib 第三方的库！

在 CMakeLists.txt 文件中查找 OPENCV_CONFIG_FILE_INCLUDE_DIR 关键字，
并在如下这句后

ocv_include_directories(${OPENCV_CONFIG_FILE_INCLUDE_DIR})

添加如下这句

ocv_include_directories(./3rdparty/zlib/)

问题二：

opencv-4.1.0/modules/core/src/parallel.cpp:267:14:
error: ‘exception_ptr’ in namespace ‘std’ does not name a type std::exception_ptr pException;

在 opencv-4.1.0/modules/core/src/parallel.cpp 中查找 CV__EXCEPTION_PTR 关键字，

添加如下这句

undef CV__EXCEPTION_PTR // Add this line, disable the EXCEPTION_PTR

在如下内容之上

ifndef CVEXCEPTION_PTR
define CVEXCEPTION_PTR 0
elif CV__EXCEPTION_PTR
include // std::exception_ptr
endif

问题三：

WARNING: Can't build ffmpeg test code

1.自测 ffmpeg_test.cpp 是否可以编译通过
cd /home/nsc/workspace/opencv-4.1.0/cmake/checks

arm-himix200-linux-gcc ffmpeg_test.cpp -o ffmpeg_test \
-I /home/nsc/workspace/himix200_ffmpeg_install/include \
-I /home/nsc/workspace/himix200_x264_install/include \
-L /home/nsc/workspace/himix200_ffmpeg_install/lib \
-L /home/nsc/workspace/himix200_x264_install/lib \
-lavformat -lavcodec -lavdevice -lavfilter -lavutil -lpostproc -lswresample -lswscale \
-lx264 \
-lm -lpthread


  1. 方法一：编译时找到 x264 库
    将 /home/nsc/workspace/himix200_x264_install/include 目录下的
    x264.h
    x264_config.h
    拷贝到 /home/nsc/workspace/himix200_ffmpeg_install/include 目录下

将 /home/nsc/workspace/himix200_x264_install/lib 目录下的 libx264.a 拷贝到
/home/nsc/workspace/himix200_ffmpeg_install/lib 目录下

方法二：修改 detect_ffmpeg.cmake 文件，在执行 make 时便知问题在哪里了
if(HAVE_FFMPEG AND NOT HAVE_FFMPEG_WRAPPER AND NOT OPENCV_FFMPEG_SKIP_BUILD_CHECK)
try_compile(__VALID_FFMPEG

  "${OpenCV_BINARY_DIR}"  
  "${OpenCV_SOURCE_DIR}/cmake/checks/ffmpeg_test.cpp"  
  CMAKE_FLAGS "-DINCLUDE_DIRECTORIES:STRING=${FFMPEG_INCLUDE_DIRS}"  
              "-DLINK_LIBRARIES:STRING=${FFMPEG_LIBRARIES}"  
  OUTPUT_VARIABLE TRY_OUT

)
if(NOT __VALID_FFMPEG)

 message(FATAL_ERROR "FFMPEG: test check build log:\n${TRY_OUT}")  
message(STATUS "WARNING: Can't build ffmpeg test code")  
set(HAVE_FFMPEG FALSE)

endif()

注释掉上面的判断检测，直接返回TRUE

set(HAVE_FFMPEG TRUE)
endif()
