最近因为项目需要，在centos上编绎安装了一次opencv及ffmpeg支持，中间血泪史，说与谁人知？
准备工作
- 安装cmake
- 编绎安装ffmpeg，在此不再赘述。
- 下载opencv-340的源码包https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/3.4.0/opencv-3.4.0.zip/download，并解压
yum -y install cmake make gcc-c++
unzip opencv-3.4.0.zip
cd opencv-3.4.0
mkdir build
cd build
依赖检测
在解压后的opencv-3.4.0目录下，创建目录build

坑1：缺少依赖模块或库

注意一下输出，反正里面有很多很多Qt字样的就是了，Qt安装太麻烦，只安装开发库我推荐yum -y install qt5-*-devel，一次断根，管它是啥，全装上完事，这一步也通过了。
缺少其它模块或库
注意上面模块检查的输出，比如：Could NOT find JPEG (missing: JPEG_LIBRARY JPEG_INCLUDE_DIR)或Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR)，我都通过yum search XXX查一下，如果结果里有比如libXXX-devel类似的包，我就直接yum -y install xxx-devel走起，能装一个是一个，虽然其实像png、tiff之类的不是必需的一些东西，但是能通过的更多心里也更带劲一些。
神坑：ffmpeg居然没有启用成功

- 找是通过谁检查的，翻遍了所有.cmake文件，找到了
OpenCVFindLibsVideo.cmake，里面调用了ocv_check_modules(FFMPEG libavcodec libavformat libavutil libswscale)，这里就是检查这些模块是否存在的地方了，那么问题来了，ocv_check_modules是基于什么东西进行的检查呢？ grep ocv_check_modules *.cmake，搜了一把，在OpenCVUtils.cmake里找到了定义，最终调用了pkg_check_modules()方法，看来是调用pkg-config命令行工具进行的开发库版本检查。- 那么
pkg-config又是怎么检查有没有这个开发库的呢？我在/usr/local/lib/及/usr/local/include目录下都有libavcodec的相关.h或.a文件的啊。找了半天不知所措，输入了man pkg-config命令，看到如下介绍：
原来是依赖于/usr/lib/pkgconfig、/usr/share/pkgconfig、/usr/local/lib/pkgconfig等几个目录下的.pc文件来检查的，打开了个文件瞅了一瞅，几个普通的文本文件，声明了头文件的路径和版本、介绍信息等，大不了自己手写一下。 - 不过其实ffmpeg的源代码包下有相关的
.pc文件，find /path/to/ffmpeg -name *.pc一下就全部找到了，全部复制到了/usr/share/pkgconfig目录下后，输入pkg-config --list-all|grep libav己经有结果了，这几个依赖项的检查也通过了。
编绎
# 编绎，依CPU核数指定j参数值，并行编绎
make -j8
坑1：undefined reference to `gluPerspective'
解决办法：删除opencv-3.4.0/samples/cpp/detect_mser.cpp 原因是因为新版本的GLU（）己经舍弃了gluPerspective方法了，官方的解决办法是给出一段替代代码，我稍微试了一下就放弃了，直接删了这个样例文件，然后重新来一次就完事了。 https://www.khronos.org/opengl/wiki/GluPerspective_code
坑2：未编绎出opencv_java340.jar
注意：在第一步时，确保Java那一块的依赖检查，必须ant、JNI、Java Wrappers此三项的检查结果都为YES才行，也就是你必须要安装有 * Apache Ant * Oracle JDK 或 openjdk yum install java-1.8.0-openjdk-devel
Java Wrappers才会变成YES，才会编绎出jar包。
安装
make install
这一步基本上不会出现什么妖蛾子。。。。
开发依赖库
build/lib目录下的所有.so及.so.x都是我们在java开发时所需要的，可以复制到其它的centos系统下使用。
总的来说，这次安装之路曲折不堪，总算是完成了，编绎安装的时候，对于出现的错误提示，仔细的多看看，上网上多找找，总会找到办法的。
