终端运行

cmake-gui

配置源码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70][]

点击"configure"按钮，会显示很多配置项：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 2][]

对于以上出现的错误项，事先下载好，配置再.cache文件夹下即可，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 3][]

同时事先下载好opencv的第三方库extra。继续点击“configure”按钮：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 4][]

如果需要Python编译，就修改一些Python编译的选项。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 5][]

以上红色信息是由OPENVB\_GENERATE\_STATUS该选项勾选造成的，可以去掉，也可以忽略。可以勾选掉java等选项，继续点击"configure",

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 6][]

可以配置OpenCV的Python编译环境、安装路径 prefix等，点击”configure“按钮，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 7][]

直到需要的选项，没有出现红色的行为止：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 8][]

然后点击 "Generate"按钮，即可。

这时候进入build路径，启动终端，点击”make“,

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 9][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 10][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 11][]

编译过程中，有可能会出现以下错误：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 12][]

这是因为在编译过程中，有可能环境变量没有配置完成：

![20200611082948151.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 13][]

配置环境变量的方法有两种，

一种是在/etc/profile文件中，配置LD\_LIBRARY\_PATH的值。

/usr/local/cuda-10.1/lib64:
    /usr/local/opencv/lib:
    /lib/x86_64-linux-gnu:
    /usr/lib/x86_64-linux-gnu:
    /home/pytorch/anaconda3/lib:

特别要注意/lib/x86\_64-linux-gnu 和 /usr/lib/x86\_64-linux-gnu，

如果需要python编译，而环境是由Anaconda环境搭建，那么一定要配置/home/pytorch/anaconda3/lib

一种是配置/etc/ld.so.conf，然后利用命令 ldconfig，将其缓存到/etc/ld.so.cache中去。

记录一些细节：

1：出现的红色提示信息，可以通过去掉 OPENCV\_GENERATE\_SETUPVARS的勾选框，默认是勾选的，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 14][]

去掉勾选框即可：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 15][]

2：有必要生成 OPENVB\_GENERATE\_PKGCONFIG，这样就可以使用PKG\_CONFIG命令了，勾选此选项：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d4Y2R6aGFuZ3Bpbmc_size_16_color_FFFFFF_t_70 16][]

3：出现了一下错误：

重新进行

make

然后顺利编译通过
