32位可以用吗

[dirtyluke]

32位ubuntu按照doc顺序安装，到最后检测的时候检测不出来（16.04）.另外64位上用docker安装成功后可以显示图片吗

[hihozhou]

使用docker的话估计GUI部分可能无法使用，32位的安装和64位的ubuntu安装时一样的

pkg-config --libs opencv4 Package opencv4 was not found in the pkg-config search path. Perhaps you should add the directory containing `opencv4.pc' to the PKG_CONFIG_PATH environment variable No package 'opencv4' found

@hihozhou 试了一下，需要在CMAKE的时候加上 -D OPENCV_GENERATE_PKGCONFIG=YES 参数 https://github.com/opencv/opencv/issues/13154 貌似不是每个人的电脑都会出现这种问题，顺便问一下原来的 https://doc.phpopencv.org/这个关掉了么
