ubuntu16.04安装opencv3.1

opencv3.1安装见http://www.cnblogs.com/simplelovecs/p/5156458.html

1.  error: ‘GstEncodingProfileClass’ does not name a type

 typedef GstEncodingProfileClass GstEncodingAudioProfileClass;

发现只安装了libgstreamer1.0，未安装libgstreamer-plugins-base1.0

执行sudo apt-get install libgstreamer-plugins-base1.0-dev 即可。

2.  lib/libopencv_videoio.so.3.1.0: undefined reference to `gst_app_sink_pull_sample'

collect2: error: ld returned 1 exit status
modules/video/CMakeFiles/opencv_test_video.dir/build.make:388: recipe for target 'bin/opencv_test_video' failed
make[2]: *** [bin/opencv_test_video] Error 1

找到"OpenCVCompilerOptions.cmake"文件

add_extra_compiler_option(-Werror=non-virtual-dtor)

一行添加 #
