无法在 Ubuntu 14.10 上安装最新版本的 OpenCV

  • 772

我尝试使用此处的说明安装 opencv，但每次都会出现错误

Linking CXX shared library ../../lib/libopencv_videoio.so
/usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): relocation R_X86_64_32 against.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libavcodec.a: error adding symbols: Bad value

make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
Makefile:133: recipe for target 'all' failed
make: *** [all] Error 2

当我运行cmake -D CMAKE_BUILD_TYPE=RELEASE ..时，它说一切都很好并且库已安装。可能会发生什么，我该如何解决？

    参考这个 StackOverflow 问题：Installing OpenCV in Ubuntu 14.10

    您可以根据 OpenCV 的需要cmake使用-D WITH_FFMPEG=OFF或手动编译版本 9 的 FFmpeg。
