无法在 Ubuntu 14.10 上安装最新版本的 OpenCV

我尝试使用以下说明安装 opencv这里但我每次都会收到错误

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

make: *** [all] Error 2

当我运行时，cmake -D CMAKE_BUILD_TYPE=RELEASE ..它显示一切正常，并且库已安装。可能发生什么情况？我该如何解决？

参考这个 StackOverflow 问题：在 Ubuntu 14.10 中安装 OpenCV

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