c++ - Opencv 构建错误：针对符号“ff_pw_9”重新定位 R_X86_64_PC32 ... 使用 -fPIC 重新编译
问题描述
我正在尝试像这样构建opencv：
wget -nc -O opencv.tar.gz https://github.com/opencv/opencv/archive/4.1.2.tar.gz
wget -nc -O opencv_contrib.tar.gz https://github.com/opencv/opencv_contrib/archive/4.1.2.tar.gz
echo extracting opencv
tar xzf opencv.tar.gz
tar xzf opencv_contrib.tar.gz

但是当我成功的时候，我突然明白了：

/usr/bin/ld: /usr/local/lib/libavcodec.a(vc1dsp_mmx.o): relocation R_X86_64_PC32 against symbol `ff_pw_9' can not be used when making a shared object; recompile with -fPIC

这是什么，我该如何解决？
