【问题描述】

鲲鹏环境下编译vlc 3.0.16执行make过程报relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `stderr@@GLIBC_2.17'等错误，具体报错如下：

/usr/bin/ld: /usr/local/lib/libavutil.a(log.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `stderr@@GLIBC_2.17' which may bind externally can not be used when making a shared object; recompile with -fPIC

【解决方法】

1、重新编译ffmpeg-4.0，先执行CFLAGS=-fPIC ./configure，然后执行make && make install编译；

2、然后重新编译vlc 3.0.16，先执行./bootstrap，接着执行./configure，然后支持make && make install编译。
