Debian에서 OpenBroadcaster 컴파일하기

아래 설명에 따라 데비안에서 obs를 컴파일해 보세요:https://github.com/jp9000/obs-studio/blob/master/installation 나에게 다음과 같은 오류가 발생합니다.

Linking C shared library libobs.so
/usr/bin/ld: /usr/local/lib/../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

컴파일을 시도했지만 -fPIC다음과 같은 오류가 발생합니다.
