나는이 컴파일 할 때 나는 오류를 다음 얻을 리눅스에서 공유 라이브러리를 만들기 위해 노력하고 컴파일 할 때 -fPIC 평균은 무엇을 : 내가 GetCrc16의 내용을 제거하면공유 라이브러리
relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
을 그것은 작동합니다. 내가 도대체 뭘 잘못하고있는 겁니까 ?

"공유 객체를 만들 때 ... 사용할 수 없습니다 ** ** -fPIC으로 컴파일" – Mat
@Mat 당신이 내가 새로운 오전보다 구체적인 수 linux.fpic을 사용하여 다시 컴파일하려고 시도하지만 그 이유는 무엇입니까? – opc0de
'-fPIC' 플래그로 코드를 재 컴파일해야합니다. – Mat
