ucLinux libbzip2 크로스 컴파일 할 때 reloc 유형 오류가 발생했습니다.

Question

libcurl이 포함 된 ucLinux를 컴파일하려고했지만 libbzip2를 컴파일 할 때 barfs 구성에 컬을 포함시킬 때가 있습니다.

저는 coldfire 68K 프로세서에 대해 이것을 크로스 컴파일하고 있습니다.

재배치 유형이 PIC에 대해 지원되지 않지만이 문제를 해결할 방법이 없습니다. 어쨌든 모든 라이브러리를 PIC로 컴파일 할 필요가 있다는 인상하에있었습니다.

나는 -msep-data 플래그를 노크 (또는 후 -mno-sep-data 퍼팅)이 경고가 사라질 수 있음을 발견 : 여기

이 출력됩니다. GCC doc page에서 :

데이터 세그먼트가 텍스트 세그먼트에서 메모리의 다른 지역에 위치 할 수 있도록 코드를 생성합니다. 이를 통해 가상 메모리 관리 기능이없는 환경에서 실행을 제자리에서 실행할 수 있습니다. 이 옵션은 -fPIC을 의미합니다.

-fPIC 또는 -fno-PIC도 아무런 효과가 없다는 것을 알았습니다.
