내 WIN 7 컴퓨터에 mips32 아키텍처용 코드 소스 크로스 컴파일 도구 체인을 설치했습니다. 먼저 내 라우터에 대한 간단한 MIPS32 기반 "계속" 바이너리를 컴파일하고 싶습니다. 온라인으로 검색해보니 MIPS32 빅엔디안 기반이라는 것을 알았습니다.

다음 컴파일 매개변수를 시도했습니다.
mips-linux-gnu-gcc -mips32 -muclibc -o factorial factorial.c
MIPS 시스템에서 출력 바이너리를 실행하면 "'libgcc_s.so.1' 라이브러리를 로드할 수 없습니다"라고 인쇄됩니다.
mips-linux-gnu-gcc -muclibc -mips32 -static-libgcc -s -o factorial factorial.c
출력을 실행하면 "sigsegv"가 인쇄됩니다.
여기에 문제가 있나요? 어떤 컴파일러 매개변수를 입력해야 합니까? 도와주세요.
고쳐 쓰다:더 많은 정보를 추가했습니다.
