"이 프로세서에서 지원되지 않는 opcode : mips32r2"와 함께 MIPS 대상에 대한 Valgrind 3.10.0 컴파일에 실패했습니다

Question

mips32r2에 대해 valgrind 3.10.0을 교차 컴파일하려고하지만 컴파일하는 동안 다음 오류가 발생합니다. 아무도이 문제에 대해 도움을 줄 수 있습니까?

다음 구성 단계를 수행했습니다.

Answer 1

불평하는 모든 opcode는 부동 소수점 연산입니다. 타겟 프로세서에 하드웨어 부동 소수점 유닛이없는 것 같습니다. gcc 명령 행에 -msoft-float 옵션을 추가하십시오.
