크로스 컴파일 문제

Question

나는 다음과 같이 크로스 컴파일러가 작동 할 수 있음을 보여주고 내가 명령 line.The 명령 줄에서 arm-linux-gnueabihf-gcc -v를 입력 할 때 십자가가 우분투 16.04.And에서 도구를 컴파일 설치 :

그 이유는 어떤 이유로이 문제가 발생할 수 있습니까? 어떻게 해결할 수 있습니까? 감사합니다.

Answer 1

툴체인 경로를 내 보낸 적이 있습니까? 당신은 그렇게해야합니다. 일하기 위해서.

내 보낸 것을 알 수있는 방법이나 없습니까?

유형 echo $PATH 터미널에 경로가 표시됩니다.

---

해결 방법 : 툴체인 경로를 내 보냅니다.

다음은 툴체인 경로의 예입니다. 툴 체인의 올바른 경로를 제공해야합니다.

는

예 :

export PATH=/opt/your_toolchains/path/arm-unknown-linux-gnu/bin/:$PATH 

Answer 2

음, 팔 - 리눅스 - gnueabihf-GCC 그것을 수행, configure 스크립트에 의해 인쇄 된 목록의 일부가 아닌 것 같다? 하지만 arm-linux-gnueabihf-g ++에 대한 확인이 표시됩니다. 저거 하나도 설치되어 있습니까?
