안녕하세요.
궁금한 사항이 있어서 이렇게 질문을 다시 올리게 되었네요 ^^
크로스컴파일된 gcc의 버전을 알고 싶은데요 ....
# arm-unknown-linux-gnu-gcc --version

이렇게 하면 3.4.1 버전이라는 것을 알 수 있잖아요.
제가 알고 싶은 것은 gcc의 버전이 아니라 arm버전이거든요.

-v옵션을 주니 이렇게도 나오네요. 그래서 스펙 파일을 보았는데
아래와 같네요.

역시 gcc버전만 나와있고 arm버전은 알 수가 없네요...
혹시 arm버전을 알 수 있는 방법이 있을까요???
밑에쯤에...

이런녀석이 나옵니다. 이 녀석들을 지원한다고 보시면 됩니다.
대신 컴파일시 mcpu나 march 옵션을 줘야합니다.
