Mac 에서 arm toolchain 설정하기

 맥이든 윈도우든 리눅스든 arm 기반의 디바이스용 코드를 빌드하기 위해서는 arm toolchain 이 필요하다.

맥에서는 간단히 brew uninstall gcc-arm-none-eabi

이렇게 설치를 했는데 정작 어느 경로로 설치가 되었는지 알 수 가 없다

보통 cmake나 make 는 /usr/local/bin에 있는데 

gcc-arm-none-eabi 파일은 찾을수가 없었다. 

 

그래서 몇번 삽질을 하고 검색한 끝에 답을 찾을 수 있었다.

brew cask install gcc-arm-embedded

이렇게 하면 arm-none-eabi 파일들이 /usr/local/bin 에 설치가 된다.

 

이제 IDE에서 툴체인 경로를 설정하면 정상적으로 빌드가 된다.
