[GDB][OSX] Mac 에 gdb 설치하기

Linux 와는 다르게 OSX에는 gdb 가 기본적으로 설치되어 있지 않아서 설치하느라 이곳저곳 찾아봤는데 제대로 된 곳을 발견했다.


리리와 포포 - [맥] MAC에 GDB 설치하기!



내가 작업한 부분을 정리해서 올린다.


설치방법은 의외로 간단하다.

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

Mac OS X provides similar software, and installing this software in
parallel can cause all kinds of trouble.

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

LDFLAGS: -L/usr/local/opt/readline/lib
CPPFLAGS: -I/usr/local/opt/readline/include

gdb 설치 후 run 명령어를 하려면 인증서 작업을 해줘야 한다.




Launchpad 에서 유틸리티/기타 선택 후 '키체인 접근' 아이콘 클릭

키체인 접근 메뉴 => 인증서 지원 => 인증서 생성

다음과 같이 셋팅 (이름은 임의로 지정)

다음과 같이 셋팅

'계속' 버튼을 여러번 누른 후 '인증서에 대한 위치 지정' 항목이 나오면 다음과 같이 셋팅 후 '생성' 버튼 클릭

'완료' 버튼 클릭

키체인 항목에서 '시스템' 선택 후 방금 생성한 키체인의 정보가져오기 선택

'신뢰' 부분에서 '항상 신뢰'를 선택

위의 설정이 되면 인증서 아이콘이 아래와 같이 변경됨.

다음과 같이 명령어 입력 후 재부팅

1004lucifer:~ 1004lucifer$ 
1004lucifer:~ 1004lucifer$ codesign -s gdb-cert /usr/local/bin/gdb
1004lucifer:~ 1004lucifer$ 

PS.
gdb 설치만 하고 인증서 작업을 하지 않은경우 디버깅 시 run 명령 시 다음과 같은 문제가 발생된다.
