개요
안녕하세요 피터입니다.
Linux에 개발환경을 구축하기 위해서는 컴파일러(Compiler) 설치가 필수입니다.
C언어 컴파일러는 gcc, C++언어 컴파일러는 g++ 인데 OS 설치 시 최소설치(Minimum)으로 설치한 경우 설치가 안되어 있는 경우가 있습니다.
이런 경우 리눅스에서 제공하는 yum이라는 패키지 관리 도구를 이용해서 쉽게 설치할 수 있습니다.
gcc 설치
yum을 이용해 아래 명령어로 설치해줍니다.
yum install gcc
[root@peterdev test]# yum install gcc

gcc를 사용하기 위해서는 보시는바와 같이 glibc-devel, kernel-headers 등과 같이 필수적으로 요구되는 rpm 들이 존재합니다. yum을 이용하면 이러한 의존성(dependency) 자동으로 추적하여 관련된 rpm들을 한번에 설치해주기 때문에 개별적으로 설치하는 것에 비해 굉장히 편리합니다.
일부는 새로 설치되고 일부는 업데이트 되는군요.
y 를 누르고 계속 진행합니다.
