RHEL 7에서 gcc를 gcc-4.9로 업그레이드

redhat 7에는 gcc 4.8.5가 있습니다.

4.9로 업그레이드하고 싶습니다. 이를 위해 아래 명령을 사용했습니다.

sudo yum install devtoolset-3-gcc.x86_64

그리고 나는 아래 응답을 얻었다

mpfr이 설치되어 있음을 확인했습니다

또한 gmp가 설치되어 있는지 확인했습니다.

그러나 둘 다 이미 내 시스템에 존재합니다. 여기에 빠진 것이 있습니까? RHEL 7에서 gcc 버전 4.9를 어떻게 설치합니까?

2000 년 "redhat 7"이 아니라 RHEL 7 : Redhat Enterprise Linux 7

참고 : devtoolset-3은 gcc / g ++의 업데이트가 아니라 EL7에 사용할 수있는 추가 컴파일러 중 하나 일뿐입니다. 즉, 원하는만큼 많은 gcc 버전을 동시에 설치할 수 있습니다. 시스템 컴파일러가 설치되어 있는지 확인하십시오 : #yum install gcc-c++

필요 : libmpfr.so.1 () (64bit)

필요 : libgmp.so.3 () (64bit)

"devtoolset-3"은 오래되었습니다 (RHEL 6) : 1)이 패키지를 설치하십시오 (EL7 용, 'Jan 2015'용) .... compat-libgmp-4.3.1-1.sl7.x86_64.rpm, compat-libmpfr-2.4.1-1.sl7.x86_64.rpm

링크, compat-libgmp https://drive.google.com/file/d/0B7S255p3kFXNZFJDdWtkV3RyZTA/view?usp=sharing ... 및 compat-libmpfr https://drive.google.com/file/d/0B7S255p3kFXNV0FoOVlPemRBS0k/view ? usp = 공유

# cd Downloads/ && yum install compat-libgmp-4.3.1-1.sl7.x86_64.rpm compat-libmpfr-2.4.1-1.sl7.x86_64.rpm

2) 완전한 devtoolset-3이 필요하지 않습니다. 이것은 gcc-4.9 / g ++-4.9 : # yum install devtoolset-3-gcc-c++... 총 ~ 4 패키지를 설치합니다. ... 'gfortran':# yum install devtoolset-3-gcc-gfortran

gcc-4.9, g ++-4.9 : $ scl enable devtoolset-3 bash... 및 $ gcc -v를 활성화 하면 "gcc version 4.9"라고 표시됩니다 (설정은 터미널을 종료 할 때까지 유효합니다).
