centos7.4 어떻게 원본 설치 gcc 7.3.0

1. 환경:arm 구조의centos7.4 시스템 서버
2. 현재 gcc 버전 보기: gcc-v

[root@aarch64vm-centos74-011 ~]# gcc -v

3. gcc 7.3.0의 원본 코드를 다운로드합니다.https://mirrors.ustc.edu.cn/gnu/gcc/gcc-7.3.0/gcc-7.3.0.tar.gz
4. 원본을 서버에 업로드하고 압축을 풀기

[root@aarch64vm-centos74-010 ~]# mkdir -p /usr/local/gcc
[root@aarch64vm-centos74-010 ~]# ls /usr/local/
bin  boost  cmake  doc  etc  games  gcc  include  lib  lib64  libexec  man  maven  mysql  sbin  share  src  tomcat
[root@aarch64vm-centos74-010 ~]# ls

[root@aarch64vm-centos74-010 ~]# tar -xvf gcc-7.3.0.tar.gz -C /usr/local/gcc/

5. 압축 해제 완료 후 설치 gcc 원본 코드 컴파일
(1) gcc 7.3.0 디렉터리에 들어가서 download_ 실행prerequisites 스크립트.

(2) 컴파일 출력 디렉터리를 만들고 모든 중간 파일을 디렉터리에 넣습니다.

[root@aarch64vm-centos74-010 gcc-7.3.0]# mkdir gcc-build-7.3.0
[root@aarch64vm-centos74-010 gcc-7.3.0]# cd gcc-build-7.3.0/
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# cp ../gmp-6.1.0.tar.bz2 ./
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# cp ../mpfr-3.1.4.tar.bz2 ./
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# cp ../mpc-1.0.3.tar.gz ./
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# cp ../isl-0.16.1.tar.bz2 ./
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# ls
gmp-6.1.0.tar.bz2  isl-0.16.1.tar.bz2  mpc-1.0.3.tar.gz  mpfr-3.1.4.tar.bz2
[root@aarch64vm-centos74-010 gcc-build-7.3.0]# 

(3) 구성:
현재 디렉토리에서 다음을 수행합니다.
           ../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib 매개변수 해석:
--enable-checking=release//검사를 추가할 수도 있습니다 – disable-checking에서 생성된 컴파일러는 컴파일하는 과정에서 검사를 하지 않습니다.
--enable-languages=c, c++//gcc가 지원하는 프로그래밍 언어;
--disable-multilib//다목적 라이브러리 컴파일 취소(32비트 라이브러리 컴파일 취소).
(4)make 컴파일
현재 디렉터리 실행:make-j4
(번역 시간이 길고 기다려!!!!!!)
(5) 이전 버전의 gcc 마운트 해제, gcc7.3.0 설치
rpm -q gcc  rpm -q gcc-c++
실행 출력된 패키지 이름에 따라 실행rpm -e [ ]  

[root@localhost ~]# rpm -q gcc
gcc-4.8.5-28.el7_5.1.aarch64
[root@localhost ~]# rpm -q gcc-c++
gcc-c++-4.8.5-28.el7_5.1.aarch64
[root@localhost ~]# rpm -e gcc-c++-4.8.5-28.el7_5.1.aarch64
[root@localhost ~]# rpm -e gcc-4.8.5-28.el7_5.1.aarch64

make의 gcc 디렉터리에 들어가서 설치:make install-j8

(2) 이전 버전의 설치 패키지 보기

$:  rpm -q gcc
package gcc is not installed
$: rpm -q g++
package g++ is not installed

(3)yum 직접 설치

$:  yum install  gcc gcc-c++

하면, 만약, 만약...
rpm-q gcc와 rpm-q g++에 설치 패키지가 있으면/etc/profile 파일에 추가하기
#gcc export PATH=$PATH:/usr/bin
/usr/local/bin 디렉터리, mv gcc~와 mv g++~
실행source/etc/profile
gcc 교체 여부 확인
마지막으로 ~/디렉터리의 gcc와 g++를/usr/local/bin으로 이동
