下载安装过程
配置gcc
建立一个输出目录,编译时所有生成的中间文件都放到该目录下:
mkdir gcc-temp
工作目录切换至输出目录,并在其中执行配置和安装:
cd gcc-temp
执行configure
配置安装文件:
../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
配置完成后,执行以下命令,编译gcc
:
make
编译过程较长,耐心等待。编译完成后,安装gcc
:
make install
安装完成后还需要替换系统默认的gcc
,执行以下命令,查找6.2
版本的安装文件:
ls /usr/local/bin | grep gcc
执行升级命令:
/usr/sbin/update-alternatives --install /usr/bin/gcc gcc /usr/local/bin/x86_64-pc-linux-gnu-gcc-6.2.0 52
验证安装
查看版本号
gcc -v
到此说明安装成功了。
