如何在docker centos7中安装gcc7

问题描述 投票:0回答:2

我正在尝试基于centos7构建一个泊坞窗图像

FROM centos:centos7

RUN yum -y update
RUN yum -y install gcc
RUN gcc --version

安装的gcc是4.8:

 4/4 : RUN gcc --version

我该如何安装gcc7?我试过devtools-7,它不起作用:

FROM centos:centos7

RUN yum -y update
RUN yum -y install scl-utils
RUN yum -y install devtoolset-7-gcc
RUN scl enable devtoolset-7 bash
RUN gcc --version

我有:

Step 4/6 : RUN yum -y install devtoolset-7-gcc

RUN make

RUN make install

为了节省构建时间,您可以使用“docker commit”从正在运行的docker创建一个新的docker,或者将/ usr / local保存到tar文件中,并在任何其他新的centos7 docker上打开它。

显然,您当前的存储库配置中不存在devtoolset-7-gcc。尝试添加一个拥有它的回购,或尝试yum -y install centos-release-scl而不是yum -y install scl-utils

在这里找到它:http://blog.stevedoria.net/20180214/how-to-install-gcc-7-on-centos-7

玩得开心!

编辑:

经过一些更多的研究,似乎确实安装了gcc 7,但scl enable实际上是打开一个包含你的GCC 7的新bash。如果你真的需要GCC 7作为默认的gcc,你可以从源代码编译它(但是它需要一个loooong时间),或者您可以使用dockerfile中的SHELL命令在shell之间交替。这是我的docker文件:

FROM centos:centos7

RUN yum -y update
RUN yum -y install centos-release-scl
RUN yum -y install devtoolset-7-gcc*
SHELL [ "/usr/bin/scl", "enable", "devtoolset-7"]
RUN gcc --version

RUN gcc --version的输出

在使用devtoolset时,shell之间的交替似乎是预期的方法,因为它允许您在需要时快速切换版本。我希望这有帮助
