如何安装/配置多个GCC版本?

问题

除此之外,我在Dockerfile中有以下内容,它安装了gcc 5.3.1和gcc 6.3.1:

FROM centos:7

RUN yum install deltarpm -y && \
    yum install -y \
        centos-release-scl \
        epel-release && \
    yum install -y \
        devtoolset-4-gcc*-5.3.1 \
        devtoolset-6-gcc*-6.3.1 \
        glibc-*-2.17

当我执行./configuremake或类似时,定义使用哪个GCC版本的正确方法是什么?

我尝试了什么

当我刚安装了一个devtoolset / GCC版本时,我通过在执行PATH或{{1}之前设置CCCXX./configure个环境变量来成功构建}}:

make

当安装两个GCC版本时,我现在尝试了这个(结果不成功):

# gcc 6.3.1
ENV PATH="/opt/rh/devtoolset-6/root/usr/bin:${PATH}"
ENV CC=/opt/rh/devtoolset-6/root/usr/bin/gcc
ENV CXX=/opt/rh/devtoolset-6/root/usr/bin/g++

RUN \
    cd app1 && \
    ./configure && \
    gmake && \
    gmake install

(部分)错误(来自建筑物Qt4):

ENV original_path="${PATH}"

# gcc 6.3.1
ENV PATH="/opt/rh/devtoolset-6/root/usr/bin:${original_path}"
ENV CC=/opt/rh/devtoolset-6/root/usr/bin/gcc
ENV CXX=/opt/rh/devtoolset-6/root/usr/bin/g++

RUN \
    cd app1 && \
    ./configure && \
    gmake && \
    gmake install

# gcc 5.3.1
ENV PATH="/opt/rh/devtoolset-4/root/usr/bin:${original_path}"
ENV CC=/opt/rh/devtoolset-4/root/usr/bin/gcc
ENV CXX=/opt/rh/devtoolset-4/root/usr/bin/g++

RUN \
    cd app2 && \
    ./configure && \
    gmake && \
    gmake install

我也试过了,但这仍然无效:

这会在某些构建过程中产生看似随机的错误,这些错误在将多个devtools / gcc安装引入混合之前并未出现。

据我所知,一个人应该可以在同一个系统上安装多个gcc: https://gcc.gnu.org/faq.html#multiple
- 那我在这里做错了什么?

证明这可行:

FROM centos:7.3.1611

RUN yum install deltarpm -y && \
    yum install -y \
        centos-release-scl \
        epel-release && \
    yum install -y \
        # gcc 5.3.1 (via Devtools which is equivalent of RedHat DTS)
            devtoolset-4-gcc*-5.3.1 \
            make \
        # gcc 6.3.1 (via Devtools which is equivalent of RedHat DTS)
            devtoolset-6-gcc*-6.3.1 \
            devtoolset-6-make* \
        # glibc 2.17
            glibc-*-2.17

RUN \
    cd app1 && \
