Issue
Question
Among other things, I have the following in a Dockerfile, which installs gcc 5.3.1 and 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
When I execute ./configure, make or similar, what is the proper approach to define which GCC version to be used?
What I have tried
When I just had one devtoolset/GCC version installed, I successfully built by setting PATH, CC, CXX environment variables prior to executing ./configure or make:
# gcc 6.3.1
ENV PATH="/opt/rh/devtoolset-6/root/usr/bin:${PATH}"
ENV CC=/opt/rh/devtoolset-6/root/usr/bin/gcc
ENV CXX=/opt/rh/devtoolset-6/root/usr/bin/g++
RUN \
cd app1 && \
./configure && \
gmake && \
gmake install
And when having both GCC versions installed, I now tried this (with unsuccessful results):
ENV original_path="${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
The (partial) error (from building Qt4 from source):

I also tried this, but this still doesn't work:
# Custom environment variables
ENV original_path="${PATH}"
ENV path_gcc531="/opt/rh/devtoolset-4/root/usr/bin:${original_path}"
ENV cc_gcc531=/opt/rh/devtoolset-4/root/usr/bin/gcc
ENV cxx_gcc531=/opt/rh/devtoolset-4/root/usr/bin/g++
ENV path_gcc631="/opt/rh/devtoolset-6/root/usr/bin:${original_path}"
ENV cc_gcc631=/opt/rh/devtoolset-6/root/usr/bin/gcc
ENV cxx_gcc631=/opt/rh/devtoolset-6/root/usr/bin/g++
RUN \
cd app1 && \
# gcc 6.3.1
PATH="${path_gcc631}" CC="${cc_gcc631}" CXX="${cxx_gcc631}" ./configure && \
PATH="${path_gcc631}" CC="${cc_gcc631}" CXX="${cxx_gcc631}" gmake && \
PATH="${path_gcc631}" CC="${cc_gcc631}" CXX="${cxx_gcc631}" gmake install
RUN \
cd app2 && \
# gcc 5.3.1
PATH="${path_gcc531}" CC="${cc_gcc531}" CXX="${cxx_gcc531}" ./configure && \
PATH="${path_gcc531}" CC="${cc_gcc531}" CXX="${cxx_gcc531}" gmake && \
PATH="${path_gcc531}" CC="${cc_gcc531}" CXX="${cxx_gcc531}" gmake install
This generates seemingly random errors during some builds which didn't appear prior to introducing more than one devtools/gcc install into the mix.
From what I understand, one should be able to have multiple gcc installations on the same system:
https://gcc.gnu.org/faq.html#multiple
- So what am I doing wrong here?
Solution
Turns out this worked:
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 && \
# gcc 6.3.1
scl enable devtoolset-6 './configure' && \
scl enable devtoolset-6 'gmake' && \
scl enable devtoolset-6 'gmake install'
RUN \
cd app2 && \
# gcc 5.3.1
scl enable devtoolset-4 './configure' && \
scl enable devtoolset-4 'gmake' && \
scl enable devtoolset-4 'gmake install'
