[Experience] using Docker as a compilation library environment summary

Upgrade gcc4.8.4, encounter some of the pits summarized here.

The first thing to do is to check which mirrors Docker has:
Docker images
We found the image we wanted.

First, remove the previously restricted Docker container:

Docker RM $ (Docker ps-a-Q)

Then delete some images without tag.

Docker RMI $ (Docker images | grep "^<none>" | awk "{print $}")

Now it's time to do something:

Prepare the Docker File in the directory:

From Centos:6

And then execute

Docker build-t "Docker_gcc_4_8_4"

This step generates a basic Docker environment

Then log on to the appropriate machine and perform the following:

Docker run-it-v/data/tmp/:/tmp/--name BUILD_GCC 127.0.0.1:8000/docker_gcc_4_8_4/bin/bash

So we get into the Docker environment.

Here's how to perform the upgrade:
Back up the original GCC first

#!/bin/bash
mkdir-p/data/gcc-bak
bak_list= "/usr/bin/gcc/usr/lib64/libgomp.so.1.0.0/usr/share/info/ Libgomp.info.gz/usr/share/info/dir/usr/bin/c++/usr/bin/g++/usr/share/man/man1/g++.1.gz/usr/bin/cpp/usr/share/ info/cpp.info.gz/usr/share/info/cppinternals.info.gz/usr/share/locale//usr/share/man/man1/cpp.1.gz/usr/lib64/ Libstdc++.so.6 "for
file in $bak _list
does
        cp-r $file/data/gcc-bak/
Done

Then, create the following file in the/etc/ld.so.conf.d/directory

Cat gmp-mpfr-mpc.conf
/usr/local/mpfr-2.4.2/lib/
/usr/local/mpc-0.8.1/lib/
/usr/local/gmp-4.3.2/lib /

Then extract the/tmp/lib.tar.gz into the/usr/local directory and perform the Ldconfig update cache.
Try yum to install rpm

Yum Install gcc-4.8.4-1.x86_64.rpm

Find that too much reliance is missing

Finally, the dependency forcing update is ignored:

/bin/rpm-ivh/data/gcc-4.8.4-1.x86_64.rpm--force--nodeps

Write a simple program, verify that there is no problem, the upgrade is complete.

#include <stdio.h>

int main ()
{
  printf ("Hello world\n");
  return 0;
}

There was also a problem with no route to host when using Docker as a push to the Docker private warehouse.
