HOWTO: Creating a Local Yum Repository Using an ISO Image on CentOS 7.0

1. Create a mount point, for example /mnt/CentOS

 [ ]# mount -o loop CentOS-7-x86_64-Everything-1611.iso/mnt/CentOS


2. In the /etc/yum.repos.d directory, add and edit the repository files, such as CentOS-ISO.repo

[c7-iso]
name=CentOS-$releasever - ISO
baseurl=file:///mnt/CentOS/
gpgcheck=0
enabled=1



3. Clean up the yum cache

 [ ]# sudo yum clean all


4. Install RPM package

 [ ]# sudo yum --disablerepo=\* --enablerepo=c7-iso install "package name"

Install the 32-bit C library:

 [ ]# sudo yum --disablerepo=\* --enablerepo=c7-iso install glibc.i686

How to switch GCC version on Ububtu

I had installed GCC version 4.9 and 5.4 from the Ubuntu repositories. How to switch GCC version?
You can switch the symlinks yourself manually, but using "update-alternatives" makes it easy.

[ ]$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 100 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9
[ ]$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 50 --slave /usr/bin/g++ g++ /usr/bin/g++-5 

Now you can switch between these versions by using:

[ ]$ sudo update-alternatives --config gcc

Change GCC 9 (Ubuntu 22.04)

[ ]$ sudo apt install gcc-9
[ ]$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 100
