How To Install libr12 on Fedora 36
Introduction
In this tutorial we learn how to install libr12
on Fedora 36.
What is libr12
libr12 computes types integrals that appear in Kutzelnigg’s linear R12 theories for electronic structure. All linear R12 methods, such as MP2-R12, contain terms in the wave function that are linear in the inter-electronic distances r_{ij} (hence the name). Appearance of several types of two-body integrals is due to the use of the approximate resolution of the identity to reduce three- and four-body integrals to products of simpler integrals.
We can use yum
or dnf
to install libr12
on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install libr12.
Install libr12 on Fedora 36 Using dnf
Update yum database with dnf
using the following command.
sudo dnf makecache --refresh
After updating yum database, We can install libr12
using dnf
by running the following command:
sudo dnf -y install libr12
Install libr12 on Fedora 36 Using yum
Update yum database with yum
using the following command.
sudo yum makecache --refresh
After updating yum database, We can install libr12
using yum
by running the following command:
sudo yum -y install libr12
How To Uninstall libr12 on Fedora 36
To uninstall only the libr12
package we can use the following command:
sudo dnf remove libr12
