How To Install robin-map-devel on CentOS 8
Introduction
In this tutorial we learn how to install robin-map-devel on CentOS 8.
What is robin-map-devel
The robin-map library is a C++ implementation of a fast hash map and hash set using open-addressing and linear robin hood hashing with backward shift deletion to resolve collisions. Four classes are provided and tsl policy, the last two use a prime growth policy instead and are able to cope better with a poor hash function. Use the prime version if there is a chance of repeating patterns in the lower bits of your hash (e.g. you are storing pointers with an identity hash function). See GrowthPolicy for details. A benchmark of tsl page also gives some advices on which hash table structure you should try for your use case (useful if you are a bit lost with the multiple hash tables implementations in the tsl namespace).
We can use yum or dnf to install robin-map-devel on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install robin-map-devel.
