How To Install libbitmask1 on Ubuntu 22.04
Introduction
In this tutorial we learn how to install libbitmask1 on Ubuntu 22.04.
What is libbitmask1
libbitmask1 is:
This Bitmask library supports multi-word bitmask operations for applications programmed in ‘C’. It works in conjunction with recent Linux kernel support for processor and memory placement on multiprocessor SMP and NUMA systems. The cpuset library, being developed in parallel, depends on this bitmask library.
Bitmasks provide multi-word bit masks and operations thereon to do such things as set and clear bits, intersect and union masks, query bits, and display and parse masks.
The initial intended use for these bitmasks is to represent sets of CPUs and Memory Nodes, when configuring large SMP and NUMA systems. However there is little in the semantics of bitmasks that is specific to this particular use, and bitmasks should be usable for other purposes that had similar design requirements.
These bitmasks share the same underlying layout as the bitmasks used by the Linux kernel to represent sets of CPUs and Memory Nodes. Unlike the kernel bitmasks, these bitmasks use dynamically allocated memory and are manipulated via a pointer. This enables a program to work correctly on systems with various numbers of CPUs and Nodes, without recompilation.
There is a related cpuset library which uses the bitmask type provided here to represent sets of CPUs and Memory Nodes. The internal representation (as an array of unsigned longs, in little endian order) is directly compatible with the sched_setaffinity(2) and sched_getaffinity(2) system calls (added in Linux 2.6).
There are three methods to install libbitmask1 on Ubuntu 22.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install libbitmask1 Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install libbitmask1 using apt-get by running the following command:
sudo apt-get -y install libbitmask1
Install libbitmask1 Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install libbitmask1 using apt by running the following command:
sudo apt -y install libbitmask1
Install libbitmask1 Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install libbitmask1 using aptitude by running the following command:
sudo aptitude -y install libbitmask1
How To Uninstall libbitmask1 on Ubuntu 22.04
