This wikiHow teaches you how to plan and develop an operating organization if y'all don't know how to code in C, or C++. Operating systems manage calculator hardware and provide the resources that applications demand to run. Writing an operating system from scratch requires a strong command of calculator scientific discipline, a programming language like C or C++, assembly, and code direction practices.

1. 1

   Take some basic Informatics courses. Unlike developing for the web, creating an operating system requires a strong understanding of algorithms, information structures, calculator hardware, and resources management.^[ane] People become degrees in this stuff, and then don't expect to write an entire operating organisation later on reading an online tutorial! Harvard'south Intro to Informatics class is available online through EDX at no price.

   Learn an assembly language. Assembly languages are depression-level languages designed to communicate with unlike processors. Since assembly is different for different processor types (e.g., x86 assembly Linguistic communication for Intel, AMD, VIA, and other processors), yous'll need to learn the version for the type of processor you lot're coding for.

   • This open-source volume, if read in its entirety, can requite you lot a solid enough agreement for building an operating organisation.^[2]
   • The Art of Assembly Language is a highly-recommended book virtually associates bachelor both on and offline.
   • You should also exercise a lot of research on the type of processor(s) on which your operating system should run. The manuals for processor architecture can hands be found using a Google search ("Intel Manuals," "ARM manuals," etc.).

4. 4

   Consummate an operating organization tutorial. OS tutorials volition walk you through the process of creating a basic operating system. This gets you used to the process and helps yous figure out if at that place are any pieces you're missing. Once you've completed a tutorial or two, y'all'll exist well on your way to creating your very ain operating system.

   • Bare Basic is a tutorial that helps yous write your first simple 32-bit kernel. Subsequently completing the tutorial, the next step is to use Meaty Skeleton to construction your own operating system.
   • Linux from Scratch is an online book that walks you through creating your own Linux operating system.
   • Operating systems from 0 to i is a free book nearly creating various operating systems from start to finish.

5. 5

   Figure out your operating system goals. What practise you want your operating system to do? How should it look? Practice you really need to write an entire operating system or are you just looking to create a certain look for your desktop? These are all things to consider before start to code.^[iii]

   • Consider developing with a team of other programmers. Having a team of developers working on the project will cut the evolution time significantly.
   • Add your project goals, plans, and questions to your public repository so it'southward piece of cake for others to assist you lot.

1. 1

   Cull a development environment. This is the platform you'll be using to code your new operating system. It'southward a matter of personal preference, only most people either use Windows or a flavour of UNIX. If yous're using Windows, it's a skilful idea to install a UNIX environment like Cygwin or MinGW. You'll generally want to make sure whatever environment you're using includes the following:

   • GCC (the Gnu compiler). If y'all're using Windows, y'all can install information technology in Cygwin or MinGW.
   • Binutils is a collection of tools used for manipulating object files. Again, if yous're using Windows, you can install it in Cygwin.
   • A good text editor. Vim and emacs are ordinarily used in UNIX environments. Windows users tin can employ Notepad, or check out Notepad++ for a multi-tab upgrade.
   • Perl and/or Python. One or both are recommended for cord manipulation.

2. 2

   Ready your version command system. Writing an operating organisation means you'll likely be creating hundreds (or thousands!) of lines of code. When you're working on revisions, this can go disruptive. Some options to check out are CVS, Mercurial, and Subversion.

3. iii

4. 4

   Choose a kernel pattern. The kernel is the core of your operating organisation, providing an interface between the user and the computer hardware. There are monolithic kernels and micro kernels. Monolithic kernels implement all the services in the kernel, while microkernels have a small kernel combined with user daemons implementing services. In full general, monolithic kernels are faster, but microkernels have better mistake isolation and reliability.

5. v

   Start minor. Begin with small things such as displaying text and interrupts before moving on to things such as memory management and multitasking. You lot can also endeavor making a unproblematic 16-bit Operating System, instead of taking a big leap.

   • You will not have a full arrangement in two weeks. Start with an OS that boots, and so move on to the cool stuff.

6. vi

   Exam your new operating organisation with a virtual machine. Rather than rebooting your calculator each time you make changes or having to transfer the files from your development estimator to your test automobile, use a virtual machine application. VMWare is a common option that works with both Windows and Linux, and then is Bochs. Check for potential deadlocks and other bugs and repair them as needed.

7. seven

   Release a "release candidate." You lot tin can exercise this by uploading your tested code to your public repository. This volition allow people to examination your operating system and report dorsum on whatsoever issues they run into.

8. 8

   Network with other operating system developers. There's an unabridged community of operating arrangement developers congregating on various forums, including /r/osdev on Reddit and the Software Engineering Stack Commutation. One you've gotten a grasp on developing a basic operating system, read existing posts to see what kind of things come up up during the development process.

Add together New Question

• Question

  Tin can I do this if I have no programming feel?

  

  Merely if you're willing to learn a lot. Yous will require a total understanding of at least assembly code, and the motivation to learn more than. Building your ain Os is non a pocket-sized job.

• Question

  What should be my outset step?

  

  Acquire programming languages and concepts, and practise to go a very stiff programmer.

• Question

  Which applications tin can I use to program my operating system?

  

  That depends on the programming language you are using. It is recommended, however, to employ an IDE, or Integrated Development Surroundings, to plan your operating system, as IDEs have built-in tools and features to help brand evolution easier. Not all IDEs support every linguistic communication nonetheless, and then y'all will want to specifically search for IDEs that back up the language (or languages) you're using.

• Question

  Is coding my own kernel better than using an existing kernel?

  

  Getting an open up source kernel is improve than coding one if yous are in uni or something considering y'all're not having to get-go from scratch or pay for it since it is open up source. All the same, coding one proves a higher knowledge in programming, which you lot might prefer.

• Question

  Tin I merge the Windows and Android operating systems?

  

  You lot tin can, but they're both two unlike operating systems and information technology would require a slap-up deal of programming feel and work. Thus, unless you're able to do the programming, don't endeavour information technology.

• Question

  How can I merge Windows and Android operating systems?

  

  Windows is an unstructured OS, not to mention it's not open source, adding functionality to Windows is a pretty tough job. While Android can be said to be a variant of Linux, a structured and open-source Bone, adding functionality layers is easy, but besides many layers event in bad user experience. Dorsum to the question, It would certainly crave y'all have all-encompassing knowledge of Android (you can try cooking an Android rom) and insider-noesis of how some core components of Windows work, so what do you get after merging these two Bone, will information technology be structured or unstructured, to begin with? In that location's as well much ambivalence!

• Question

  How much time would it accept to build a new operating system?

  

  It'd take months if not years to make an Bone that works properly with enough of functionality. There's no possible way you lot can cook up an operating arrangement in a few weeks or days.

• Question

  Can I make an operating system using java only?

  

  Yes, Someone has done that before. Notwithstanding, If you lot want people to actually utilize your Os don't use java. Information technology not simply volition have much, much longer but it will likewise not exist equally practiced equally an Bone fabricated from another coding language. So, you can, yeah, simply should you? Probably non.

• Question

  What are some essential skills for developing an OS?

  

  Yous need a LOT of knowledge regarding assembly and a depression-level linguistic communication, such as C. You'll besides need all-encompassing knowledge on memory handling, and will need to be able to handle connections with devices and peripherals.

• Question

  Can yous requite me more data about graphics and where to start?

  

  You lot can brand the graphics yourself, and you can start someday and in whatsoever identify you want. All you need is some programming knowledge and some software to program it with. If you're not certain what to do, doing an online tutorial with such places every bit Code Academy or Khan Academy might help.

• Be sure to implement security features equally your top priority if y'all ever want your organisation to exist viable.

• Later on all evolution is washed, decide if you desire to release the code as open source, or proprietary.

• To make an operating system able to handle multiple processors, your Memory Manager must accept "locking" mechanisms in place to prevent multiple processors from accessing the same resources at the same time. The "locks" used for this will crave the presence of a scheduler to make sure that but one processor accesses a critical resource at whatsoever given time and all the others are made to wait. Yet the scheduler depends on the presence of a Retentivity Manager. This is a case of a deadlocked dependency. At that place is no standard way to solve bug like this; as a developer, you are expected to exist skilled enough to effigy out his own fashion of dealing with it.

• An operating system tin can be user friendly, too. Make sure to add together user friendly features, making these an integral part of your pattern.

• Practise not bring together the OSDev.org forums and get-go asking obvious questions. It will but issue in "Read the Manual" answers. You lot should try reading Wikipedia, and the manuals for the various tools y'all wish to use.

• Practice not start an operating system project to brainstorm learning programming. If yous don't already know C, C++, Pascal, or some other suitable language inside out, including arrow manipulation, low-level chip manipulation, fleck shifting, inline assembly language, etc., you are non set for operating-system evolution.

• If you exercise something sick-advised, like write random bytes to random I/O ports, yous volition crash your Bone, and can (in theory) fry your hardware.
