Basically, it should run on any POSIX system to which GCC >= 4.6 or a recent

for the following platforms (except resolveClassMethod: and
resolveInstanceMethod:, which are always available):

  * ARM (EABI/ELF, Apple/Mach-O)
  * ARM64 (ARM64/ELF, Apple/Mach-O)
  * MIPS (O32/ELF, EABI/ELF)
  * PowerPC (SysV/ELF, EABI/ELF, Apple/Mach-O)
  * SPARC (SysV/ELF)
  * SPARC64 (SysV/ELF)
  * x86 (SysV/ELF, Apple/Mach-O, Win32/PE)
  * x86_64 (SysV/ELF, Apple/Mach-O, Mach-O, Win64/PE)

Apple/Mach-O means both, the Apple ABI and runtime, while Mach-O means the
ObjFW runtime on Mach-O.

There are three ways you are probably reading this right now:

 * On [ObjFW](https://objfw.nil.im/)'s homepage, via Fossil
 * On [GitHub](https://github.com/ObjFW/ObjFW)
 * Via an editor or pager, by opening `README.md` from a checkout or tarball

ObjFW is developed using Fossil, so if you are reading this on GitHub or any
other place, you are most likely using a mirror.

<h1 id="what">What is ObjFW?</h1>

  ObjFW is a portable, lightweight framework for the Objective-C language. It
  enables you to write an application in Objective-C that will run on any
  [platform](PLATFORMS.md) supported by ObjFW without having to worry about
  differences between operating systems or various frameworks you would
  otherwise need if you want to be portable.

  It supports all modern Objective-C features when using Clang, but is also
  compatible with GCC ≥ 4.6 to allow maximum portability.

  ObjFW is intentionally incompatible with Foundation. This has two reasons:

   * GNUstep already provides a reimplementation of Foundation, which is only
     compatible to a certain degree. This means that a developer still needs to
     care about differences between frameworks if they want to be portable. The
     idea behind ObjFW is that a developer does not need to concern themselves
     with portablility and making sure their code works with multiple
     frameworks: Instead, if it works it ObjFW on one platform, they can
     reasonably expect it to also work with ObjFW on another platform. ObjFW
     behaving differently on different operating systems (unless inevitable
     because it is a platform-specific part, like the Windows Registry) is
     considered a bug and will be fixed.
   * Foundation predates a lot of modern Objective-C concepts. The most
     prominent one is exceptions, which are only used in Foundation as a
     replacement for `abort()`. This results in cumbersome error handling,
     especially in initializers, which in Foundation only return `nil` on error
     with no indication of what went wrong. It also means that the return of
     every `init` call needs to be checked against `nil`. But in the wild,
     nobody actually checks *each and every* return from `init` against `nil`,
     leading to bugs. ObjFW fixes this by making exceptions a first class
     citizen.

  ObjFW also comes with its own lightweight and extremely fast Objective-C
  runtime, which in real world use cases was found to be significantly faster
  than both GNU's and Apple's runtime.


<h1 id="license">License</h1>

  ObjFW is released under three licenses:

   * [QPL](LICENSE.QPL)
   * [GPLv2](LICENSE.GPLv2)
   * [GPLv3](LICENSE.GPLv3)

  The QPL allows you to use ObjFW in any open source project. Because the GPL
  does not allow using code under any other license, ObjFW is also available
  under the GPLv2 and GPLv3 to allow GPL-licensed projects to use ObjFW.

  You can pick under which of those three licenses you want to use ObjFW. If
  none of them work for you, contact me and we can find a solution.


<h1 id="releases">Releases</h1>

  Releases of ObjFW, as well as changelogs and the accompanying documentation
  can be found [here](https://objfw.nil.im/wiki?name=Releases).


<h1 id="cloning">Cloning the repository</h1>

  ObjFW is developed in a [Fossil](https://fossil-scm.org) repository, with
  automatic incremental exports to Git. This means you can either clone the
  Fossil repository or the Git repository - it does not make a huge difference.
  The main advantage of cloning the Fossil repository over cloning the Git
  repository is that you also get all the tickets, wiki pages, etc.

<h2 id="cloning-fossil">Fossil</h2>

  Clone the Fossil repository like this:

    $ fossil clone https://objfw.nil.im objfw.fossil
    $ mkdir objfw && cd objfw
    $ fossil open ../objfw.fossil

  You can then use Fossil's web interface to browse the timeline, tickets,
  wiki pages, etc.:

    $ fossil ui

  It's also possible to open the same local repository multiple times, so that
  you have multiple working directories all backed by the same local
  repository.

<h2 id="cloning-git">Git</h2>

  To clone the Git repository, use the following:

    $ git clone https://github.com/ObjFW/ObjFW


<h1 id="installation">Installation</h1>

  To install ObjFW, just run the following commands:

    $ ./configure
    $ make

    $ pacman -S mingw-w64-i686-clang mingw-w64-i686-gcc-objc

  For 64 bit binaries:

    $ pacman -S mingw-w64-x86_64-clang mingw-w64-x86_64-gcc-objc

  There is nothing wrong with installing them both, as MSYS2 has created two
  entries in your start menu: `MinGW-w64 Win32 Shell` and
  `MinGW-w64 Win64 Shell`. So if you want to build for 32 or 64 bit, you just
  start the correct shell.

  Finally, install a few more things needed to build ObjFW:

    $ pacman -S autoconf automake fossil make

<h3 id="steps-windows">Getting, building and installing ObjFW</h3>

    $ objfw-compile -o MyFirstApp MyFirstApp.m

  `objfw-compile` is a tool that allows building applications and libraries
  using ObjFW without needing a full-blown build system. If you want to use
  your own build system, you can get the necessary flags from `objfw-config`.


<h1 id="documentation">Documentation</h1>

  You can find the documentation for released versions of ObjFW
  [here](https://objfw.nil.im/docs/).

  In order to build the documentation yourself (necessary to have documentation
  for trunk / master), you need to have [Doxygen](https://www.doxygen.nl)
  installed. Once installed, you can build the documentation from the root
  directory of the repository:

    $ doxygen >/dev/null


<h1 id="bugs">Bugs and feature requests</h1>

  If you find any bugs or have feature requests, please
  [file a new bug](https://objfw.nil.im/tktnew) in the
  [bug tracker](https://objfw.nil.im/reportlist).

  Alternatively, feel free to send a mail to js@nil.im!


<h1 id="support">Support and community</h1>

  If you have any questions about ObjFW or would like to talk to other ObjFW
  users, the following venues are available:

   * The [forum](https://objfw.nil.im/forum)
   * A [Matrix](https://matrix.to/#/%23objfw:nil.im) room
   * An [IRC channel](irc://chat.freenode.net/#objfw) on Freenode (`#objfw`),
     bridged to the Matrix room above

  Please don't hesitate to join any or all of those!


<h1 id="commercial-use">Commercial use</h1>

  If for whatever reason neither the terms of the QPL nor those of the GPL work
  for you, a proprietary license for ObjFW including support is available upon
  request. Just write a mail to js@nil.im and we can find a reasonable solution
  for both parties.
