  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions.

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version.

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

  Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

 * Calling +[dealloc] throws an exception now. If someone really calls
   [SomeClass dealloc], this should be punished and not ignored, as
   this is a serious programmer error
 * -[readLineWithEncoding:] is more fault-tolerant now and does not
   lose data when it stumbles upon invalid encoding. Instead, it allows
   recalling with the correct encoding now

==========

As forwarding needs hand-written assembly for each combination of CPU
architecture, executable format and calling convention, it is only available
for the following platforms (except resolveClassMethod: and
resolveInstanceMethod:, which are always available):

  * AMD64 (SysV/ELF, Apple/Mach-O, Mach-O, Win64/PE)
  * 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)


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's web interface
 * On [GitHub](https://github.com/ObjFW/ObjFW)
 * Via an editor or pager, by opening `README.md` from a clone 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.

  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 portability 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="installation">Installation</h1>

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

  ObjFW is released under the GNU Lesser General Public License version 3.0.


  If this license does not work for you, contact me and we can find a solution.


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

  Releases of ObjFW, as well as change logs 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

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

    cd objfw
    fossil ui





  In order to verify the signature of the currently checked out checkin, you
  can use:

    fossil artifact current | gpg --verify

  Please note that not all checkins are signed, as the signing key only resides
  on trusted systems. This means that checkins I perform on e.g. Windows are
  unsigned. However, usually it should not take long until there is another
  signed checkin. Alternatively, you can go back until the last signed checkin
  and review changes from there on.

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

  To clone the Git repository, use the following:

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

  Git commits are not signed, so if you want to check the signature of an
  individual commit, branch head or tag, please use Fossil.

<h1 id="building-from-source">Building from source</h1>

  To build ObjFW from source and install it, just run the following commands:

    ./configure
    make
    make check
    sudo make install

  In case you checked out ObjFW from the Fossil or Git repository, you need to
  run the following command first:

    ./autogen.sh

<h2 id="macos-and-ios">macOS and iOS</h2>

<h3 id="building-framework">Building as a framework</h3>

  When building for macOS or iOS, everything is built as a `.framework` by
  default if `--disable-shared` has not been specified to `./configure`. The
  frameworks will end up in `$PREFIX/Library/Frameworks`.

  To build for macOS, just follow the
  <a href="#building-from-source">regular instructions</a> above.

  To build for iOS, follow the regular instructions, but instead of
  `./configure` do something like this:

    clang="xcrun --sdk iphoneos clang"
    export OBJC="$clang -arch arm64e -arch arm64"
    export OBJCPP="$clang -arch arm64e -E"
    export IPHONEOS_DEPLOYMENT_TARGET="10.0"
    ./configure --prefix=/usr/local/ios --host=arm64-apple-darwin

  To build for the iOS simulator, follow the regular instructions, but instead
  of `./configure` use something like this:

    clang="xcrun --sdk iphonesimulator clang"
    export OBJC="$clang -arch $(uname -m)"

    export IPHONEOS_DEPLOYMENT_TARGET="10.0"
    ./configure --prefix=/usr/local/iossim --host=$(uname -m)-apple-darwin

<h3 id="framework-in-xcode">Using the macOS or iOS framework in Xcode</h3>

  To use the macOS framework in Xcode, you need to add the `.framework`s to
  your project and add the following flags to `Other C Flags`:

    -fconstant-string-class=OFConstantString -fno-constant-cfstrings

  for the one called just "MSYS" are supported, but which packages you need to
  install depends on the environment(s) you want to use. If you only want to
  target Windows 10 and newer, the CLANG64 and CLANG32 environments are the
  recommended ones.

  For CLANG64, use:

    pacman -Syu mingw-w64-clang-x86_64-clang \
                mingw-w64-clang-x86_64-fossil \
                mingw-w64-clang-x86_64-openssl

  For CLANG32, use:

    pacman -Syu mingw-w64-clang-i686-clang \
                mingw-w64-clang-i686-fossil \
                mingw-w64-clang-i686-openssl

  For CLANGARM64, use (you need to use Fossil via another environment):

    pacman -Syu mingw-w64-clang-aarch64-clang mingw-w64-clang-aarch64-openssl

  For MINGW64, use:

    pacman -Syu mingw-w64-x86_64-clang \
                mingw-w64-x86_64-fossil \
                mingw-w64-x86_64-openssl

  For MINGW32, use:

    pacman -Syu mingw-w64-i686-clang \
                mingw-w64-i686-fossil \
                mingw-w64-i686-openssl

  For UCRT64, use:

    pacman -Syu mingw-w64-ucrt-x86_64-clang \
                mingw-w64-ucrt-x86_64-fossil \
                mingw-w64-ucrt-x86_64-openssl

  When using `pacman` to install the packages, `pacman` might tell you to close
  the window. If it does so, close the window, restart MSYS2 and execute the
  `pacman` command again.

  There is nothing wrong with installing multiple environments, as MSYS2 has
  created shortcuts for each of them in your start menu. Just make sure to use
  the correct shortcut for the environment you want to use.

  Finally, install a few more things that are common between all environments:

    pacman -S autoconf automake make

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

  Start the MSYS2 using the shortcut for the environment you want to use and
  check out ObjFW:

    fossil clone https://objfw.nil.im

  You can also download a release tarball if you want. Now `cd` to the newly
  checked out repository and build and install it:

    ./autogen.sh && ./configure && make -j16 install

  If everything was successful, you can now build projects using ObjFW for
  Windows using the normal `objfw-compile` and friends.

<h2 id="nintendo">Nintendo DS, Nintendo 3DS and Wii</h2>

  Download and install [devkitPro](https://devkitpro.org/wiki/Getting_Started).

<h3 id="nintendo-ds">Nintendo DS</h3>

  Follow the normal process, but instead of `./configure` run:

    ./configure --host=arm-none-eabi --with-nds

<h3 id="nintendo-3ds">Nintendo 3DS</h3>

  Follow the normal process, but instead of `./configure` run:

    ./configure --host=arm-none-eabi --with-3ds

<h3 id="wii">Wii</h3>

  Follow the normal process, but instead of `./configure` run:

    ./configure --host=powerpc-eabi --with-wii

<h2 id="amiga">Amiga</h2>

  Install [amiga-gcc](https://github.com/bebbo/amiga-gcc). Then follow the
  normal process, but instead of `./configure` run:

    ./configure --host=m68k-amigaos


<h1 id="first-app">Writing your first application with ObjFW</h1>

  To create your first, empty application, you can use `objfw-new`:

    objfw-new --app MyFirstApp

  This creates a file `MyFirstApp.m`. The `-[applicationDidFinishLaunching:]`
  method is called as soon as ObjFW finished all initialization. Use this as
  the entry point to your own code. For example, you could add the following
  line there to create a "Hello World":

    [OFStdOut writeLine: @"Hello World!"];

  You can compile your new app using `objfw-compile`:

    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:

    make docs


<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)

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

# You can get the latest version of this script from:
# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.

# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

# The "shellcheck disable" line above the timestamp inhibits complaints
# about features and limitations of the classic Bourne shell that were
# superseded or lifted in POSIX.  However, this script identifies a wide
# variety of pre-POSIX systems that do not have POSIX shells at all, and
# even some reasonably current systems (Solaris 10 as case-in-point) still
# have a pre-POSIX /bin/sh.
