## Compiling Qt Creator

Prerequisites:

* Qt 5.15.2 or later
* Qt WebEngine module for QtWebEngine based help viewer
* On Windows:
    * MinGW with GCC 7 or Visual Studio 2017 or later
    * Python 3.5 or later (optional, needed for the python enabled debug helper)
    * Debugging Tools for Windows (optional, for MSVC debugging support with CDB)
* On Mac OS X: latest Xcode
* On Linux: GCC 7 or later
* LLVM/Clang 10 or later (optional, LLVM/Clang 13 is recommended.
  See [instructions](#getting-llvmclang-for-the-clang-code-model) on how to
  get LLVM.
  The ClangFormat, ClangPchManager and ClangRefactoring use the LLVM C++ API.
  Since the LLVM C++ API provides no compatibility guarantee,
  if later versions don't compile we don't support that version.)
* CMake
* Ninja (recommended)

The used toolchain has to be compatible with the one Qt was compiled with.

### Linux and macOS

These instructions assume that Ninja is installed and in the `PATH`, Qt Creator
sources are located at `/path/to/qtcreator_sources`, Qt is installed in
`/path/to/Qt`, and LLVM is installed in `/path/to/llvm`.

Note that if you install Qt via the online installer, the path to Qt must
include the version number and compiler ABI. The path to the online installer
content is not enough.

See [instructions](#getting-llvmclang-for-the-clang-code-model) on how to
get LLVM.

    mkdir qtcreator_build
    cd qtcreator_build

    cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja "-DCMAKE_PREFIX_PATH=/path/to/Qt;/path/to/llvm" /path/to/qtcreator_sources
    cmake --build .

### Windows

These instructions assume that Ninja is installed and in the `PATH`, Qt Creator
sources are located at `\path\to\qtcreator_sources`, Qt is installed in
`\path\to\Qt`, and LLVM is installed in `\path\to\llvm`.

Note that if you install Qt via the online installer, the path to Qt must
include the version number and compiler ABI. The path to the online installer
content is not enough.

See [instructions](#getting-llvmclang-for-the-clang-code-model) on how to
get LLVM.

Decide which compiler to use: MinGW or Microsoft Visual Studio.

MinGW is available via the Qt online installer, for other options see
<https://wiki.qt.io/MinGW>. Run the commands below in a shell prompt that has
`<path_to_mingw>\bin` in the `PATH`.

For Microsoft Visual C++ you can use the "Build Tools for Visual Studio". Also
install the "Debugging Tools for Windows" from the Windows SDK installer. We
strongly recommend using the 64-bit version and 64-bit compilers on 64-bit
systems. Open the `x64 Native Tools Command Prompt for VS <version>` from the
start menu items that were created for Visual Studio, and run the commands
below in it.

    md qtcreator_build
    cd qtcreator_build

    cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja "-DCMAKE_PREFIX_PATH=/path/to/Qt;/path/to/llvm" \path\to\qtcreator_sources
    cmake --build .

Qt Creator can be registered as a post-mortem debugger. This can be done in the
options page or by running the tool qtcdebugger with administrative privileges
passing the command line options -register/unregister, respectively.
Alternatively, the required registry entries

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\AeDebug

can be modified using the registry editor regedt32 to contain

    qtcreator_build\bin\qtcdebugger %ld %ld

When using a self-built version of Qt Creator as post-mortem debugger, it needs
to be able to find all dependent Qt-libraries and plugins when being launched
by the system. The easiest way to do this is to create a self-contained Qt
Creator by installing it and installing its dependencies. See "Options" below
for details.

Note that unlike on Unix, you cannot overwrite executables that are running.
Thus, if you want to work on Qt Creator using Qt Creator, you need a separate
installation of it. We recommend using a separate, release-built version of Qt
Creator to work on a debug-built version of Qt Creator.

### Options

If you do not have Ninja installed and in the `PATH`, remove `-G Ninja` from
the first `cmake` call. If you want to build in release mode, change the build
type to `-DCMAKE_BUILD_TYPE=Release`. You can also build with release
optimizations but debug information with `-DCMAKE_BUILD_TYPE=RelWithDebInfo`.

You can find more options in the generated CMakeCache.txt file. For instance,
building of Qbs together with Qt Creator can be enabled with `-DBUILD_QBS=ON`.

Installation is not needed. It is however possible, using

    cmake --install . --prefix /path/to/qtcreator_install

To create a self-contained Qt Creator installation, including all dependencies
like Qt and LLVM, additionally run

    cmake --install . --prefix /path/to/qtcreator_install --component Dependencies

## Getting LLVM/Clang for the Clang Code Model

The Clang Code Model depends on the LLVM/Clang libraries. The currently
recommended LLVM/Clang version is 13.0.

### Prebuilt LLVM/Clang packages

Prebuilt packages of LLVM/Clang can be downloaded from
https://download.qt.io/development_releases/prebuilt/libclang/

This should be your preferred option because you will use the version that is
shipped together with Qt Creator (with backported/additional patches). In
addition, MinGW packages for Windows are faster due to profile-guided
optimization. If the prebuilt packages do not match your configuration, you
need to build LLVM/Clang manually.

If you use the MSVC compiler to build Qt Creator the suggested way is:
    1. Download both MSVC and MinGW packages of libclang.
    2. Use the MSVC version of libclang during the Qt Creator build.
    3. Prepend PATH variable used for the run time with the location of MinGW version of libclang.dll.
    4. Launch Qt Creator.

### Building LLVM/Clang manually

You need to install CMake in order to build LLVM/Clang.

Build LLVM/Clang by roughly following the instructions at
http://llvm.org/docs/GettingStarted.html#git-mirror:

   1. Clone LLVM/Clang and checkout a suitable branch

          git clone -b release_130-based --recursive https://code.qt.io/clang/llvm-project.git

   2. Build and install LLVM/Clang

          mkdir build
          cd build

      For Linux/macOS:

          cmake \
            -D CMAKE_BUILD_TYPE=Release \
            -D LLVM_ENABLE_RTTI=ON \
            -D LLVM_ENABLE_PROJECTS="clang;clang-tools-extra" \
            -D CMAKE_INSTALL_PREFIX=<installation location> \
            ../llvm-project/llvm
          cmake --build . --target install

      For Windows:

          cmake ^
            -G Ninja ^
            -D CMAKE_BUILD_TYPE=Release ^
            -D LLVM_ENABLE_RTTI=ON ^
            -D LLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ^
            -D CMAKE_INSTALL_PREFIX=<installation location> ^
            ..\llvm-project\llvm
          cmake --build . --target install

### Clang-Format

The ClangFormat plugin depends on the additional patch

    https://code.qt.io/cgit/clang/llvm-project.git/commit/?h=release_130-based&id=42879d1f355fde391ef46b96a659afeb4ad7814a

While the plugin builds without it, it might not be fully functional.

Note that the plugin is disabled by default.

  PREAMBLE
  The goals of the Open Font License (OFL) are to stimulate worldwide
  development of collaborative font projects, to support the font creation
  efforts of academic and linguistic communities, and to provide a free and
  open framework in which fonts may be shared and improved in partnership
  with others.

  The OFL allows the licensed fonts to be used, studied, modified and
  redistributed freely as long as they are not sold by themselves. The
  fonts, including any derivative works, can be bundled, embedded,
  redistributed and/or sold with any software provided that any reserved
  names are not used by derivative works. The fonts and derivatives,
  however, cannot be released under any other type of license. The
  requirement for fonts to remain under this license does not apply
  to any document created using the fonts or their derivatives.

  DEFINITIONS
  "Font Software" refers to the set of files released by the Copyright
  Holder(s) under this license and clearly marked as such. This may
  include source files, build scripts and documentation.

  "Reserved Font Name" refers to any names specified as such after the
  copyright statement(s).

  "Original Version" refers to the collection of Font Software components as
  distributed by the Copyright Holder(s).

  "Modified Version" refers to any derivative made by adding to, deleting,
  or substituting - in part or in whole - any of the components of the
  Original Version, by changing formats or by porting the Font Software to a
  new environment.

  "Author" refers to any designer, engineer, programmer, technical
  writer or other person who contributed to the Font Software.

  Software, subject to the following conditions:

  1) Neither the Font Software nor any of its individual components,
  in Original or Modified Versions, may be sold by itself.

  2) Original or Modified Versions of the Font Software may be bundled,
  redistributed and/or sold with any software, provided that each copy
  contains the above copyright notice and this license. These can be
  included either as stand-alone text files, human-readable headers or
  in the appropriate machine-readable metadata fields within text or
  binary files as long as those fields can be easily viewed by the user.

  3) No Modified Version of the Font Software may use the Reserved Font
  Name(s) unless explicit written permission is granted by the corresponding
  Copyright Holder. This restriction only applies to the primary font name as
  presented to the users.

  4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
  Software shall not be used to promote, endorse or advertise any
  Modified Version, except to acknowledge the contribution(s) of the
  Copyright Holder(s) and the Author(s) or with their explicit written
  permission.

  5) The Font Software, modified or unmodified, in part or in whole,
