Compiling Qt Creator
Prerequisites:
Qt 5.11.0 or later
Qt WebEngine module for QtWebEngine based help viewer
On Windows:
ActiveState Active Perl
MinGW with g++ 5.3 or Visual Studio 2017 or later
jom
Python 3.5 or later (optional, needed for the python enabled debug helper)
On Mac OS X: latest Xcode
On Linux: g++ 5.3 or later
LLVM/Clang 8.0.0 or later (optional, needed for the Clang Code Model, Clang Tools, ClangFormat,
Clang PCH Manager and Clang Refactoring plugins, see the section
"Get LLVM/Clang for the Clang Code Model". The LLVM C++ API provides no compatibility garantee,
so if later versions don't compile we don't support that version.)
CMake (for manual builds of LLVM/Clang, and Qt Creator itself)
Ninja (optional, recommended for building with CMake)
Qbs 1.7.x (optional, sources also contain Qbs itself)
The installed toolchains have to match the one Qt was compiled with.
You can build Qt Creator with
# Optional, needed for the Clang Code Model if llvm-config is not in PATH:
export LLVM_INSTALL_DIR=/path/to/llvm (or "set" on Windows)
# Optional, disable Clang Refactoring
export QTC_DISABLE_CLANG_REFACTORING=1
# Optional, needed to let the QbsProjectManager plugin use system Qbs:
export QBS_INSTALL_DIR=/path/to/qbs
# Optional, needed for the Python enabled dumper on Windows
set PYTHON_INSTALL_DIR=C:\path\to\python
# Optional, needed to use system KSyntaxHighlighting:
set KSYNTAXHIGHLIGHTING_LIB_DIR to folder holding the KSyntaxHighlighting library
# if automatic deducing of include folder fails set KSYNTAXHIGHLIGHTING_INCLUDE_DIR as well
# both variables can also be passed as qmake variables
cd $SOURCE_DIRECTORY
qmake -r
make (or mingw32-make or nmake or jom, depending on your platform)
Installation ("make install") is not needed. It is however possible, using
make install INSTALL_ROOT=$INSTALL_DIRECTORY
Compiling Qt and Qt Creator on Windows
This section provides step by step instructions for compiling the latest
versions of Qt and Qt Creator on Windows. Alternatively, to avoid having to
compile Qt yourself, you can use one of the versions of Qt shipped with the Qt
SDK (release builds of Qt using MinGW and Visual C++ 2017 or later).
For detailed information on the supported compilers, see
https://wiki.qt.io/Building_Qt_5_from_Git .
Decide which compiler to use: MinGW or Microsoft Visual Studio. If you
plan to contribute to Qt Creator, you should compile your changes with
both compilers.
Install Git for Windows from https://git-for-windows.github.io/. If you plan to
use the MinGW compiler suite, do not choose to put git in the
default path of Windows command prompts. For more information, see
step 9.
Create a working directory under which to check out Qt and Qt Creator,
for example, c:\work. If you plan to use MinGW and Microsoft Visual
Studio simultaneously or mix different Qt versions, we recommend
creating a directory structure which reflects that. For example:
C:\work\qt5.11.0-vs15, C:\work\qt5.11.0-mingw.
Download and install Perl from https://www.activestate.com/activeperl
and check that perl.exe is added to the path. Run perl -v to verify
that the version displayed is 5.10 or later. Note that git ships
an outdated version 5.8 which cannot be used for Qt.
In the working directory, check out the respective branch of Qt from
https://code.qt.io/cgit/qt/qt5.git (we recommend the highest released version).
Check out Qt Creator (master branch or latest version, see
https://code.qt.io/cgit/qt-creator/qt-creator.git).
You should now have the directories qt and creator under your working
directory.
Install a compiler:
For a MinGW toolchain for Qt, see https://wiki.qt.io/MinGW .
For Microsoft Visual C++, install the Windows SDK and the "Debugging
Tools for Windows" from the SDK image. We strongly recommend using the
64-bit version and 64-bit compilers on 64-bit systems.
For the Visual C++ compilers, it is recommended to use the tool 'jom'.
It is a replacement for nmake that utilizes all CPU cores and thus
speeds up compilation significantly. Download it from
https://download.qt.io/official_releases/jom
and add the executable to the path.
For convenience, we recommend creating shell prompts with the correct
environment. This can be done by creating a .bat-file
(such as, \qtvars.bat) that contains the environment
variable settings.
A .bat-file for MinGW looks like:
set PATH=[qtbase]bin;\bin;\creator\bin;%PATH%
set QMAKESPEC=win32-g++
For the Visual C++ compilers, call the .bat file that sets up the
environment for the compiler (provided by the Windows SDK or the
compiler):
CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" amd64
set PATH=[qtbase]bin;\creator\bin;%PATH%
set QMAKESPEC=win32-msvc2013
You can create desktop links to the .bat files using the working
directory and specifying
%SystemRoot%\system32\cmd.exe /E:ON /V:ON /k \qtvars.bat
When using MinGW, open the shell prompt and enter:
sh.exe
That should result in a sh is not recognized as internal or external command... error. If a sh.exe is found, the compile process will fail.
You have to remove it from the path.
To make use of the Clang Code Model:
Install LLVM/Clang - see the section "Get LLVM/Clang for the Clang
Code Model".
Set the environment variable LLVM_INSTALL_DIR to the LLVM/Clang
installation directory if llvm-config is not in PATH.
Before you launch Qt Creator you may prepend the PATH with
the location of libclang.dll/.so that you want to be used.
See more info in the section "Prebuilt LLVM/Clang packages".
You are now ready to configure and build Qt and Qt Creator.
Please see https://wiki.qt.io/Building_Qt_5_from_Git for
recommended configure-options for Qt 5.
To use MinGW, open the the shell prompt and enter:
cd
configure && mingw32-make -s
cd ..\creator
qmake && mingw32-make -s
To use the Visual C++ compilers, enter:
cd
configure && jom
cd ..\creator
qmake && jom
To launch Qt Creator, enter:
qtcreator
To test the Clang-based code model, verify that backend process
bin\clangbackend.exe
launches (displaying its usage).
The library libclang.dll needs to be copied to the bin directory if
Clang cannot be found in the path.
When using Visual C++ with the "Debugging Tools for Windows" installed,
the extension library qtcreatorcdbext.dll to be loaded into the
Windows console debugger (cdb.exe) should have been built under
lib\qtcreatorcdbext32 or lib\qtcreatorcdbext64.
When using a 32 bit-build of Qt Creator with the 64 bit version of the
"Debugging Tools for Windows" the library should also be built with
a 64 bit compiler (rebuild src\libs\qtcreatorcdbext using a 64 bit
compiler).
If you are building 32 bit and running on a 64 bit
Windows, you can obtain the 64 bit versions of the extension library
and the binary win64interrupt.exe, which is required for
debugging from the repository
https://code.qt.io/cgit/qt-creator/binary-artifacts.git/tree .
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
\qt-creator\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 provide them for Qt 5 is to run the tool windeployqt:
windeployqt -quick -qmldir share\qtcreator\welcomescreen -qmldir src\plugins\qmlprofiler bin\qtcreator.exe lib\qtcreator lib\qtcreator\plugins
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 build of it. We recommend using a separate, release-built version
of Qt and Qt Creator to work on a debug-built version of Qt and Qt Creator
or using shadow builds.
Get LLVM/Clang for the Clang Code Model
The Clang Code Model depends on the LLVM/Clang libraries. The currently
supported LLVM/Clang version is 8.0.
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:
Clone LLVM/Clang and checkout a suitable branch
git clone -b release_80-based --recursive https://code.qt.io/clang/llvm-project.git
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= \
../llvm-project/llvm
cmake --build . --target install
For Windows:
cmake ^
-G "NMake Makefiles JOM" ^
-D CMAKE_BUILD_TYPE=Release ^
-D LLVM_ENABLE_RTTI=ON ^
-D LLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ^
-D CMAKE_INSTALL_PREFIX= ^
..\llvm-project\llvm
cmake --build . --target install
Clang-Format
The ClangFormat plugin depends on the additional patch
https://code.qt.io/cgit/clang/clang.git/commit/?h=release_80-based&id=fa1b9053729ec6a4425a44ec5502dd388928274a
While the plugin builds without it, it will be disabled on start with an error message.
Note that the plugin is disabled by default.
Building Qt Creator with CMake
Qt Creator can also be built with CMake. The main Qt Creator dependencies, Qt and LLVM/Clang, both
offer CMake find packages, which reduce the steps of configuring Qt Creator to a minimum.
Configure and build Qt Creator:
mkdir build
cd build
For Linux/macOS:
cmake \
-G Ninja \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_PREFIX_PATH=~/Qt/5.12.5/gcc_64;~/llvm \
../qt-creator
cmake --build .
For Windows:
cmake ^
-G Ninja ^
-D CMAKE_BUILD_TYPE=Release ^
-D CMAKE_PREFIX_PATH=c:\Qt\5.12.5\msvc2017_64;c:\llvm ^
..\qt-creator
cmake --build .
