qtlocation is an ignored module, because it's not yet officially supported in Qt 6. However, it is checked out when someone clones the repo and wants to build Qt from sources. The sha of the checked-out commit for qtlocation is very old, the repo contains both qtlocation and qtpositioning sources at that revision. It is causing configuration errors, because we now have qtpositioning in its own repo, so we get duplicated targets. This commit bumps the revision of qtlocation submodule to the current dev HEAD. This will eliminate the configuration problems. Change-Id: Ia5de4d1357ea657b42465e473d5b6e02a2bb6f30 Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io>
HOW TO BUILD Qt6
Synopsis
System requirements
- CMake 3.18 or later
- Perl 5.8 or later
- Python 2.7 or later
- C++ compiler supporting the C++17 standard
It's recommended to have ninja 1.8 or later installed.
For other platform specific requirements, please see section "Setting up your machine" on: http://wiki.qt.io/Get_The_Source
Linux, Mac:
cd <path>/<source_package>
./configure -prefix $PWD/qtbase
cmake --build .
Windows:
- Open a command prompt.
- Ensure that the following tools can be found in the path:
- Supported compiler (Visual Studio 2019 or later, or MinGW-builds gcc 8.1 or later)
- Perl version 5.12 or later [http://www.activestate.com/activeperl/]
- Python version 2.7 or later [http://www.activestate.com/activepython/]
- Ruby version 1.9.3 or later [http://rubyinstaller.org/]
cd <path>\<source_package>
configure -prefix %CD%\qtbase
cmake --build .
More details follow.
Build!
Qt is built with CMake, and a typical
configure && cmake --build . build process is used.
If ninja is installed, it is automatically chosen as CMake generator.
Some relevant configure options (see configure -help):
-releaseCompile and link Qt with debugging turned off.-debugCompile and link Qt with debugging turned on.
Example for a release build:
./configure -prefix $PWD/qtbase
cmake --build .
Example for a developer build: (enables more autotests, builds debug version of libraries, ...)
./configure -developer-build
cmake --build .
See output of ./configure -help for documentation on various options to
configure.
The above examples will build whatever Qt modules have been enabled by default in the build system.
It is possible to build selected repositories with their dependencies by doing
a ninja <repo-name>/all. For example, to build only qtdeclarative,
and the modules it depends on:
./configure
ninja qtdeclarative/all
This can save a lot of time if you are only interested in a subset of Qt.
Hints
The submodule repository qtrepotools contains useful scripts for
developers and release engineers. Consider adding qtrepotools/bin
to your PATH environment variable to access them.
Building Qt from git
See http://wiki.qt.io/Building_Qt_6_from_Git and README.git for more information. See http://wiki.qt.io/Qt_6 for the reference platforms.
Documentation
After configuring and compiling Qt, building the documentation is possible by running
cmake --build . --target docs
After having built the documentation, you need to install it with the following command:
cmake --build . --target install_docs
The documentation is installed in the path specified with the
configure argument -docdir.
Information about Qt's documentation is located in qtbase/doc/README
Note: Building the documentation is only tested on desktop platforms.
