The `libclang_version` variable is now updated to the current version, 15.0.0, in both "coin/provisioning/common/unix/libclang.sh" and "coin/provisioning/common/windows/libclang.ps1". The naming of the artifacts for the provided library was slightly changed from previous versions. Before, the version number would contain two integers separated by a dot. The generated artifact would be named after this version number, with the dot removed. That is, for example, for version 12.0, a release artifact would be called "libclang-release_120.*". The updated two version uses a three segments version number and, furthermore, the artifacts name do not collapse the separating dots such that a release artifact would be called "libclang-release_15.0.0.*". To support the new naming scheme, some processing was removed from both provisioning scripts. For Windows, the line removing all dots from the `libclang_version` variable was removed. For Unix, the removal of the dots in the `libclang_version` variable when expanding the variable to generate the target urls to retrieve the artifact was removed, using the bare value of the variable itself. For Unix provisioning, the artifacts for some of the platform, namely "CentOS" and "Ubuntu 22.04", are not provided anymore. "CentOS" was replaced by "Rhel8.4" on "gcc10.0", hence the target url for the redhat platform was modified based on the new name. The "Ubuntu 22.04" artifacts were not provided, such that the platform was removed. The sha1 of the target artifacts on both provisioning script was updated for all platforms.

HOW TO BUILD Qt 6
Synopsis
System requirements
- C++ compiler supporting the C++17 standard
- CMake 3.16 or newer
- Ninja 1.8 or newer
- Python 3
For more details, see also https://doc.qt.io/qt-6/build-sources.html
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)
- Python 3 ([https://www.python.org/downloads/windows/] or from Microsoft Store)
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.
