Qt6 OpenEmbedded/Yocto Project layer
====================================
This layer depends on:
URI: https://git.openembedded.org/openembedded-core/
and optionally:
URI: https://git.openembedded.org/meta-openembedded/
Yocto version support
---------------------
The branching of meta-qt6 layer follows [Qt branching scheme](https://wiki.qt.io/Branch_Guidelines),
that is `dev` for the development branch, `6.x` for minor stabilization branches,
`6.x.y` for the release branches and `lts-6.x.y` for commercial LTS releases.
Each Qt release is tagged either as `v6.x.y` or `v6.x.y-lts`
Following table shows the Yocto branches which are used to test each
Qt version (x) and any additional Yocto releases that are stated in
the LAYERSERIES_COMPAT (c).
| Yocto \ Qt | 6.2 | 6.1 | 6.0 |
| ---------- |:---:|:---:|:---:|
| kirkstone | x | | |
| honister | x | | |
| hardknott | c | x | x |
| gatesgarth | c | x | x |
| dunfell | x | x | x |
Commercial Qt
-------------
Qt is dual-licensed under commercial and open source licenses.
The license can be selected using the `QT_EDITION` variable. `commercial` and
`opensource` are valid values. The default value is `opensource`.
For commercial Qt users, the layer provides additional support with LTS
(Long Term Support) releases for selected Qt versions and additional
Qt modules licensed as commercial-only.
The LTS releases are available in branches named `lts-6.x`. The source code
for the LTS releases and the commercial Qt modules are only available for
commercial Qt license holders. They can only be built and used if you have
a commercial Qt license and you have set up SSH access to Qt Gerrit (see links below).
The commercial Qt modules are included in the build if the `QT_COMMERCIAL_MODULES`
variable is set to `1` and you are using a commercial edition of Qt.
QtWebEngine
-----------
QtWebEngine needs at least CMake 3.19, which is available starting from Hardknott.
For this reason QtWebEngine is not tested on older releases.
Contributing
------------
To contribute to this layer you should submit the patches for review using
[Qt Gerrit](https://codereview.qt-project.org).
