qt5webengine: new package This patch is based on works [1] and [2]. With this patch, one can run the Qt5 WebEngine quicknanobrowser sample with the following options. BR2_TOOLCHAIN_BUILDROOT_LIBC="glibc" and BR2_TOOLCHAIN_BUILDROOT_CXX (Qt 5 needs a toolchain w/ wchar, NPTL, C++, dynamic library; for now it builds only with glibc) BR2_PACKAGE_LIBERATION (Qt needs at least one font) BR2_PACKAGE_QT5BASE_EXAMPLES (to install quicknanobrowser sample) BR2_PACKAGE_QT5BASE_GIF (do display gif) BR2_PACKAGE_QT5BASE_JPEG (do display jpeg) BR2_PACKAGE_QT5BASE_PNG (do display png) BR2_PACKAGE_QT5QUICKCONTROLS (needed by webengine) BR2_PACKAGE_QT5QUICKCONTROLS2 (needed by webengine) BR2_PACKAGE_QT5WEBENGINE (because it is what we want) Qt WebEngine requires an Open(E)GL-capable backend. As an example, the package rpi-userland must be enabled to build for a rpi. BR2_PACKAGE_RPI_USERLAND (to enable OpenGL ES backend) To browse for HTTPS websites, please consider adding the following options as well for SSL/TLS. BR2_PACKAGE_CA_CERT (for certificates) BR2_PACKAGE_NTPD (to sync date for certificates) Since version 5.9, chromium requires udev at runtime (see note 4). BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV (input backend) To run quicknanobrowser # cd /usr/lib/qt/examples/webengine/quicknanobrowser/ # ./quicknanobrowser https://www.buildroot.org/ Note: The chromium.inc has been generated using the following command.

The Qt WebEngine module provides a web browser engine that
makes it easy to embed content from the World Wide Web into
your Qt application.
Qt WebEngine provides C++ classes and QML types for rendering
HTML, XHTML, and SVG documents, styled using Cascading Style
Sheets (CSS) and scripted with JavaScript. HTML documents can
be made fully editable by the user through the use of the
contenteditable attribute on HTML elements.
