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. ( echo 'CHROMIUM_LICENSE_FILES = \' && cd output/build/qt5webengine-5.9.1/ && \ find "src/3rdparty/chromium/" -type f -iname "*LICENSE*" -o -iname "*COPYING*" -o -iname "*GPL*" | \ sed -e '/\.asm$/d' \ -e '/\.h$/d' \ -e '/\.c$/d' \ -e '/\.cc$/d' \ -e '/\.cpp$/d' \ -e '/\.pyc\?$/d' \ -e '/\.pl$/d' \ -e '/\.sha1$/d' \ -e '/\.patch$/d' \ -e '/licensecheck/d' \ -e 's,^,\t,' \ -e 's,$, \\,' | \ sort && \ echo '' ) >package/qt5/qt5webengine/chromium.inc Note 2: Since 5.9.1, the chromium's copy of opus fails with neon [3]. Qt WebEngine can uses buildroot ffmpeg copy which compiles fine (using qmake flag WEBENGINE_CONFIG+=use_system_ffmpeg). It implies selecting the following options.

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.
