When we use Buildroot's re2 package to build qt5webengine, there is an issue at link time as the qt5webengine mistakenly uses the abseil-cpp headers of its built-in copy rather than the ones of our abseil-cpp library, built as a dependency of re2. However, we build our abseil-cpp differently than the one bundled, and that causes some conflicts. Since teaching Chromium's build system to not use its own abseil-cpp headers is an adventure we'd rather not engage into, we fallback to use the bundled re2. Therefore, we drop in Config.in all dependencies that were inherited from Buildroot's re2 package. This warrants a few comments: - BR2_PACKAGE_LIBABSEIL_CPP_ARCH_SUPPORTS should be dropped because the list of architectures supported by our Buildroot abseil-cpp package may be different than the set of architectures supported by the bundled abseil-cpp in Chromium. In addition, the list of architectures in BR2_PACKAGE_QT5WEBENGINE_ARCH_SUPPORTS is also a very limited subset of BR2_PACKAGE_LIBABSEIL_CPP_ARCH_SUPPORTS, so this change will not expose the build of qt5webengine to additional architectures. - We're dropping BR2_TOOLCHAIN_GCC_AT_LEAST_8 because it was inherited from re2. The main qt5 package anyway depends on gcc >= 5.x. We will figure out thanks to the autobuilders exactly which gcc version is needed. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

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.
