[GTK][STABLE] Build fails with OpenGL disabled due to missing PlatformWheelEv...

This issue has been found by the Buildroot autobuild infrastructure, the relevant part of the build log is copied below; the complete build configuration can be found at:
http://autobuild.buildroot.net/results/dd89d219efb711ecaa71a268bd6b36b06b035c80
The issue here is that OpenGL support is disabled at build time (not how the config file has both BR2_PACKAGE_LIBGTK3_X11 and BR2_PACKAGE_HAS_LIBGLES disabled, which results in -DENABLE_OPENGL=OFF and -DENABLE_GLES2=OFF being passed to CMake. This results in ENABLE_ASYNC_SCROLLING being disabled, due to this bit in Source/cmake/OptionsGTK.cmake: WEBKIT_OPTION_DEPEND(ENABLE_ASYNC_SCROLLING ENABLE_OPENGL) Then, in Source/WebCore/platform/PlatformWheelEvent.h the declaration for the isEndOfNonMomentumScroll() method is guarded with ENABLE(ASYNC_SCROLLING) but the actual implementation is guarded with PLATFORM(GTK) — resulting in the error below due to the missing declaration. WebKitGTK+ version 2.22.5 is affected, but the issue seems to be solved in trunk. ---- In file included from /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/Source/WebCore/dom/WheelEvent.h:28:0, from /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/DerivedSources/WebCore/EventHeaders.h:227, from /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/DerivedSources/WebCore/EventFactory.cpp:29, from /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/DerivedSources/WebCore/unified-sources/UnifiedSource1.cpp:3: /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/Source/WebCore/platform/PlatformWheelEvent.h:216:60: error: no 'bool WebCore::PlatformWheelEvent::isEndOfNonMomentumScroll() const' member function declared in class 'WebCore::PlatformWheelEvent' inline bool PlatformWheelEvent::isEndOfNonMomentumScroll() const ^~~~~ /home/buildroot/autobuild/run/instance-2/output/build/webkitgtk-2.22.5/Source/WebCore/platform/PlatformWheelEvent.h:221:67: error: no 'bool WebCore::PlatformWheelEvent::isTransitioningToMomentumScroll() const' member function declared in class 'WebCore::PlatformWheelEvent' inline bool PlatformWheelEvent::isTransitioningToMomentumScroll() const ^~~~~

Maybe fixed in trunk by
r238928
?

Yes, that's my guess as well. I am leaving a Buildroot compilation overnight with the same settings as the autobuilder *and*
r238928
applied to see whether that works. Thanks!

It turns out that applying only
r238928
is not enough, with it applied a different build error shows up: In file included from /home/aperez/devel/wpe/buildroot/ttt/build/webkitgtk-2.22.5/DerivedSources/WebCore/unified-sources/UnifiedSource322.cpp:8:0: /home/aperez/devel/wpe/buildroot/ttt/build/webkitgtk-2.22.5/Source/WebCore/platform/gtk/ScrollAnimatorGtk.cpp: In member function ‘virtual bool WebCore::ScrollAnimatorGtk::handleWheelEvent(const WebCore::PlatformWheelEvent&)’: /home/aperez/devel/wpe/buildroot/ttt/build/webkitgtk-2.22.5/Source/WebCore/platform/gtk/ScrollAnimatorGtk.cpp:135:15: error: ‘const class WebCore::PlatformWheelEvent’ has no member named ‘isEndOfNonMomentumScroll’ if (event.isEndOfNonMomentumScroll()) { ^~~~~~~~~~~~~~~~~~~~~~~~ /home/aperez/devel/wpe/buildroot/ttt/build/webkitgtk-2.22.5/Source/WebCore/platform/gtk/ScrollAnimatorGtk.cpp:140:15: error: ‘const class WebCore::PlatformWheelEvent’ has no member named ‘isTransitioningToMomentumScroll’ if (event.isTransitioningToMomentumScroll()) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Buildroot is shipping WebKitGTK 2.26.x, this issue is not a problem anymore.
