Bug 66541 – [webkit-gtk] Run-time error while trying to run GtkLauncher with no video support.

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Nayan Kumar K]

We get following error while trying to launch GtkLauncher with video support disabled,

nayankk@qtc746-01:~/Sources/WebKit$ Tools/Scripts/run-launcher --gtk --debug 
Starting webkit launcher.
/home/nayankk/Sources/WebKit/WebKitBuild/Debug/Programs/GtkLauncher: symbol lookup error: /home/nayankk/Sources/WebKit/WebKitBuild/Debug/.libs/libwebkitgtk-1.0.so.0: undefined symbol: _ZN7WebCore14RenderThemeGtk25extraFullScreenStyleSheetEv

Reason for this being, in Source/WebCore/platform/gtk/RenderThemeGtk.h file, the function virtual String extraFullScreenStyleSheet(); is declared outside the ENABLE(VIDEO) guard, however it is defined in Source/WebCore/platform/gtk/RenderThemeGtk.cpp within ENABLE(VIDEO) guard. Ideally, definition of this function should lie within ENABLE(VIDEO) conditional compilation guard. 

This bug is raised to fix this error.

Run time error fix

The Fullscreen feature doesn't depend on VIDEO, ideally it's RenderThemeGtk.cpp that needs to be fixed. For the ChangeLog you can use the prepare-ChangeLog script :)

On the first look, that was my guess too. However, when I looked at how this is being implemented in other ports, (Source/WebCore/rendering/RenderThemeChromiumMac.h,  Source/WebCore/rendering/RenderThemeMac.h and Source/WebCore/rendering/RenderThemeWin.h), they seems to be implementing it the other way! Given this, which way should we follow? (Does full screen here implies full screen video?)

My emacs being the culprit here!. Will correct the patch and upload the new patch shortly!
