Problem with Qt 4.8.2 QWebkit compilation under Ubuntu

The error message is following:

In file included from /usr/include/glib-2.0/glib/gasyncqueue.h:34:0,

make: *** [sub-webkit-make_default-ordered] Error 2

the reason is because of incompatibility between Qt 4.8.2 and glib-2.0.

The solution is described in this (not commited) bug fix:

https://codereview.qt-project.org/#patch,sidebyside,25069,1,src/3rdparty/webkit/Source/JavaScriptCore/wtf/gobject/GTypedefs.h

Simply edit following file

Qt/src/3rdparty/webkit/Source/JavaScriptCore/wtf/gobject/GTypedefs.h

and modify following line

55: typedef struct _GMutex GMutex;

to

55: typedef union _GMutex GMutex;

that’s it.
