           Summary: [Qt] QtWebKit-2.3 tries to open non-existent qopengl.h
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P3

While trying to build QtWebKit-2.3 for an OpenGL ES2 platform running Qt 4.8.1, build of abd77b3f85375632aa313934e8eb9ae89f2bbf2e (git://gitorious.org/+qtwebkit-developers/webkit/qtwebkit-23.git) fails with many errors from Source/WebCore/platform/graphics/opengl/Extensions3DOpenGLES.h. The first error raised is:

Source/WebCore/platform/graphics/opengl/Extensions3DOpenGLES.h:35:21: error: qopengl.h: No such file or directory

Subsequent errors are simply caused by the above. The following is an excerpt of Extensions3DOpenGLES.h:

#include "Extensions3DOpenGLCommon.h"

#if PLATFORM(QT)
// Takes care of declaring the GLES extensions.
#include <qopengl.h>
#else
#include <GLES2/gl2.h>
#include <GLES2/gl2ext.h>
#endif

The #include <opengl.h> has been added with the following commit:

commit 782d2b09837c843a4afbae149e6c6b22bf1b3870

    Fix compilation with Qt 5 on MeeGo 1.2 Harmattan

    Patch by Simon Hausmann <simon.hausmann at digia.com> on 2012-09-18
    Reviewed by Jocelyn Turcotte.

    The gl2ext.h header file on the platform is outdated. Instead use the newer copy from Qt
    through implicit inclusion of qopengl.h. Since Qt's declarations are based on newer Khronos
    headers, the multi sampling extensions do have the PROC suffix, we need the same workaround
    as QNX.

    * platform/graphics/opengl/Extensions3DOpenGLES.h:

    git-svn-id: http://svn.webkit.org/repository/webkit/trunk@128877 268f45cc-cd09-0410-ab3c-d52691b4dbfc

A simple work-around is to add " && HAVE(QT5)" to "#if PLATFORM(QT)"
