Bug 126438 – webkit-gtk-2.3.3 fails to build gstreamer support: error: member initializer 'm_complexData' does not name a non-static data member or base class

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Web Audio

[Jeremy Huddleston Sequoia]

After addressing https://bugs.webkit.org/show_bug.cgi?id=126437 to include gstfftf32.h, FFTFrameGStreamer.cpp still fails to compile with the following error when using clang 3.4 and libc++:

:info:build Source/WebCore/platform/audio/gstreamer/FFTFrameGStreamer.cpp:46:7: error: member initializer 'm_complexData' does not name a non-static data member or base class
:info:build     , m_complexData(std::make_unique<GstFFTF32Complex[]>(unpackedFFTDataSize(m_FFTSize)))
:info:build       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

gmake[1]: *** [Source/WebCore/platform/audio/gstreamer/libPlatform_la-FFTFrameGStreamer.lo] Error 1

This seems to have been an issue for quite some time but just popped up again for me now because web-audio is enabled by default in 2.3.3 (where as it was disabled by default through 2.2.3).  It's not specific to clang-3.4 or libc++.  The following were errors reported when trying to enable web audio in webkit-gtk-1.10.1.  At the time I reported these, I was told it was not yet supported and to just not force it enabled.  Unfortunately, it looks like the issue was not ever addressed before making web-audio enabled by default:

Can you grep GSTREAMER in your autotoolsconfig.h? I suspect the WTF_USE_WEBAUDIO_GSTREAMER macro is not defined.

[Jeremy Huddleston Sequoia]

Nope.  That's certainly not it:

$ grep GSTREAMER autotoolsconfig.h
#define WTF_USE_GSTREAMER 1
#define WTF_USE_WEBAUDIO_GSTREAMER 1

Seems like there's a chicken-egg problem here... The same issue is mixed between 2 bug reports.

Here in comment 0 I quote: "After addressing https://bugs.webkit.org/show_bug.cgi?id=126437"

And in https://bugs.webkit.org/show_bug.cgi?id=126437#3 : "That's a reasonable request, but I won't be able to until #126438 is resolved."

So please close one as duplicate, and try https://bugs.webkit.org/show_bug.cgi?id=126437#c2
