If USE_ACCELERATE_FFT is set, <gst/fft/gstfftf32.h> is not included, so WEBAUDIO_GSTREAMER builds fail with: :info:build Source/WebCore/platform/audio/gstreamer/FFTFrameGStreamer.cpp:46:38: error: use of undeclared identifier 'GstFFTF32Complex' :info:build , m_complexData(std::make_unique<GstFFTF32Complex[]>(unpackedFFTDataSize(m_FFTSize))) :info:build ^ :info:build Source/WebCore/platform/audio/gstreamer/FFTFrameGStreamer.cpp:46:55: error: expected expression :info:build , m_complexData(std::make_unique<GstFFTF32Complex[]>(unpackedFFTDataSize(m_FFTSize))) :info:build ^ :info:build mv -f Source/WebCore/platform/audio/.deps/libPlatform_la-AudioBus.Tpo Source/WebCore/platform/audio/.deps/libPlatform_la-AudioBus.Plo --- Some additional info: webkitgtk-2.3.3 $ grep -R GstFFTF32Complex * Source/WebCore/platform/audio/FFTFrame.h: std::unique_ptr<GstFFTF32Complex[]> m_complexData; Source/WebCore/platform/audio/gstreamer/FFTFrameGStreamer.cpp: , m_complexData(std::make_unique<GstFFTF32Complex[]>(unpackedFFTDataSize(m_FFTSize))) Source/WebCore/platform/audio/gstreamer/FFTFrameGStreamer.cpp: , m_complexData(std::make_unique<GstFFTF32Complex[]>(unpackedFFTDataSize(m_FFTSize))) $ grep -R GstFFTF32Complex /opt/local/include/gstreamer-1.0/ /opt/local/include/gstreamer-1.0/gst/fft/gstfftf32.h:typedef struct _GstFFTF32Complex GstFFTF32Complex; /opt/local/include/gstreamer-1.0/gst/fft/gstfftf32.h: * GstFFTF32Complex: /opt/local/include/gstreamer-1.0/gst/fft/gstfftf32.h:struct _GstFFTF32Complex /opt/local/include/gstreamer-1.0/gst/fft/gstfftf32.h: GstFFTF32Complex *freqdata); /opt/local/include/gstreamer-1.0/gst/fft/gstfftf32.h:void gst_fft_f32_inverse_fft (GstFFTF32 *self, const GstFFTF32Complex *freqdata, --- I tried to address the issue with the attached patch, but the build still fails (I'll followup with another ticket).

I think USE_ACCELERATE_FFT should be unset when webkitgtk is built on OSX. Can you please try that approach?

Hum I'm not so sure about that but I didn't really have a close look at the other bug.

Actually now I think it'd make more sense to use the FFTFrameMac implementation on OSX instead of the GStreamer backend. The main reason is that the Mac version would likely perform better (but I don't have benchmarks to prove it :))
*** Bug 126438 has been marked as a duplicate of this bug. ***
I believe this issue is obsolete based on comments in bug #126492. If this issue is still present in 2.8.1 or 2.9.1 please leave a note so we can reopen.
