gst-omx: #warning OMX_SKIP64BIT is not defined - this will be incompatible with the VC GPU code. [-Wcpp]

[Graham Leggett]

Hi all,

While building gstreamer-master on a Rasbian Jesse RPI3 I am getting warnings as follows, and some of the elements such as omxmpeg2videodec are silently left unbuilt:

Making all in omx
make[2]: Entering directory '/home/pi/packages/gstreamer-master/gst-omx/omx'
  CC       libgstomx_la-gstomx.lo
In file included from gstomx.h:48:0,
                 from gstomx.c:30:
/opt/vc/include/IL/OMX_Core.h:45:4: warning: #warning OMX_SKIP64BIT is not defined - this will be incompatible with the VC GPU code. [-Wcpp]
   #warning OMX_SKIP64BIT is not defined - this will be incompatible with the VC GPU code.
    ^

Adding -DOMX_SKIP64BIT to CFLAGS causes other parts of the build to fail.

The libav people discussed the issue in the following thread but it didn’t seem there was a clear solution that could be applied to gstreamer:

Can anyone confirm what you need to do to make gst-omx work on the RPI3?

Regards,
Graham

How does it fail? The warnings should not cause elements to be not
built though. Does omxh264dec work for you when building with the
warnings?

Can you report a bug about this at
