[Discuss-gnuradio] A simple question!

[Brook Lin]

Hi All,

I run gnuradio-3.1.1 on FC7. After installing gnuradio successfully, I
tested usrp_fft.py, I got GUI pop-up, and saw the spectrum at given center
frequency. However, I got some warning, see below. 
=====================================================
sudo ./usrp_fft.py 

** (python:13669): WARNING **: IPP request failed with status 1030

** (python:13669): WARNING **: IPP request failed with status 1030
gr_vmcircbuf_createfilemapping: createfilemapping is not available
======================================================
Why create file mapping is not available? Does it matter? Will it cause
other errors later?

Thanks,
Brook
