[Discuss-gnuradio] Error with 2.6 Core

[address@hidden]

Hello all,

I upgrade to the 2.6 Core tar ball and now I get the following error
message when running my Python script.  I did not copy the firmware files
since I remember seeing a post that indicated that this was no longer
necessary.  What could be the problem?

address@hidden GRworking]# ./mrts_fft.py
len(rx_chan_coeffs) = 33
>>> gr_fir_ccf: using SSE
len(base_chan_coeffs) = 635
>>> gr_fir_ccc: using SSE

Thanks,

PS: Everything compiled ok even my own blocks.
