[Discuss-gnuradio] Issues with Using Volk machine: avx_32_mmx_orc when running interference _cancellation.grc file in LINUX

Dear discuss-gnuradio Mailing List,

I tried to run "interference_cancellation.grc" file, located on :

 /usr/local/share/gnuradio/examples/trellis/

and got the error messages result as follows :

Using Volk machine: avx_32_mmx_orc

Traceback (most recent call last):

File "tmp/int_cancellation.py", line 312, in <module> tb = int_cancellation()

File "tmp/int_cancellation.py", line 148, in __init__ self.trellis_viterbi_combined_xx_2 = trellis.viterbi_combined_cs(trellis.fsm(prefix+"gr-trellis/src/examples/fsm_files/awgn1o2_16.fsm"), 1000, -1, -1, 1, ((1-alpha)**0.5*1,(1-alpha)**0.5*1j,(1-alpha)**0.5*(-1j),(1-alpha)**0.5*(-1)), digital.TRELLIS_EUCLIDEAN)

File "/usr/local/lib/python2.7/dist-packages/gnuradio/trellis.py", line 180, in __init__ this = _trellis.new_fsm(*args)

RuntimeError: fsm::fsm(const char *name): file open error

I'm using LINUX Ubuntu 12.10 (32-bit) with Doxygen version 1.8.1.2.

I installed the GNURadio software by using "the build-gnuradio script" from http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR

The "int_cancellation.py" and "interference_cancellation.grc" files are attached on this email.

Kindly need advice to fix this error.

Thanks in advance,

Tantri
