Problem on gsr-aloha

Hi All

I downloaded gsr-aloha from

I installed all parts of the gsr aloha projects as defiend

1.) The PHY and DLC functions are implemented as GNU Radio signal
They are in the “./signalblocks” directory. Copy these files into
“…/gnuradio-core/src/lib/general/”. Then you must modify the
and the “” in the mentioned directory. In “general.i” the

and *.i -files and in "" the *.cc, *.h and *.i -files of 

new signal blocks must be added. After that recompile the GNU Radio
by running “make” in “…/gnuradio-core”-directory. To install the
signal blocks run “make install”.

but when I run “make” I recieved the following error warning: ‘int flush(long unsigned int*,
int, unsigned char*)’ defined but not used
make[4]: *** [gr_convolution_dec.lo] Error 1
make[4]: Leaving directory /gnur: adio-3.2.2/gnuradio-core/src/lib/general' make[3]: *** [all] Error 2 make[3]: Leaving directory /gnuradio-3.2.2/gnuradio-core/src/lib/general’
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory /gnuradio-3.2.2/gnuradio-core/src/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory /gnuradio-3.2.2/gnuradio-core/src’
make: *** [all-recursive] Error 1

2.) Install the Viterbi libraries as describe in

3.) Copy the sender control scripts (Python/sender) to the sender
computer and the receiver
control scripts (Python/receiver) to the receiver computer.

I go ahead and did step 2 and 3. but when I run ./ I
the following error


Traceback (most recent call last):
File “./”, line 7, in
from gnuradio.blks import gmsk_demod
ImportError: No module named blks

any Help please
