Forum: GNU Radio Gr_Extras Packet_Framer problem

Hello all,

I have just installed the Extras package and trying to use the Packet
Framer.
By using a gr_vector_f -> float_to_short -> Stream_to_Blobs ->
Packet_Framer ->  GMSK Mod
i get the following error

gr_fir_fff: using SSE
Uhandler caught exception: in method
'gr_block_gw_message_type_work_args_return_value_set', argument 2 of 
type
'int'
Traceback (most recent call last):

line 53, in eval

  File
"/usr/local/lib/python2.7/dist-packages/gnuradio/extras/block_gateway.py",
line 124, in __gr_block_handle
    ) for i in self.__out_indexes],

any suggestions on how to resolve this. I also saw Josh's proposal in 
Guy's
similar problem but didn't work for me.

Thanks,

I think the work is returning something it should not in the packet
framer module.

So, I was looking at the code, and this call "line 124, in
__gr_block_handle" I think is on the different line in the most recent
master branch. Perhaps you have something out of date?

This is the latest commit 4bbb1cf01a8ac35a989bc2468fd0ccd384dede45
what do you have installed?

Hi Josh,

Thanks for the quick response.
I am in the latest commit since, I made the clone yesterday.

Hi Josh,

in case you also needed my gnuradio version, it's 3.6.2 in Ubuntu 12.04.

Thanks again,
-George
