Hi,
Did you try example grc flowgraph provided by gr-osmosdr[1] on both of your
machines?
[1]available in gr-osmosdr/apps folder
(https://github.com/mjmdavis/gr-osmosdr/tree/master/apps)

Subject: [Discuss-gnuradio] Flow graph using RTL-SDR or OSMOSDR source doesn't
execute on 3.6.4.1
Hi All
I have a fresh install of ubuntu 12.04.2 LTS 64 bits with gnuradio
v3.6.4.1-185-g8fda7aca.
Flow graph using RTL-SDR or OSMOSDR source doesn't execute. I get the following
log
-----------------------------------------------------------------------------------
Executing:
"/root/Other/GNU_Radio_Related/gnu_radio_examples/receiver/top_block.py"
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.005.002-65-g265daa58
Using Volk machine: avx_64_mmx_orc
gr-osmosdr 2d9e29ee (0.0.1git) gnuradio v3.6.4.1-185-g8fda7aca
built-in device types: file fcd rtl rtl_tcp uhd
-----------------------------------------------------------------------------------
Basically it does nothing after that, if I use the same Flow graph on another
machine running ubuntu 11.04 64 bits with gnuradio 3.6.2 all is good, the log
at launch is
-----------------------------------------------------------------------------------
Executing:
"/root/Other/GNU_Radio_Related/gnu_radio_examples/receiver/top_block.py"
linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.005.002-6-gf1108bd2
>>> gr_fir_ccc: using SSE
gr-osmosdr 871f0cc2 (0.0.1git) gnuradio 3.6.2
built-in device types: file fcd rtl rtl_tcp uhd
Using device #0 Generic RTL2832U SN: 77771111153705700
Found Elonics E4000 tuner
Exact sample rate is: 1000000.026491 Hz
Using Volk machine: avx_64_mmx_orc
>>> gr_fir_fff: using SSE
--------------------------------------------------------------------------------------
Both machine have rtl-sdr and gr-osmosdr installed
If for 3.6.4.1 I replace the source sink by a UHD USRP one or a Signal Source
the Flow Graph executes properly
GNURadio has been installed manually by building the source as per the wiki,
same for rtl-sdr and gr-osmosdr
(Attached the flow graph in question)
Regards
Joe
