On ubuntu 12.04.2 LTS running 3.6.4.1 , I can load the
osmosdr_source_1rtl.grc and osmosdr_source_2rtl.grc, but same as my
initial issue they don't execute, I get
----------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------------
(Interestingly if I use the RTL2832 Source from gr-baz module I can
execute the Flow Graph on 12.04.2 LTS running 3.6.4.1 , but
performance are not good at all compared to the RTLSDR Source one !! )
On the ubuntu 11.04 running 3.6.2, I can't even load the
osmosdr_source_1rtl.grc and osmosdr_source_2rtl.grc, I get the
following error

Hi,
Did you try example grc flowgraph provided by gr-osmosdr[1] on
both of your machines?

*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;

-----------------------------------------------------------------------------------
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
-----------------------------------------------------------------------------------

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)

Joe

Joe, why don't you use the build-gnuradio script. It takes care of
many details that you might have missed, and will almost certainly
result in a working system for RTLSDR when you're done.
