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
----------------------------------------------------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------------------------------------------------------
(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
-------------------------------------------------------------------------------------------------------------------------------------------------------
