[Discuss-gnuradio] Re: Ubuntu and make check (weird results)

[Shravan Rayanchu]

Hi everyone,

It turns out there are problems with the install. I get wierd results.

I have a gentoo box and a ubuntu box both of which have gnuradio
installed. The ubuntu box however failed some make checks (my mail
below).

When I run "./usrp_spectrum_sense.py 2412M 2444M" with gentoo box, the
center frequencies are printed out fine.

However, when I do that with the ubuntu installation, I get "0.0" as
the center frequency !!

I dont get a "failed to set frequency" message. Infact, when I run the
802.11 BBN code (./bbn_80211b_rx.py -d 8 -f 2412e6 -b), I am able to
capture packets. So u.tune actually works and the frequency is set
.... I don't understand what is wrong with the installation ..

Is it because of the 'make check' failure?
