[Discuss-gnuradio] 3.7 - nothing works :)

[Ralph A. Schmid, dk5ras]

Hi,

It is not as bad as it sounds, but almost :)

With building the last "master" on a 32bit Kubuntu 12.04 none of my grc
files work. They are all with analog stuff, FM TX and RX stuff with USRP1 as
transceiver, some RTL2832 receivers.

Is it possible that old grc files do not work, although the blocks are
shown? I had a simple TX transmitter, cosinus source, NBFM TX, USRP, three
blocks, and the "old" grc file threw an error "module object has no
attribute channel_model" when running it. When I took the very same blocks
from the blocks menu and assembled the same thing together once again, it
transmitted a sine tone at 1.8GHz as it should.

Not so much luck I had with RTL2832 receivers, with WX GUI FFT and waterfall
- it simply does not work. 

I assume I am doing smth. wrong, I can't imagine that these problems are
normal :)

 My last installation came from Marcus' build script, throwing gr-baz,
grextras, gr-osmosdr and other stuff into my system. So after restoring a
backup of the old functional system (with all the stuff) at the moment I am
doing a clean uninstall of last gnuradio and the accompanying stuff, then a
complete new build of latest master, to see what is happening. The build
will take about one hour, some time to drink coffee and wait...

Ralph.
