Gnuradio and GRC on Ubuntu 11.04

GNU Radio
1

After quite a while away, I’m trying to get gnuradio, grc, and uhd
running on my Ubuntu 11.04 machine.

The .deb packages I grab via the Ubuntu software manager install fine,
but when I try to run grc I get a crash. I see that this has been
reported as a bug a month or so ago; the error I see seems to be the
same as that bug.

Is there a fix or workaround? If not, is my best bet to build from
source?

Thanks,

John

Your best bet is to build from source:
http://gnuradio.org/redmine/wiki/gnuradio/BuildGuide is a good guide and
covers Ubuntu 11.04 quite well.

Hello,
What kind of error does the GRC give? Occurs the error while making the
GRC?Because I had an error while making the GRC and I worked around it.
I have downloaded the latest GNURadio from the site. Then I copied the
files of my own signalblocks from the old GNURadio to the new one.In the
new GNURadio I adjusted the makefile and … .i file (the dots means the
module name).
Hopefully this helps.
Regards,Nimsips. sorry for my bad English.

This was an error on execution. Building from sources with Marcus’
script solved the problem.
