BTDT > :) Yes correct Ralph, but when I am trying to install with downgraded python (before it was up and running on 2.6 while 12.04 comes with 2.7 pre installed) seeing lot of problems, I think main issue is with auto tools, as I upgraded python to 2.7 again but did not ./bootstrap, but direct ./configure, make and sudo make install, everything seems fine now Thanks guys > > > Ralph. > > > > > > > > > > From: [email protected] > [mailto:[email protected]] On Behalf Of > Marcus M?ller > Sent: Monday, July 7, 2014 4:22 PM > To: [email protected] > Subject: Re: [Discuss-gnuradio] unable to install gnuradio-3.4.2 > > > > Hello um, nameless! > > I could imagine that a lot of tools, possibly including py_compile have > changed significantly since 3.4.2 (October 2011), although you also are > using a strongly outdated Ubuntu, so things might still match. > > The problem is that most people on here are actively developing and using > recent versions of GNU Radio with state of the art operating systems, so it > might be hard for us to reproduce your issue.
