Re: [Discuss-gnuradio] Problem with TCP Source and TCP Sink Block

[Marcus Müller]

I haven't tested that myself, but I've been told pybombs does target
Ubuntu 12.04. It will install a hell of a lot of manually built
dependencies into your prefix (which would be available for installation
from package repositories on "modern" Ubuntus), but it should work.
3.7 is the default for pybombs, by the way.

Best regards,
Marcus
