Re: [Discuss-gnuradio] I can't get my gsl to link

[Alan Corey]

Ugh, I don't like git, I'm on Sourceforge.

Is there a single command that will fetch just the correct
branch/commit/whatever?

I usually dub around until I see the green "clone or download" icon
and do one or the other.   That's what I did to get the one with the
runtime error.
