OSX gnuradio/uhd issue

dubstep · January 26, 2011, 3:32pm

Use the latest gnuradio/uhd I get an error when trying to use UHD with
my N210

Exception in static block load_modules
basic_string::_S_construct NULL not valid

and my app segfaults

if I also include a fft sink I get

RuntimeError: No buffer space available

and it hangs untill I Ctrl-C it

the code is here

macbook-chris:gnuradio updatelee$ sudo sysctl -w
net.core.rmem_max=250000000
net: class is not implemented

doesnt work on OSX

Any idea’s ?

I pushed a fix to the master, can you try it?

In short, resizing the socket buffer on macos is very bad. I had
accidentally changed the logic that blocked this behavior. Fixed.
