Re: [Discuss-gnuradio]: USRP Error when running GNU Radio on Mac OSX leopard

[Michael Dickens]

Hi Ying -

I know from testing that 3.2.2 and the latest trunk work under 10.5  
and libusb 0.1.12. We're working to get these working on 10.6 64-bit  
and libusb 1.0 series, but also keeping backwards compatibility with  
10.5 and 10.6 32-bit as well as libusb 0.1.12.

Is there a reason you need 3.1.3?  Could 3.2.2 work for you?  I would  
guess updating will fix your issue.  If you really need 3.1.3, then  
you'll have to do some work to fix the method  
"usrp_basic::selected_subdev(usrp_subdev_spec const&)" since  
apparently it doesn't exist in that version (at least for Darwin, but  
I suspect it just doesn't exist in that version).
