: USRP Error when running GNU Radio on Mac OSX leopard

GNU Radio

After installing GNU Radio 3.1.3 on leopard, here is the running error.

Traceback (most recent call last):
File “./usrp_fft.py”, line 24, in

Previous discussion included a similar question, and mentioned that it
is
related to libusb. The version of libusb installed is 0.1.12 and
libusb-compat
is deactivated. Does anyone know how to solve this?

Thank you so much.

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).
