Libusrp installation problem

GNU Radio
1

All -

I’m trying to set up libusrp on a G4 PowerBook under OS 10.5.1. We
installed gnuradio 3.1.1 and installed all of the supporting packages
with macports.

When I try to access the USRP I get this:

dyld: Symbol not found: _usb_error_str
Referenced from: /usr/local/lib/libusrp.0.dylib
Expected in: flat namespace

Trace/BPT

Any advice would be greatly appreciated. Or if anyone just has a set
of libusrp binaries for this system, that would be great, too. Every
new installation seems to take two full days, but this one has been
particularly brutal.

David - Sounds like libusb isn’t in the DYLD load path, wasn’t
installed correctly, or wasn’t part of the linking for libusrp. Can
you reply with [off list is probably best; we can summarize results on-
list if they’re useful]:

otool -L /usr/local/lib/libusrp.0.dylib

as well as

printenv

from the shell in which you’re running the application trying to
access the USRP. - MLD
