Error with USRP on make check (Mac OSX)

GNU Radio
1

Hello! I got GNU Radio functioning without the USRP. I am on Mac OSX,
and I
got this error on make check with the USRP (and only a Basic RX
daughterboard in the RXA slot)

I would apprciate any help you can give on how to get the USRP up and
running on osx

Making check in gr-usrp
Making check in src
make check-am
make check-TESTS

From 2007…nothing seemed to come of it.
Is this a case where make check fails, but the install can still work?
Please look at what I was doing (below)

Here is how I got to this: unsure what to do with the USRP (I searched
but
no one seems to tell you what to do with a new USRP… unless I’m
missing a
very obvious page), here is what I did

-Removed the install of gnu radio, plugged in and powered the USRP
(which
HAS been used before, I gander, but I really had no idea what to do)
-Re-svn’ed everything
-With the USRP powered and plugged in via USB, I bootstrapped,
./configure,
make, then make check threw the error.

I kept the USRP plugged in because I’m not sure how/when the USRP is
supposed to be configured. In my old non-USRP install, I got some errors
when using the USRP (it detected and whatnot), that I thought might be
due
to improper configuration. NOt sure now. I could try to replicate them
if
need be…

For reference, I reinstalled from scratch, without the USRP in, and got
the
same error (so obviously the USRP had no bearing).

This makes me think that this has to be an error with a newer build,
because
I didn’t have any problems make check’ing previously.

Secondarily: how does one properly use the USRP, then? Do I just run
programs, and they should work? Is there anything I need to do to make
sure
everything is configured properly? Once again: USRP, one basic rx
daughterbord in the RXA slot with an antenna plugged via a cord to the
RX-A
slot on the basic RX board

I get the same error during “make check” on the latest trunk (11460)
using OSX 10.5, so it’s probably a result of some change in the trunk
made recently. Someone will fix it sooner rather than later (but not
me; no time this week even for simple matters). I don’t think it’s an
OSX-specific problem, but might be wrong.

Look at some of the GNU radio demos for examples of how to access a
USRP from a program. - MLD

I found the error; simple fix, and I’ve checked in the changes — for
OSX and Windows only (darn required library load paths).

Thanks Michael!

I recently reorganized the USRP code to remove the (unmaintained)
in-band code and move the header files into $(include)/usrp. Chances
are the above problem stems from this, but I can’t see how just yet.
