Hi all,
I installed the gr-ettus modules and RFNoC version of UHD (
UHD_003.010.rfnoc-316-gb7546712), but when I tried to run the sample GRC,
it runs into this error:
AttributeError: 'module' object has no attribute 'device3'
Can someone point out where I may make a mistake? Thanks in advance!

source->stop(),
the file still keeps growing larger.
I am confused by these two issues, thanks in advance for anyone pointing
out the problem.

, the same error output
occurs. Therefore, the problem is about the new make function, which I used
from Revision 338cfae6. I just copied and pasted the three files of the
revision, then make and make install.
Thanks,

Hi,
By adding ${UHD_LIBRARIES}, the problem is solved :)
Thanks,

block doesn't have this function.
So I may need to write a custom C OOT block. Can you give me a clue on how
to do this? Because I didn't find example specifically for usrp on the
website.
Thanks a lot.
