Dear all, finally I cross-compiled my OOT module for running on USRP E310. Based on the instructions at "https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source";, I set the environment variable PYTHONPATH a little bit different, to point the path of the installed OOT module:
export PYTHONPATH=$LOCALPREFIX/lib/python3.5/dist-packages:$PYTHONPATH Such a way, on the target I can load my custom module in python. root@ni-e31x-316AFEA:~# python3 -c "import custom_mod" I created a flowgraph that use my OOT module, and I discovered in the newer file system for E310 python3 has not all of the needed libraries. root@ni-e31x-316AFEA:~# ./top_block.py Traceback (most recent call last): File "./top_block.py", line 12, in from gnuradio import blocks File "/home/root/localinstall/usr/lib/python3.5/dist-packages/gnuradio/blocks/__init__.py", line 38, in from .stream_to_vector_decimator import * File "/home/root/localinstall/usr/lib/python3.5/dist-packages/gnuradio/blocks/stream_to_vector_decimator.py", line 23, in from gnuradio import gr File "/home/root/localinstall/usr/lib/python3.5/dist-packages/gnuradio/gr/__init__.py", line 46, in from .top_block import * File "/home/root/localinstall/usr/lib/python3.5/dist-packages/gnuradio/gr/top_block.py", line 32, in from .hier_block2 import hier_block2 File "/home/root/localinstall/usr/lib/python3.5/dist-packages/gnuradio/gr/hier_block2.py", line 26, in import pmt File "/home/root/localinstall/usr/lib/python3.5/dist-packages/pmt/__init__.py", line 61, in from .pmt_to_python import pmt_to_python as to_python File "/home/root/localinstall/usr/lib/python3.5/dist-packages/pmt/pmt_to_python.py", line 23, in import numpy ImportError: No module named 'numpy' How could I solve the problem? I'm so close to run my OOT modules on the target... Thanks so much. Ivan Con Tiscali Mobile Smart 30 4G hai minuti illimitati, 100 SMS e 30 Giga in 4G a soli 8,99€ al mese. http://tisca.li/smart30
