Something wrong when I tried to create a out-of-tree module

GNU Radio
1

Hello all,

 My gnuradio worked fine before, but recently when I use the

command:

                                 gr_modtool newmod howto

to create a out-of-tree module, error occurs and it says,

Traceback (most recent call last):
File “/usr/local/bin/gr_modtool”, line 26, in
from gnuradio.modtool import *
File
“/usr/local/lib/python2.7/dist-packages/gnuradio/modtool/init.py”,
line 30, in
from modtool_newmod import ModToolNewModule

line 26, in
_runtime_swig = swig_import_helper()

line 22, in swig_import_helper
_mod = imp.load_module(’_runtime_swig’, fp, pathname, description)
ImportError: dynamic module does not define init function
(init_runtime_swig)

 Same thing happens when I input "from gnuradio import gr" in python

code. It never happens before. Moreover, when I reinstall

gnuradio, a module called gr-iqbal cannot be built…

  Does anybody have met such problem or have tackled it? Appreciate

your help.

Yours,
Tianqi

Your build is broken. I’ve seen this error before during development,
usually when somehow the SWIG components are outdated.
Try make clean and re-building.
