ImportError: No module named dsd_swig #52

Closed mattia-beta closed 8 years ago

mattia-beta commented 8 years ago

Hi, i've just built gr-dsd from source but the DSD demodulator is not showing inside shinysdr. Looking at the source code I've found this snippet:

try: from dsd import block_ff as dsd_block_ff _available = True except ImportError: _available = False

I think the problem is that shinysdr can't find the dsd python module. I've manually tried to import this module inside a python script but I got this error:

from dsd import block_ff as dsd_block_ff Traceback (most recent call last): File "", line 1, in File "/usr/lib/python2.7/dist-packages/dsd/init.py", line 45, in from dsd_swig import * ImportError: No module named dsd_swig

I've also checked the PYTHON_PATH running: python -c "import sys; print '\n'.join(sys.path)"

and the response is:

/usr/local/lib/python2.7/dist-packages/ShinySDR-0.0.0-py2.7.egg /usr/local/lib/python2.7/dist-packages/ephem-3.7.6.0-py2.7-linux-armv7l.egg /usr/local/lib/python2.7/dist-packages/txWS-0.9.1-py2.7.egg /usr/local/lib/python2.7/dist-packages/Twisted-16.3.2-py2.7-linux-armv7l.egg /usr/local/lib/python2.7/dist-packages/zope.interface-4.2.0-py2.7-linux-armv7l.egg /usr/lib/python2.7/dist-packages /usr/lib/python2.7 /usr/lib/python2.7/plat-arm-linux-gnueabihf /usr/lib/python2.7/lib-tk /usr/lib/python2.7/lib-old /usr/lib/python2.7/lib-dynload /usr/local/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages/PILcompat /usr/lib/python2.7/dist-packages/gtk-2.0 /usr/lib/pymodules/python2.7 /usr/lib/python2.7/dist-packages/wx-3.0-gtk2

Searching for "gr-dsd" in the filesystem:

/usr/lib/libgr-dsd.so /usr/local/lib/libgr-dsd.so

Any idea? How can I fix this error? Thank you =)

I'm afraid I don't have any advice for Python SWIG issues — and as you've already figured out, this is a problem with installing gr-dsd and not ShinySDR per se. Sorry!

(But if you figure it out, let me know — I'm thinking of putting together a “troubleshooting” section of the manual.)

@kpreid I've fixed this issue doing:

cmake . -DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib/libpyglib-2.0-python2.7.so.0

make

sudo make install

sudo ldconfig

Otherwise _dsd_swig.so is built and linked against libpython3.5m.so, leading to the following error on "import dsd": dynamic module does not define init function (init_dsd_swig)

Bye
