[Discuss-gnuradio] Trouble Wrapping BPSK mapper with Python using SWIG

[Jeffrey J. Ung]

Hey everyone,

This is my first post, so allow me to introduce myself really quick.   
My name is Jeff and I'm a UCLA student working on a GNU Radio Project  
where I will attempt and hopefully succeed to implement BPSK  
modulation/demodulation on a GNU Radio with a USRP - hopefully being  
able to send something over to another GNU Radio with BPSK modulation  
and being able to demodulate it on the other end.

I've run into a problem though - I'm trying to wrap  
gr_ofdm_bpsk_mapper.cc with Python using SWIG, but when I try to run  
it in python, I get this error:


address@hidden:~/gnuradio/gnuradio-core/src/lib/general$ python  
gr_ofdm_bpsk_mapper.py

Traceback (most recent call last):
  File "gr_ofdm_bpsk_mapper.py", line 7, in <module>
    import _gr_ofdm_bpsk_mapper
ImportError:  
/home/jeffc3s/gnuradio/gnuradio-core/src/lib/general/_gr_ofdm_bpsk_mapper.so:  
undefined symbol: _ZN11omni_thread6init_tC1Ev


I've generated the .o and .so files required (I followed the SWIG  
Python module tutorial), but now I don't know what is wrong.  Anyone  
have any idea?  I sure could use the help.  Thanks in advance!!!
