When I run gnuradio-companion with the latest gnuradio master and  
gr-osmosdr master, it segfaults. A backtrace reveals that there’s a  
problem when Python tries to load \_osmosdr\_swig. If I uninstall  
gr-osmosdr, gnuradio-companion opens normally.

GDB backtrace:

Let me know if I should open a bug report. I’m not sure if others are  
experiencing this, or there is just something weird or misconfigured on  
my system.

Ubuntu 13.04 x86\_64

Thanks,  
Sean

I just tried this with the latest git checkouts of everything  
(gnuradio, osmosdr, hackrf, rtlsdr, gr-omosdr). Here’s the enabled  
stuff in my gr-osmosdr:

## – ###################################################### – # gr-osmosdr enabled components – ###################################################### – \* Python support – \* sysmocom OsmoSDR – \* FUNcube Dongle – \* IQ File Source – \* Osmocom RTLSDR – \* RTLSDR TCP Client – \* Ettus USRP Devices – \* HackRF Jawbreaker – \* RFSPACE NetSDR

– ######################################################  
– # gr-osmosdr disabled components  
– ######################################################  
– \* Osmocom IQ Imbalance Correction  
– \* FUNcube Dongle Pro+  
– \* Osmocom MiriSDR  
– \* nuand bladeRF

Everything runs fine for me with this setup.
