Re: [Discuss-gnuradio] Block Path error

[ito . satosi]

Hi Marcus,

Thanks for the advice. The problem was solved.
After I built GNU Radio, I installed UHD development files. 
Therefore, the gr-uhd component was not enabled.
Again, once I built GNU Radio with the UHD development files 
installed, gr-uhd was enabled.

Best Regards,
Satoshi Ito
