Re: [Discuss-gnuradio] Block Path error

[Marcus Müller]

Hi Satoshi,

it seems that when you built GNU Radio, the gr-uhd component was not  
enabled. That usually happens because the build system could not find  
UHD. So, you will have to go back and make sure UHD's development files  
can be found during the GNU Radio build.

Best regards,

Marcus
