Hello Josh,

Today I met this problem again. 

The gnuradio.extras can not be imported, with error of "pmt_is_null" undefined in the extras.

even though the gnuraido version I am using is v3.6.5.1.

And the grextras can not be built at all due to some error.

Hi,

I reinstalled the entire gnuradio using ./build-gnuradio -m. But when I try to import the gnuradio.extras, errors happened:

I run the sudo ldconfig after the whole installation, but the error still exists.

Btw, do I need to install the GRAS manually?
