Re: Why rfnoc_graph can not initialize in Gnuradio and CPP, (undefined reference)

[Marcus Müller]

Hi sp h,

we don't know how you're building this. You'll need to provide us with a minimal viable 
example that triggers this and we could do ourselves.

Also, you need to make sure to link against gr-ettus. It seems you're not doing this 
correctly; again, we don't know how you're building this, so it's hard to advise.

Best regards,
Marcus
