Hey Jonathan,
I’m starting the process of expanding gr-Ettus to include most (if not all) of 
the existing blocks in the library. My thought was that I could use “gr_modtool 
add” to create the basic block structure inside of gr-ettus then go ahead 
creating the impl and header files to reflect the available functions in 
control.hpp (just like the DDC/DUC). 

I’m starting with the siggen block and I’ve gotten it to build but if i open a 
flowgraph that contains any RFNoC blocks I get a segfault right away with the 
message 

Warning: restarting the docstring loader (crashed while loading …

The message lists the RFNoC blocks as the problem and I’ve repeated it across 2 
systems. 

Apart from my yaml code being wrong somewhere Is there any reason this 
shouldn’t work? Do you have another suggestion for a quasi-automated process i 
could use to finally get these blocks out to the GR community?

Thanks
