Hi all,
This goes in the category of "Did anyone else need to do this?".
I'm running Ubuntu 20.04.5 LTS with GNURadio 3.8 (Maint) and UHD 4.0. I
recently upgraded UHD to 4.2. I ran into a gnuradio issue starting a
"RFNoC" flow graph with a syntax error for an unmatched ')':
Self.rfnoc_graph=ettus_rfnoc_graph_0 =
ettus.rfnoc_graph(uhd.device_addr("addr=xxx,type-n3xx")))
I was able to manually edit the generated python code to remove one of the
parentheses and see the code work.
I then upgraded gnuradio to 3.10 which had the same issue.
I then compared the "uhd_rfnoc_graph.block.yml" block files between UHD4.0
and 4.2. It's significantly different as 4.0 uses python .join to build the
argument list and UHD 4.2 uses the python module "ast" to generate the
argument list. But the final line on the 4.2 version had the syntax error
of the extra ')':
self.rfnoc_graph = ${id} =
uhd.rfnoc_graph(uhd.device_addr("${graph_args}")))
I removed one ')' then reinstalled gnuradio (make install) from the build
directory and everything seemed to work after that.
So, it seems like it is a simple syntax error. But normally something like
this (in my experience) indicates that I might have missed some
configuration step somewhere and have yet to see the other errors.
So, has anyone seen something like this?
Thanks,
Mike
