Hi Tom,
GR 3.10 increased the CXX standard to c++17. Perhaps your compiler
doesn't recognize -std=c++17, but did allow -std=c++14 with GR 3.9?
My suspicion is that the following line has something to do with it:
https://github.com/gnuradio/gnuradio/blob/main/gr-utils/blocktool/core/parseheader_generic.py#L323
Cheers,
Ryan

I am trying to port an existing 3.9 OOT to 3.10. After the conversion
and edits based on the 3.10 directories,
the command to gr_modtool bind my_module fails with the error:
Unknown -std=c++xx flag used
I've greped the entire 3.10 project from its root and that string
is not in any of the project modules except in the
failed_conversions.txt file in the python bind output directory).
The only place I can see an include pointing outside the OOT directory
is in the api.h file in the project include directory:
#include <gnuradio/attributres.h>
That attributes.h file cannot be found anywhere on my system.
