Re: OOT port to 3.10 - bind error

That error message probably means that your compiler does not support the -std=c++17 flag used by GR 3.10, assuming you are using a fairly old Linux OS. Or are you using another OS/Compiler?

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.
