I am getting a error on the python version where I execute "scons && scons check"

WARNING: Python3.11 too old (need 3.6): gps/aiogps.py will not be installed

I got python 3.11 but its telling me its too old and I need 3.6 - is there a bug in the scons check?

When I try to build executing "scons" It doesn't look like anything gets built and I get a similar message

Can I work around this to build and install?

Thanks

Thomas

Yo Thomas!

I added that over the weekend.  Grab git head, and see.  Turned out
to be non-trivial.  There are at least 6 versions of MON-HW, in three
different lengths, and then replaced my MON-RF.  gpsd now asks the
receiver to send MON-HW/RF every 4 seconds, decodes them, and output the
antenna status and jamming state to the JSON.

Notice I said "git head"?  Not 3.25.  3.25 is over a year old, and
the MON-HW patches are from this weekend.

Since jamInd looks like a superset of jamState, that is what I added.
You'll see it in gps_fix_t ->jam, and in the GPSD JSON TPV message as
"jam".
