Cool.  Please keep us updated on your progress.

Are you compiling natively or cross compiling?  On what OS with what
tools?

I see others have used scons to build for android:

https://wiki.iotivity.org/android_build_instructions

There are also ports of scons to android:

Those should not be too difficult.  gpsd_config.h just says what features
to compile in, so you can make one by hand, as you seem to have done.

maskaudit.py can make gps_maskdump.c for you.  Or just use a current
one.

ais_json.1 is for ais, so just don't compile that part.

There are more generated files:

    'packet_names.h', 
    'timebase.h',
    'revision.h',
    'gpsd.php',

You can do an amd64 or arm native build and then grab those files.

I'm not familiar with that, we know other people have put gpsd on android,
but lack details.  I can't imagine why you could not cross compile and
use scons.  As others have done (see above).

Sounds like you are mostly there.  What is left for you?
