Any tips what could cause this, Python does not like the
'U’ndefined symbol.
…/gnuradio/_atsc.so: undefined symbol: _Z14atsc_make_fpllv
$ nm _atsc.so | grep atsc_make_fpll
0004e9c0 T _Z14atsc_make_fplld
U _Z14atsc_make_fpllv
Checking the .libs objects:
$ nm atsc_fpll.o | grep atsc_make_fpll
00000cf0 T _Z14atsc_make_fplld
but:
$ nm atsc.o | grep atsc_make_fpll
U _Z14atsc_make_fpllv <— oh no!!!
SWIG missing something.
Files attached.

Usually when something like this happens, you have some versioning
problems
between interfaces. And indeed your files reveal this:
.h:
atsc_fpll_sptr atsc_make_fpll();
.cc:
atsc_fpll_sptr atsc_make_fpll(double a_initial_freq) { … }
You need to figure out which interface is the right one, and use that.
I think that “f” means float, and “v” means void, for the arguments in
the name
mangling.

Ok, changed all to atsc_make_fpll() and that works.
Ideally it would take an argument for initial_freq but I’ll sort that
out ‘later’.

In small repayment for your assistance, here’s two screenshots. First
is a local station live off the air, in 20MSps float centered on
5.75Mhz:

and the same after FPLL processing in gnuradio 2.x :

with the mixer image not yet filtered out.
