Hi,
I tried to build https://cgran.org/wiki/AIS against gnuradio-3.6, and i
fails.
As 3.6 brings in a new build system, I decided to give it a go on the
AIS module. I based everything on gr-howto-write-a-block

ImportError: /usr/local/lib/python2.7/site-packages/ais/_ais_swig.so:
undefined symbol: _Z14ais_make_shiftv
Just a guess, but
In gnuradio we explicitly export the library symbols. If you arent doing
that for libgnuradioais, make sure that the visibility flag is being set
to default. You can read more here: http://gcc.gnu.org/wiki/Visibility
Hi Josh,
Actually, I've just discovered this was needed! So, yes that was it.
No it's complaining about usrp stuff, but it's another story. I don't
have a USRP, I'm using a FUNcube dongle.
BTW, should I make this package install in
lib/python2.7/site-packages/gnuradio/ais instead of
lib/python2.7/site-packages/ais
Same with the include dir: include/gnuradio/ais instead of include/ais?
I would like to be able to use gnuradio-companion, and pick up the AIS
block from the selection list, but it's not there. This might be due to
the current install dir. Any comment?
Chris
