Dear, Marcus.
Struggling for this, but still the problem is not solved.
AND ONE THING I'VE FOUND IS:
>>> import dvbt
>>> dir(dvbt)
There are no reed_solomon, reed_solomon_make, reed_solomon_sptr,
reed_solomon_sptr_swigregister and reed_solomon_swigregister. But, there
are reed_solomon_end_XX and reed_solomon_dec_XX. (XX is _make, _sptr things)
Do you think this has something to do with my probelm? I think there is no
reed_solomon_(...) module, thus I can't use gr:dvbt::reed_solomon in
MYMODULE.
Can it be solved if I modify gr-dvbt to have _make, _sptr, _swigregister
things? But, I wonder if it is a good way to modify other's sources. On the
contrary, it might be good if I can contribute to the gr-dvbt sources.
Or is it irrelevant with my problem?
Anyway, I'll try what I am thinking til some respones recevied.
Regards,
Jeon.
