Good spotting, Cinaed!
judging from his initials, I'd guess gr-pwg is Paul's OOT module. Point
is that libgnuradio-pwg contains a reference to, but no implementation
of, the missing symbol, which is
_ZN2gr7trellis26viterbi_algorithm_combinedIfhEEviiiRKSt6vectorIiSaIiEES6_RKS2_IS4_SaIS4_EESA_iiiiRKS2_IT_SaISB_EENS_7digital21trellis_metric_type_tEPKSB_PT0_
or to put it more "readable" (ha, ha.) in C++ terms:
void gr::trellis::viterbi_algorithm_combined<float, unsigned char>(int, int,
int, std::vector<int, std::allocator<int> > const&, std::vector<int,
std::allocator<int> > const&, std::vector<std::vector<int, std::allocator<int>
>, std::allocator<std::vector<int, std::allocator<int> > > > const&,
std::vector<std::vector<int, std::allocator<int> >,
std::allocator<std::vector<int, std::allocator<int> > > > const&, int, int,
int, int, std::vector<float, std::allocator<float> > const&,
gr::digital::trellis_metric_type_t, float const*, unsigned char*)
or omitting standard template arguments and trying to format things:
void
gr::trellis::viterbi_algorithm_combined <float, unsigned char> (
int,
int,
int,
std::vector<int> const&,
std::vector<int> const&,
std::vector< std::vector<int> > const&,
std::vector< std::vector<int> > const&,
int,
int,
int,
int,
std::vector<float> const&,
gr::digital::trellis_metric_type_t,
float const*,
unsigned char*)
Anyway, the question is why linking doesn't look like it should.
Just to get this out of the way: Paul, what does your
lib/CMakeLists.txt's "target_link_libraries" directive look like, exactly?
Best regards,
Marcus
