Re: [Discuss-gnuradio] Linking gr-digital in OOT Module (Success on OSX, fails on Linux)

 Here's the result. I think the answer is "yes", but will need to read up on objdump output format.

objdump -t /usr/local/lib/libgnuradio-trellis-3.7.11git.so.0.0.0  | grep _ZN2gr7trellis26viterbi_algorithm_combinedIfhEEviiiRKSt6vectorIiSaIiEES6_RKS2_IS4_SaIS4_EESA_iiiiRKS2_IT_SaISB_EENS_7digital21trellis_metric_type_tEPKSB_PT0_

Returns:

0000000000060aa0 l     F .text 0000000000000775              _ZN2gr7trellis26viterbi_algorithm_combinedIfhEEviiiRKSt6vectorIiSaIiEES6_RKS2_IS4_SaIS4_EESA_iiiiRKS2_IT_SaISB_EENS_7digital21trellis_metric_type_tEPKSB_PT0_

If you check with objdump, is that symbol indeed in that lib ?


objdump -t /usr/local/lib/libgnuradio-trellis-3.7.11git.so.0.0.0  |
grep _ZN2gr7trellis26viterbi_algorithm_combinedIfhEEviiiRKSt6vectorIiSaIiEES6_RKS2_IS4_SaIS4_EESA_iiiiRKS2_IT_SaISB_EENS_7digital21trellis_metric_type_tEPKSB_PT0_
