Re: [Discuss-gnuradio] Undefined symbol: wav_write_sample

[Martin Braun]

Carlos,

the functions in wavfile.cc are not publicly exported. We might want to
change that, since wavfile.h is actually publicly visible.

You can try and add the BLOCKS_API macro in wavfile.h. That will
probably fix your troubles. If so, please submit a patch & pull request.
