make error:undefined reference to `lpc_from_cepstrum'

[Janne-byti]

I want to know if this is just a header file loop call or is it missing some code?

I also encountered this error

same here

#208

Just as #208 you can do:
git reset --hard 3000fa24717cbb68291e5bc589da0db351b51dec
then complie, it works for me.

Removing -fvisibility=hidden from compile flags works. No need to revert to an older version.

prepend __attribute__((visibility("default"))) before the line 57 of freq.h fixed the issue
which looks like: __attribute__((visibility("default"))) float lpc_from_cepstrum(float *lpc, const float *cepstrum);

prepend attribute((visibility("default"))) before the line 57 of freq.h fixed the issue which looks like: attribute((visibility("default"))) float lpc_from_cepstrum(float *lpc, const float *cepstrum);

Bro, can I take a look at your pip list? from tensorflow.compat.v1.keras.layers import CudnnGRU is always having issues, your method really works well! thanks
