librosa/librosa.h:196:51: error: ‘sqrtf’ is not a member of ‘std’; did you mean ‘sqrt’?

[ljh990817]

in your "librosa/librosa.h", there use std::sqrtf(0.5f/N) , then i find here is error, remove std can success run.

Had the same issue. Ended up using sqrt() instead, but I've read that sqrtf() is supposed to be faster (but less precise).

Noticed that you can also include the header:
#include
And then replace "std::sqrtf" with simply "sqrtf"

But if would be great with an explanation what's going on here...
