New version of ‘c2hs’ is released where the bug that prevented ‘hsndfile’ from building is fixed according to maintainer of ‘c2hs’: https://github.com/haskell/c2hs/issues/152#issuecomment-160433034 It also turns out that the package ‘hsndfile’ itself is of little use without one ‘hsndfile-vector’ package. This packages provides an instance of ‘Buffer’ type class using wrapper around ‘Vector’ data type. Without the package it's not possible to access individual audio samples.
