Ok good to know! The csound api is a separate thing from csound-expression then. I thought they were two implementations of the same interface, that clears things up for me.
I got hCsound to compile (on debian), I just had to add the line: include-dirs: /usr/include/csound to hCsound.cabal. Haven't tested it beyond that though.
