error: 'WaveHC' does not name a type. The console prints this out for almost everything in the sketch. I have a pot hooked up to analog 0 on arduino and I am using an unmodified example code from the WaveHC library. Any help would be greatly appreciated as I am very confused as to why I cannot get sample code to run.... 
Here is the example code I am using that does not compile:
Code: Select all

*
* Play files with sample rate controlled by voltage on analog pin zero.
*/

SdReader card; // This object holds the information for the card
FatVolume vol; // This holds the information for the partition on the card
FatReader root; // This holds the information for the volumes root directory
FatReader file; // This object represent the WAV file
WaveHC wave; // This is the only wave (audio) object, since we will only play one at a time
/*
* Define macro to put error messages in flash memory
*/
#define error(msg) error_P(PSTR(msg))
