Here's a preview of some of the error log that i faced.

$ g++ -v

How should i modify the AudioFile.h to resolve this issue ?

Hi, sorry you are having problems. I created this library as a modern C++11 interface for reading audio files. It might be possible to adapt it for earlier versions of C++, but I'm not totally sure where to start. From your errors, it looks like you would need to get rid the enum classes and use regular enums, and also initialise logErrorsToConsole in the constructor..
