invalid use of ‘ALvoid’

Hello all,

I am  pretty new to OpenAL and C++ so I'm going through lesson 1 (the OS X
version) on DevMaster.net but I am having some trouble getting it to compile
and I'm hoping someone can give me a few pointers.

So a bit of detail.

I am using OS X (snow leopard) and have tried compiling the tutorial with
g++ and via Xcode and I'm getting the following errors which look like the
compiler is having trouble with OpenAL headers:
(compiled with g++)

In file included from main.cpp:9:

I have trawled through the forums and have seen others with similar problems
and they suggested replacing all (except the first) instances of 'ALVoid'
with 'Void' I was hoping someone could confirm that's a good way to go
before I started messing around with headers.

Any suggestions are very welcome indeed.

Many thanks

Iain Laird
