If this is an issue with the source code, please specify the problem,
platform, OpenCL implementation, and any additional information that will help 
us reproduce the problem:

After a fresh checkout and following the build instructions on the wiki, GCC on 
OS X 10.6.8 & Xcode 4.0 errors out due to undefined variables in the 
SimpleBufferSubBuffer example of chapter 7.

Please provide any additional information below.

Sorry for the title..

Could the problem be that clCreateSubBuffer is OpenCL 1.1, and that OS X Snow 
Leopard only implements OpenCL 1.0 (at least at release time, so 10.6.0) ?

[GoogleCodeExporter]

You need to install OS X Lion for OpenCL 1.1 support. Note that the book is 
based on OpenCL 1.1 and so you need to have a valid 1.1 implementation for many 
of the examples to work correctly.

I'm moving this to invalid as I don't think it is an issue. Please reopen if 
this is not the case.
