Well, I am using Xcode (2.4.1), the project was initiated with the Assistant ( Kernel Extension/IOKit Driver ), generated this C++ file, and I understand the compilation process is aware of the project being C++ (where the extern "C" form is known to call for a C construct - the included pexpert.h looks like pure C ). So I understand this line is the way to call pure C from C++ - never mind. I have edited the info.plist and the HelloIOKit header file as per the tutorial. And I believe I am compiling C++ code.

First, I am not sure about where the error raised from : the call to a "C " construct, or the line before ? _______________________________________________ Do not post admin requests to the list.
