I've added the getInstance function to support singleton pattern : myclass& myclass::getInstance() { static myclass instance; return instance; } However, it seems that c++11 way of initialize singleton should work in IOKit compiler, and Xcode produces the following error : This initialization requires a guard variable, which the kernel does not support The thing is, that it works for classes that does't contain IOKIt objects. Perhaps anyone encounter this issue, I haven't seen any documentation of this limitation. thanks _______________________________________________ Do not post admin requests to the list.
