Hi. I'm using the Kernel framework and I'm having an issue with it: in my project I include from the framework the header Kernel/kern/thread.h. When I try to compile my source code XCode says that he is unable to find an header included by the Kernel framework: kern/kern_types.h. Actually I don't understand how this is possible, but I went to check in /usr/include and effectively inside kern/ (wich is where the incude does reference) are missing a lot of file. How can I fix this problem? Thanks to everyone.Snapshot from /usr/include/kern, where all kern/ files are missing.
