I have created an xcode project as a KEXT. I am trying to specify the include folders but I'm having trouble. When I setup the include list it does not seem to pick up the .h files. I think I am doing something wrong. Here is an example of what I do: My project is in the top level directory. In the Project->Edit Project Settings->Search Paths->Header Search Paths I add the following: foo/include bar/folder_1 foo2/folder_2 That did not pickup the .h files so then I tried adding ./ to be beginning of each one but no cigar. I then tried just putting in a single . and checking the Recursive box and it finds the .hs but since there are some intended name conflicts I can't use that technique and I must specify the exact folders. Any ideas?
