These are because you are using floating point, and some types of conversions expect a libgcc builtin, but that builtin is not available when linking against the kernel. In general, you should avoid floating point in the kernel so that we can continue to do lazy FPU spills, which enables us to context switch processes faster than we would otherwise be able to, if we had to spill the entire register state on all kernel preemptions, interrupts, or system calls. If you can, use fixed point or table lookups instead (your code will be faster, too). Alternately, you will need to provide a small static implementation for these functions on your own so that your code can find them. These are because you failed to declare a KEXT dependency on BSDKernel (com.apple.kernel.bsd) for your KEXT. Specifically, you need to list it in the "Requires" field for the property list file for you KEXT. See also: <http://developer.apple.com/documentation/Darwin/Conceptual/KEXTConcept/KEXTC...

socket calls such as socket(),connect(),accept() etc or there has APS’s such as sock_sock(), sock_bind(),sock_connect() etc… Please let me know. This email sent to tlambert@apple.com This email sent to site_archiver@lists.apple.com
