| The kext that is importing the symbol must list your library kext as a dependency via the OSBundleLibraries property.
Also, the kext that is exporting the symbols must declare itself a library by including an OSBundleCompatibleVersion property, which specifies the lower bound of a binary-compatibility range (OSBundleVersion specifies the upper bound of the range).

Now I am hitting the next hurdle of using these exported symbols in other kext. The second kext that is calling APIs of first kext fails to load saying 'Undefined symbols'. Not sure how symbols are are resolved during load time.

Did you include _kmod_info as an exported symbol? This created by Xcode for you, and needed to provide metadata about your kext to the kernel. Shantonu

I tried to export APIs through EXPORTED_SYMBOLS_FILE Xcode option. When I try to load the kext, I get following error - "kextload. kld_lookup("_kmod_info") failed for module <kextpath>"
I verified the kext using "nm" to see if the symbols are properly exported and those symbols are marked as "(__TEXT,__text) external".
