I'm getting a bunch of unresolved symbols when I try to load my kext:

kextload: notice: extension build/Debug/mykext.kext has debug properties set

kextload: extension build/Debug/mykext.kext appears to be loadable

kld(): Undefined symbols:

__Z11iflt_attachP7__ifnetPK10iff_filterPP14__ifnet_filter

__Z11iflt_detachP14__ifnet_filter

__Z13mbuf_tag_findP6__mbufjtPmPPv

__Z16mbuf_tag_id_findPKcPj

__Z17mbuf_tag_allocateP6__mbufjtmjPPv

__Z8mbuf_lenP6__mbuf

__Z9mbuf_dataP6__mbuf

__Z9mbuf_nextP6__mbuf

Translated as:

iflt_attach(__ifnet*, iff_filter const*, __ifnet_filter**)

iflt_detach(__ifnet_filter*)

mbuf_tag_find(__mbuf*, unsigned int, unsigned short, unsigned long*, void**)

mbuf_tag_id_find(char const*, unsigned int*)

mbuf_tag_allocate(__mbuf*, unsigned int, unsigned short, unsigned long, unsigned int, void**)

mbuf_len(__mbuf*)

mbuf_data(__mbuf*)

mbuf_next(__mbuf*)

My OSBundleLibraries are as follows:

<key>OSBundleLibraries</key>

<dict>

<key>com.apple.kpi.bsd</key>

<key>com.apple.kpi.iokit</key>

<key>com.apple.kpi.libkern</key>

<key>com.apple.kpi.mach</key>

</dict>

Which I thought would be correct given the instructions here:

http://developer.apple.com/documentation/Darwin/Conceptual/NKEConceptual/about/chapter_2_section_1.html

I'm building against the 10.4 SDK on 10.5.4.

Any idea what is going on?

Thanks,

Doug
