In my code I defined in this way , works fine with  Mac 10.1.3 but gives error with Mac 10.4 struct mbuf *pkt; pkt->m_pkthdr.len = 6; error: invalid use of undefined type 'struct mbuf' I heard that 'mbuf ' structure is modified but dont know how this structure is defined. Can anybody experienced this kind of problem? mbuf has been replaced by an opaque reference in Mac OS X 10.4: mbuf_t defined in kpi_mbuf.h This also probably means that you need to have 2 versions of your code...
