誠心發問一些問題，麻煩大家教教我

我目前用embedded visual c++ 4.0 當作開發環境
我使用 osip和exosip(網路上的)

我編譯的出現了一些錯誤
eXosip.lib(eXutils.obj) : error LNK2019: unresolved external symbol GetIfEntry referenced in function eXosip_dns_get_local_fqdn

ARMV4Dbg/test.exe : fatal error LNK1120: 6 unresolved externals

希望有高手可以教我解決一個錯誤就好了..
因為起頭我不知道該如何下手
全部都是LINK的問題，是因為LIB錯誤嗎??
還是說??
卡再這邊卡了好久..
拜託..
