probleme avec winpcap sous c/c++

Question

Bonjour a tous

Je suis etudiant en informatique et je dois programmer un SNIFFER en guise de projet.

Pour cela, j'ai telechargé et installer la librairie winpcap qui donne accès aux fonctions de capture de trames.

Malheureusement, lors de la compilation de mon fichier .c, j'obtient des erreurs dans la librairie bpf.h.

Voici le resultat de ma compile

[cpp]Z:\ProjTut>gcc -o test pcap.c -lpcap

Rebonjour à tous ^^ :p

Voila une apres midi et une soirée de passer dessus toujours les deux erreurs dan sl'edition des liens:

Linking...
pcap.obj : error LNK2001: unresolved external symbol _pcap_next
pcap.obj : error LNK2001: unresolved external symbol _pcap_open_live
Debug/pcap.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

Voila ce que ca me donne :'(
Pour info je sais ou sont les librairies qui contiennent les element que Visual C++ n'arrive pas a definir, j'ai donné le repertoire a vc++ pour resoudre le probleme mais rien n'y fait.

Je pensais mettre directement les .lib .a dans le repertoire de librairie de VC++ mais je travail a l'iut (je n'ai pas acces au disk c:\ ':( )

Je suis désemparré mais je cherche encore et je vous tient au courant si je trouve ;-)

Sur ce,
A++;
