After replacing file <sys/dlpi.h> with <sys/attdlpi.h>, I have install libpcap on SCO OpenServer successfully. Then, I want to write a small program to test it. However, when I compile the c file,which includes pcap_findalldevs,pcap_lookupdev and so on, the result is wrong as follows: # cmdpcap undefined first referenced symbol in file pcap_findalldevs mypcap.o i386ld fatal: Symbol referencing errors. No output written to mypcap So, I don't know why? Is it something I havn't config?
With discussing with a system engineer, we thought that the libpcap.a is wrong. It means that program don't recognize the lib. I don't know where is the reason, waitting for your help! sufei7099 2008-06-23 发件人： Guy Harris 发送时间： 2008-06-14 02:22:14 收件人： [email protected] 抄送： 主题： Re: [tcpdump-workers] SCO libpcap sufei7099 wrote: > I add the #incude <sys/types.h > in file.h, I.e., you changed /usr/include/sys/file.h to include <sys/types.h >?
