Re: SCO libpcap

["sufei7099" <sufei7099 () gmail com>]

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!

I.e., you changed /usr/include/sys/file.h to include  <sys/types.h >?

Does /usr/include/sys/param.h include  <sys/types.h > on your system?

Yes.

Presumably snort wrote out a config.log file; what are the contents of 
that file?
