When I put the ./configure command in my Cygwin terminal to compile a source code program , I got this error :

ERROR! Libpcap library/headers not found.
TCPDUMP/LIBPCAP public repository is a good place to fetch one
if libpcap library is installed, use the --with-libpcap-* options
to specify pathes to include and library files locations.

So , because I have windows xp as an operating system , I downloaded winpcap from this link :

WinPcap · Developer Resources

I extracted it to Cygwin directory which is C:\cygwin , then followed this link to configure winpcap with cygwin :

help installing libpcap on cygwin - Stack Overflow

In the second link , someone talked about installing some libraries :

"
because I do not have both dll , I downloaded both of them from this link :


wpcap.dll download missing file - DllDump


then put them in C:\WINDOWS\system32 .Moreover , I did exactly what second link said :


But when I followed the rest which is :




Building example using Cygwin
Open a cygwin prompt to WpdPack\Examples-pcap\basic_dump\ and execute:
basic_dump:


and tried to execute the basic_dump, basic_dump_ex and iflist commands , I got basic_dump : command not found
basic_dump_ex : command not found
iflist : command not found


So I added path C:\cygwin\WpdPack\Examples-pcap\basic_dump in windows environment variable

but to my surprise I still got command not found when I run the command above
What should I do ? or what I am missing ?
