Installing winpcap and configure it with cygwin

[hisoka]

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 :

"

1. Be sure you have installed Winpcap libraries and that they are in your path by typing:
   which packet.dll which wpcap.dll

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 :

1. Copy libraries like this:
   • WpdPack\Lib\libpacket.a to cygwin\lib\
   • WpdPack\Lib\libwpcap.a to cygwin\lib\
2. Create a folder cygwin\usr\include\pcap\
3. Copy all headers from WpdPack\Include to cygwin\usr\include\winpcap\
4. Be sure you have installed Winpcap libraries and that they are in your path by typing:
   which packet.dll which wpcap.dll

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 ?

 

[justsomeguy]

Are those files actually in that directory, and are they executable?

[hisoka]

I listed all the files in this directory /cygdrive/c/WpdPack/Examples-pcap/basic_dump and this is what I got :

basic_dump.c basic_dump.dsp basic_dump.dsw basic_dump.vcproj GNUmakefile

As you can see there is NO basic_dump with .exe extension

the command : ls -l basic_dump.* gives me this :

-rwxr-x---+ 1 Administrator None 2737 Dec 23 2008 basic_dump.c
-rwxr-x---+ 1 Administrator None 4558 May 20 2005 basic_dump.dsp
-rwxr-x---+ 1 Administrator None 543 May 20 2005 basic_dump.dsw
-rwxr-x---+ 1 Administrator None 7671 Jul 24 2009 basic_dump.vcproj

these commands :
cd /cygdrive/c/WpdPack/
find . -name "basic_dump.*" give me this result:

./Examples-pcap/basic_dump/basic_dump.c
./Examples-pcap/basic_dump/basic_dump.dsp
./Examples-pcap/basic_dump/basic_dump.dsw
./Examples-pcap/basic_dump/basic_dump.vcproj
./Examples-remote/misc/basic_dump.c
./Examples-remote/misc/basic_dump.dsp
./Examples-remote/misc/basic_dump.vcproj

Moreover , I looked for an .exe file in all the folder of WpdPack but I could not find any file with .exe extension nothing special , the problem still persists

[justsomeguy]

I don't know if cygwin runs .exe files. What you have there is C source code, you're supposed to compile the executable yourself.

[hisoka]

you're supposed to compile the executable yourself

 

 

There is no executable file .

 

I tried to compile the files in basic_dump_ex using cygwin :

 

/cygdrive/c/WpdPack/Examples-pcap/basic_dump_ex

 

$make

 

but I got this :

 

cc -g -O -mno-cygwin -I ../../include -c -o basic_dump_ex.o basic_dump_ex.c

cc: error: unrecognized command line option ‘-mno-cygwin’

GNUmakefile:17: recipe for target 'basic_dump_ex.o' failed

make: *** [basic_dump_ex.o] Error 1

 

In some articles , it is stated that deleting -mno-cygwin , solve the problem . However I cannot find it this -mno-cygwin .

 

now I deleted the -mno-cygwin and I got a new error :

cc -g -O  -I ../../include -c -o basic_dump.o basic_dump.c
basic_dump.c: In function ‘main’:
basic_dump.c:27:3: warning: implicit declaration of function ‘exit’ [-Wimplicit-function-declaration]

It sounds like the C code is missing a #include directive for stdlib.h, but I don't know why it would be missing that. I suppose you could add it to the top of the source file.

[hisoka]

It sounds like the C code is missing a #include directive for stdlib.h

 

 

So I added #include "stdlib.h" and the error disappeared . However , another error emerged :

basic_dump.c:99:3: error: ‘VOID’ undeclared (first use in this function)
  (VOID)(param);

So I changed

int main ()

with

void main()

and again the error disappeared . However hundred of error emerged after that :

[hisoka]

does all these errors emerged because I changed

 int main

with

void main 

and if yes so how to correct the error :

basic_dump.c:99:3: error: ‘VOID’ undeclared (first use in this function)
  (VOID)(param);

????

[justsomeguy]

Some of those errors sound to me like the C code isn't even written correctly to begin with. e.g.:

 

basic_dump.c:25:5: error: expected expression before ‘)’ token
  if() == -1)
     ^

[hisoka]

I knew that that source code is nothing more than ing piece of and crap and the one who writes it should be ashamed from putting it there to be downloaded . It made me only lost my time and my nerves for nothing
