UPDATE: This works for Net::Pcap 0.16 on MSWin32. If using Net::Pcap 0.17, see Re^5: Net::Pcap installation help (and not with the library)

There are bugs in the Net::Pcap code that have not been patched that affect Windows installations. You can see this by looking at the bug report here https://rt.cpan.org/Public/Bug/Display.html?id=53292. Our own Corion fixed it and provided patches.

I've gotten Net::Pcap to build successfully on Windows XP / Strawberry 5.10, 5.12, 5.14 and also Windows 7 x64 / Strawberry 5.14, 5.16. I've used the following process:

References

--Net::Pcap

1. Get Net::Pcap from CPAN - download .tar.gz file, not with CPAN client.
2. Get patches: https://rt.cpan.org/Ticket/Display.html?id=53292
3. Edit patch files to remove the email headers.
4. Copy *.patch files into the Net-Pcap directory.
5. Apply patch files in order (0002, 0003, 0004, 0005) with:
   

     patch -p1 < FILENAME.patch
   

   NOTE: May have to 'unix2dos' the patch files if they don't work!

--WinPcap

1. Make sure WinPcap is installed - if not, install it
2. Unzip WinPcap Developers Pack http://www.winpcap.org/devel.htm in same parent directory Net::Pcap was unzipped in, e.g.,:
   

     tmp\Net-Pcap-0.16\..
     tmp\WpdPack\..
   

3. IF on x64 platform, check on the existence of the x64 libraries:
   

     dir WpdPack\lib\x64\*.a
   

4. They may not exist. If not, built them:

     pexports \Windows\system32\wpcap.dll > wpcap.def
     dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libwpcap.a --input-def wpcap.def
   
     pexports \Windows\system32\Packet.dll > Packet.def
     dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpacket.a --input-def Packet.def
   
     move libwpcap.a WpdPack\lib\x64
     move libpacket.a WpdPack\lib\x64
   

5. Start the build process:
   

     perl Makefile.PL INC=-IC:/Users/VinsWorldcom/tmp/WpdPack/Include "LI
   +BS=-LC:/Users/VinsWorldcom/tmp/WpdPack/Lib/x64 -lwpcap"
     dmake
     dmake test
   [download]

Test by creating test.pl:

use Net::Pcap qw(:functions);

@devs = pcap_findalldevs(\%devinfo, \$err);
for my $dev (@devs) {
    print "$dev : $devinfo{$dev}\n"
}
[download]

Run:

perl -Mblib test.pl
[download]

If successful output of adapters, install with:

dmake install
