Using Cygwin (but I highly suggest to use MinGW)

It compiles and link with the examples, and i also manage to use it for the arping port.

[edit]

Requirements

First you need to setup Winpcap on Cygwin. This can be easily done using this article: How
to install Winpcap / Libpcap under Cygwin

Then you will have to download the version you want of Libnet

[edit]

Compiling Libnet 1.1.2.1

You need this patch to
compile libnet under cygwin. See README file for more details.

You can also download compiled
binaries.

[edit]

Compiling Libnet 1.1.3

You need this patch to
compile libnet under cygwin. See README file for more details.

You can also download compiled
binaries.

For example, here is my Cygwin
console output used to apply this patch and compile Libnet.

To compile a sample or a file alone (for example synflood.c [show] ), i used :

gcc -g -Wall -mno-cygwin -DNO_SNPRINTF -D_LIBNETCYGWIN -I /usr/include/pcap -I /usr/include/libnet/win32 -c synflood.c
gcc -g -Wall -mno-cygwin -o synflood.exe synflood.o -lnet -lwpcap -lpacket -lws2_32 -liphlpapi

!!! WARNING !!!

make install copies to /usr/include/ the win32 folder... You must move it into /usr/include/libnet folder.

/usr/include/libnet
¦   libnet-asn1.h
¦   libnet-functions.h
¦   libnet-headers.h
¦   libnet-macros.h
¦   libnet-structures.h
¦   libnet-types.h
¦
+---win32
        getopt.h
        in_systm.h
        libnet.h

Also, you can remove the -DNO_SNPRINTF in the compilation line for recent version of Cygwin / Mingw. Edit /usr/bin/libnet-config and remove it here:

libnet_defines="-D_LIBNETCYGWIN"
libnet_cflags="-mno-cygwin -I/usr/include/pcap -I /usr/include/libnet/win32"
libnet_libs="-lws2_32 -liphlpapi -lnet"

The compilation line becomes:

gcc -g -Wall -mno-cygwin -D_LIBNETCYGWIN -I /usr/include/pcap -I /usr/include/libnet/win32 -c synflood.c
gcc -g -Wall -mno-cygwin -o synflood.exe synflood.o -lnet -lwpcap -lpacket -lws2_32 -liphlpapi

All these modifications should have been included automatically through the configuration process but i did not have time to recheck all the diffs again.

Using MinGW

[edit]

Requirements

First install MinGW
Setup Winpcap. This can be easily done using this article: How
to install Winpcap / Libpcap under Cygwin
Download the version you want of Libnet
