Re: Problem compiling libnet 1.1.2 with latest cygwin

Hello :)

Thank you all for your help : i finally compiled libnet 1.1.2 on cygwin, 
but i had to make some changes (just a little). All diffs i used and 
made are in the zip file.

So here is the story :

*1*. i first applied the icmp_redir.patch file ;)

*2*. then i applied all patch files that Ste Jones supplied (thank you!)

*3*. i tried autoconf but... it didn't work on my cygwin : so i made the 
changes manually to the configure file (see the diff) : in fact i apply 
the patch file "configure.in.diff" of Ste Jones :

-     CFLAGS="$CFLAGS -mno-cygwin -O0 -fnative-struct -DNO_SNPRINTF 
-I/usr/include/pcap"
+     CFLAGS="$CFLAGS -mno-cygwin -O0 -D_CYGWIN -DNO_SNPRINTF 
-I/usr/include/pcap"

-     LIBS="$LIBS -lws2_32"
+     LIBS="$LIBS -liphlpapi -lws2_32"

*4.* ./configure : work well :)

*5.* make caused an error while linking sebek.o (undefined reference to 
`__imp__optarg') : actually i only had to modify sebek.c to had these 
lines (also see the diff in the zip) :

#ifdef _CYGWIN
extern char *optarg;
#endif

(NB : actually i shoud have had these lines to the sample.diff file)

*6.* all linked well and make install worked fine ;)
i also tested icmp_redirect -s 1.1.1.1 -d 2.2.2.2 -g 3.3.3.3 and i saw 
in windump the redirect packet.

So i don't know what you think about all this but... as the PORTED doc 
says libnet can compile well under cygwin i think it could be better to 
apply these modification to make it work or at least explain how to ?
