Unable to compile any program that depends on libnet

Hi.

Somedays ago I started to read “Building security tools…” and when I try to compile any program that depends on libnet I get errors like these:

gcc -g -c -O2 -Wall  punch.c

                 from ./punch.h:33,

I’m using OpenSuse 11.0 and the 1.1.2.1-117.1 libnet version which is the default one.

Any hint about this will be appreciate.

Cheers

It looks like you have another version of libnet includes in /usr/local/include which are interfering, see your log. How did those get there? Maybe you should remove those.

rotfl!

I didn’t see the “In file included from /usr/local/include/libnet.h” line.

As you said. It was interfering in the compile process, I guess it was copied there when I installed the latest beta of libnet from the official site.

I didn’t remove it at all, I rename it and now everything is fine, thx dude :slight_smile:
