Undeclared: NI_NUMERICHOST,NI_NOFQDN,+

I bought a book entitled Unix Network Programming (W. Richard Stevens, ISBN: 0-13-490012-x) and it referenced an FTP site to download all the source code from the book: ftp://ftp.kohala.com/pub/rstevens/unpv12e.tar.gz.

Now when I commenced running the MAKE file for the drawer /libgai, it gave the following error messages during compiling:
gn_ipv46.c: NI_NUMERICHOST undeclared
gn_ipv46.c: NI_NOFQDN undeclared
gn_ipv46.c: NI_NAMEREQD undelcared
gn_ipv46.c: NI_NUMERICSERV undeclared
gn_ipv46.c: NI_DGRAM undelcared
make: *** [gn_ipv46.o] error 1 ***

I left numerous email messages to the author W. Richard Stevens, but he continues to ignore my pleas for help.  These authors...

Would you by chance know of the missing file which the MAKE file requires in order to get these variables declared?  These items appear to be #define but I could be wrong.

Thanks so much for ANY help you can provide me.

Jim.

Thanks very much ahoffmann.
I used wpe's find to recurse through my dirs (before i saw your message) and sure enough i found these definitions inside a hidden .H file. I modified Stevens book code and it work smoothly from that point on..

If you would like the points for this question please reply back with the same answer.

Thanks

BTW you wouldnt by chance know how to get my local IP address while connected to the net in Linux would you? I am using "C" and from the book it says to call gethostname() followed by gethostbyname() putting the results from gethostname into it. When i do this it ALWAYS returns back "localip.localdomain". I remember seeing this value set in my HOSTIP area under X windows but i was hoping this ip address would change to match whatever my REAL IP address was while connected to the net.  
How do i go about doing this?

find . \*.h -exec grep NI_N {} \; | grep define
then add found files to your include path (-I)

About your gethostbyname(), I'll check this question in C Language topic.
