C Programming under Tru64 UNIX

A crash course in C programming under Tru64 UNIX :-). You've got a text editor - ed(1), of course, make(1), install(1) and a C compiler - cc(1) - and you're good to go.

Don't like ED? Well, Tru64 also comes with vi and XEmacs by default, so no worries.

All you need to do now is write a Makefile:

% ed Makefile

hello: hello.o
$(CC) -o $@ $<

hello.o: hello.c
$(CC) -c -o $@ $<

rm -f hello hello.o

% make
cc -c -o hello.o hello.c
cc -o hello hello.c
% ls
Makefile hello hello.c
% hello
Hello, Tru64 UNIX!
% make clean
rm -f hello hello.o
% ls
Makefile hello.c

Is the new host name resolvable? (nslookup hostname, make sure it's in DNS or at leasts in the hosts file).

You should also check /etc/hosts and change the old hostname to the new one.
