There are already packaged sudo binaries available for Solaris, at sunfreeware for example.
Installing sudo is often unnecessary as Solaris provides natively RBAC which has most sudo has and has several useful things sudo don't.

Thanks for reply

just wanted to study sudo...so it is........... :-)

If you install the companion DVD it'll be under /opt/sfw/bin.

the server on which you are trying to install sudo package is,
Rajan had already installed sudo on the same for CA troubleshooting.

http://www.kempston.net/solaris/sudo.html is not there
Thanks.

That's the fate of most web pages, eventually. Anyway, the OP failed to achieve what (s)he wanted following the instructions there, so what's the point ?

Ya if you really want to compile sudo from source then to go the sudo website ( http://www.gratisoft.us/sudo/ ) and read what dependencies it needs and compile them from source....OR do it WAY easy and just go to sunfreeware.com and download all the dependencies and sudo itself as Solaris packages ...... if you are just trying to get experience with compiling then your question is in the wrong place...im sure the below error is from a missing dependency or a related issue
