Building VNC 3.3.3 on HP-UX 10.20

[Stephen Walton]

In the interest of giving something back:  Here is a brief set of
instructions based on careful notes I kept.  This will go into the archive
for the future, I hope.

My system:  HP-UX 10.20, pretty up to date on patches, HP ANSI C.  This
compiler comes with the X developer's package.  In particular, Imake gets
put in /opt/imake and the Xaw and Xmu header files and libraries in
/usr/contrib/X11R6.

A caution:  HP ANSI C uses the value of the CCOPTS environment variable in
addition to any flags specified in the Makefile, and ld(1) uses the value
of the LDOPTS variable similarly.  So you should probably make sure that
you have a vanilla setup by checking (as appropriate) $HOME/.profile,
$HOME/.kshrc, $HOME/.login, $HOME/.cshrc, /etc/profile, /etc/csh.cshrc
(tcsh only), and /etc/csh.login to make sure you or your sysadmin isn't
setting these values for you. Simply unsetting them at the command line
before typing "make" won't work, because make uses the system(2) call to
run the compiler & linker, and thus the startup files will get reread.  
If your sysadmin has these set in the system files, try to get her to
remove them.

Unpack the archive, cd vnc_unixsrc and apply the two HP-UX patches on the
Web site.  I find they still apply to 3.3.3 without changes required.

As I noted above, HP's imake is in /opt/imake, so make sure /opt/imake/bin
is on your path (it should be as the installation puts this directory in
/etc/PATH).  cd into the vnc_unixsrc directory and type "xmkmf; make
World".  This only takes a few minutes even on my old workstation.  You
will find that vncviewer doesn't get built because of the "missing" Xaw
and Xmu files. I added the following lines to vncviewer/Imakefile which I
submit as a new patch:

#if defined(HPArchitecture)
INCLUDES = -I/usr/include/X11R6 -I/usr/contrib/X11R6/include \
	-I../include -I.
#else
INCLUDES = -I../include -I.
#endif

following which I did 

% xmkmf; setenv LDOPTS -L/usr/contrib/X11R6/lib; make all

in the vncviewer directory.  I was unable to find a clean way to add this
-L option to the vncviewer Imakefile.

"make World" completes in the Xvnc directory with no trouble and with no
CCOPTS or LDOPTS settings required.

Perl on HP's:  /usr/contrib/bin/perl is the one distributed with HP-UX
10.20 but it is pretty old (version 4.0).  You should plan on putting the
latest version on your system and editing your local copy of vncserver
accordingly.  I changed the first line to

#!/usr/bin/env perl

which should find the same copy of perl as "which perl" prints on pretty
much all Unix systems.

So, that's how I did it.  I hope it helps someone else.
