Subject: ghostscript & ghostview

Jim,
	The following are my notes on compiling ghostscript 3.33 and
ghostview 1.5. They compile out of the box, but there're a couple of
things that need to be defined to get it to work on my DN3500. Anyway,
if you're collecting notes like this, I thought they might be useful.

Cheers,
Gordon

*******************************************************************
	The following refers to my experience with a DN3500, with
ANSI C and the X11-R5 library from the Michigan archive.

	Ghostscript 3.33 compiles easily out of the box, using the cc compiler. 

[ ed note -- Gordon says it's cc version 6.9.  - Jim Rees ]

	There're some statements in one of the documentation files about funny
things with Apollos, suggesting that you might have to use gcc. I actually 
had a fair amount of difficulty trying to compile with gcc, and got an
executable > 4 Mb. Using cc with the ANSI C headers (it probably won't 
work without ANSI C), it compiled effortlessly, and the executable is just
over 1 Mb. The only trick I had to use was to define _INCLUDE_BSD_SOURCE so
the compiler didn't choke on <sys/dir.h>. 

	The command line I used was:

make XCFLAGS="-D_INCLUDE_BSD_SOURCE -W0,-inlib,/lib/x11r5lib"

though others would want to inlib whatever their x11r5 shared library is
called.

	I used the provided unixansi.mak as the Makefile. I didn't follow the
provided directions about how to modify it -- I just copied it to Makefile, 
and edited it to add pdf.dev to the DEVS, so the executable can (supposedly -- 
I haven't tried it yet) read pdf files. I suspect that more substantive
changes would necessitate following their directions, though.

	It seems to work fine. 

	Ghostview-1.5 compiles about as easily. I actually didn't use their
Makefile at all, since it's a small program -- just compiled all the
routines with 

cc -O -DNON_BLOCKING_IO -DSELFILE -W0,-inlib,/usr/local/lib/x11r5lib /
	-A inlib,/usr/local/lib/x11r5lib -A cpu,3000 -c *.c

and then linked them.  Again I had to -D_INCLUDE_BSD_SOURCE to get Dir.c to 
compile, but otherwise the above command line worked fine. The cc compiler 
did a better job than gcc (smaller executable, and there were some features
that didn't work when I compiled with gcc). 

	There's one bug on my version: clicking in the
display window to zoom crashes Ghostview, with no error message. However,
changing to a different magstep works fine, and since I've never wanted to
zoom on my gview for Windows, I can probably live without it on my Apollo --
there're enough other things to fix.
