I've installed the Sun online documentation utility AnswerBook on our 4/490,
and it runs fine under OpenWindows. Our users are comfortable and content with
X11R4, and don't have much interest in learning a new windowing system.
When I try to start the AnswerBook under X11R4, the Navigator window comes up,
and appears to work properly (I can search, step through Contents level-by-level,
etc.), but the Viewer window doesn't appear, and the error messages read:
Verifying environment ... finished
XView warning: invalid object (not a pointer), xv_set
XView warning: invalid object (not a pointer), xv_get
Error: CPS has not initialized or server connection failed
I'm starting AnswerBook with a shell script in an xterm window on a SparcStation 1
which is a dataless client of the 4/490:
#!/bin/csh
xhost che # add the 4/490 to list of authorized hosts which can
# create windows on the Sparcstation
set HOST = `hostname`
set ABHOME = /usr/AnswerBook/SysSoft1.1
set NEWSSERVER = \'`newsserverstr`\'
rsh che "setenv DISPLAY ${HOST}:0;\
setenv LD_LIBRARY_PATH /usr/openwin/lib:/usr/AnswerBook/SysSoft1.1/lib; \
setenv ABHOME /usr/AnswerBook/SysSoft1.1; \
setenv BOOKINFO ${ABHOME}/bookinfo; \
setenv HELPPATH ${ABHOME}/lib/help; \
setenv FONTPATH ${ABHOME}/lib/fonts; \
setenv NEWSSERVER ${NEWSSERVER}; \
${ABHOME}/bin/answerbook;"
I've gotten this far by tweaking paths and environment variables, but can't seem
to get past this hurdle. (Yes, I used the AnswerBook under OpenWindows to look
for clues in the documentation.)
Thanks in advance for any help.

Your users are going to have to run the X/News server. Changing from the MIT Xsun server to xnews is not a significant change for your users: unless you have programs that rely on server extensions other than MIT-SHM all X11R4 clients (including window managers) will run as they did with Xnews. The only perceptible difference will be a decrease in speed on machines without GX boards and an increase in speed on machines with GX boards. -- ====================================================================== Chris Flatters | cflatter@nrao.edu AIPS Scientific Programmer | ======================================================================

A friend looked into this, he said he was _fairly_ sure this was for output only, so something like ghostscript, or ralpage (a newer version of xps), or DECWindow's DPS extention could do the rendering. That is, as long as you make something listen on the NeWS port and "do the right thing". Too bad Sun didn't make an X extention to find out where to talk to for your NeWS server (it would be even better if it could tell you if the server did PostScript output only, Display PostScript, or NeWS...). > Your users are going to have to run the >X/News server.

Modulo X/NeWS bugs (some events in wrong order, XQueryBestSize returning bogus results, and who knows what else). This is not to say that X/NeWS has more bugs then MIT's X (it might, it might not), but it is one of the few servers that isn't too much like MIT's X inside; it's bugs are different. Time to learn a new set. Also last time I looked there was no shape extention (which can be used for more then just round clocks...), however I don't know about OW2.0 (I have it, I have checked a few bugs against it, but I didn't look at the output from xdpyinfo, sorry). > The only perceptible >difference will be a decrease in speed on machines without GX boards >and an increase in speed on machines with GX boards. Runs my application slower. GX, or not. I only have a 16M box and get _way_ more pageing with X/NeWS then X11R4. I think it gets poorer results on some xbench catagorys. Not that xbench is a very good server benchmark (it is a good graphic operation benchARK). It does lots of the same operation in a row, so smart servers with graphic accel's can re-use alot of the same accel request. And big servers will not see the effect of pageing, because the best of 3 runs is taken and that will leave out the time it pages, and it shouldn't page during the run (same code is executed again and again on data that should go into more or less the same pages...). -- stripes@eng.umd.edu "Security for Unix is like Josh_Osborne@Real_World,The Multitasking for MS-DOS" "The dyslexic porgramer" - Kevin Lockwood "CNN is the only nuclear capable news network..." - lbruck@eng.umd.edu (Lewis Bruck)
