You must specify the device type "psc" (using the switch -Tpsc) to eqn, troff, etc., because that's the only device supported on Athena. See details below -- this is useful knowledge as we go about trying to Makefile everything. --kcunning, 3 Jul 91 (See ditroff/ideal.man/refman, for instance) (This affects lots of formatting): from olc logs: Log Initiated for user Kevin M Cunningham (kcunning@SLINGSHOT.MIT.EDU [0]). [Mon 24-Jun-91 5:04pm] Topic: unix Question: troff can't find a file it apparently needs. I am trying to prepare formatted versions of some of the Berkeley docs in /usr/doc (I'm working on copies). I try, for example: eqn [a list of files here] | nroff -ms > refman.text and I get back: can't open file /usr/bwk/src/cprog.mac I know there's no /usr/bwk, of course. Does troff really work on Athena? Should I have attached some locker? Am I missing any special knowledge? --Kevin I'm afraid that I don't know offhand what's wrong. However, I recall that another consultant did have the necessary macro package(s) at one point. I will leave your question active so that other consultants can take a look at it. Sorry I can't be of more help. Derrick --- Comment by consultant wchuang@HEATH-BAR-CRUNCH.MIT.EDU [1]. [Mon 01-Jul-91 4:07pm] -ms should be fine, since the troff macro it's looking for is tmac.s, in /usr/lib/tmac Hello, Kevin! Try doing this: eqn -Tpsc [list of files] | nroff -ms > refman.text eqn and troff both look for directories in /usr/lib/font, according to the specific device. It appears that all devices other than "psc", are non-implemented on Athena. If you look in /usr/lib/font, you'll notice only devpsc as the only device. All other devices, -T480 (Imagen 5/480), -T202 (Mergenthaler Linotron 202), -Tcat (Graphic Systems C/A/T), and -Taps (Autologic APS-5), don't have subdirectories. Great, huh? Of course, psc isn't in the manual page either. *** Reply from user kcunning@SLINGSHOT.MIT.EDU [0]. [Wed 03-Jul-91 8:37am] Thanks, wchuang, I think that gives me what I was looking for. I have to put that particular project on the back burner, so I'll mark the question 'done' to get it out of the queue. (I just tried the -Tpsc suggestion, by the way, and it produced results, where previously plain eqn would not, so I think your fix is apropos. Note that I had to put -Tpsc after both the eqn and troff commands in the pipe...) Merci.
