X Psroff 2.0 Trouble Shooting.... 2.2 90/10/30
X
X (psroff 1.0 users can use this to a certain extent)
X
XThese are some pointers to possible solutions to problems with psroff.
XAfter correcting a problem, you usually need to do:
X
X make all
X su root
X make install
X make installwidths
X
XThis is assuming that you got clean compiles (you should be able
Xto fix your own compile problems).
X
XIMPORTANT NOTE: MANY configuration difficulties can be detected
Xby "make check". If you do encounter a problem, I suggest that
Xyou run "make check" first and correct any "ERROR"'s it reports
Xthat apply to the configuration (driver/printer) you wish to use.
XIf you encounter problems you cannot solve and wish to ask me for
Xhelp, I will want you to send me a copy of "make check"'s output....
X
XDefinitions:
X - LIBDIR - default /usr/lib/troff2 (config option in Makefile)
X LJ drivers pick up font files from LIBDIR/lib/lj.
X - FONTDIR - by default "/usr/lib/font" (config option in Makefile).
X Must be /usr/lib/font unless you have a '-F' troff, see
X "width option" below.
X - "width tables". psroff's install generates CAT compatible width
X tables and installs them into $FONTDIR/<widthname>/ft*, where
X "widthname" is a token denoting the "set" of widths. Postscript
X printers (or ditroff driving postscript) use ps. These are
X the only widths I distribute directly. The Makefile will
X install widths into widthname "lj" if you have laserjet fonts
X installed in the right place.
X - "width option", most troff's support a way of telling it where
X to look for the width tables. Some support -T<widthname> (Xenix
X f'r instance). Others (Sun specifically, probably other BSD
X derivitives) need "-F<directory>/<widthname>/ftXX". Check your
X man pages for troff. This is should be specified by "trofftype"
X in lib/psroff.lib.S. If you have a "-T" version of troff,
X FONTDIR *must* be /usr/lib/font. If your troff supports neither
X -T or -F (some real old versions of Xenix, V7 perchance), you
X will have to install the width tables in FONTDIR directly and
X specify trofftype as "". Which will also mean that you can
X only support one set of width tables. (Unless you make binary
X patches to your troff)
X - "psroff debug" - rerun the psroff command, additionally specifying
X "-F" in the command line. This permit's troff's stderr to be
X seen. Correct any problems that it tells you about. (eg:
X "width option"). If you see lines of the form:
X M<string>
X These are back-end directives and they're supposed to be
X there during psroff debug - ignore them.
X - HEADERSIZE: some troff's need an a.out.h header on the front
X of the width table files. HEADERSIZE (defs.h) allows you to
X specify an arbitrary number of bytes on the front of the table
X in the width file. Check /usr/lib/font/ftR (should be part
X of your original troff installation. Is ftR 224 bytes long?
X If so, HEADERSIZE should be zero. If not (eg: Ultrix, possibly
X older BSD's, some older Xenix, V7), you will have to specify
X HEADERSIZE. Ultrix wants 32. (should be the size of an
X a.out header structure - od -c may give you some hints).
X Another way to tell is to run "file" on /usr/lib/font/ftR.
X Does it say "data"? Then it probably needs HEADERSIZE 0.
X If it says "executable" or "object" of some kind, you will
X have to set HEADERSIZE. If you get it right, but troff
X is still going wierd, set HEADERSIZE 0, and set COMPILE on
X in the Makefile (for some reason your troff is expecting
X a *real* a.out.h header, but I've never seen a troff that
X really needs this, but this is a way of getting the size
X right without having to guess/write a program to find the
X a.out.h size.
X
XNOTE for PSROFF 1.0 users:
X
X psroff 1.0 does not have a psroff.lib file, so changes (eg:
X width option specifications) have to be made directly to
X the psroff.sh shell script. Further, in the library, many of
X the files are reversed - eg: lj.lib in release 2.0 is lib.lj in 1.0.
X
X
XMost initial problems are due to width table installation/specification -
Xthis varies from system to system and is *very* confusing. I'm sorry about
Xthat, but there's no other way. As a simple guide: if the /usr/lib/font/ftR
Xfile in your original troff installation is not 224 bytes long, you *will*
Xhave to set HEADERSIZE or (remotely) COMPILE.
X
XAfter successful installation/testing, most problems are due to troff
Xerrors that you don't get to see.
X
XBuild/Execute gross failures:
X
XShell scripts die horrible deaths:
X
X Particularly with error messages from "test". Does your "test"
X support -x? If not, make sure that you've got SHELL and STARTSHELL
X set properly in the Makefile (The shell scripts assume V7 and/or USG
X versions of the Bourne Shell. Older BSD and some BSD derivitives
X (aka Ultrix) need a USG compatible shell - look for "sh5" somewhere
X on your system). ksh, bash and ash *should* work (untested).
X Maybe one of these days I'll make the shell scripts work with
X older shells/versions of test.
X
XThe makefile doesn't work:
X
X This *assumes* System V compatible MAKE. If the makefile blows
X (syntax errors in particular), search your system for a System V
X compatible version of make. Ultrix: /usr/bin/s5make. Gnumake should
X work fine. Most Suns need a change here too.
X
XOperational problems:
X
XNEW INSTALL: No output, or output truncated (possibly after some really
Xwild garble in the output):
X
X Troff is probably exploding. Run psroff debug - check in particular:
X for troff error messages about bad -T or -F options ("trofftype" see
X width tables and width option above) or not being able to find the
X width tables (did they really install?). If troff is core-dumping,
X it's probably a HEADERSIZE (above) problem, but it's possibly a
X problem with the width of a specific character (Xenix doesn't
X like zero (or sometimes really narrow) characters - try
X tests/dumpft < <width table file> > /tmp/FOO and look for errors
X and really narrow (0 or 1 unit) characters. Particularly \(ul/_/\(ru).
X
X Other possibilities: bad output settings (ptr and lparg), bad
X troff input.
X
XWORKING INSTALL (eg: it's worked fine before): same symptoms as previous.
X
X Troff is probably exploding, but probably not due to width tables.
X Run psroff debug. Check for and correct troff error messages (eg:
X line too long) in your document. This could even be troff not being
X able to find a file you specified to psroff.
X
XCharacter widths wildly and inconsistently off:
X
X Probably HEADERSIZE.
X
XCharacter widths annoyingly, inconsistently, but not wildly off:
X
X Remotely HEADERSIZE, more probably -T/-F trofftype omitted/wrong,
X or the width tables are simply wrong for the specific font or printer
X (you may want to experiment with the "width" option in lib/psroff.lib.S).
X Use "ps" for postscript printers and some others.
X
XCharacter widths uniformly off with ditroff:
X
X - "-R" wrong or omitted in psroff.lib.S t2arg. Check DESC file
X for proper value (default 300) and that the gfnttab log doesn't
X complain about a missing resolution during width table build.
X - DESC file has wrong resolution (default is 300). Try adjusting.
X The ps widths use 720 (in DESC file)
X - width option.
X
XCharacter widths uniformly off with non-ditroff:
X
X - wrong width tables - try using the right ones: check width option.
X - scaling bug in pk2ditwid/dit2catwid/gfnttab: contact me.
X
XA very few characters have bad widths:
X
X - manually adjust the widths/width<widthname>/* files and
X cd utils; make widths; su root; make installwidths.
X
Xoutput wacko with psfig, pic or grap (eg: overstrikes etc.):
X
X psroff doesn't work with pic, grap or psfig. Buy ditroff and throw
X psroff in the garbage. (There may eventually be support for pic,
X grap and psfig, but don't rely on it). I have some stuff to allow
X limited psfig functionality with psroff, but I decided not to release
X it at this point. Ask me if you *really* need it - '.sR "I..."'
X and '.sR "P...."' can more than replace psfig with the addition
X of some difficulty of use.
X
Xoutput wacko during a table (output possibly truncated):
X
X run psroff debug - probably line too long (table too wide).
X
Xoutput looks pretty good, but wierd things happen in spots:
X
X are you using ditroff features that CAT troff doesn't support?
X Eg: \X, \D, .sy, some "odd" permutations of \f, .ft, .fp? Font
X numbers > 4? CAT Troff (and hence psroff) doesn't support them.
X (CAT Troff does not work with pic or grap either)
X
XLooks good, but every second line has overstrikes at the end, the alternate
Xlines are indented:
X
X ".po" + ".ll" setting too high (CAT troff imposes 7.54" limit on total).
X Reduce ".po" and compensate with "-O" option to psroff. I've had
X some rumors of *some* kinds of Xenix troff having a shorter maximum
X width.
X
XRight shifted when compared to ditroff/nroff/cat troff with packages
Xother than psroff:
X
X See -O option and macro adapter description for psroff.
X
XUtter garbage output:
X
X Are you specifying the right driver?
X
XMM ".MT" macro doesn't appear to work properly:
X
X If you use a special directive (".sR" or ".fp" as modified by
X the adapter macros) before ".MT", .MT will get buggered up.
X Sorry, no workaround (though most requests other than ".fp"
X can be issued by psroff -P options). This isn't really a bug -
X a limitation of CAT troff's ability to pass additional directives
X to the backend without interfering with the typesetter state.
X Maybe one of these days I'll get around to figuring out a better
X mechanism.
X
XPage headers wrong or present on the first page when they shouldn't be:
X
X See previous (replace ".MT" with page header macros in discussion).
X
Xline lengths a bit different from nroff/ditroff/other non-psroff CAT troff:
X
X See macro adapter discussion in psroff/troff2ps man pages.
X
X".sR" doesn't appear to work at all:
X
X Run psroff debug - do you see lines of the form "M<sR macro argument>"?
X If not, you probably didn't get the macro adapters properly initialized.
X psroff as distributed has adapters for MS, MM and MAN. If you're
X using different ones, or invoking the macros by /usr/lib/tmac paths,
X or using no macros at all, the adapters and .sR definition won't be
X picked up. You will have to hand-craft your own macro adapter using
X common.pre and common.post, using one of the example tmac's.
X (all in adapters/* in distribution or LIBDIR/adapters after install)
X
X".sR" causes breaks/font loads don't happen at the right time:
X
X It has to unfortunately. If you want to load fonts (.fp) during a line,
X *don't*. Issue the ".fp"'s where it's safe to have a break. Ditto
X other ".sR" directives. There's no restrictions on changing to
X an *already loaded* font (eg: .ft directives). The psroff -P option
X may help (not .fp's, sorry...)
X
XSome things appear really wierd (eg: strings of character repeats
Xin page number on MM headers):
X
X Your CAT troff may not support \g (pure V7 troffs f'r instance).
X Experiment. You may have to bugger around with the macros to
X remove dependence on \g. (which is supposed to return a code
X denoting the output format of a number register, and is usually
X used to determine whether a number register has ever been set)
X
XME macros don't seem to work:
X
X A friend noted:
X
X In order to make them useable, I had to modify them somewhat. The
X problem was with the following syntax:
X
X .if t \
X \{
X . zz
X .\}
X
X Our (Xenix) troff required the following instead:
X
X .if t \{\
X . zz
X .\}
X
X This was required for all occurances of "\{". It seems "\{" MUST
X terminate a line, and MUST be followed by a "\<NEWLINE>". Even a ".\{"
X didn't help any.
X
XEverything okay, but some characters missing (or wrong) on output:
X(ditroff drivers may complain about characters not found)
X
X Chances are that your printer or set of fonts doesn't support
X that character. Postscript driving should be perfect. Some
X ditroff drivers don't have character sets that are a superset
X of CAT troff. There are a few minor problems with LJ character
X sets. psdit, xproof, xtroff are missing a few CAT characters.
X You may be able to resolve these by adding translation overrides
X to the appropriate *.fonts file (see jt.fonts for examples).
X Some ditroff's have different meanings for the same character
X spec. ("@" in some ditroff drivers is a different character)
X
XMy ditroff driver dies with errors about lines starting with "#":
X
X define NOCHATTER.
X
XMy postscript printer server gets upset:
X
X define NOCHATTER
X
XI get postscript printer errors on last page, or last page missing:
X
X Have you got a DEC LN03 or some other printer that doesn't
X like trailing control-D's? Define "NOCONTROLD" in defs.h
X
XDitroff driver doesn't work/gives errors:
X
X check, recheck, and check again for ditroff backend config
X (lparg/ptr in psroff.lib.S). Try "psroff -t" and then
X hand feeding the stdout to your backend manually. Experiment
X with "-d" setting in t2arg in psroff.lib.S. If related
X to specific characters, maybe adding translation overrides
X in the appropriate *.fonts file will help
X
XLaserjet printers get confused and loses settings (eg: copy count etc)
X
X Be aware of the fact that lj.lib has a RESET command. If you
X have some sort of spooler that's emitting commands to the printer
X outside of the control of psroff (eg: copy count set before
X psroff output), you may have to change it.
X
XLaserjet: wrong font selection (particularly when the result is
X10 point Courier), troff2ps compaining that it can't find a font
Xfile:
X
X - lj.fonts incorrect.
X - Don't have any good font files - buy some good ROMAN8's for
X Roman, Italic and Bold, or use TeX fonts and "make buildljfonts".
X
XLaserjet: lousey/wrong/missing characters (non-S font):
X
X - You got crummy fonts. Go buy or steal some good ROMAN8's in Roman,
X Italic and Bold at CAT troff's supported point sizes.
X TeX's PK fonts will work, but non-alphanumeric characters will
X often be wrong (particularly box drawing and backslash)
X - Get a Pacific Page or HP Postscript cartridge.
X
XMy laserjet stalls, gives "too complex" messages, doesn't switch fonts
Xsometimes:
X
X - Some HPLJ clones don't support incremental downloading. undefine
X INCR and try again. Plain laserjets (the old ones) don't support
X font downloading at all. Sigh...
X - Ran out of memory - (INCR on): simplify document to use less fonts
X or reduce MDLF.
X - Ran out of memory - (INCR and PARTIAL off): turn on PARTIAL
X - Too many fonts previously loaded - adjust PRELOAD.
X - double check MDLF.
X
XManual pages look great except the page footers are at the top of the
Xnext page. MM and MS work fine.
X
X - You're IBM AIX right? Sigh.... The man macros in AIX explicitly
X set page length to something other than 11 inches. Supply
X "-rM1" to psroff, and the macros will select 11 inches. Or,
X you could insert a ".nr M 1" the beginning of adapters/tmac.an.
X
XSQTroff ditroff backend sometimes barfs on psroff ditroff output:
X
X It do do that don't it? SQTroff ditroff format is apparently
X slightly different. Then again, if you got SQTroff, why you have
X psroff?
X
Xxproof sometimes dies with "too many font" messages:
X
X - AT&T's fault. (Each symbol character is a separate font, xproof
X is configured for a maximum of 50 or so fonts... duh...)
X
XThe Bell Symbol (\(bs) isn't:
X
X It ain't supposed to be.
X
XPsroff is wonderful:
X
X Thank you!

X.TH DUMPFT 1 local
X.SH NAME
Xdumpft \- Look at troff font width files
X.SH SYNOPSIS
X.B dumpft
X.B "[-s]"
X.B "[-t]"
X.B "[-w]"
X.B "[-f]"
X.B "[-d]"
X.BI "[-h" skip "]"
X.BI "[" options "]"
X< width
X.SH DESCRIPTION
XThe
X.B dumpft
Xprogram allows you to look at CAT troff width files.
XIt produces on standard output a ditroff-like width table.
XThe unitwidth is 6 and the resolution is 432, so the numbers
Xyou see are precisely the same as are in the CAT file.
X.P
XThe produced width table can be modified and used with
X.B dit2catwid
Xto generate new width tables, but you should specify
Xthe
X.B -d
Xoption.
XThe
X.B -d
Xoption tells dumpft to generate the widths with a unitwidth of 10
Xand resolution 300 which matches the
X.B dit2catwid
Xdefaults.
X.RB ( dit2catwid
Xdoesn't support changing unitwidth (yet)).
X.P
XThe
X.B -s
Xoption tells
X.B dumpft
Xthat the width table it's reading is for the
Xsymbol font
X(usually
X.BR ftS ")."
X.P
XThe
X.B -t
Xoption tells
X.B dumpft
Xto dump the names of each of the characters in the font table
Xa form suitable for wrapping .TS/.TE around to generate a full
Xset of CAT troff character tables.
X.P
XThe
X.B -w
Xoption tells
X.B dumpft
Xto dump all of the characters in the font table
Xas a set of strings for inclusion in troff
Xdocuments.
X.P
XSimilarly, the
X.B -f
Xoption tells psroff to generate a formatted example of all CAT troff
Xcharacters in the R, I, B and S fonts.
X.P
XFor various reasons, you might want to look at CAT troff width tables
Xfrom systems that have different width file formats.
XCAT troff width files vary from system to system by how much extraneous
Xjunk is prepended to the actual 224 byte table.
XOften, width tables are generated by compiling a C char array.
XSome vendors remove the a.out header from the beginning of the resultant
Xobject file, and others leave it there.
XIn order to interpret the width tables the program must skip over
Xthe junk (if any).
X.P
XThe
X.BI "-h" skip
Xtells
X.B dumpft
Xto skip \fIskip\fP bytes before reading the table.
XThe default
Xskip is set to what you built
X.B psroff
Xwith (HEADERSIZE define), you only need to specify
X.B -h
Xif you're reading width files from another system.
X.P
XFYI: Xenix usually has HEADERSIZE 0.
XSun and Ultrix (and probably other BSD derived systems)
Xshould have HEADERSIZE 32.
X.P
XIf you have difficulties setting HEADERSIZE correctly, you might
Xwant to use this option with varying settings
Xon /usr/lib/font/ftR (as supplied by your vendor) until
X.B dumpft
Xstops screeching about missing widths.
X.P
X.B Dumpft
Xprovides error messages on stderr if width entries are
Xmissing or extra ones are found.
XIf you get lots of error messages, you're probably looking at a S
Xfont file without
Xthe
X.B -s
Xoption or vice-versa, or HEADERSIZE is wrong.
X.P
XFor the curious, the full set of width table entries are in the
Xsource for
X.B cattab.c
Xin the psroff source directory.
