This file describes various problems that have been encountered in
|
||
compiling, installing and running groff. Suggestions for additions or
|
||
other improvements to this file are welcome.

Generic Problems
|
||
================
|
||
|
||
|
||
|
||
* My document says that the current year is 19100, not 2000.
|
||
|
||
In groff, as in traditional troff, the yr number register yields the
|
||
year minus 1900. Unfortunately, there is a longstanding bug in the
|
||
Troff User's Manual <http://cm.bell-labs.com/cm/cs/cstr/54.ps.gz>,
|
||
which incorrectly claims that yr is the last two digits of the year.
|
||
This claim was never true of either Unix troff or of groff.
|
||
|
||
If your text looks like this:
|
||
|
||
.\" Wrong:
|
||
This document was formatted in 19\n(yr.
|
||
|
||
you can correct it as follows:
|
||
|
||
This document was formatted in \n[year].
|
||
|
||
or, if you want to be portable to older troff versions, as follows:
|
||
|
||
.nr y4 1900+\n(yr
|
||
This document was formatted in \n(y4.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* groff can't handle my troff document. It works fine with AT&T
|
||
troff.
|
||
|
||
Read the section on incompatibilities in groff_diff(7). Try using
|
||
the -C option. Alternatively there's the sed script
|
||
`tmac/fixmacros.sed' which will attempt to edit a file of macros so
|
||
that it can be used with groff without the -C flag.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* gtroff doesn't understand lines like `.ce99' with no space between
|
||
the name of the request or macro and the arguments.
|
||
|
||
gtroff requires a space between macro or request and its arguments
|
||
because it allows the use of long names for macros and requests. You
|
||
can use the -C option or the `cp' request to put gtroff into a
|
||
compatibility mode in which it is not possible to use long names for
|
||
macros but in which no space is required between macros and their
|
||
arguments. The use of compatibility mode is strongly discouraged.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* groff -Tdvi produces dvi files that use fonts at weird
|
||
magnifications.
|
||
|
||
Yes, it does. You may need to compile fonts with Metafont at these
|
||
magnifications. The CompileFonts script in the devdvi/generate
|
||
directory may help you to do this. (It will take a *long* time on
|
||
slow computers.)
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* Groff doesn't use the font names I'm used to.
|
||
|
||
Use the `ftr' request. See groff_diff(7).
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* pic output is not centered horizontally; pictures sometimes run off
|
||
the bottom of the page.
|
||
|
||
The macro package you are using is not supplying appropriate
|
||
definitions of PS and PE. Give groff a -mpic option.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* gpic doesn't accept the syntax `chop N M' for chopping both ends of
|
||
a line.
|
||
|
||
The correct syntax is `chop N chop M'.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* With gpic -t, when I print `line ->; box' using a dvi to ps program,
|
||
the arrow head sticks through into the inside of the box.
|
||
|
||
The dvi to ps program should be modified to set the line cap and line
|
||
join parameters to 1 while printing tpic specials.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* gtroff gives warnings about lines like
|
||
.ev \" a comment
|
||
(with a tab after the .ev).
|
||
|
||
A tab character cannot be used as a substitute for a space character
|
||
(except in one case: between a control character at the beginning of a
|
||
line and the name of a macro or request). For example, in Unix troff
|
||
|
||
.ps \" restore the previous point size
|
||
|
||
(with a tab after the .ps) will NOT restore the previous point-size;
|
||
instead it will be silently ignored. Since this is very likely to be
|
||
an error, gtroff can give a warning about it. If you want to align
|
||
comments, you can do it like this:
|
||
|
||
.ev\" \" a comment
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I don't like the page headers and footers produced by groff -man.
|
||
|
||
There seem to be many different styles of page header and footer
|
||
produced by different versions of the -man macros. You will need to
|
||
put modified macros from tmac/an-old.tmac into man.local. More
|
||
information is available in groff_man(7).
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* Where can I get grap?
|
||
|
||
Ted Faber <faber@lunabase.org> has written a freely available grap:
|
||
|
||
http://www.lunabase.org/~faber/Vault/software/grap/
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* The \n(st and \n(sb registers don't seem to work. I thought \w set
|
||
them to the height and depth of its argument, but the registers
|
||
always seem to be 0.
|
||
|
||
\n(st and \n(sb aren't supposed to give the height and depth of the
|
||
string rather they give the minimum and maximum vertical displacement
|
||
of the baseline. For example for \v'2u'\v'-3u', \n(st will be 1 and
|
||
\n(sb will be -2. The height and depth of the string is available in
|
||
the \n[rst] and \n[rsb] registers: these are groff extensions.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* While formatting a manual page, groff complains about not being able
|
||
to break lines. The problem seems to be caused by a line like:
|
||
.TP \w'label'+2
|
||
|
||
The -man documentation says that the default scale indicator for TP
|
||
macro is `n'. The groff -man macros implement this correctly, so that
|
||
the argument will be evaluated as if it were
|
||
|
||
\w'label'n+2n
|
||
|
||
The Unix -man macros don't implement this correctly (probably because
|
||
it's hard to do in Unix troff); they just append `n' to the entire
|
||
argument, so that it will be evaluated as if it were
|
||
|
||
\w'label'u+2n
|
||
|
||
The solution is to fix the manual page:
|
||
|
||
.TP \w'label'u+2
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I'm having problems formatting man pages produced by the perl
|
||
wrapman script.
|
||
|
||
Some versions of wrapman have a superfluous blank line before the .TH
|
||
line. This must be deleted. Then either use groff -C, or apply the
|
||
following patch:

386BSD includes an old version of g++, 1.39, which has a bug that

Printing and Display Problems
|
||
=============================
|
||
|
||
|
||
|
||
* I'm having problems including PostScript illustrations (EPS) using
|
||
the PSPIC macro and/or \X'ps: import ...'.
|
||
|
||
A PostScript document must meet three requirements in order to be
|
||
included with the PSPIC macro: it must comply with the Adobe Document
|
||
Structuring Conventions; it must contain a BoundingBox line; it must
|
||
be ``well-behaved''. The BoundingBox line should be of the form:
|
||
|
||
%%BoundingBox: llx lly urx ury
|
||
|
||
where llx, lly, urx, ury are the coordinates of the lower left x,
|
||
lower left y, upper right x, upper right y of the bounding box of
|
||
marks on the page expressed as integers in the default PostScript
|
||
coordinate system (72 units per inch, origin at bottom left corner).
|
||
|
||
The most convenient program to get the bounding box of a document is
|
||
the `ps2epsi' script coming with GhostScript.
|
||
|
||
If you can't use this program, another useful tactic is to print out
|
||
the illustration by itself (you may need to add a `showpage' at the
|
||
end), and physically measure the bounding box. For more detail on
|
||
these requirements, read the specification of Encapsulated PostScript
|
||
format. (This is available from the Adobe file server; send a message
|
||
with a body of `help' to ps-file-server@adobe.com.)
|
||
|
||
If an EPS file to be included via \X'ps: import' does not start with
|
||
%!PS-Adobe-...', gtroff will still include the file, but grops will
|
||
not add any fonts to the generated output file that are listed in the
|
||
EPS file, even though the files are listed in the `download' file and
|
||
are available in the devps directory.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I've configured groff for A4 paper, but gtroff still seems to think
|
||
that the length of a page (as returned by `\n(.p') is 11 inches.
|
||
|
||
This is intentional. The PAGE option during configuration is used
|
||
only by grops. For compatibility with ditroff, the default page
|
||
length in gtroff is always 11 inches. The page length can be changed
|
||
with the `pl' request.
|
||
|
||
A convenient way to set paper dimensions is to use the -dpaper option
|
||
of groff, together with proper -P options for the postprocessor
|
||
(overriding the default). For example, use the following for PS
|
||
output on A4 paper in landscape orientation:
|
||
|
||
groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
|
||
|
||
See groff_tmac(5) for more information.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I print the output of groff -Tps, the output is always shifted
|
||
up by about 0.7 inches; I'm using 8.5x11 inch paper.
|
||
|
||
Make sure that the paper size is `letter'. See groff_tmac(5).
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I try to run gxditview, I get the error:
|
||
Error: Widget viewport has zero width and/or height
|
||
|
||
This error means you haven't correctly installed the application
|
||
defaults file, GXditview.ad; ``make install'' does this for you
|
||
automatically, so either you didn't do ``make install'', or you don't
|
||
have imake configured correctly.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I preview documents using -TX75 or -TX100, the layout is not
|
||
the same as when I print the document with -Tps: the line and page
|
||
breaks come in different places.
|
||
|
||
Use groff -X -Tps.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I try to print the output of groff -Tps, I get no output at all
|
||
from the printer, and the log file shows the error
|
||
%%[ error: undefined; offendingcommand: BP ]%%
|
||
I'm using TranScript spooling software.
|
||
|
||
This is a bug in the page reversal filter in early versions of
|
||
TranScript. Change the `broken' parameter in
|
||
/usr/local/lib/groff/font/devps/DESC to 7.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I preview groff -Tps output using the Sun OpenWindows 2.0
|
||
pageview program, all the pages are displayed on top of each other.
|
||
|
||
This is a defect in pageview. Change the `broken' parameter in
|
||
/usr/local/lib/groff/font/devps/DESC to 2.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* With groff -TX75, -TX100 or -X, I can only view the first page.
|
||
|
||
The left mouse button brings up a menu that allows you to view other
|
||
pages.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When I print the output of groff -Tdvi, I just get a black dot in
|
||
upper left corner.
|
||
|
||
Some dvi drivers (notably early versions of xtex) do not correctly
|
||
handle dvi files that use a resolution different from that used by dvi
|
||
files produced by TeX. Try getting a more up to date driver.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* How can I use groff with an old LaserJet printer that doesn't work
|
||
with groff -Tlj4?
|
||
|
||
You have at least 3 options:
|
||
|
||
- use groff -Tps with GNU Ghostscript;
|
||
|
||
- use groff -Tdvi with a TeX .dvi to Laserjet driver;
|
||
|
||
- use groff with the LaserJet driver in Chris Lewis' psroff package
|
||
(available for ftp from:
|
||
ftp.uunet.ca:/distrib/chris_lewis/psroff3.0pl17).
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* Groff seems to generate level 3 Postscript, but my printer is only a
|
||
level 1 or 2 PostScript printer.
|
||
|
||
In fact groff generates only level 2 PostScript (or rather level 1
|
||
with some extensions; see grops(1) for more information how to disable
|
||
them). The `%!PS-Adobe-3.0' comment at the beginning of PostScript
|
||
output generated by groff indicates that the file conforms to
|
||
version 3.0 of the Adobe Document Structuring Conventions. The output
|
||
generated by groff should be printable on any PostScript printer.
|
||
Problems with groff output's not printing are most often caused by the
|
||
spooling system.
|
||
|
||
|
||
|
||
Platform-Dependent Macro Problems
|
||
=================================
|
||
|
||
|
||
|
||
* I get lots of errors when I use groff with the AT&T -mm macros.
|
||
|
||
Use the groff -mm macros.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* groff produces wrapper macros for `ms' and friends which call the
|
||
system's original macros. Then, to get groff's ms macro package I
|
||
have to use `-mgs' instead `-ms'. Can I avoid this?
|
||
|
||
Yes. Configure and compile groff as usual, but install it with
|
||
|
||
make install tmac_wrap=""
|
||
|
||
Then no wrapper files are produced, and `-ms' will use groff's `ms'
|
||
macros.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I'm having problems formatting HP-UX 9.0 man pages with groff -man.
|
||
|
||
Copy HP's tmac.an into /usr/local/share/groff/site-tmac/an.tmac, and
|
||
either put `.cp 1' at the beginning or filter it (and any files it
|
||
.so's) through tmac/fixmacros.sed.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get errors using the Unix -ms macros with groff -e -C.
|
||
|
||
Apply this change:

|

|
||
* On an SGI system, how can I make the man command use groff?
|
||
|
||
From David Hinds <dhinds@allegro.stanford.edu> (some of these steps
|
||
are unnecessary if you install with the `g' Makefile variable defined
|
||
as empty):
|
||
|
||
Create a script called 'eqn':
|
||
|
||
> #!/bin/sh
|
||
> if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
|
||
> geqn $*
|
||
|
||
and a script called 'neqn':
|
||
|
||
> #!/bin/sh
|
||
> if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
|
||
> geqn -Tascii $*
|
||
|
||
and do:
|
||
|
||
> ln -s gnroff nroff
|
||
|
||
and edit the end of the gnroff script to be:
|
||
|
||
> rest=`echo ${1+"$@"} | sed -e 's+/usr/lib/tmac+/usr/local/lib/groff/tmac+'`
|
||
> exec groff -Wall -mtty-char $T $opts $rest
|
||
|
||
To get PostScript output from 'man -t', you also need to create a
|
||
'psroff' script similar to 'nroff'. Here are the context diffs:

Compilation Problems
|
||
====================
|
||
|
||
|
||
|
||
* Compilation dies with
|
||
|
||
y.tab.c: In function `int yyparse()':
|
||
y.tab.c: `size_t' undeclared in namespace `std'
|
||
|
||
* bison reports conflicts (either on stderr or in the `pic.output'
|
||
file) while processing `pic.y', and the produced pic binary doesn't
|
||
work at all.
|
||
|
||
You need bison version 1.875b or greater. Alternatively, use yacc or
|
||
byacc.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* There are many empty `Makefile.dep' files. Is this a bug?
|
||
|
||
No. Real dependency files are created with a `make depend' call.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* On HP-UX, the compiler complains about missing symbol `alloca'.
|
||
|
||
Say
|
||
|
||
export LDFLAGS=-lPW
|
||
|
||
before starting the configure script.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* The configure script fails on OS/390 (z/OS) Unix.
|
||
|
||
[This has been fixed in z/OS V1R3 (aka OS/390 R13).]
|
||
|
||
There is a bug in the Language Environment (LE) whereby the test
|
||
program for static destructors fails. You will see the message
|
||
`configure: error: a working C++ compiler is required'
|
||
|
||
Applying PTF UQ42006 is supposed to fix this, but the test program is
|
||
still returning the wrong value (1). To work around this problem, you
|
||
can comment out the following in the configure script (near line 2029).
|
||
This will effectively bypass the test (static constructors and
|
||
destructors do actually work properly):
|
||
|
||
#if { (eval echo "$as_me:2029: \"$ac_link\"") >&5
|
||
# (eval $ac_link) 2>&5
|
||
# ac_status=$?
|
||
# echo "$as_me:2032: \$? = $ac_status" >&5
|
||
# (exit $ac_status); } && { ac_try='./conftest$ac_exeext'
|
||
# { (eval echo "$as_me:2034: \"$ac_try\"") >&5
|
||
# (eval $ac_try) 2>&5
|
||
# ac_status=$?
|
||
# echo "$as_me:2037: \$? = $ac_status" >&5
|
||
# (exit $ac_status); }; }; then
|
||
# echo "$as_me:2039: result: yes" >&5
|
||
#echo "${ECHO_T}yes" >&6
|
||
#else
|
||
# echo "$as_me: program exited with status $ac_status" >&5
|
||
#echo "$as_me: failed program was:" >&5
|
||
#cat conftest.$ac_ext >&5
|
||
#echo "$as_me:2045: result: no" >&5
|
||
#echo "${ECHO_T}no" >&6;{ { echo "$as_me:2046: error: a working C++ compiler is required" >&5
|
||
#echo "$as_me: error: a working C++ compiler is required" >&2;}
|
||
# { (exit 1); exit 1; }; }
|
||
#fi
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get errors when I try to compile groff with DEC C++.
|
||
|
||
Fix the declaration of write() in <unistd.h> so that the second
|
||
argument is a const char *. Fix the declaration of open() in
|
||
<sys/file.h> so that the first argument is a const char *.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* On a host using Unix make (e.g. Solaris), if you are compiling for
|
||
multiple architectures by building in a subdirectory, the make stops
|
||
with a message like this:
|
||
|
||
make: Fatal error: Don't know how to make target `assert.o'
|
||
|
||
or like this:
|
||
|
||
make: Fatal error: Can't find /u/src/groff/src/include/Makefile.sub': No such file or directory
|
||
|
||
This occurs because GNU make and Unix make handle VPATH differently,
|
||
and the groff build relies on GNU make's VPATH handling.
|
||
|
||
Use GNU make to work around the problem. In Solaris 8, GNU make is
|
||
on the Software Companion CD and is installed as /opt/sfw/bin/gmake.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* On Ultrix, the make stops with the message
|
||
|
||
*** Error code 1
|
||
|
||
Stop.
|
||
|
||
for no apparent reason.
|
||
|
||
Use GNU make.

----------------------------------------------------------------------
|
||
|
||
* I get errors when I try to compile groff with Sun C++ version 3 or
|
||
earlier.
|
||
|
||
Groff requires header files that are moderately compatible with AT&T
|
||
C++ and ANSI C. With some versions of Sun C++, the supplied header
|
||
files need some of the following changes to meet this requirement:
|
||
<string.h> must declare the mem* functions, (just add `#include
|
||
<memory.h>' to <string.h>); the first argument to fopen and freopen
|
||
should be declared as `const char *'; the first argument to fread
|
||
should be declared as `void *'; the first argument to fwrite should be
|
||
declared as `const void *'; malloc should be declared to return
|
||
`void *'; in <alloca.h>, the declaration `extern "C" { void
|
||
*__builtin_alloca(int); }' should be added; in <sys/signal.h> the
|
||
return type and the second argument type of signal() should be changed
|
||
to be `void (*)(int)'.
|
||
|
||
You can either change them in place, or copy them to some other
|
||
directory and include that directory with a -I option.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get errors when I try to compile groff with Sun C++ version 5.0
|
||
or 5.1.
|
||
|
||
This is a known problem; see Sun bug #4301919. As of this writing, no
|
||
patch is available. Use GCC 2.95.2 or later instead.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get lots of `numeric overflow' error messages whenever I run
|
||
groff; I compiled groff with AT&T C++ 2.0 with an ANSI C compiler.
|
||
|
||
Make sure -DCFRONT_ANSI_BUG is included in DEFINES in the top-level
|
||
Makefile. If that doesn't solve the problem, define INT_MIN as
|
||
-INT_MAX in libgroff/lib.h.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* When compiling on MacOS X, groff compiles but does not run well.
|
||
|
||
Use ./configure CXX=g++2 then make as usual.
