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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* The configure script fails on OS/390 Unix.
|
||
|
||
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 956).
|
||
This will effectively bypass the test (static constructors and
|
||
destructors do actually work properly):
|
||
|
||
#if { (eval echo configure:957: \"$ac_link\") 1>&5; (eval $ac_link) 2>&5; } && test -s conftest${ac_exeext} && (./conftest; exit) 2>/dev/null
|
||
#then
|
||
echo "$ac_t""yes" 1>&6
|
||
#else
|
||
# echo "configure: failed program was:" >&5
|
||
# cat conftest.$ac_ext >&5
|
||
# rm -fr conftest*
|
||
# echo "$ac_t""no" 1>&6;{ echo "configure: error: a working C++ compiler is required" 1>&2; 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'm having problems compiling groff on 386BSD 0.1.
|
||
|
||
If you're using ash as /bin/sh, you'll need the following patch.

You'll also need to change dirnamemax.c so that it doesn't use

|

|

----------------------------------------------------------------------
|
||
|
||
* While compiling on Xenix, ranlib libgroff.a fails.
|
||
|
||
The system ranlib can't handle externals longer than 40 characters.
|
||
Use the ranlib included in demon.co.uk:/pub/xenix/g++-1.40.3a.v1
|
||
instead.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* There are many empty `Makefile.dep' files. Is this a bug?
|
||
|
||
No. Real dependency files are created with a `make depend' call.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* Groff can't handle my troff document. It works fine with AT&T troff.
|
||
|
||
Read the section on incompatibilities in gtroff(1). Try using the -C
|
||
option. Alternatively there's the sed script in tmac/fixmacros.sed
|
||
which will attempt to edit a file of macros so that it can be used
|
||
with groff without the -C flag.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.)
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I'm having problems including PostScript illustrations using the
|
||
PSPIC macro.
|
||
|
||
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).
|
||
A 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.)
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* Groff doesn't use the font names I'm used to.
|
||
|
||
Use the `ftr' request. See gtroff(1).
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get errors using the Unix -ms macros with groff -e -C.
|
||
|
||
Apply this change:

The correct syntax is `chop N chop M'.

* With gpic -t, when I print `line ->; box' using a dvi to ps program,

The dvi to ps program should be modified to set the line cap and line

by about 0.7 inches; I'm using 8.5x11 inch paper.

%%[ 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.

|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* I get lots of errors when I use groff with the AT&T -mm macros.
|
||
|
||
The AT&T -mm macros need a few changes to work with groff; `make
|
||
install.dwbmm' will copy your -mm macros to groff's macro directory
|
||
and make the necessary changes. You may need to edit the commands for
|
||
the install.mm target in the Makefile. Alternatively use the groff
|
||
-mm macros.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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
|
||
modify macros/tmac.an to suit your personal taste. For example, if
|
||
you want the center of the page header to say
|
||
|
||
System Programmer's Manual
|
||
|
||
you will need to change the line
|
||
|
||
.el .ds an-extra3 \"System Programmer's Manual
|
||
|
||
to
|
||
|
||
.el .ds an-extra3 System Programmer's Manual
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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 Ultrix man pages with groff -man.
|
||
|
||
The Ultrix man pages use a number of non-standard extensions to the
|
||
Unix man macros. One solution is to use the Ultrix -man macros with
|
||
groff. Rename /usr/local/lib/groff/tmac/tmac.an to
|
||
/usr/local/lib/groff/tmac/tmac.an.gnu, copy /usr/lib/tmac/tmac.an to
|

/usr/local/lib/groff/tmac/tmac.an and apply the following patch (from

* 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 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.

* groff uses up an enormous amount of memory processing large files.
|
||
I'm using 386BSD 0.1.
|
||
|
||
386BSD includes an old version of g++, 1.39, which has a bug that
|
||
causes a major memory leak in gtroff. Apply the following fix to g++
|
||
and recompile groff:

* Where can I get grap?
|
||
|

Ted Faber <faber@lunabase.org> has written a freely available grap:

* 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 1 PostScript. 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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.
|
||
|
||
----------------------------------------------------------------------
|
||
|
||
* 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:
