1 This file describes various problems that have been encountered in 2 compiling, installing and running groff. Suggestions for additions or 3 other improvements to this file are welcome. 4 5 ---------------------------------------------------------------------- 6 7 8 9 Generic Problems 10 ================ 11 12 13 14 * Displaying a man page on a terminal with/without my favourite pager 15 only gives garbage. 16 17 groff by default now uses SGR escape sequences (`ANSI color') to 18 control the display attributes (bold, underlined, colour) on TTYs. 19 Some terminals (e.g. `kterm') don't understand SGR, and some pagers 20 (e.g. older versions of `less' or `less' without the -R option) don't 21 understand SGR either. There are three solutions to fix this, in order 22 of preference; please read the grotty man page for more details. 23 24 The fourth and probably best option is to update your terminal program 25 and pager to versions which can handle SGR. 26 27 1. Set the GROFF_NO_SGR environment variable. 28 29 2. Pass option -c to grotty. 30 31 3. Append the following fragment to the `troffrc' file: 32 33 34 --- start --- 35 .if n \{\ 36 . nr _C \n(.C 37 . cp 0 38 . 39 . \" The following code sets a top-of-page trap to disable grotty's TTY 40 . \" mode. Since neither \X nor .output can be used before the first 41 . \" page has started, we must use a trap. To make it work with troff's 42 . \" -o option, we wait until the first printed page. 43 . 44 . de sgr@dummy 45 . . 46 . 47 . rn wh wh@old 48 . 49 . \" The stand-alone version.

Why? 95 96 The used Unicode characters (U+2212 for the minus sign and U+2010 for 97 the hyphen) are the correct ones, but many programs can't search them 98 properly. The same is true for the right quote (U+201D). To map those 99 characters back to the ASCII characters, insert the following code 100 snippet into the `troffrc' configuration file: 101 102 .if '\*[.T]'utf8' \{\ 103 . char \- \N'45' 104 . char - \N'45' 105 . char ' \N'39' 106 .\} 107 108 109 ---------------------------------------------------------------------- 110 111 * My document says that the current year is 19100, not 2000. 112 113 In groff, as in traditional troff, the yr number register yields the 114 year minus 1900. Unfortunately, there is a longstanding bug in the 115 Troff User's Manual <http://cm.bell-labs.com/cm/cs/cstr/54.ps.gz>, 116 which incorrectly claims that yr is the last two digits of the year. 117 This claim was never true of either Unix troff or of groff. 118 119 If your text looks like this: 120 121 .\" Wrong: 122 This document was formatted in 19\n(yr. 123 124 you can correct it as follows: 125 126 This document was formatted in \n[year]. 127 128 or, if you want to be portable to older troff versions, as follows: 129 130 .nr y4 1900+\n(yr 131 This document was formatted in \n(y4. 132 133 ---------------------------------------------------------------------- 134 135 * groff can't handle my troff document. It works fine with AT&T 136 troff. 137 138 Read the section on incompatibilities in groff_diff(7). Try using 139 the -C option. Alternatively there's the sed script 140 `tmac/fixmacros.sed' which will attempt to edit a file of macros so 141 that it can be used with groff without the -C flag. 142 143 ---------------------------------------------------------------------- 144 145 * gtroff doesn't understand lines like `.ce99' with no space between 146 the name of the request or macro and the arguments. 147 148 gtroff requires a space between macro or request and its arguments 149 because it allows the use of long names for macros and requests. You 150 can use the -C option or the `cp' request to put gtroff into a 151 compatibility mode in which it is not possible to use long names for 152 macros but in which no space is required between macros and their 153 arguments. The use of compatibility mode is strongly discouraged. 154 155 ---------------------------------------------------------------------- 156 157 * groff -Tdvi produces dvi files that use fonts at weird 158 magnifications. 159 160 Yes, it does. You may need to compile fonts with Metafont at these 161 magnifications. The CompileFonts script in the devdvi/generate 162 directory may help you to do this. (It will take a *long* time on 163 slow computers.) 164 165 ---------------------------------------------------------------------- 166 167 * Groff doesn't use the font names I'm used to. 168 169 Use the `ftr' request. See groff_diff(7). 170 171 ---------------------------------------------------------------------- 172 173 * pic output is not centered horizontally; pictures sometimes run off 174 the bottom of the page. 175 176 The macro package you are using is not supplying appropriate 177 definitions of PS and PE. Give groff a -mpic option. 178 179 ---------------------------------------------------------------------- 180 181 * gpic doesn't accept the syntax `chop N M' for chopping both ends of 182 a line. 183 184 The correct syntax is `chop N chop M'. 185 186 ---------------------------------------------------------------------- 187 188 * With gpic -t, when I print `line ->; box' using a dvi to ps program, 189 the arrow head sticks through into the inside of the box. 190 191 The dvi to ps program should be modified to set the line cap and line 192 join parameters to 1 while printing tpic specials. 193 194 ---------------------------------------------------------------------- 195 196 * gtroff gives warnings about lines like 197 .ev \" a comment 198 (with a tab after the .ev). 199 200 A tab character cannot be used as a substitute for a space character 201 (except in one case: between a control character at the beginning of a 202 line and the name of a macro or request). For example, in Unix troff 203 204 .ps \" restore the previous point size 205 206 (with a tab after the .ps) will NOT restore the previous point-size; 207 instead it will be silently ignored. Since this is very likely to be 208 an error, gtroff can give a warning about it. If you want to align 209 comments, you can do it like this: 210 211 .ev\" \" a comment 212 213 ---------------------------------------------------------------------- 214 215 * I don't like the page headers and footers produced by groff -man. 216 217 There seem to be many different styles of page header and footer 218 produced by different versions of the -man macros. You will need to 219 put modified macros from tmac/an-old.tmac into man.local. More 220 information is available in groff_man(7). 221 222 ---------------------------------------------------------------------- 223 224 * Where can I get grap? 225 226 Ted Faber <faber (a] lunabase.org> has written a freely available grap: 227 228 http://www.lunabase.org/~faber/Vault/software/grap/ 229 230 ---------------------------------------------------------------------- 231 232 * The \n(st and \n(sb registers don't seem to work. I thought \w set 233 them to the height and depth of its argument, but the registers 234 always seem to be 0. 235 236 \n(st and \n(sb aren't supposed to give the height and depth of the 237 string rather they give the minimum and maximum vertical displacement 238 of the baseline. For example for \v'2u'\v'-3u', \n(st will be 1 and 239 \n(sb will be -2. The height and depth of the string is available in 240 the \n[rst] and \n[rsb] registers: these are groff extensions. 241 242 ---------------------------------------------------------------------- 243 244 * While formatting a manual page, groff complains about not being able 245 to break lines. The problem seems to be caused by a line like: 246 .TP \w'label'+2 247 248 The -man documentation says that the default scale indicator for TP 249 macro is `n'. The groff -man macros implement this correctly, so that 250 the argument will be evaluated as if it were 251 252 \w'label'n+2n 253 254 The Unix -man macros don't implement this correctly (probably because 255 it's hard to do in Unix troff); they just append `n' to the entire 256 argument, so that it will be evaluated as if it were 257 258 \w'label'u+2n 259 260 The solution is to fix the manual page: 261 262 .TP \w'label'u+2 263 264 ---------------------------------------------------------------------- 265 266 * I'm having problems formatting man pages produced by the perl 267 wrapman script. 268 269 Some versions of wrapman have a superfluous blank line before the .TH 270 line. This must be deleted. Then either use groff -C, or apply the 271 following patch: 272 273 *** wrapman.~2~ Sun Jan 19 12:10:24 1992 274 --- wrapman Tue Aug 10 02:06:41 1993 275 *************** 276 *** 35,41 **** 277 $line1 .= <IN> if $line1 =~ /eval/; 278 $line1 .= <IN> if $line1 =~ /argv/; 279 $line2 = <IN>; 280 ! next if $line2 eq "'di';\n"; 281 282 # Pull the old switcheroo. 283 284 --- 35,41 ---- 285 $line1 .= <IN> if $line1 =~ /eval/; 286 $line1 .= <IN> if $line1 =~ /argv/; 287 $line2 = <IN>; 288 ! next if $line2 eq "'di ';\n" || $line2 eq "'di';\n"; 289 290 # Pull the old switcheroo. 291 292 *************** 293 *** 49,56 **** 294 295 print OUT $line1; 296 print OUT <<EOF; 297 !

The BoundingBox line should be of the form: 396 397 %%BoundingBox: llx lly urx ury 398 399 where llx, lly, urx, ury are the coordinates of the lower left x, 400 lower left y, upper right x, upper right y of the bounding box of 401 marks on the page expressed as integers in the default PostScript 402 coordinate system (72 units per inch, origin at bottom left corner). 403 404 The most convenient program to get the bounding box of a document is 405 the `ps2epsi' script coming with GhostScript. 406 407 If you can't use this program, another useful tactic is to print out 408 the illustration by itself (you may need to add a `showpage' at the 409 end), and physically measure the bounding box. For more detail on 410 these requirements, read the specification of Encapsulated PostScript 411 format. (This is available from the Adobe file server; send a message 412 with a body of `help' to ps-file-server (a] adobe.com.) 413 414 If an EPS file to be included via \X'ps: import' does not start with 415 `%!PS-Adobe-...', gtroff will still include the file, but grops will 416 not add any fonts to the generated output file that are listed in the 417 EPS file, even though the files are listed in the `download' file and 418 are available in the devps directory. 419 420 ---------------------------------------------------------------------- 421 422 * I've configured groff for A4 paper, but gtroff still seems to think 423 that the length of a page (as returned by `\n(.p') is 11 inches. 424 425 This is intentional. The PAGE option during configuration is used 426 only by grops. For compatibility with ditroff, the default page 427 length in gtroff is always 11 inches. The page length can be changed 428 with the `pl' request. 429 430 A convenient way to set paper dimensions is to use the -dpaper option 431 of groff, together with proper -P options for the postprocessor 432 (overriding the default). For example, use the following for PS 433 output on A4 paper in landscape orientation: 434 435 groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps 436 437 See groff_tmac(5) for more information. 438 439 ---------------------------------------------------------------------- 440 441 * When I print the output of groff -Tps, the output is always shifted 442 up by about 0.7 inches; I'm using 8.5x11 inch paper. 443 444 Make sure that the paper size is `letter'. See groff_tmac(5). 445 446 ---------------------------------------------------------------------- 447 448 * When I try to run gxditview, I get the error: 449 Error: Widget viewport has zero width and/or height 450 451 This error means you haven't correctly installed the application 452 defaults file, GXditview.ad; `make install' does this for you 453 automatically, so either you didn't do `make install', or you haven't 454 passed a good `--appresdir=<DIR>' argument to groff's configure script. 455 456 See the X(7) man page for information how and where application resource 457 files have to be located. Look for the XAPPLRESDIR and XUSERFILESEARCHPATH 458 environment variables. 459 460 ---------------------------------------------------------------------- 461 462 * When I preview documents using -TX75 or -TX100, the layout is not 463 the same as when I print the document with -Tps: the line and page 464 breaks come in different places. 465 466 Use `groff -X -Tps'. 467 468 ---------------------------------------------------------------------- 469 470 * When I try to print the output of groff -Tps, I get no output at all 471 from the printer, and the log file shows the error 472 %%[ error: undefined; offendingcommand: BP ]%% 473 I'm using TranScript spooling software. 474 475 This is a bug in the page reversal filter in early versions of 476 TranScript. Change the `broken' parameter in 477 /usr/local/lib/groff/font/devps/DESC to 7. 478 479 ---------------------------------------------------------------------- 480 481 * When I preview groff -Tps output using the Sun OpenWindows 2.0 482 pageview program, all the pages are displayed on top of each other. 483 484 This is a defect in pageview. Change the `broken' parameter in 485 /usr/local/lib/groff/font/devps/DESC to 2. 486 487 ---------------------------------------------------------------------- 488 489 * With groff -TX75, -TX100 or -X, I can only view the first page. 490 491 The left mouse button brings up a menu that allows you to view other 492 pages. 493 494 ---------------------------------------------------------------------- 495 496 * When I print the output of groff -Tdvi, I just get a black dot in 497 upper left corner. 498 499 Some dvi drivers (notably early versions of xtex) do not correctly 500 handle dvi files that use a resolution different from that used by dvi 501 files produced by TeX. Try getting a more up to date driver. 502 503 ---------------------------------------------------------------------- 504 505 * How can I use groff with an old LaserJet printer that doesn't work 506 with groff -Tlj4? 507 508 You have at least 3 options: 509 510 - use groff -Tps with GNU Ghostscript; 511 512 - use groff -Tdvi with a TeX .dvi to Laserjet driver; 513 514 - use groff with the LaserJet driver in Chris Lewis' psroff package 515 (available for ftp from: 516 ftp.uunet.ca:/distrib/chris_lewis/psroff3.0pl17). 517 518 ---------------------------------------------------------------------- 519 520 * Groff seems to generate level 3 Postscript, but my printer is only a 521 level 1 or 2 PostScript printer. 522 523 In fact groff generates only level 2 PostScript (or rather level 1 524 with some extensions; see grops(1) for more information how to disable 525 them). The `%!PS-Adobe-3.0' comment at the beginning of PostScript 526 output generated by groff indicates that the file conforms to 527 version 3.0 of the Adobe Document Structuring Conventions. The output 528 generated by groff should be printable on any PostScript printer. 529 Problems with groff output's not printing are most often caused by the 530 spooling system. 531 532 533 534 Platform-Dependent Macro Problems 535 ================================= 536 537 538 539 * I get lots of errors when I use groff with the AT&T -mm macros. 540 541 Use the groff -mm macros. 542 543 ---------------------------------------------------------------------- 544 545 * groff produces wrapper macros for `ms' and friends which call the 546 system's original macros. Then, to get groff's ms macro package I 547 have to use `-mgs' instead `-ms'. Can I avoid this? 548 549 Yes.

You will see the message 748 `configure: error: a working C++ compiler is required' 749 750 Applying PTF UQ42006 is supposed to fix this, but the test program is 751 still returning the wrong value (1). To work around this problem, you 752 can comment out the following in the configure script (near line 2029). 753 This will effectively bypass the test (static constructors and 754 destructors do actually work properly): 755 756 #if { (eval echo "$as_me:2029: \"$ac_link\"") >&5 757 # (eval $ac_link) 2>&5 758 # ac_status=$? 759 # echo "$as_me:2032: \$? = $ac_status" >&5 760 # (exit $ac_status); } && { ac_try='./conftest$ac_exeext' 761 # { (eval echo "$as_me:2034: \"$ac_try\"") >&5 762 # (eval $ac_try) 2>&5 763 # ac_status=$? 764 # echo "$as_me:2037: \$? = $ac_status" >&5 765 # (exit $ac_status); }; }; then 766 # echo "$as_me:2039: result: yes" >&5 767 #echo "${ECHO_T}yes" >&6 768 #else 769 # echo "$as_me: program exited with status $ac_status" >&5 770 #echo "$as_me: failed program was:" >&5 771 #cat conftest.$ac_ext >&5 772 #echo "$as_me:2045: result: no" >&5 773 #echo "${ECHO_T}no" >&6;{ { echo "$as_me:2046: error: a working C++ compiler is required" >&5 774 #echo "$as_me: error: a working C++ compiler is required" >&2;} 775 # { (exit 1); exit 1; }; } 776 #fi 777 778 ---------------------------------------------------------------------- 779 780 * I get errors when I try to compile groff with DEC C++. 781 782 Fix the declaration of write() in <unistd.h> so that the second 783 argument is a const char *. Fix the declaration of open() in 784 <sys/file.h> so that the first argument is a const char *. 785 786 ---------------------------------------------------------------------- 787 788 * On a host using Unix make (e.g. Solaris), if you are compiling for 789 multiple architectures by building in a subdirectory, the make stops 790 with a message like this: 791 792 make: Fatal error: Don't know how to make target `assert.o' 793 794 or like this: 795 796 make: Fatal error: Can't find /u/src/groff/src/include/Makefile.sub': No such file or directory 797 798 This occurs because GNU make and Unix make handle VPATH differently, 799 and the groff build relies on GNU make's VPATH handling. 800 801 Use GNU make <http://www.gnu.org/software/make/> to work around this. 802 In Solaris 8 and 9, GNU make is on the Software Companion CD in 803 package SFWgmake and is installed as /opt/sfw/bin/gmake.

With some versions of Sun C++, the supplied header 864 files need some of the following changes to meet this requirement: 865 <string.h> must declare the mem* functions, (just add `#include 866 <memory.h>' to <string.h>); the first argument to fopen and freopen 867 should be declared as `const char *'; the first argument to fread 868 should be declared as `void *'; the first argument to fwrite should be 869 declared as `const void *'; malloc should be declared to return 870 `void *'; in <alloca.h>, the declaration `extern "C" { void 871 *__builtin_alloca(int); }' should be added; in <sys/signal.h> the 872 return type and the second argument type of signal() should be changed 873 to be `void (*)(int)'. 874 875 You can either change them in place, or copy them to some other 876 directory and include that directory with a -I option. 877 878 ---------------------------------------------------------------------- 879 880 * I get errors when I try to compile groff with Forte Development 6 881 or 6u1, or Sun C++ version 5.0 through 5.2. 882 883 This is a known problem; see Sun bug #4301919. See Sun patches 884 109482, 109490, 109508, and 109509 for fixes. 885 886 ---------------------------------------------------------------------- 887 888 * I get warnings from the Sun linker while using gcc 3.4.0: 889 890 ld: warning: relocation error: R_SPARC_UA32: 891 file groff/src/libs/libgroff/libgroff.a(getopt.o): symbol optarg: 892 external symbolic relocation against non-allocatable 893 section .debug_info; cannot be processed at runtime: 894 relocation ignored 895 896 This seems to be a known problem (Sun bugs #4910101 and #4910810, 897 filed in September 2003; gcc bug #15599, filed May 2004) without a 898 public fix as of this writing. A work-around is to use option 899 `-gstabs+' instead of `-g' (and a high probability that the output is 900 only debuggable with gdb but not with Sun's debuggers). 901 902 ---------------------------------------------------------------------- 903 904 * I get lots of `numeric overflow' error messages whenever I run 905 groff; I compiled groff with AT&T C++ 2.0 with an ANSI C compiler. 906 907 Make sure -DCFRONT_ANSI_BUG is included in DEFINES in the top-level 908 Makefile. If that doesn't solve the problem, define INT_MIN as 909 -INT_MAX in libgroff/lib.h. 910 911 ---------------------------------------------------------------------- 912 913 * When compiling on MacOS X, groff compiles but does not run well, 914 especially `eqn', causing many `can't break line' messages. 915 916 Use ./configure CXX=g++2 then make as usual. 917
