problem with autoconf
by The Thanh Han 25 May '05

25 May '05

Hi, having removed pdfxtex from the sources I tried to rerun autoconf to re-create the configure scripts. I am using debian sarge and got the following error: ,-------- | autoconf: invalid option -m `-------- I looked into the manpage and tried to replace '-m' by '-B', then '-I' Then I got some error with the pb_AC_ASM_UNDERSCORE macro. Searched using google showed that Sebastian Rahtz had the same problem and was not very successful to get it work. Then I uncommented out in texk/etc/autoconf/acsite.m4 the line ,-------- | undefine([pb_AC_ASM_UNDERSCORE]) `-------- and was able to go a little bit further: ,-------- | $sh reautoconf | . | configure.in:222: warning: AC_CONFIG_SUBDIRS: you should use literals | autoconf/status.m4:1078: AC_CONFIG_SUBDIRS is expanded from... | configure.in:222: the top level | /home/thanh/pdftex/src/thanh/libs | libs | configure.in:53: warning: AC_CONFIG_SUBDIRS: you should use literals | autoconf/status.m4:1078: AC_CONFIG_SUBDIRS is expanded from... | configure.in:53: the top level | /home/thanh/pdftex/src/thanh/texk | texk | configure.in:61: warning: AC_CONFIG_SUBDIRS: you should use literals | autoconf/status.m4:1078: AC_CONFIG_SUBDIRS is expanded from... | configure.in:61: the top level | /home/thanh/pdftex/src/thanh/libs/xpdf | libs/xpdf | /home/thanh/pdftex/src/thanh/texk/dvipsk | texk/dvipsk | /home/thanh/pdftex/src/thanh/texk/kpathsea | texk/kpathsea | /home/thanh/pdftex/src/thanh/texk/web2c | texk/web2c | configure.in:47: warning: AC_PROG_LEX invoked multiple times | autoconf/programs.m4:438: AC_DECL_YYTEXT is expanded from... | configure.in:47: the top level `-------- But when I tried to run configure from the top level I got: /home/thanh/pdftex/src/thanh/configure: line 6971: syntax error: unexpected end of file I have to say what Sebastian wrote in his mail: ,-------- | | I think I just hate computers! | `-------- Please, any ideas what I should try next?

Ugly rules in PDF
by Taco Hoekwater 23 May '05

23 May '05

Hi, After some discussion with Karl Berry on math-font-discuss: At Bachotek2005 there was a talk about the Latin Modern fonts, and there was a small math example included, of course. The presentation was shown using Adobe's PDF reader, and as you probably know, it displays the rules TeX draws for fractions and the radical bar horribly. The same is, in fact, true for xpdf and ghostview. The general problem is that rendering graphics and rendering text are not the same thing in PDF (nor PostScript), and that makes it hard for a viewer to align the two objects correctly. Our 'problem' is that people in general believe this is a bug in pdftex :-( An example file is at http://tex.aanhet.net/temp/mathtest.pdf Especially look at the top left of the sqrt signs. The source code is trivial: $$\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{x+1}}+1}+1}+1}+1}$$ I volunteered to write a patch for pdftex to try to remove the problem by making pdftex use a repeated character instead of a rule, but I am still a bit unsure about the best solution. Also, I vaguely remember that possibly somebody had done something with \radical a long time ago already, so I thought I'd ask feedback before doing any actual coding. Here is what I propose: The creation of a new primitive called \mathrulechar, with the following semantics. Adding \mathrulechar="0130 somewhere in the TeX source would make subsequent \radical commands use a suitable number of repetitions of the character "30 in math family 1 instead of the horizontal rule pdfTeX draws currently. No additional macros are involved in the process. (A suitable character has to be available, of course. It should be a dash, positioned flat on top of the baseline, no sidebearings) Greetings, Taco
