<P><FONT size=2 face="Courier New"><FONT size=2 face="Courier New">After a few
weeks of time, gratefully I found what I will call a "workaround" solution for
this problem of the LaTeX code \frac{1}{2} being converted to the word "Image"
instead of the fraction 1/2 with a horizontal fraction line in a LaTeX2HTML
output file. That solution was the result of a good clue kindly
provided by Bob Tennent. On
http://www.tug.org/pipermail/tex-live/2011-November/030599.html on the Internet
he wrote, "...in some Linux distributions the latex2html package will *depend*
on a full installation of something hopelessly out-of-date like texlive-2007 or
tetex which complicates the installation" (of I think LaTeX2HTML). And at
http://www.tug.org/pipermail/tex-live/2011-November/030604.html, continuing in
the same "chain" of likely electronic-mail letters, Bob Tennent further wrote,
"Installation of latex2html-2008 from the tarball at CTAN" (the Comprehensive
TeX Archive Network on the Internet) "does avoid the dependency issues and it's
likely to need updating." These writings of Bob Tennent gratefully gave me the
clue that LaTeX2HTML 1.71, which worked probably well for me with portions of
TeX Live 2011, might be non-commensurate in some way with portions of TeX Live
2012. So in attempting the solution of Bob Tennent I obtained the file
latex2html-2012.tgz from a CTAN Web page. Within openSUSE-12.3's Yet another
Software Tool 2's (YaST2's) Software Management I deleted the installations of
the openSUSE-12.3 software packages entitled "latex2html," "latex2html-doc," and
"latex-pngicons." I unpacked the downloaded file latex2html-2012.tgz using the
command "tar xvzf latex2html-2012.tgz" in a new folder and followed the
instructions in a file entitled "INSTALL," which came within that .tgz file to
install what turned out to be LaTeX2HTML 2012 (1.2) in my installation of
portions of TeX Live 2012 in an openSUSE-12.3, Linux operating system. The
essential commands in doing so were "./configure --prefix=/usr", "make," and
"make install". The result was the installation of some executable LaTeX2HTML
files in the directory /usr/bin, some shared library files in the directory
/usr/shared/lib/latex2html, and some unshared library files in the directory
/usr/lib/latex2html, with each of those three directories beginning with the
input "prefix" of "/url". After deleting old copies of everything associated
with my test file Throwaway29.tex, except the file Throwaway29.tex itself,
gratefully the result of executing "latex Throwaway29.tex" twice and "latex2html
-debug -nonavigation -no_math -html_version 3.2,math -split 0 Throwaway29.tex"
once was that the equivalent of the expression y=(1/2) x^2 without the
parentheses and with a horizontal fraction line was properly displayed in the
output file ..../Throwaway29/Throwaway29.html when viewed in the Web browser
Konqueror (Some problems in displaying other mathematics after similarly
processing a different .tex file were rectified by making the minor changes
discussed in Appendix II.). Afterwards the new folder into which the file
latex2html-2012.tgz, which had been downloaded from a CTAN Web page, had been
unpacked could be deleted from my computer's hard-disk drive. </P>
<P><FONT face=Arial></FONT> </P>
<P>The above success shows that LaTeX2HTML 2012 (1.2) can be made to work with
portions of TeX Live 2012 in an openSUSE-12.3, Linux operating system (As of
August 14, 2013, TeX Live 2013 was not yet available for installation from the
standard openSUSE-12.3 repositories for stable openSUSE 12.3. But from Harvey's
posting at http://bbs.archlinux.org/viewtopic.php?pid=1299370 on the Internet,
there is a possible clue that TeX Live 2013 may have worked with LaTeX2HTML
2008-2, dated July 10, 2013, up to, but not including, the TeX Live 2013 update
named texlive-core2013.30962-1. Based on Harvey's joke near the end of his
posting there and because that Web page has "linux" in its Uniform Resource
Locator [URL], I suppose that Harvey may have been using some distribution of a
Linux operating system in the results he reported. He also wrote that he
reported his problem with LaTeX2HTML 2008-2 and TeX Live 2013, a problem
different from my problem with LaTeX-coded fractions like \frac{1}{2}, as a
"bug." I am not certain whether he reported that software "bug" to the
developers of TeX Live or to the developers of the distribution of the Linux
operating system that he was using at the time he found what he speculated might
be a "bug."). Without delving deeply into the computer codes involved, I have
two general hypotheses to explain this success: 1) Similar to what Bob Tennent
reported for probably an earlier version of LaTeX2HTML and some distribution or
distributions of a Linux operating system that is or are unknown to me, perhaps
in my case as well there was in some way some kind of a mismatch between
LaTeX2HTML 2008 (1.71) and portions of TeX Live 2012 in my installation of the
openSUSE-12.3, Linux operating system. 2) In openSUSE 12.3, compared to openSUSE
12.2, I think some changes were made in grouping some software packages
together. So perhaps there was a problem on the openSUSE-12.3 side of things
that prevented LaTeX2HTML 1.71 from working well with portions of TeX Live
2012.</P>
<P><FONT face=Arial></FONT> </P>
<P>I see short-, intermediate-, and long-term solutions to the general problem
of getting LaTeX2HTML to work well with portions of TeX Live in a Linux
operating system. The short-term solution is the one I explained in the
paragraph two paragraphs above this one that gratefully worked for me in an
openSUSE-12.3, Linux operating system and that one could hope might also work in
other distributions of the Linux operating system. The intermediate-term
solution is to have openSUSE-12.3 developers fix the problem for users of the
version of LaTeX2HTML that is supplied to openSUSE-12.3 users from
openSUSE-12.3's software repositories (In fact, I have already submitted the
problem I mention here in a "bug" report to developers of openSUSE 12.3. I
updated that "bug" report with the recent success and some of the other content
I report here.).---If the above hypothesis 1 is correct without any
complications from hypothesis 2, the intermediate-term solution might be as
simple as openSUSE-12.3 developers changing the version of LaTeX2HTML they
supply from their online repositories from the year-2008 to the year-2012
version of it that is available from the CTAN. But the long-term and more
general solution for all distributions of the Linux and Windows operating
systems which may make use of TeX Live could be to incorporate a recent version
of LaTeX2HTML in a recent version of TeX Live and, from testing LaTeX2HTML and
LaTeX in TeX Live with .tex files containing some mathematical expressions
before distributing Tex Live, to in that way ensure that LaTeX2HTML within TeX
Live will work well with TeX Live. Via electronic mail I recently recommended
such incorporation to people who use and/or are responsible for TeX Live. </P>

<P>Appendix II: Changes That Were Necessary to Make in LaTeX2HTML 2012 Files to
Avoid Some Problems With Images of Some Mathematics Appearing in a HyperText
Markup Language File Produced by the Combination of Programs LaTeX and
LaTeX2HTML 2012 (1.2)</P>
<P><FONT face=Arial></FONT> </P>
<P>The changes to LaTeX2HTML discussed here have kindly been previously
discussed by Shigeharu Takeno. For example, he discussed the changes to the Perl
script file latex2html at
http://tug.org/mailman/htdig/latex2html/2004-February/002688.html on the
Internet. In the file /usr/bin/latex2html I added a ? after each # in lines
16,454-16,455 as follows:</P>
<P><FONT face=Arial></FONT> </P>
<P>$math_verbatim_rx ="verbatim_mark#?math(\\d+)#";</P>
<P>$mathend_verbatim_rx ="verbatim_mark#?mathend([^#]*)#";</P>
<P><FONT face=Arial></FONT> </P>
<P>. I did not find the file latex2html.pm in LaTeX2HTML 2012 (1.2) and
therefore did not make similar modificiations within it. I left the following
line in the file /usr/share/lib/latex2html/versions/math.pl unchanged:</P>
<P><FONT face=Arial></FONT> </P>
<P>$mathend_mark = "\n${verbatim_mark}mathend000#";</P>
<P><FONT face=Arial></FONT> </P>
<P>because $mathend_mark is used several times in that file math.pl. I found
that commenting out by prepending that line of code with a # was not essential
for the successful rendering of mathematical symbols by LaTeX2HTML. And
furthermore commenting out that line of code could conceivably result in
$mathend_mark being undefined, if the lines using $mathend_mark in that file
math.pl are ever reached and if $mathend_mark is not effectively defined for the
file math.pl elsewhere within the LaTeX2HTML code. </P>
<P><FONT face=Arial></FONT> </P>
<P>And in the file /usr/lib/latex2html/l2hconf.pm I prepended line 136 with a #
as follows:</P>
<P><FONT face=Arial></FONT> </P>
<P># $DVIPSOPT= ' -Ppdf -E';</P>
<P><FONT face=Arial></FONT> </P>
<P>. The line 169 of the same file was already prepended with a # as
follows:</P>
<P><FONT face=Arial></FONT> </P>
<P># $DVIPSOPT .= " -Ppdf";</P>
<P><FONT face=Arial></FONT> </P>
<P>. I left line 151 of the same file unchanged as follows:</P>
<P><FONT face=Arial></FONT> </P>
<P>$DVIPSOPT .= " -E";</P>

<DIV><FONT size=2 face=Arial></FONT><BR></DIV>
<DIV dir=ltr>In openSUSE 12.2 I did not have the problem of the word "Image"
instead of some mathematics appearing in equation mode in HyperText Markup
Language (.html) files produced by LaTeX2HTML 1.71 that I have been reporting in
this chain of electronic-mail letters. All indications I found are that I
could not have been using TeX Live 2012 software packages in openSUSE 12.2, but
was likely using TeX Live 2011 software packages in openSUSE 12.2. On an
openSUSE Web page I read that in openSUSE 12.3 TeX Live 2012 has been split into
modularized components; evidently that is a change from openSUSE 12.2 using TeX
Live 2011 components. So I wonder if my image problem could have been
caused by using LaTeX and LaTeX2HTML 1.71 in TeX Live 2012 or else a problem
with my combined installation of 227 software packages with "texlive" or "latex"
in each of their names, for example possibly in an ls-R file not being up to
date for all of the installed TeX Live 2012 software packages (They were
probably all installed via Yet another Software Tool 2 [YaST2] in openSUSE
12.3.). By appending -w at the end of the first line of the
/usr/bin/latex2html probably Perl script file I could see what for a person who
understands the LaTeX2HTML code might well be hints of the cause of the
trouble. During "latex2html ....Throwaway28.tex" execution messages
including content like the following content appeared after "processing 16
images":<BR><BR>"Use of uninitialized value $dvi_mag in numeric gt (>) at
/usr/bin/latex2html line 4041, <LOG> 516."<BR>"Use of uninitialized value
$env" at "/usr/bin/latex2html" "line 9600".<BR><BR>Then after "Doing section

7549 of latex2html.<BR>"Use of uninitialized value" for $lbody in pattern match

line 7108, $list_class at line 7862, $2 and $1 in concatenation (.) or string at
line 8951, $2 in concatenation (.) or string at line 8771, $EXTERNAL_STYLESHEET
at line 7142.<BR><BR>I have not been able to get LaTeX2HTML 1.71 working always
as desired in any of the three states of hard-disk data dated March 21, 2013;
April 26, 2013; or July 11, 2013; of course the real problem might well be in my
TeX Live 2012 or openSUSE 12.3 software external to the LaTeX2HTML-1.71 code
itself. The TeX Live-2012 and/or LaTeX-related directory structure in
openSUSE 12.3 on my hard-disk drive for its March 21, 2013 state appears to be
/usr/share/texmf/tex/latex. Although I have only appended the -w option in
the first line of the Perl script /usr/bin/latex2html for the March 21, 2013
state of the hard-disk drive data, I suspect the "Image" problem in some
equations may be similar for all three states of the hard-disk drive
data.---Some updates to openSUSE-12.3 software and possibly one or more new
versions of the Linux kernel may have been installed in the April and/or July
states compared to the March state of the hard-disk-drive data. I think I
will restore the hard-disk-drive data to their state on July 11, 2013. I
hope that in this chain of electronic-mail letters I might have provided
sufficient clues so that someone knowledgeable of LaTeX2HTML 1.71's function can
guess both what my trouble might have been and how to remedy it; or else someone
may be able to advise me on how to further diagnose the cause of the trouble
reported here.<BR><BR>Pat<BR>

LaTeX commands for mathematics in a file called Throwaway16.tex. In the
corresponding LaTeX2HTML output file Throwaway16.html the mathematics looked
good that was produced from a LaTeX2HTML execution probably long before the

the folder Throwaway16 and the files Throwaway16.aux, Throwaway16.dvi,
Throwaway16.log, and Throwaway16.out. Then I executed latex and latex2html

LaTeX2HTML "reported" that the /tmp/l2h1004 folder would contain images.

the hard-disk drive.<BR><BR>All three files Throwaway16.tex, Throwaway17.tex,

those three, .tex files gratefully looked good in the computer program
Okular. I request diagnostic-procedural or problem-cause-guessing help in
consistently obtaining good-looking mathematics in .html (HyperText Markup

<DIV><FONT size=2><FONT face=Arial>Hello. I checked the dates of "builds"
of software packages that I have installed and with names of software packages
that LaTeX2HTML requires and found that a number of them were "built" before I
installed a working pair of LaTeX and LaTeX2HTML computer programs in an
openSUSE-12.3 Linux operating system by about March 20, 2013. For example, for
the software packages Netpbm and Perl, which LaTeX2HTML requires, the dates of
the "builds" of them that I now have installed in my Linux operating system are
earlier in time than the date of my installations of openSUSE-12.3 Linux, LaTeX,
and LaTeX2HTML which gratefully worked well together in late March of the year
2013. But yet something apparently changed in the software installed in my
openSUSE-12.3, Linux operating system between late March of the year 2013 and
early July of the same year to cause a problem for LaTeX2HTML 1.71.
</FONT><BR><FONT face=Arial>Today I provide additional information which may or
may not provide clues to why "Image" instead of "1/2" appeared in equation mode
in the .html (HyperText Markup Language) equivalent produced by LaTeX2HTML 1.71
of the LaTeX code y=\frac{1}{2}x^2. For discussion purposes here I use the
fictitious file name MyFile.tex; my actual file name is different from
MyFile.tex. As a non-root user after executing a command of the form "latex
MyFile.tex" and then a command of the form "latex2html ......... MyFile.tex," I
saw in the output</FONT><BR><FONT face=Arial>"Images will be generated in

face=Arial>And afterwards I did not find the subdirectory l2h1683 in the /tmp
directory.</FONT><BR><FONT face=Arial>Executing the command of the form
"latex2html ........ MyFile.tex" as a root user I think eliminated such error
messages. But unfortunately still the desired "1/2" did not appear in the
output, .html file in equation mode.</FONT><BR><FONT face=Arial>I unstalled the
openSUSE-12.3 software package called "latex2html" and reinstalled it using Yet
another Software Tool 2 (YaST2). Things worsened.---After a command of the form
"latex MyFile.tex" the file html.sty was reported as not found. But html.sty was
in the directory /usr/lib/texmf/tex/latex/html. So please explain how I can make
LaTeX2HTML "find" it there. Anyhow, copying html.sty from
/usr/lib/texmf/tex/latex/html to my directory in which I store .tex files and
running a command of the form "latex MyFile.tex" there was what one might call a
"workaround" solution that enabled "LaTeX2HTML" to "locate" a copy of the file
html.sty. After executing a command of the form "latex2html ...... MyFile.tex,"
the desired "1/2" in equation mode still did not appear in the produced file
with a name of the form MyFile.html. Inserting ? in each of two lines of code in
the file /usr/bin/latex2html according to
http://tug.org/mailman/htdig/latex2html/2008-December/003489.html eliminated
mathend# appearing in place of mathematics in text of the .html output
file.</FONT><BR><FONT face=Arial>I experimented and found that as a non-root
user in the Konqueror Web browser and file manager I could make a test
subdirectory and delete it. As a root user I entered the command "lsattr -d
/tmp" and obtained a result similar to "----------e-- /tmp" with the "e"
standing for "extent," meaning that files would be written in contiguous fashion
in the probably ext4 file system in which my openSUSE-12.3 partition of my
computer's hard-disk drive was written. So that result was okay. I also entered
the command "getfacl /tmp" to obtain an access control list and afterwards saw
that the /tmp directory had read, write, and execute permissions for that
directory's "Owner," for "Group", and for "Others". In addition there appeared
the line "#flags --t" in the output after entering the command "getfacl /tmp".
The "t" indicated that the "sticky bit" was set, meaning that only a root user
could delete or rename files in the directory /tmp; I assume the same thing
would apply to subdirectories of /tmp. As a root user entering the change mode
(chmod) command "chmod -t /tmp" to unset the sticky bit did not help to have
"1/2" in the .html output resulting from a command of the form "latex2html
...... MyFile.tex". So I reset the sticky bit with the command "chmod +t /tmp".
The summary of this paragraph is that I found nothing restrictive in the
ordinary or extended attributes of the directory /tmp that should have prevented
latex2html from making a subdirectory within it with a name of the form
l2h......</FONT><BR><FONT face=Arial>The image of the factor of 1/2 needed in

http://tug.org/mailman/htdig/latex2html/2008-December/003489.html on the
Internet. On the same day after making those edits my notes indicate that in a
test LaTeX2HTML produced good-looking mathematics. Checking those edits on July
8, 2013 it appeared that gratefully I made them correctly. One unusual thing is
that unlike after previous installations of openSUSE and texlive software
packages no line reading, except for the double quotation marks, " $DVIPSOPT= '
-Ppdf -E'; " was found in the file /usr/lib/latex2html/l2hconf.pm; so due to not
finding such a line of code, it was not commented out, as I had done on one or
more earlier occasions again following Shigeharu Takeno's kindly provided
advice. I have updated the openSUSE-12.3 Linux operating system, in which I have
been using LaTeX2HTML 1.71, numerous times since March 20, 2013, most recently
on July 7, 2013.<BR>But on July 8, 2013, while running a "latex2html ......"
command on a .tex file, I observed I think a new phenomenon for me (A "latex
....tex" command had already been executed by that time.). After seeing the
message reading something like "processing 192 images," unlike what I had seen
in the past when processing a new, .tex document, I did not see the image
numbers appearing one per line in a terminal program as those images were being
processed as the result of a "latex2html...." command being executed. Then
afterward when attempting to view the .html document produced by LaTeX2HTML 1.71
I saw inline mathematical images within a paragraph of text displayed correctly.
But following that success in the .html file unfortunately I saw some parts of
equations appearing in each failed case as "Image" in my installation of the
Konqueror Web browser (The problem was also observed in a Mozilla Firefox Web
browser.). For example, in the test equation y=(1/2) x**2, with LaTeX code for
it appearing as y=\frac{1}{2}x^2, x squared was displayed correctly in equation
mode; but for the fraction of one-half instead the word "Image" appeared on what
looked something like a software "button." Looking in the folder in which
LaTeX2HTML produced the .html output file in one case many Portable Network
Graphics (.png) files were there. In a different test case I tried to inspect a
.png image file using the program GNU (GNU's Not Unix) Image Manipulation
Program (GIMP) and saw the word "Image," but otherwise did not see "1/2" or a
portion of an equation. So apparently such images were not completely produced
by LaTeX2HTML for a very general reason I later hypothesize here. Unfortunately
this "Image" problem occurred when processing both an old and a new .tex file
using probably the combination of the programs LaTeX and LaTeX2HTML. On the
other hand, when the DeVice-Independent (.dvi) output file produced by LaTeX was
viewed in the program Okular, the sampled equations looked good.<BR>In summary,
this matter appears complicated because of the many software packages installed
in my Linux operating system. But I think I used LaTeX2HTML version 1.71 even
before my installation of the openSUSE-12.3 Linux operating system and do not
recall ever seeing this exact problem before July 8, 2013. And shortly after the
installation of openSUSE 12.3 and some "texlive" software packages and making
some updates to software packages within the openSUSE-12.3 system, the programs
LaTeX and LaTeX2THML worked okay. My subsequent edits of two lines of code in
the file /usr/bin/latex2hml gratefully appear to have been properly made. So a
simple hypothesis is that the "Image" problem might have been caused by one or
more of the many updates to software packages in openSUSE 12.3 that I have made
through Yet Another Software Tool 2 (YaST2) since March 20, 2013. I do have a
file called images.log in the .html file's output directory that contains about
349 lines for a test case. Perhaps there could be a clue to the problem within
that file. I request that someone please either make a good guess for me of the
cause and solution to this problem or else provide for me a diagnostic means by
which I could hopefully determine the cause of this problem, such as to look for
a certain kind of clue in the file images.log.
