Bugzilla Bug 143831

latex2html seems to somehow expect perl 5.8.6, after i upgraded perl it dies
with an error saying it cant find perl5.8.6 ... then when i symlinked
perl5.8.6->perl for a quick test, i get the error below. urgs, this is a nice
little tool i dont want to miss, i dont have any perl knowledge whatsoever
though so i cant really fix it myself (although i assume it would be a trivial
thing). any takers? anything i could provide to make fixing easier? (i'm just
going back to perl 5.8.7 to see if that works)

mmh i downgraded to perl5.8.7, run perl-cleaner, reemerged latex2html - no go,
same problem :(

now if someone could point me to the old 5.8.6 ebuild that would be nice, so i
can check if its actually perl or my specific system which is the problem :/

ok one more, its becoming weird and confusing :=P i grabbed the old 5.8.6
ebuild and patches from cvs and emerged 5.8.6, perl-cleaner, and emerge
latex2html again - and it STILL does not work. thats completely strange coz i
have used the thing fine before with exactly this config.

fortunatly though with the help of someone else who knows perl i could track
down the problem to a single line in /usr/lib/latex2html.pl, and also could fix
it trivially.

line 94 is originally

if (undefined (&convert_length)) { sub convert_length
{&convert_length_table(@_)} }

what it complains about is the "undefined" function not beeing defined.
changing this into "!defined" fixes it. is this some kind of perl feature that
was silently removed? or is some dependend perl module that provides it missing
in the latex2html ebuild?

that said, i'll now go back to the latest stable 5.8.8 and see if latex2html
works there with the above fix

last one...

a) typo, the file in question was /usr/lib/latex2html/versions/table.pl

b) it works in 5.8.8 aswell with the above fix, craps out without it.

Confirm that groepaz's analysis is correct. Working on a patch and updated
ebuild.

The updated ebuild that applies the no undefined perl function patch

This ebuild applies a new patch that should fix the call to the deprecated
"undefined" function from the latex2html table.pl script.

This patch fixes a call to a depreacted perl function in table.pl

This patch will fix the breakage that occurs in r1 from the call in
versions/table.pl. Changes from deprecated if( undefined(...)) to
if(!defined(...))

Sample .tex file found on the internet to use for testing

A file that can be used to test latex2html.

Also latex2html is stable on amd64 with perl 5.8.8.

Successful build on amd64 as well here

Builds and successful minimal test with
dev-tex/latex2html-2002.2.1_pre20041025-r1.

applied, thanks
