Bug 607890 – dev-tex/latex2html-2017.2: Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at /usr/lib64/latex2html/styles/natbib.perl line 1454, <STYLES> line 4.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

Thanks for the upgrade to 2017.2!
Problem with using natbib...
It seems that upstream has the defined(@array) problem in yet more places :-(

when does this happen ?

the patch changes specifically this like, does it happen if you upgrade latex2html first ?

I'm not sure what you mean. Of course I upgraded to latex2html-2017.2 first. /usr/lib64/latex2html/styles/natbib.perl with the offending line

if (defined @$style) {

belongs to the package and, of course, is invoked if the LaTeX package "natbib" is used in the translated .tex file.

If you mean the patch for the previous error
https://bugs.gentoo.org/show_bug.cgi?id=604184 -
that one was in versions/frame.pl and there it was patched...

mine looks like this:

    local($style)="citestyle_$2";
    if (@$style) {
        ($CITE_OPEN_DELIM,
         $CITE_CLOSE_DELIM,
         $CITE_ENUM,
  


and the latex2html-tests.patch applied by the ebuild indeed patches this:

Okay, after today's update (and I may be up to 1 day delayed since I update from deltas) it is fixed here too. Could it be that a previous version of latex2html-tests.patch did not contain the natbib patch and landed in the previous delta?

Anyway, marking "Resolved" now, thanks!
