Description Cyp 2020-01-15 09:31:33 UTC

dev-tex/chktex-1.7.6 with +doc fails. With -doc, it works.

make -j8 html 
rm -r HTML
rm: cannot remove 'HTML': No such file or directory
make: [Makefile:212: html] Error 1 (ignored)
/usr/bin/mkdir -p HTML
/usr/bin/perl ./MakeHTML.pl ChkTeX.tex > HTML/ChkTeX.tex
cd HTML; /usr/bin/latex2html ChkTeX.tex
Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/((^|[\s,=])')\\\W{ <-- HERE (\w)}/ at /usr/lib64/latex2html/latex2html.pl line 6456.
Compilation failed in require at /usr/bin/latex2html line 39.
make: *** [Makefile:215: html] Error 2

Based on bug 414455, I tried reemerging dev-tex/latex2html-2015, which failed. Using the workaround in bug 636344, I managed to reemerge latex2html, but it didn't help with chktex.

I haven't tried downgrading dev-lang/perl-5.30.1, but “Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30)” in bug 636344 looks relevant.

I get the same error using dev-lang/perl-5.28.2-r1
