[Pkg-zsh-devel] Bug#993539: Bug#993539: "functions/Misc.zwc" isn't compiled from the bundled source files

[Leo Gama]

[image: image.gif][image: image.gif]Hi, Axel.

Thanks for the prompt response.

Hrm, yes, but this is caused by this sed call in debian/rules:


  # Doesn't this need to go before we zcompile stuff into .zwc files? --
Axel
        sed -i -e 's,^local HELPDIR=.*,local
HELPDIR=$${HELPDIR:-/usr/share/zsh/help},;
s,:-more,:-/usr/bin/pager,;' \
                debian/zsh-common/usr/share/zsh/functions/Misc/run-help
        sed -i -e '1!b;s:^#!.*[ /]zsh:#!/bin/zsh:;s#/usr/local/bin#/usr/bin#;'
\
                `find debian/zsh-common/usr/share/zsh/functions -type f`

Oh, I see it now. Maybe I even read this comment, but before understanding
what was going on, so haven't got my attention.

For the fix, is it possible to edit the 'configure' file that sets the
'runhelpdir' variable before compilation? The path is not hardcoded in the
'run-help' source file. Something in the lines of:

sed -i -e "s,/'\$${VERSION}'/,/," configure


or even

sed -i -e 's,/[^/]\+/\(functions\|help\),/\1,' configure



Best,
Leonardo Gama
