ZSH (CVS) configure problem?

ZSH (CVS) configure problem?

[Helmut Jarausch]

Hi,

I've tried to build zsh (from CVS) with the "multibyte" configure
option. But in that case, the linker fails because it now needs
-lncursesw -ldl  instead of just -lncurses.
The build without this options ran just fine.

Thanks for ZSH (as ever)

I don't understand what you're saying; configure doesn't search ncursesw
unless you tell it to.  Do you mean configure is finding ncurses but
linking is failing at some point?  Also, multibyte mode is now handled
automatically if it's avilable:  what options are you changing that cause
it to fail?  Could you say

- what arguments you're passing to configure
- what libraries configure is coming up with
- what error is being produced during building.

Thanks.

I'm using a GenToo ebuild which amounts to
	econf \
		--bindir=/bin \
		--libdir=/usr/$(get_libdir) \
		--enable-etcdir=/etc/zsh \
		--enable-zshenv=/etc/zsh/zshenv \
		--enable-zlogin=/etc/zsh/zlogin \
		--enable-zlogout=/etc/zsh/zlogout \
		--enable-zprofile=/etc/zsh/zprofile \
		--enable-zshrc=/etc/zsh/zshrc \
		--enable-fndir=/usr/share/zsh/${PV%_*}/functions \
		--enable-site-fndir=/usr/share/zsh/site-functions \
		--enable-function-subdirs \
		--enable-ldflags="${LDFLAGS}" \
		--with-tcsetpgrp \
		--with-curses-terminfo \
		--with-maildir-support \
		--with-pcre \
		--with-cap \
		--with-multibyte

The final link links the library -lncurses and fails because external
references ( I don't remember the 4 names ? add_wch) couldn't be
resolved. Linking to -lncursesw -ldl, instead, was successful.
For the moment I've stepped back to not using --with-multibyte .

Many thanks,
Helmut.

That's probably --enable-multibyte or it won't have an effect.

This seems to be different from other Linux systems where the
appropriate bits are in ncurses.

It sounds like we need to be searching for ncursesw, a subject that's
come up before a propos of MacOS (and I was asking about at the start of
the week).  Clint thinks in that case we need -I/usr/include/ncursesw,
so it may not be entirely trivial.

The dl library should be picked up later if it's needed, but that won't
work if it's causing linking with ncursesw to fail.

Clint probably was mistaken, since the headers in /usr/include/ncursesw
include <ncurses/$otherheader>.
