Hi all,
I am trying to do an ebuild for xzoom. It is a nice application that magnify part of X display, with real-time updates, much better as xmag.

When installing it by hand, with just:
Code:
xmkmf -a
make
su -c "make install"

the program is working just fine.

When installing it with the following ebuild:
Code:
# Copyright 1999-2006 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $

IUSE=""

inherit

RESTRICT="nomirror"

DESCRIPTION="Magnify part of X display, with real-time updates."
# Not sure, but it look like it doesn't have any homepage, so use the Debian devel page
HOMEPAGE="http://packages.qa.debian.org/x/xzoom.html"
SRC_URI="http://ftp.debian.org/debian/pool/main/x/xzoom/${PN}_${PV}.orig.tar.gz"

LICENSE="as-is"
SLOT="0"
KEYWORDS="~x86"

DEPEND="x11-misc/imake
        x11-libs/libX11
        x11-libs/libXext
        x11-libs/libXt
        x11-libs/libICE
        x11-libs/libSM
        x11-base/xorg-x11"

S="${WORKDIR}/${P}.orig"

src_compile() {
        cd ${S}
        xmkmf -a
        sed -i -e 's:/usr/local/bin:/usr/X11R6/bin:' Makefile || die "sed failed"

        emake DESTDIR="${D}/usr" || die "Compilation failed"
}

src_install() {
        emake DESTDIR="${D}" install || die "Installation failed"
        dodoc README
        mv xzoom.man xzoom.1
        doman xzoom.1
}

I get the following error and the program doesn't start:
Code:
$ xzoom
xzoom: can work only with 8 bits/pixel

What can I do?

Hi,

I want to work at pixel level for some job and can't find a magnifying tool in ebuilds except, may be orca ( https://packages.gentoo.org/packages/app-accessibility/orca ) or Compiz but I don't want to install Braille and a Braille server or Compiz just to have a small zoom tool (EDIT : and just notice Xmag in portage, but effectively Xzoom is better for what I do).

It seems a patch is needed to avoid the error message, but I don't know how to modify ebuild to include it :

Code:
$ xzoom
xzoom: can work only with 8 bits/pixel


On an amd64 without the patch, even when building from sources, you also have the error message at run ...
But ...

Code:
patch -Np1 < xzoom_0.3-23.diff
patching file Imakefile
patching file scale.h
patching file xzoom.c
patching file xzoom.man
patching file debian/copyright
patching file debian/compat
patching file debian/watch
patching file debian/changelog
patching file debian/rules
patching file debian/control
patching file debian/menu


Do the job ...

Ref. : https://aur.archlinux.org/packages/xzoom/
Patch : ftp://ftp.acc.umu.se/mirror/cdimage/snapshot/Debian/pool/main/x/xzoom/xzoom_0.3-23.diff.gz
Xzoom sources : http://webdiis.unizar.es/pub/unix/X11/xzoom-0.3.tgz


Sorry for my english, and for post diging but if it can help. Later is better than never ;-)
