efax-gtk is the front-end of efax

http://www.cce.com/efax/

Part-2

Setup of fax machine on a Linux box,

Arch Linux

Part-1

Installing efax-gtk

package:- efax-gtk-3.0.12-1 in the AUR

https://aur.archlinux.org/packages.php?ID=6884

It needs following dependencies

glibc

gtk2

libsigc++2.0

Other packages required

cups 1.3.6-1

libcups 1.3.6-1

libgnomecups 0.2.3-1

To check whether the aforementioned dependencies are already running on the Arch Linux box;

$ pacman -Qs glibc

local/glibc 2.7-7 (base)
GNU C Library
local/nss-mdns 0.10-1
glibc plugin providing host name resolution via mDNS

$ pacman -Qs gtk2

local/gtk-sharp-2 2.10.2-1
gtk2 bindings for C#
local/gtk2 2.12.8-1
The GTK+ Toolkit (v2)

$ pacman -Qs libsigc++

local/libsigc++2.0 2.1.1-1
Libsigc++ implements a full callback system for use in widget libraries - V2

They are already running on the Arch Linux box.

$ sudo nano /etc/makepkg.conf

set PKGDEST as;

PKGDEST=/home/user/efax-gtk

Creating the prebuild package

$ cd /home/user

$ wget https://aur.archlinux.org/packages/efax-gtk/efax-gtk.tar.gz

$ tar zxpf efax-gtk.tar.gz

$ cd efax-gtk

$ ls
