Evolution is the integrated mail, calendar and address book
distributed suite from Helix Code, Inc.

See http://www.helixcode.com/apps/evolution.php3 for more information.

Note that Evolution is still beta. This means it may delete all of
your mail if you give it the chance.

If you are interested in hacking on Evolution, you should subscribe to
the Evolution mailing list. Send mail to
"evolution-request@helixcode.com" with the word "subscribe" in the
body of the message. If you are planning to work on any part of
Evolution, please send mail to the mailing list first, to avoid
duplicated effort (and to make sure that you aren't basing your work
on interfaces that are expected to change).

There is a mailing list archive available at
http://lists.helixcode.com/archives/public/evolution/

There is also an #evolution IRC channel on irc.gnome.org.


IF IT DOESN'T WORK
------------------

Did you read the "How to build" section below? :-)

If you have built Evolution and it doesn't work, or you can't get it
or one of its dependencies to compile, try running the
"verify-evolution-install.sh" script in the tools/ subdirectory. It
may be able to figure out what went wrong.


HOW TO BUILD EVOLUTION
----------------------

	*** READ THIS BEFORE YOU START BUILDING ANYTHING! ***

Evolution depends on a large number of unreleased and rapidly-changing
libraries. Some of these libraries in turn depend on other unreleased
and rapidly-changing libraries.

Building Evolution is HARD, and it's going to stay hard until all of
the libraries it depends on stabilize, and there's nothing we can do
to make it any easier until then.


General Principles
------------------

First you have to decide whether you want to install Evolution (and
its dependencies) into the same prefix as the rest of your GNOME
install, or into a new prefix. Installing everything into the same
prefix as the rest of your GNOME install will make it much easier to
build and run programs, but may make it harder to uninstall later.

If you want to install into the same prefix as the rest of GNOME,
type:

	gnome-config --prefix
	gnome-config --sysconfdir

and remember the answers, and pass them to "configure" and "autogen"
when building the other packages you need. Eg:

	./configure --prefix=/usr --sysconfdir=/etc


If you do not do this, you will need to set the GNOME_PATH environment
variable (and ACLOCAL_FLAGS as well if building from CVS) to include
the prefix you install into. Eg:

        export GNOME_PATH=/usr/local
	export ACLOCAL_FLAGS="-I /usr/local/share/aclocal"

(Assuming your shell is bash, and you installed into /usr/local.) You
need to set GNOME_PATH both during compiling AND when you run
evolution. Remember also that if you're installing into an odd prefix
such as /evolution, that you also need to make sure to put
${prefix}/bin in your PATH.

If you install Evolution into a different prefix from OAF, you will
also need to set OAF_INFO_PATH to include the directory where the
oafinfo files are installed (${prefix}/share/oaf). (OAF will
eventually obey the GNOME_PATH variable, but it does not do so
currently.) Eg:

	export OAF_INFO_PATH=/usr/local/share/oaf

If you are already running an oafd, you will need to kill it after
setting that variable so it gets restarted later with that in its
environment.


Dependencies
------------

All of these libraries are available in GNOME CVS, under the given
names. Most (but not all) of them are also available as tarballs on
ftp.gnome.org. The (*)ed packages are available in Helix GNOME.
(http://www.helixcode.com/desktop/)

 - gnome-xml - 1.8.7 or later in the 1.0 series, but not from the 2.0
   series (If you get this from GNOME CVS, use the tag "LIB_XML_1_X".)
   (*)

 - gnome-print - 0.20 (*). The gnome-print CVS HEAD will NOT work, nor
   will 0.21.

 - gdk-pixbuf - 0.7.0 or later (*)

 - ORBit - 0.5.3 or later (*)

 - oaf - 0.5 or later

   *** If you are using oaf from CVS, you should use the flag
   *** "--disable-more-warnings" when configure, or it may fail to
   *** build.

 - gnome-vfs - 0.3 or later

   *** If you are using gnome-vfs from CVS, you should use the flag
   *** "--disable-more-warnings" when configuring, or it may fail to
   *** build.

 - bonobo - 0.17 or later

   *** Note that bonobo must be installed with the same --prefix as
   *** either gnome-libs or evolution for the Makefiles to work
   *** properly.

 - libunicode - 0.4 or later, available from
   http://www.pango.org/download.shtml

 - gconf - 0.6 or later

 - gal (GNOME Application Library) - from CVS

 - gtkhtml - 0.5 or later

 - libglade (*)

If you want support for PalmPilot syncing (currently only supported by
the calendar and not yet very stable/functional), you will also need
the following packages:

 - pilot-link (*)

 - gnome-pilot - from CVS, with --enable-oaf
