Re: [Evolution-hackers] Compile Evolution Mail as .so file with API for other GUI on ARM device

["Michal G." <guziemic spam gmail com>]

Hi,

Nice to meet the author of Anjal :)

I went through code and Wiki yesterday and I am starting to understand just a little piece of very high architecture.
I will try to compile EDS with my SDK for my ARM device. But first I need to familiarize with build process.

As I understand within EDS there is mail engine - this Camel library which I could use and link dynamically with my GUI.
Do you know if there is simple example that shows how to send email message?

Probably better way will be to use your e-mail-factory. Then I will be able to split GUI and Mail engine on two different processes.
Will your e-mail factory be an official part of Evolution soon?

I do not understand why you advice me to checkout branch of evolution. I thought that all data engines (mail and calendar) are covered by EDS.
And when I compile it I will be able to connect it with my GUI. It could be done over DBUS if I have two processes or just dynamic linking to GUI.
Do I think correctly?

Could you say, point me a document that describe how EDS store mails and calendar data. Is it some own database in file or some other mechanism?

Calendar is already in EDS available over DBUS.

I was the author of Anjal. It was build with Gtk/Cairo on top of
libevolution-mail. Now after mbarnes's awesome library breaks, I broke
mail engine to a independent library that can reside in EDS (in the
future) which I currently server over DBUS.

You must checkout master branch of eds and evolution.
https://github.com/sragavan/e-mail-factory is the dbus engine that Im
working on, which is still under development. Some apis are fun and
still not up to the mark. But you can use them and it works fine.
