syncml-plugin.so: undefined symbol: osync_db_query

[Christian Hilgers-2]

Hi all,


After doing the test with the different libsyncml libs msynctool
does no longer shows the syncml plugins.


This is msynctool version "0.36"
using OpenSync version "0.36"
Available plugins:
kdepim-sync
palm-sync
file-sync


In the trace (attached) the problem is visible here:

Is libopensync.so a symlink to libopensync.so.1?

Please, let me know if this works for you.

Thanks for testing!

confirmed:

This is msynctool version "0.36"
using OpenSync version "0.36"
checking the plugins visible:
Available plugins:
kdepim-sync
palm-sync
file-sync
syncml-http-server
syncml-http-client
syncml-obex-client


Thanks

I noticed your comment in SVN. My idea was that I don't want to create a
new explicit dependency to SQLite including own native code if the
framework already implemented a wrapper for the database. I don't
checked if the interface is exported.

Best regards

Michael

Actually i did a mistake, because setting the symbol visbility to linker flags
instead of compiler flags. So everything got exported...

The problem I see, is "maintaing" this BIG API... we may split some stuff in
different shared objects. One shared library for the frontend (the engine
stuff), one for plugins and extra helpers for plugins (timer, ane other
stuff).

We have approx. 800 exported symbols right now...

So we don't break the dependecy for the frontends all the time, which is quite
annoying for frontend developers.

What do you think?

Btw. for what do you need osync_db for SyncML plugin? Capabilities should get
stored via the capabiliteis interface while performing the disocvery call.
Everything else should be handled by Anchor database...

The use of database should be reducded as possible, since it's quite slow...
for each QUERY a "sync" got called.

I have no problem with more libraries to make them easier to manage. The
only problem is what does management mean?

The capabilities are far away from being perfect and we cannot map
ical/vcal 100% perfect because the standards are simply not compliant.
So I need a way to cache the devinf stuff without depending on the
capabilities and without losing informations. Therefore I decided to use
a SQLite database to cache the informations.

Additionally this cache helps to find problems like missing photos.
