Description Kathrin 2014-12-22 13:29:11 UTC 
Hi, 
I just installed digikam on the weekend but couldn't get the mysql database to work, on start-up I get an error saying:

"The database it not valid: the "DBVersion" setting does not exist. The current database schema version cannot be verified. Try to start with an empty database."

Well, it is empty though, I just created it. Here are my steps:

- mysql runs on Windows 7 server
- I installed digikam with macports on MacOSX (10.9.5)
- for the mysql databases I used the following commands:

(my user is "digikam", database is also called "digikam")
CREATE DATABASE digikam;
GRANT ALL ON digikam.* TO digikam WITH GRANT OPTION;
USE digikam;
GRANT ALL ON digikam TO digikam WITH GRANT OPTION;
GRANT CREATE ON digikam TO digikam WITH GRANT OPTION; 
FLUSH PRIVILEGES;
... and the same for the database "thumbs"

Settings within digikam are ok, since the network test is working.
(user, port, passwort, ip everything correct)

Can anyone help me? Digikam is just about my last resort, we have a private network at home while using both windows machines and a mac with our server which stores our media files. I have been desperately searching for a picture archiving solution that supports network databases as well as windows / mac clients. so if there is no solution to my problem, maybe someone can point me to an alternative.

thank you!

Reproducible: Always

Steps to Reproduce:
see above:
1. use the mentioned steps to create the databases
2. enter the information in digikam
3. hit enter ;-)

Actual Results:  
see above: message on startup: "The database it not valid: the "DBVersion" setting does not exist. The current database schema version cannot be verified. Try to start with an empty database."
after confirming the message on startup and re-entering the preferences and confirming the dialogue with ok, no message pops up.

Expected Results:  
I would have expected that the databases could be used :)

mysql on windows 7
digikam on osx with macports

I've a similar problem with Win ver 4.50, digiKam does not get past the flash-screen and 'Reading Database' message without crashing.  After a long pause it comes up with the following error message:

Application: digiKam (digikam.exe), signal: EXCEPTION_ACCESS_VIOLATION

ntdll.dll!ZwRaiseException() [[unknown] @ -1] at 0x773515ee


Fault repeatable every time, same again on clean reinstall (with old pgm folder removed etc.).

----------

Machine:  Win 7-64-bit / 8GB RAM.

I have the same issue with the internal mysql server on Mac OS X (using MariaDB 5.5.39) as well as on Linux (also using MariaDB).

I know MySQL support is supposedly experimental, but this feels like a couple of steps before experimental ...
Comment 3 caulier.gilles 2015-06-22 19:26:18 UTC 
New digiKam 4.11.0 is available with official PKG installer for OSX.

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?

Indeed, as can be expected from the exchange above.
