[SOLVED]MySQL library problem

[SGaist]

@mcosta not it doesn't, macdeployqt parses the output of otool to get the dependencies of the libraries/plugins of Qt. AFAICT, the plugins are built with dependencies coming from MacPorts hence the libmysqlclient.18.dylib in /opt/local/lib/

[SGaist]

Which version of OS X and Qt are you using ?

I've corrected the example line

@SGaist

OS X 10.10.3
QT 5.4

You're missing a slash before Users

@SGaist
Now i got only Postgre error

ERROR: no file at "/usr/local/lib/libpq.5.dylib"

Does it mean that i have working mysql plugin?

[SGaist]

You should, unless the libmysqlclient is very different from the one Qt was built with.

[cpuin]

I have now mysql working, but i still can't have working app because of this:
ERROR: no file at "/usr/local/lib/libpq.5.dylib"

This is not very good approach: include all plug-ins w/out need of them.

[SGaist]

That's the PostgreSQL plugin. Like I suggested before, just remove the plugins you don't need from your bundle.

[cpuin]

@SGaist

As i answered before when removing all other plugins from the bundle, the app doesn't open!

[SGaist]

I didn't suggest to remove all other plugins, just the SQL related plugins you don't use

[cpuin]

@SGaist Exactly, i left only sqlite plugin and the app doesn't open

[SGaist]

Start it from the command line, what does it tell you ?

[cpuin]

@SGaist Strangely the ERROR disappear and working app bundle was created w/out changing anything.Unfortunately the app created database.db in the path i set (in this case in the program.app/contents/MacOS but can't write inside!

Starting the app from QT can write in to the db, but starting it outside Qt doesn't write, but creates it.

[SGaist]

You need to use a writable path (look at QStandardPaths) Writing in the bundle itself is not something to do and it's even prohibited if you use the App Store to distribute your application.

@SGaist

Do you tell me that Qt Desktop application can be submitted in Apple App Store?As i know they don't allowed external frameworks?

[SGaist]

Yes, you can, they have restriction but no, external frameworks are not prohibited.
