Set-up MariaDB library file location programmatically?

Is there anything you need from me in terms of information?
This is from the folder:

Thank you, do you have a link that details how?
I'm downloading the MariaDB ODBC driver for MAC now or is this not the same?

@jsulm , thank you.
So already I'm struggling with the answer on: https://stackoverflow.com/questions/6483523/qt-how-to-getcompile-mysql-driver
I cannot find the driver sources, my Qt path looks like this:
/Users/simonplatten/qt/5.14.2/SrcThere is no plugins folder in there, the only plugins folder is:
/Users/simonplatten/qt/5.14.2/clang_64/pluginsThat doesn't contain a mysql folder. I just did:
sudo find / -name sqldrivers/mysqlNothing was found on my system.
I've tried to follow the instructions on https://doc.qt.io/qt-5/sql-driver.html#qmysql
I fall at the first hurdle, I don't have the environment variable QTDIR set and I think my installation of MariaDB is complicated by the fact it was installed using Homebrew.Kind Regards,

Did you install Qt sources?

how do I do that?
If you used online installer you can use Maintenance Tool...

@jsulm , I did exactly that before posting my reply, I didn't see any option in it for source code.

@jsulm , I'm confused now, the link posted is to the Open source page. What if I don't intend my application to be open source, once its completed I intend to purchase a license before distribution. Can I build a mySQL driver for Qt without open source?
Kind Regards,

I'm not sure QtCompany will agree with that.
You should contact them.There are many ways to get the source code. For example here: https://download.qt.io/archive/qt/5.15/5.15.0/single/
Or using Git as described here: https://wiki.qt.io/Get_the_Source -
Hi, it might be easier if you use Qt's ODBC plugin (libqsqlodbc.dylib) together with the MariaDB Connector/ODBC
-
@hskoglund , thank you, I'll look into it. It seems its available for just about every operating system except MAC.
-
@jsulm , if I'm developing it on my own system and no one else is involved or using it, how would this be against any license?
@SPlatten I'm not a lawyer and not working for QtCompany (that's why I suggested to ask the company).
You say: you are now developing an app and you want to release it later as closed source. And you want to buy Qt license when you want to release the app. My point was: QtCompany could say that you actually need the commercial license from the beginning as you're developing a closed source application which is going to be distributed. I may be wrong here, but it is worth checking.If you're not going to distribute your app then there is no issue.

@jsulm , thank you, I'll send Qt an email. Contacting Qt to ask such a question is easier said than done...How do I contact the appropriate person or department in Qt to ask?

Query sent to Qt.

I realize this is probably not your issue here, but I think you ought be aware, at least for future searches, that
-name abc/def--- with that/--- will always return false, so you'll never find a match.On MacOS (I'm Ubuntu) I think you'll find you would have to use
-pathinstead, plus you want a substring match, so you would need e.g.:sudo find / -path '*sqldrivers/mysql' -printP.S.
Don't forget the-printwhich you didn't show you used, elsefindis remarkably silent ;-) -

You do, or at least the QtC want you to, I had the issue when I wanted to open source a project that was previously made under QtLicence, slightly different but that exact topic came up.
It's due to the yearly licensing
scamscheme, would be no issue at all if it was a one purchase last for ever kind of deal -
