@KroMignon , excellent, thank you.

excellent, thank you.

your welcome

[SPlatten]

@KroMignon , now it all appears to have built without any issues, I'm using source that I wrote on my iMAC when doing the same thing, have put in the database details using driver name QMYSQL, but when I try to connect I get the output:

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

[JonB]

@SPlatten
Whenever you get QMYSQL driver not loaded, start by setting environment variable QT_DEBUG_PLUGINS=1, run application, look at diagnostic output, especially at end.

[SPlatten]

@JonB said in Building database driver, IT difficulties:

QT_DEBUG_PLUGINS

Thats easier said than done, on this system I cannot set environment variables....

[KroMignon]

@SPlatten said in Building database driver, IT difficulties:

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

I guess the mysql-connector dynamic library (libmysql.dll) is not in your path

[JonB]

@SPlatten said in Building database driver, IT difficulties:

Thats easier said than done, on this system I cannot set environment variables....

That is an unusual statement, I have not heard of such a system. You will have problems if you cannot set environment variables....

You should be able to do so. Even if you have to write a one-line "wrapper" program....

[KroMignon]

@SPlatten said in Building database driver, IT difficulties:

Thats easier said than done, on this system I cannot set environment variables....

You can do it with Qt-Creator: Projects / Build & Run, Select "Run", than in "Run Settings"/Environment you can add as many environment variable as you want => cf. https://doc.qt.io/qtcreator/creator-project-settings-environment.html

[SPlatten]

@JonB , tell me about it, please read the first post on this thread for more information.

[JonB]

@SPlatten
If you mean

I cannot modify system environment variables

there is no need to set a system variable, only an environment variable for the duration of running your program. Either in a Command Prompt, or as @KroMignon wrote in Qt Creator if you are running from there. Or in a .bat script, or in a one-line "wrapper" C/C++ program. heck, you're running nmake, that I believe sets environment variables, you could even do so from there....

And, depending on when Qt produces that runtime error, if it's on the statement which creates a QSqlDatabase, as I think it might be, then you can just set the environment variable in the Qt program you are writing beforehand.

[SPlatten]

@JonB , setting an environment variable doesn't help when Qt Creator is running at the system level. Any environment variable added to the console, is only visible to the environment of the console.

[JonB]

@SPlatten
I have tried to show you a number of places you can set the environment variable. If you really say you cannot from Qt Creator (I don't understand why not and I don't understand what you are saying), try any of the others....

[KroMignon]

@SPlatten said in Building database driver, IT difficulties:

Have you only try it out?
Based on your first post on this thread, you are using Qt Creator 4.4.1.
Settings environment variables with QtCreator works for me, on any system I am using (WindowsXP/7/10 and Linux).
So I cannot imagine it will not work for you.

[SPlatten]

@KroMignon , just created the variable and verified that it is there using EXPORT, rebuilt project in Qt Creator and executed, no new / additional output in Application Output and the console just contains:

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

[JonB]

@SPlatten
What is the name of the environment variable, and what is its value?

[KroMignon]

@SPlatten said in Building database driver, IT difficulties:

just created the variable and verified that it is there using EXPORT, rebuilt project in Qt Creator and executed, no new / additional output in Application Output and the console just contains:

You don't have to recompile your application, just setup the environment variable for you project

And the run the application with F5 or Ctrl+R, that's it.

But as I have written before, I am quiet sure your problem is that the mysql-connector dynamic library is not in your path.
The easiest way to solve this is to copy libmysql.dll in to Qt lib path, which should be for Qt 5.9.2 ==> C:\Qt\5.9.2\msvc2015\bin\

@KroMignon thank you...again!

It looks like your are running debug version, but did not build plugin for debug, only release build is done.
I think you have to (re)build mysql plugin and add "CONFIG+=debug" to ensure building version of plugin.
Something like:

qmake "CONFIG+=debug" -- MYSQL_INCDIR=c:/mysql-connector-6.1.5/include MYSQL_LIBDIR=c:/mysql-connector-6.1.5/lib
