QMYSQL driver not loaded and Library mysql is not defined

[Christian Ehrlicher]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

Did I misunderstood what you called wrong directory?

Yes. You have to call it in the sqldrivers directory as shown in the documentation.

[Markyo]

@Christian-Ehrlicher Ok so update!
I'm doing this:

C:\Qt\5.12.11\msvc2017\bin\qmake.exe -- MYSQL_INCDIR="C:\Program Files\MySQL\MySQL Connector C 6.1\include" MYSQL_LIBDIR="C:\Program Files\MySQL\MySQL Connector C 6.1\lib"

get this:

Running configuration tests...
Done running configuration tests.

Configure summary:

Qt Sql Drivers:
  DB2 (IBM) .............................. no
  InterBase .............................. no
  MySql .................................. no
  OCI (Oracle) ........................... no
  ODBC ................................... no
  PostgreSQL ............................. no
  SQLite2 ................................ no
  SQLite ................................. yes
    Using system provided SQLite ......... no
  TDS (Sybase) ........................... no

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'C:\Qt\5.12.11\msvc2017'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

Then, I run nmake:

I checked the config.log, as said in the doc, and lines talking about mysql are:

I tried to delete config.cache as said in doc, but same results..

And of course, while trying to run my app:

QML debugging is enabled. Only use this in a safe environment.
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC QODBC3 QPSQL QPSQL7

Honnestly I'm kinda lost in technical informations..

[jsulm]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

MySql .................................. no

As you can see MySql was disabled.
Check the config.log file to see why.

[Markyo]

@jsulm I thought it was the already installed ones.
I've put the part about mysql from the config.log in my previous message, but I will link the whole file bellow.

[jsulm]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib : warning LNK4272: type d'ordinateur bibliothŠque 'x64' en conflit avec le type d'ordinateur cible 'x86'

This is the problem: your Qt and MySql lib are for different architectures.

[Markyo]

@jsulm x64 vs x86?
Is there a way to solve this? Installing both in the same architectures? Wich one should I choose?

[jsulm]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

Wich one should I choose?

The one you need.
It looks like you installed Qt x86, right? Install Qt x86_64 and use that one.

[Markyo]

@jsulm to install this version, should I use the qt-unified-windows-x86-4.1.1-online.exe? and untick all x86 components in custom installation?
Or is there an x86_64 installer?

[jsulm]

@Markyo Since you already installed x86 Qt simply start the Qt Maintenance Tool and deselct the x86 version and select x86_64 one.

[Markyo]

@jsulm While waiting to be able to repost, I uninstalled my qt..
So right now, I'm on this page:

As you can see, I've unticked the x86 in version I want, is it ok? Plus, is there some things to tick?

[jsulm]

@Markyo Why did you install everything?! Do you really need all these Qt versions?
What compiler do you want to use? Select only Qt for the compiler you want to use...
Also, you did not unticked the MSVC and MINGW x86 versions.

[Markyo]

@jsulm I don't know, I thought I had to to install the correct version.
What do you mean about MSVC and MINGW x86? isn't there only 32 and 64?
And for the compiler, honestly I don't know, I think it is the visual studio one, but not sure.

[jsulm]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

isn't there only 32 and 64?

x86 IS 32bit and x86_64 is 64bit.
Please check what Visual Studio you have and install 64bit Qt version for that Visual Studio version.

[Markyo]

@jsulm Oh ok I understand!
My visual studio is 2019 version 16.6.2, but if I'm reading well, the highest available here is 2017, should I upgrade Qt to 5.15?

[jsulm]

@Markyo Visual Studio 2019 C++ compiler is compatible with the one in Visual Studio 2017.
So, you can install Qt for MSVC2017 64bit.

[Markyo]

@jsulm ok thanks for precisions, so I unticked all except MSVC 2017 64-bit

[Markyo]

@jsulm Ok new Qt has been installed, I ran again the command:

C:\Qt\5.12.5\msvc2017_64\bin\qmake.exe -- MYSQL_INCDIR="C:\Program Files\MySQL\MySQL Connector C 6.1\include" MYSQL_LIBDIR="C:\Program Files\MySQL\MySQL Connector C 6.1\lib"

And this time, another one turn to yes, but not MySQL:

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'C:\Qt\5.12.5\msvc2017_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

@Markyo Make sure you start from clean state without any build artefacts from previous tries. In case you're doing out-of-source builds delete and create the build folder. Else checkout the source code again.

@jsulm I deleted the config.cache file, but still get the same result. I don't know how to check if I'm doing out-of-source builds, and what is the build folder.

[jsulm]

@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:

what is the build folder

The folder in which you are when you call cmake.
Out of source build means that the build folder is outside of the source folder.
