QMYSQL driver not loaded and Library mysql is not defined
-
@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?
@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. -

@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.@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. -

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

@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.
@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. -

@jsulm I'm building in this folder:
C:\Qt\5.12.5\Src\qtbase\src\plugins\sqldriversI'm not sure I have to delete this folder
-
@Markyo Well, since you're not doing out of source build you should not delete it. Instead delete all build artefacts (files created during your build attempts) manually.

@Mickleholts hi,
@jsulm already fave quite a lot of advices. Did you follow them ?

Hello, I'm coming back here again to look for some solutions !
Due to difference of version, I reinstalled another version, several times, and for my last try, with this command:C:\Qt\5.12.5\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"I get this environment problem:
Project ERROR: Cannot run compiler 'cl'. Output: =================== =================== Maybe you forgot to setup the environment?Honestly, I don't understand why it is so hard to use the MySQL driver..
-
@Markyo said in QMYSQL driver not loaded and Library mysql is not defined:
Maybe you forgot to setup the environment?
You did not set up the MSVC environment as the error tells you - you have to run it from a MSVC command prompt. Nothing Qt specific - if you want to use a compiler in an environment you have to properly set it up.
Honestly, I don't understand why it is so hard to use the MySQL driver..
Ask Oracle why they changed their license so it can be shipped as pre-build library

Just run 'nmake'. Once everything is built, you must run 'nmake install'. Qt will be installed into 'C:\Qt\5.12.5\msvc2017'. Prior to reconfiguration, make sure you remove any leftovers from the previous build.So, MySQL is available, I typed nmake, then nmake install, then nmake install in mysql directory, everything seems to work.
I rebuilt my app, and ran the app and get this:
QML debugging is enabled. Only use this in a safe environment. QSqlDatabase: QMYSQL driver not loaded QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7Don't understand why it is available but not loaded.

The driver needs the dlls to be loaded.
You can help finding them modifying the PATH environment variable in the Run part of the Project panel in Qt Creator.
