After build and install MySql driver for Qt it's unable to load the MySql Drive
-
@Malibob In the screen shot you did not build and install anything. You only called qmake. Did you also call make/make install?
-
@Malibob You can use https://www.dependencywalker.com/ to check whether something is missing for the MySQL plug-in DLL.

Your mysql driver has to be accessed by the compiler you are using. Put it in the bin directory of mingw

I would download mysql connector 6.1(last one with prebuilt libmysql.dll and use it to be sure you did not mess up the build.
If that does not work open creator, click projects on left side, switch top to debug and add a Build Environment entry called QT_DEBUG_PLUGINS and set it to 1. Then run in debug mode and read through the module load trace to see where it is loading what module from and whether it is able to load what it is looking for.

I'm using 64bit windows, Qt creator version 32-bit, mingw81_64 and MySql 64 bit. What are the .dll s that i want to use and where? I'm confused with this .dll stuff -
@Malibob Open qsqlmysql.dll in DependencyWalker and see whether something is missing (especially the MySQL client lib).
-
@Malibob There is - in your Qt installation: on my machine it is in c:\Qt\5.11.1\mingw53_32\plugins\sqldrivers
-
@Malibob From that screen-shot I can't say. Please collapse all MS DLLs. Especially check whether the MySQL client lib is found.
