Qt MySQL Driver Mingw32-make not working
-
@hobbyProgrammer Workbench I think (I think this one contains the client libs)
-
@jsulm
I already noticed that it went wrong with the spaces, but I was hoping that there was a simple solution for this instead of reinstalling the entire mysql workbench/server.But I'll give it a try as I am desperate to get this connection working

reinstalling the entire mysql workbench/server.
why? Moving the two needed directories to somewhere else should be enough.
-
@Christian-Ehrlicher I can just make a new folder without spaces and move all the files to there?
-
@Christian-Ehrlicher @Christian-Ehrlicher I moved it and used this command (from this tutorial:
cd C:\Qt\5.12.5\Src\qtbase\src\plugins\sqldrivers qmake -- MYSQL_INCDIR=C:\MySQL\include "MYSQL_LIBDIR=C:\MySQL\lib" mingw32-makebut still get the same errors..
-
@hobbyProgrammer Do a clean rebuild
-
@jsulm still results in getting the same error. I should rebuild sqldrivers.pro right?

You're doing in source build which is bad.
Make sure there are no build artefacts. -
@jsulm why is that bad? I'm quite new and just following the instructions from the docs, so I'd like to learn how to do things properly :')

Because you're polluting source tree with build artefacts. If you then want to do a clean rebuild you need to delete all build artefacts and there can be many of them all over the place. Out of source builds are way easier:
- Create a build directory
- Go to that directory
- qmake
- make
- make install
For a clean rebuild delete everything inside build directory (or delete it and create again) and repeat steps 2..5.
By the way: QtCreator does out of source builds by default, so your source tree is clean and it's easier to use version control systems like Git :-)
-
I still did not get it to work.
What I did:
- Moved all the content from MySQL server directory (contained a lot of spaced) to C:/MySQL.
- Used these commands:
cd C:\Qt\5.12.5\Src\qtbase\src\plugins\sqldrivers qmake -- MYSQL_INCDIR=:C\MySQL\include "MYSQL_LIBDIR=C:\MySQL\lib" mingw32-makeyet it still doesn't work. Is there anyone who knows why and can help me? I really want to connect to my MySQL database..
-

MYSQL_INCDIR=:C\MySQL\include
typo?
What was the output of the qmake command?
-
You have the : before the C. Is this just a typo here ?
-
@Christian-Ehrlicher @SGaist
yes that was a typo, but the output stays the same: "Project ERROR: Could not find feature sql-mysql." -
That's not the complete output. Please remove all intermediate files create by qmake (run first 'make distclean', then also remove qmake.cache) and rerun qmake again with the correct mysql parameters. Then show us the output.
-
@Christian-Ehrlicher right now this is my output:
C:\Qt\5.12.5\Src\qtbase\src\plugins\sqldrivers>qmake -- MYSQL_INCDIR=C:\MySQL\include "MYSQL_LIBDIR=C:\MySQL\lib"

MySql .................................. no
So why do you even try to call mingw32-make when the configure step says it could not find the mysql stuff?
There is a config.log (iirc) where you can take a look into why the mysql plugins are not found.MYSQL_INCDIR=C:\MySQL\include "MYSQL_LIBDIR=C:\MySQL\lib"
Why one with " and one without? It's not needed ...
-
@Christian-Ehrlicher It seems like it cannot find the libraries in the global paths.
