The .dylib was placed automatically with the other drivers. But still Qt can not find the driver

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC QPSQL QMIMER

What am I doing wrong?

@DeadSo0ul As always in such situations and recommended here every day - start your app on the command line with QT_DEBUG_PLUGINS=1 env var set.

Hi @Christian-Ehrlicher
I ran Qt Creator using

export QT_PLUGIN_PATH=/Users/boyankiovtorov/Qt/6.7.0/macos/plugins/sqldrivers

export QT_DEBUG_PLUGINS=1

and

open "QT Creator.app"

I did get an output of

@DeadSo0ul said in Mysql drivers built but qt can not find them:

qt.core.plugin.factoryloader: "Failed to extract plugin meta data from '/Users/boyankiovtorov/Qt/6.7.0/macos/plugins/sqldrivers/libqsqlmysql.dylib': '/Users/boyankiovtorov/Qt/6.7.0/macos/plugins/sqldrivers/libqsqlmysql.dylib' is not a valid Mach-O binary (wrong architecture)"

Isn't this obvious enough?

DeadSo0ul

@Christian-Ehrlicher It is, but the problem is that when I firstly tried to build for my architecture I got the error

ld: warning: ignoring file '/usr/local/mysql-8.3.0-macos14-arm64/lib/libmysqlclient.23.dylib': found architecture 'arm64', required architecture 'x86_64'

and from there my build crashed for arm64

Here is the command I used if it helps somehow

./qt-cmake /Users/boyankiovtorov/Qt/6.7.0/Src/qtbase/src/plugins/sqldrivers -GNinja -DMySQL_INCLUDE_DIR=/usr/local/mysql-8.3.0-macos14-arm64/include -DMySQL_LIBRARY=/usr/local/mysql-8.3.0-macos14-arm64/lib/libmysqlclient.dylib

SGaist

@DeadSo0ul hi,

Do you have an Intel or an M series machine ?

You need to either have MySQL for x86_64 or build Qt for arm64.

hskoglund

Hi @SGaist don't worry about Qt's architectures, I think at least from 6.2 the online version installs both of them, e.g.

file ~/Qt/6.7.0/macos/lib/QtCore.framework/QtCore
/Users/henry/Qt/6.7.0/macos/lib/QtCore.framework/QtCore: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
/Users/henry/Qt/6.7.0/macos/lib/QtCore.framework/QtCore (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
/Users/henry/Qt/6.7.0/macos/lib/QtCore.framework/QtCore (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

However homebrew (where you usually get the MySql stuff) only gives you one architecture, so you have to check with file

DeadSo0ul

@SGaist Hi
I am on a M series machine. Does that build have to be done manually or is it done during installation of Qt. I can not have MySQL for x86-x64 as it won't link the driver

DeadSo0ul

@hskoglund Hi,
I installed mysql from its official site.
I checked the architecture

/Users/boyankiovtorov/Qt/6.7.0/macos/lib/QtCore.framework/QtCore: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
/Users/boyankiovtorov/Qt/6.7.0/macos/lib/QtCore.framework/QtCore (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
/Users/boyankiovtorov/Qt/6.7.0/macos/lib/QtCore.framework/QtCore (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

Should I install through homebrew?

Hi, just try your qt-cmake command again, but this put this at the end:

-DCMAKE_OSX_ARCHITECTURES="arm64"

@hskoglund if it's a custom build, I want to worry about it :-)

@DeadSo0ul the long variant would be to get a multi-arch MySQL or get it for each architecture and use lipo to put them together.

@hskoglund
I still get the same result

ld: warning: ignoring file '/usr/local/mysql-8.3.0-macos14-arm64/lib/libmysqlclient.23.dylib': found architecture 'arm64', required architecture 'x86_64'

hskoglund

You need to nuke (delete) the previous build/directory
or do a new download and then try qt-cmake again (with -DCMAKE_OSX_ARCHITECTURES="arm64" added at the end)

DeadSo0ul

@hskoglund If I do understand you correctly I had done it before running the command as the files built were easy to track Screenshot 2024-04-16 at 22.57.57.png

Ignore the directory where I build as I overkill the whole process for no reason

I did try to build in another directory but without success

hskoglund

No I mean delete all of the /Users/boyankiovtorov/Qt/6.7.0/Src/qtbase/src/plugins/sqldrivers directory
If you don't have a copy easiest is just to download the 6.7.0 source again.

hskoglund

Here's how I built MySQL (some time ago :-) using Homebrew
Download Qt sources in ~/Downloads then do these commands:

brew install mysql
cd ~/Downloads/qt-everywhere-src-6.7.0/qtbase/src/plugins/sqldrivers
~/Qt/6.7.0/macos/bin/qt-cmake -DMySQL_LIBRARY=/usr/local/opt/mysql/lib/libmysqlclient.dylib -DMySQL_INCLUDE_DIR=/usr/local/opt/mysql/include/mysql  -DCMAKE_OSX_ARCHITECTURES="arm64" .
make

@hskoglund
It was the same way I built the driver for 6.2 but still not working

cd ~/Downloads/qt-everywhere-src-6.7.0/qtbase/src/plugins/sqldrivers
boyankiovtorov@Boyans-MacBook-Air sqldrivers % ~/Qt/6.7.0/macos/bin/qt-cmake -DMySQL_LIBRARY=/opt/homebrew/opt/mysql/lib/libmysqlclient.dylib -DMySQL_INCLUDE_DIR=/opt/homebrew/opt/mysql/include/mysql  -DCMAKE_OSX_ARCHITECTURES="arm64" .

it gives a warning that ninja is recommended

but the error is still the same

[ 41%] Linking CXX shared module ../plugins/sqldrivers/libqsqlmysql.dylib

hskoglund

If you check the MySql dll with file, e.g.:

file /opt/homebrew/opt/mysql/lib/libmysqlclient.dylib

If it says "x86_64" then you need to download/install a dylib/dll with the same name but has the architecture "arm64"

DeadSo0ul

@hskoglund It is arm64

/opt/homebrew/opt/mysql/lib/libmysqlclient.dylib: Mach-O 64-bit dynamically linked shared library arm64

hskoglund

Hi, indeed I just tried it myself and something's changed with 6.7.0, that switch -DCMAKE_OSX_ARCHITECTURES="arm64" does not seem to work anymore :-(
I remember that was a bug before and that you had to edit some cmake text file, i'll check...
