Added QMysql plugin to Qt Creator project on MacOS Ventura 13.4

[BushyAxis793]

@hskoglund Thanks for reply. I was follow your tip and the architecture is:

mikolajnawrocki@MacBook-Pro-Mikoaj ~ % lipo -info /Users/mikolajnawrocki/Desktop/build-sqldrivers/plugins/sqldrivers/libqsqlmysql.dylib
Non-fat file: /Users/mikolajnawrocki/Desktop/build-sqldrivers/plugins/sqldrivers/libqsqlmysql.dylib is architecture: x86_64

[hskoglund]

Hi, if you're running QT an M1 MacBook Pro then the architecture should be "arm64".

[BushyAxis793]

@hskoglund I know but my architecture is x86_64/arm64 so I need universal plugin. No idea how to install arm only version of QT.

[hskoglund]

Building wrih universal architecture is a good idea if you plan to distribute the .dylib to other Mac computers, but Oracle only allows a build for a single compurer anyway:

[BushyAxis793]

@hskoglund OK. So, can You tell me what is in you opinion best way to add qmysql plugin to qt creator?

[hskoglund]

If you do that qt-cmake command again with the architecture specified (same as I posted 7 hours ago):

/Users/mikolajnawrocki/Qt/6.5.0/macos/bin/qt-cmake ... -DCMAKE_OSX_ARCHITECTURES="arm64"

and then try the lipo command:

lipo -info /Users/mikolajnawrocki/Desktop/build-sqldrivers/plugins/sqldrivers/libqsqlmysql.dylib

if it still says "x86_64" then try nuking the build directory :-)

[BushyAxis793]

@hskoglund Same result :(

I have no idea why I still got x86_64 architecture...

All I want is just add QMySQL plugin to my Qt Creator project nothing more.

[hskoglund]

The stackoverflow post you linked to 9 days ago, I looked at it now and it is a very good instruction how to build the MySQL plugin.
Pleas try it again and remember to erase all build directories and download a fresh copy of Qt”s sources every time you complie/build the plugin.

@hskoglund I did it but when I input

cmake --build .

I got:

What now?

[hskoglund]

You got to step 7 ok in that post https://stackoverflow.com/questions/73908494/qmysql-driver-not-loaded-on-mac-os-for-mac-m1-m2-users/73908495 but in step 8 you forgot to type:
-DCMAKE_OSX_ARCHITECTURES="arm64"

Remember to erase the build folders and download a fresh copy of Qt's sources before building again :-)

[BushyAxis793]

@hskoglund Ok so I remove and Install again Sources and delete build_sqldriverrs folder to.

1. I installed ninja with homebrew

2. I go to

cd /Users/mikolajnawrocki/Qt/6.5.0/Src

3. I Input

./configure -sql-mysql -- -DCMAKE_INCLUDE_PATH="/usr/local/mysql/include" -DCMAKE_LIBRARY_PATH="/usr/local/mysql/lib"

4. Then I go to

 cd /Users/mikolajnawrocki/Qt/6.5.0/macos/plugins/sqldrivers

and Input

mikolajnawrocki@MacBook-Pro-Mikoaj sqldrivers % mkdir build_sqldrivers
mikolajnawrocki@MacBook-Pro-Mikoaj sqldrivers % cd build_sqldrivers

5. Next I Input

/Users/mikolajnawrocki/Qt/6.5.0/macos/bin/qt-cmake -G Ninja  /Users/mikolajnawrocki/Qt/6.5.0/Src/qtbase/src/plugins/sqldrivers -DCMAKE_INSTALL_PREFIX=/Users/mikolajnawrocki/Qt/6.5.0/macos -DMySQL_INCLUDE_DIR="/usr/local/mysql/include" -DMySQL_LIBRARY="/usr/local/mysql/lib/libmysqlclient.dylib" -DCMAKE_OSX_ARCHITECTURES="arm64"

6. Then I input

sed -i -e 's/-arch x86_64/-arch arm64/g' /Users/mikolajnawrocki/Qt/6.5.0/macos/plugins/sqldrivers/build_sqldrivers/build.ninja

7. Next I input

cmake --build .

8. Then I input

cmake --install .

at the end I copy libqsqlmysql.dylib from build_sqldrivers to sqldrivers.

Everything seems be ok. But when I open my project I got below errors

The crash occurs 50 seconds after you started your app so I'm guessing it is unrelated to loading the MySQL plugin.

So that means you've managed to build the MySQL pliugin, nice!

@hskoglund It seems I got QMySQL plugin added to Qt Creator!

Thanks a lot everyone! @Christian-Ehrlicher @hskoglund @SGaist

However now I have new problem. But I think I should create new topic for this. Anyway thank you very much and have a great day!
