"Cannot find file: mysql.pro" while building MySQL driver in Qt

SGaist

https://en.wikipedia.org/wiki/8.3_filename

It should be good to build the plugin.

CrowSun

@SGaist so that solution is valid? to replace files in folder.
Or I should avoid it and try an 8.3 notation?

SGaist

Replace ? I thought you wanted to copy the headers and libraries in their own folder without spaces. That or the notation should both work.

CrowSun

@SGaist I made a try with copying only now and in the end of that huge text block I receive an error.

SGaist

Are you sure that your MySQL library is built for MinGW ?

CrowSun

@SGaist i'm so ashamed of my non-acquaintance, but no, I'm not sure.
I have installed it with a "mysql-installer-community-5.7.21.0.msi" which I downloaded from official site.
How I can figure out that my MySQL library is for MinGW?

SGaist

You can use Dependency Walker to see if it depends on the Visual Studio runtime.

SGaist

One other thing to check is whether your library is 32 or 64 bit.

CrowSun

@SGaist I suggest, that I need a 32bit library for mingw?

CrowSun

@SGaist I uninstalled mySql from my pc and than I downloaded MySql community Server for windows 32bit (btw I have a 64bit windows). Than I unpacked zip archive in a folder without spaces and entered all previous commands in console. And FINALLY it all executed without errors.
Thanks to everyone who replied on my topic and thank you SGaist for all answers and patience!

@CrowSun
Could you give me a details for build mysql for android on windows ?
I am using window10 x64 qt5.10.1(vs2015) mysql-connector-c-6.1.11-winx64.zip
Could make a one step by step instruction ?
Best regards,
jeff

@SGaist Sir, this link is not working anymore with the error code 404.

SGaist

@Saad02 which link are you referring to ?

Saad02

@SGaist This one-
http://download.qt.io/official_releases/qt/5.7/5.7.1/single/qt-everywhere-opensource-src-5.7.1.zip
It's in the here quote above.

Actually I have mysql folder but there is CMakeLists instead of qt project file (.pro)
I tried with cmake too. And here is the result-
https://forum.qt.io/topic/146382/how-to-create-qt-6-5-mysql-driver-with-cmake?_=1688809685576

SGaist

@Saad02 there was an issue with the archive at some points and this version of Qt is available in a different subfolder.

You seem to be following Qt 6 instructions to build for Qt 5. It won't work as Qt 6 is using cmake and Qt 5 is using qmake.
