How to compile QMYSQL plugin with MSVC?

SGaist · 25 Mar 2025, 17:54

Hi,

I would recommend following the instructions shown in Qt's documentation.

@SGaist Thanks for reply!

I followed the tutorial from the website:

mkdir build-sqldrivers
cd build-sqldrivers
qt-cmake -G Ninja <qt_installation_path>\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=<qt_installation_path>\<platform> -DMySQL_ROOT="C:\mysql-8.0.22-winx64"
cmake --build .
cmake --install .

In my case, instead of qt-cmake I used cmake:

mkdir build-sqldrivers
cd build-sqldrivers
cmake -G Ninja C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=C:\Qt\Tools\CMake_64\bin -DMySQL_ROOT="C:\mysql-8.0.28-winx64\mysql-8.0.28-winx64"
cmake --build .
cmake --install .

My CMD looks like this:

C:\mysql-8.0.28-winx64\build-sqldrivers>cmake -G Ninja C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=C:\Qt\Tools\CMake_64\bin -DMySQL_ROOT="C:\mysql-8.0.28-winx64\mysql-8.0.28-winx64"

-- Configuring done (1.0s)

-- Build files have been written to: C:/Qt/6.3.0/Src/qtbase/src/plugins/sqldrivers

C:\mysql-8.0.28-winx64\build-sqldrivers>cmake --build .
Error: could not load cache

C:\mysql-8.0.28-winx64\build-sqldrivers>

The build-sqldrivers folder is empty. What could be wrong?
Have a good day

@BushyAxis793 qt-cmake is not a typo in the doc, it is a wrapper that executes cmake configured for the Qt build you are about to use.

Indeed my mistake. I made corrections. But I still have a problem:

C:\Users\mnawr>cd C:\mysql-8.0.28-winx64\build-sqldrivers

C:\mysql-8.0.28-winx64\build-sqldrivers>qt-cmake -G Ninja C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=C:\Qt\Tools\CMake_64\bin -DMySQL_ROOT="C:\mysql-8.0.28-winx64\mysql-8.0.28-winx64"

-- Configuring done (1.0s)
-- Generating done (0.3s)
-- Build files have been written to: C:/Qt/6.3.0/Src/qtbase/src/plugins/sqldrivers

C:\mysql-8.0.28-winx64\build-sqldrivers>

As you can see I use qt-cmake instead of cmake. But build-sqldrivers folder is still empty.

Build files have been written to: C:/Qt/6.3.0/Src/qtbase/src/plugins/sqldrivers

As you can see they are generated there.
Please start over with a clean source directory.

I removed everything and start again with create build-sqldrivers and the directory C:/Qt/6.3.0/Src/qtbase/src/plugins/sqldrivers looks like:

So I went to the directory with command: cd C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers

and wrote cmake --build . And this is the result:

You did not open the correct visual studio command prompt so the vc env variables are not properly set up.

BushyAxis793 · 27 Mar 2025, 19:53

OK. So I used Visual Studio Developer Command Prompt and got different errors. I tried also PowerShell but no result. Should I install any special version for MSVC?

@BushyAxis793 said in How to compile QMYSQL plugin with MSVC?:

Should I install any special version for MSVC?

Why?
Start with a clean build dir from a properly set up environment and if you encounter errors, post them here.

BushyAxis793 · wrote on 28 Mar 2025, 17:41

OK. I understand. Let me show you step by step what I do:

Clear everything
Open Visual Studio Developer Command Prompt
I go to C:\mysql-8.0.28-winx64\

I create build-sqldrivers directory

I go to build-sqldrivers directory

I input command:
qt-cmake -G Ninja C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=C:\Qt\Tools\CMake_64\bin -DMySQL_ROOT="C:\mysql-8.0.28-winx64\mysql-8.0.28-winx64"

And I got error

Hostx86/x86/

You opened the wrong visual studio command prompt. Qt is built with 64bits...

BushyAxis793 · wrote on 28 Mar 2025, 18:50

OK. So I run again Visual Studio Command Prompt and check configuration with:

C:\Users\mnawr\source\repos\Project2>echo %VSCMD_ARG_TGT_ARCH%
x86

Then I change to x64 with:

set VSCMD_ARG_TGT_ARCH=x64

And check again:

C:\Users\mnawr\source\repos\Project2>echo %VSCMD_ARG_TGT_ARCH%
x64

And again create build-sqldrivers directory, run qt-cmake.. and got the error again:

Please open the correct visual studio command prompt for 64 bits... is it really that hard?

BushyAxis793 · wrote on 28 Mar 2025, 19:35

OK. I used x64 Native Tools Command Prompt for VS 2022 and my result is:

C:\mysql-8.0.28-winx64\build-sqldrivers>

I can't see any error but when I go to C:\mysql-8.0.28-winx64\build-sqldrivers\plugins\sqldrivers

I expected qsqlmysql.dll instead of qsqlmysqld.dll.

Christian Ehrlicher · wrote on 28 Mar 2025, 19:57

You have to build debug and release libs (msvc is picky here)

-DCMAKE_BUILD_TYPE=Release

-DCMAKE_BUILD_TYPE=Debug

Debug was already built.

BushyAxis793 · wrote on 29 Mar 2025, 10:33

Thanks for reply. I run:
qt-cmake with -DCMAKE_BUILD_TYPE=Release parameter. Now my C:\mysql-8.0.28-winx64\build-sqldrivers\plugins\sqldrivers directory looks much better:

I can see qsqlmysql.dll.

I added to my project. It works perfect!

Thank you very much for help and for you patience!

Have a good day :]
