How to compile QMYSQL plugin with MSVC?

[BushyAxis793]

Hello,

I'm trying to recompile the qmysql plugin from MSVC using:

cmake -G Ninja -DCMAKE_PREFIX_PATH="C:\Qt\6.3.0\msvc2019_64" -DMYSQL_INCLUDE_DIR="C:\Program Files\MySQL\MySQL Connector C 6.1\include" -DMYSQL_LIB_DIR="C:\Program Files\MySQL\MySQL Connector C 6.1\lib" C:\Qt\6.3.0\Src\qtbase\src\plugins\sqldrivers\mysql

Unfortunately I get errors that are directly related to the plugin itself.

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Warning (dev) in CMakeLists.txt:
  cmake_minimum_required() should be called prior to this top-level project()
  call.  Please see the cmake-commands(7) manual for usage documentation of
  both commands.
This warning is for project developers.  Use -Wno-dev to suppress it.

How can I solve this problem?

Hi,

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

[BushyAxis793]

@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"

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?

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

Follow the documentation...

[SGaist]

@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.

[BushyAxis793]

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.

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

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.

[BushyAxis793]

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:

[Christian Ehrlicher]

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

[BushyAxis793]

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?

[Christian Ehrlicher]

@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]

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

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

3. I create build-sqldrivers directory

4. I go to build-sqldrivers directory

5. 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

https://justpaste.it/f66k3

[Christian Ehrlicher]

Hostx86/x86/

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

[BushyAxis793]

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:

https://justpaste.it/fvn4x

[Christian Ehrlicher]

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

[BushyAxis793]

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]

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]

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 :]
