QT5.15.0, MySQL database, msvc2015_64 and Windows 10

[SGaist]

Hi and welcome to devnet,

What instructions are you following ?

[Bonnie]

1. Open "VS2015 x64 Native Tools Command Prompt" from your vs2015 start menu folder
2. C:\Qt\5.15.0\msvc2015_64\bin\qtenv2.bat
3. cd path\to\qt-everywhere-src-5.15.0\qtbase\src\plugins\sqldrivers

Then follow this instruction:
https://doc.qt.io/qt-5/sql-driver.html#how-to-build-the-qmysql-plugin-on-windows

And...don't use ``` as line break, it is the code tag of this forum...

Unfortunately, I tried to follow lots of instructions found on the net during the last days, but no one worked for me.

Thank you for your advice and support!

So, I did in this way:

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'C:\Qt\5.15.0\msvc2015_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

It seems a problem with 32 and 64-bit architecture.
I'm using msvc2015_64 but I realized that vs2015 x86 native tools is placed in the 32bit folder Program Files (x86).
On this forum, I found a topic with the same problem, and it was suggested to run vcvarsall.bat amd64, I did it, too, but nothing changed, the problem is still there.

Should I revert to 32bit?

[Bonnie]

@Marcus-Barnet
No need. I asked you to open the x64 Native Tools, not x86.
It doesn't matter that it is placed in the (x86) folder because visual studio will always be installed there.
And you should not run nmake yet because the MySql configure status of qmake is still no according to the output your posted.

Checking for MySQL... no
...
  MySql .................................. no

You need to fix that first.

Now that your first try has failed, there is an important note in the instruction you need to notice:

If something goes wrong and you want qmake to recheck your available drivers, you must remove config.cache in <QTDIR>/qtbase/src/plugins/sqldrivers - otherwise qmake will not search for the available drivers again. If you encounter an error during the qmake stage, open config.log to see what went wrong.

So every time you try to run qmake again, remember to delete config.cache first.
Now, be sure that you start from the x64 Native Tools Command Prompt, delete config.cache and run that qmake command again.
If the Mysql status is still no, post the output and config.log here.
If it is yes, don't run nmake, but run nmake sub-mysql as in the instruction because you don't need to compile other plugins like odbc.

[Marcus Barnet]

@Bonnie Thank you for your support!

I deleted the config.cache and I run again the x64 native tools.

Prior to reconfiguration, make sure you remove any leftovers from

I still get "no" for mysql, so this is the cocntent of the config.log

I don't know if this information is useful, but I'm using XAMPP for the MySQL database and it works fine since I'm able to create db by using phpmyadmin.

[Bonnie]

@Marcus-Barnet
I'm not familiar with XAMPP but seems it downloads MySQL Connector C 6.1 , I think that should be fine.
The configure part we are looking for should be "source 6 (type inline) of library mysql", so

It seems that it can't find windows sdk (which includes rc.exe). Have you installed that?

[hskoglund]

Just to add to @Bonnie, how to get rc.exe working: you can try running the VS2015 Update 3 setup again and this time add:
Windows and Web Development -> Universal Windows App Development Tools -> Tools (1.4.1) and Windows 10 SDK

[Marcus Barnet]

I've installaed Windows 10 SDK (10.0.19041.0), but I still get the rc.exe error.

EDIT: I had the same problem with QtCreator and I solved it by adding C:\Program Files (x86)\Windows Kits\8.1\bin\x64; to PATH variable.

[hskoglund]

Windows 10 SDK (10.0.19041.0) is too modern for MSVC2015 I think :-(

Either upgrade your MSVC2015 to MSVC2017 or MSVC2019
or downgrade your Windows 10 SDK to 10.0.17763.0 link here

[Marcus Barnet]

I have this folder C:\Qt\5.15.0\msvc2019_64 and I have Visual Studio 2017 installed on my Windows.

Do I just need to switch to msvc2019 to solve the problem?
If so, should I download and install VS2019?

[hskoglund]

Yes, using MSVC2019 will help with the mysql stuff.
When you install it, select ”native Win32 development in C/C++” so you get the Win 10 SDK installed as well.

[Bonnie]

@Marcus-Barnet said in QT5.15.0, MySQL database, msvc2015_64 and Windows 10:

Hmmm...Then I think maybe it can work.
Usually start from native tools command prompt would add the win sdk bin to PATH, but yours seems having some problems.
After open from the native tools, run "path" to output your PATH and see if there is win sdk bin in it or anything conflicting.

May be I'm on the right road, I run x64 VS2019 Native tools and now it finds the MySQL!

But I get an error when I launch nmake install:

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'C:\Qt\5.15.0\msvc2019_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

P.S. do I need to run vcvarsall.bat after qtenv2.bat?

[Bonnie]

P.S. do I need to run vcvarsall.bat after qtenv2.bat?

No, Native tools command prompt have called vcvarsall.bat so you don't need to run it again.

C:\Program Files (x86)\Windows Kits\10\bin\x64;C:\Program Files (x86)\Windows Kits\10\bin\x86;

This seems not right.
There should not be x64 and x86 bin in the PATH at the same time.
And your PATH value seems quite messed up...I'm not sure where do they come from...
What is the path output from a normal command prompt?
You may need to do some cleanup and delete some values...

@Marcus-Barnet
Ok, there is not x86 and x64 bin in the normal PATH, I'm a little confused...
But I've checked your vs2019 output.
It seems the mysql plugins have already been copied to the plugin folder.
So you should have done the job.
Check C:\Qt\5.15.0\msvc2019_64\plugins\sqldrivers, do you have qsqlmysql.dll and qsqlmysqld.dll there?
If yes, just copy libmysql.dll from "MySQL Connector C 6.1\lib" (or bin, I'm not sure) to "C:\Qt\5.15.0\msvc2019_64\bin", then it is finished.

Ah, if you still want to try the vs2015_64 one.
I think maybe you could run "set PATH=C:\Program Files (x86)\Windows Kits\8.1\bin\x64;%PATH%" after qtenv2.bat.

[Marcus Barnet]

Finally, it works! Thank you!
I just followed your advice and I copied the libmysql.dll to "C:\Qt\5.15.0\msvc2019_64\bin" after checked the presence of qsqlmysql.dll and qsqlmysqld.dll in sqldrivers.

I tried to compile my project in QtCreator and it worked with mscv2019_64 so I think it's OK for me to use this one instead of the 2015 version.

The project compiles and it is able to connect to MySQL, I only get a warning from the Qtcreator console:

:-1: warning: "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe" is used by qmake, but "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\cl.exe" is configured in the kit.
Please update your kit (Desktop Qt 5.15.0 MSVC2019 64bit) or choose a mkspec for qmake that matches your target environment better.

[Bonnie]

@Marcus-Barnet
That's a little weird, that path seems to be vs2015 compiler.
Check the Kits setting of QtCreator, make sure you select the right C/C++ compiler.
For vs2019_64 that should be 16.x.xxxxx.xx (amd64)
