@Christian-Ehrlicher that's how it worked with me on postgresql and mysql ; otherwise it'll display an error : mysql model is not defined , and same for postgresql ( speaking about QT 5.11 )

@tmapp Hi, I've tried that but nothing seems to be working. I'm still getting the same error

Not very helpful answer...

Please start with a clean qt source tree, follow the documentation and post the output. Also notice the comments to config.log in the documentation

Hello everyone, I was following through the documentation as suggested by @Christian-Ehrlicher . The first command I added was 'qmake -- MYSQL_INCDIR="C:/Program Files/MySQL/MySQL Connector C 6.1/include" MYSQL_LIBDIR="C:/Program Files/MySQL/MySQL Connector C 6.1/lib"

But the outcome was different to that which was in the documentation. This was what I got:

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
  -project       Put qmake into project file generation mode
                 In this mode qmake interprets [files] as files to
                 be added to the .pro file. By default, all files with
                 known source extensions are added.
                 Note: The created .pro file probably will
                 need to be edited. For example add the QT variable to
                 specify what modules are required.
  -makefile      Put qmake into makefile generation mode (default)
                 In this mode qmake interprets files as project files to
                 be processed, if skipped qmake will try to find a project
                 file in your current working directory

Warnings Options:
  -Wnone         Turn off all warnings; specific ones may be re-enabled by
                 later -W options
  -Wall          Turn on all warnings
  -Wparser       Turn on parser warnings
  -Wlogic        Turn on logic warnings (on by default)
  -Wdeprecated   Turn on deprecation warnings (on by default)

Options:
   * You can place any variable assignment in options and it will be *
   * processed as if it was in [files]. These assignments will be    *
   * processed before [files] by default.                            *
  -o file        Write output to file
  -d             Increase debug level
  -t templ       Overrides TEMPLATE as templ
  -tp prefix     Overrides TEMPLATE so that prefix is prefixed into the value
  -help          This help
  -v             Version information
  -early         All subsequent variable assignments will be
                 parsed right before default_pre.prf
  -before        All subsequent variable assignments will be
                 parsed right before [files] (the default)
  -after         All subsequent variable assignments will be
                 parsed after [files]
  -late          All subsequent variable assignments will be
                 parsed right after default_post.prf
  -norecursive   Don't do a recursive search
  -recursive     Do a recursive search
  -set <prop> <value> Set persistent property
  -unset <prop>  Unset persistent property
  -query <prop>  Query persistent property. Show all if <prop> is empty.
  -qtconf file   Use file instead of looking for qt.conf
  -cache file    Use file as cache           [makefile mode only]
  -spec spec     Use spec as QMAKESPEC       [makefile mode only]
  -nocache       Don't use a cache file      [makefile mode only]
  -nodepend      Don't generate dependencies [makefile mode only]
  -nomoc         Don't generate moc targets  [makefile mode only]
  -nopwd         Don't look for files in pwd [project mode only]

Any ideas?
Thanks

Hi,

You are likely not in the right folder, likely in your Qt installation rather than sources.

Alfie Anil

So I opened the terminal from the qt5.13.2 mingw32. Is that where i open the terminal from or is it another directory?

Christian Ehrlicher

That's correct. But then you have to go to the correct source dir as you can see in the documentation: <srcdir>\qtbase\src\plugins\sqldrivers
Is it really that hard to follow the instructions?

Alfie Anil

I've tried everything said but still comes up with the exact error.

Did you really call the correct qmake in the correct directory? I would guess no.

Alfie Anil

@Christian-Ehrlicher Yes I did. As stated in the documentation I cd to the correct directory and then followed the commands as given.

@Alfie-Anil The question was rather: did you call correct qmake?
To make sure you call correct qmake use absolute path (instead of simply calling qmake).

Alfie Anil

So do you mean 'C:<NecessaryDirectory>? Yes

jsulm

@Alfie-Anil Yes, absolute path like c:\Qt\5.12.0\mingw73_64\bin\qmake.exe

Alfie Anil

Yes That's what I did

Alfie Anil

@jsulm Actually I did get it working. But then I ran into the problem that although the problem was gone, none of the sql commands would not work so I was trying to fix that. Then, I ran into a problem with the computer which meant I had to reset the computer. So now I have to do it all over again (hahaha). (I've tried all the steps I did before)
