Hey, Just in case...
Did you remove "config.cache" before you run qmake again?

hskoglund

@Bonnie Or I was thinking nuke the whole directory :-)

SPlatten

@Bonnie , that looks like its done the trick.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/Users/simonplatten/Qt/5.14.2/clang_64'.

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

Thank you to everyone for your help, at last now the driver has been created and my application is able to connect to the database.

Bonnie

@SPlatten
It is actually in the doc:

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.

I think the doc should make that sentence more sight-catching.
Many people who had their first qmake command unsuccessful would be stucked there, with a never-changing config.log.

@Bonnie , Hello, I'm trying to rebuild the library again and from my notes:

$QTDIRBIN/qmake -- MYSQL_INCDIR="/usr/local/Cellar/mariadb/10.4.13/include/mysql" "MYSQL_LIBDIR=/usr/local/Cellar/mariadb/10.4.13/lib" MYSQL_LIBS="-lmariadb"

This results in:

Usage: /Users/sy/Qt/5.15.1/clang_64/bin/qmake [mode] [options] [files]

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]

I've checked $QTDIRBIN, which contains:

QTDIRBIN=/Users/sy/Qt/5.15.1/clang_64/bin

MariaDB is installed in:

/usr/local/Cellar/mariadb/10.5.7

Can you help?

jsulm

@SPlatten In which directory do you call qmake?

SPlatten

@jsulm, the path of make is specified by the QTDIRBIN environment variable and I've checked the qmake application is in that location.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

That is not what I asked.
In which directory are you when you call qmake?

SPlatten

@jsulm , Ok, thank you, that was part of the problem. I am in:

/Users/sy/Qt/5.15.1/Src/qtbase/src/plugins/sqldrivers

The output now is:

How do I get MySql set to yes ?

I've removed config.cache and re-run qmake, still the same results.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

How do I get MySql set to yes ?

As always in such a situation: check config.log for failed MySQL test and see what exactly the problem was...

SPlatten

@jsulm

> main.cpp:2:10: fatal error: 'sybfront.h' file not found
> #include <sybfront.h>

Not sure why this is an issue, I have built the driver for a previous version.

jsulm

@SPlatten said in Set-up MariaDB library file location programmatically?:

sybfront.h

Google says that header file is part of freetds-dev package (on Ubuntu).

SPlatten

@jsulm , I'll see what I can find.

After some googling:

brew upgrade freetds

Still getting same result tho.

SPlatten

Can anyone offer a solution?

SGaist

Since you want to build the MariaDB backend, what does the checks related to that backend say ?

SPlatten

@SGaist , can you explain what you mean please? This is the content of the config.log:
