Set-up MariaDB library file location programmatically?

SPlatten

@jsulm , if I'm developing it on my own system and no one else is involved or using it, how would this be against any license?

SPlatten

@hskoglund , thank you, I'll look into it. It seems its available for just about every operating system except MAC.

jsulm

@SPlatten I'm not a lawyer and not working for QtCompany (that's why I suggested to ask the company).
You say: you are now developing an app and you want to release it later as closed source. And you want to buy Qt license when you want to release the app. My point was: QtCompany could say that you actually need the commercial license from the beginning as you're developing a closed source application which is going to be distributed. I may be wrong here, but it is worth checking.

If you're not going to distribute your app then there is no issue.

SPlatten

@jsulm , thank you, I'll send Qt an email. Contacting Qt to ask such a question is easier said than done...How do I contact the appropriate person or department in Qt to ask?

https://www.qt.io/contact-qt-services-team

Query sent to Qt.

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

That doesn't contain a mysql folder. I just did:
sudo find / -name sqldrivers/mysql

Nothing was found on my system.

I realize this is probably not your issue here, but I think you ought be aware, at least for future searches, that -name abc/def --- with that / --- will always return false, so you'll never find a match.

On MacOS (I'm Ubuntu) I think you'll find you would have to use -path instead, plus you want a substring match, so you would need e.g.:

sudo find / -path '*sqldrivers/mysql' -print

P.S.
Don't forget the -print which you didn't show you used, else find is remarkably silent ;-)

@jsulm , thank you, just executed that and found:

You do, or at least the QtC want you to, I had the issue when I wanted to open source a project that was previously made under QtLicence, slightly different but that exact topic came up.

It's due to the yearly licensing ~~scam~~ scheme, would be no issue at all if it was a one purchase last for ever kind of deal

I've been trying to follow: https://doc.qt.io/qt-5/sql-driver.html

Lots of issues, for starters a terminal at:/Users/simonplatten/Qt/5.14.2/Src/qtbase/src/plugins/sqldrivers/mysql

Executing qmake: ~/Qt/5.14.2/clang_64/bin/qmake -version

Does not return the same I only get:

QMake version 3.1
Using Qt version 5.14.2 in /Users/simonplatten/Qt/5.14.2/clang_64/lib

I could do with some help on how to turn the source into a driver.

I got a little further:

export QTDIR=/Users/simonplatten/Qt/5.14.2
export QTDIRBIN=$QTDIR/clang_64/bin
cd $QTDIR/Src/qtbase/src/plugins/sqldrivers 
$QTDIRBIN/qmake -- MYSQL_PREFIX=/usr/local

Running configuration tests...

Checking for MySQL... no
Checking for OCI (Oracle)... no

Checking for TDS (Sybase)... no
Done running configuration tests.

  ODBC ................................... no
  PostgreSQL ............................. no
  SQLite2 ................................ no
  SQLite ................................. yes
    Using system provided SQLite ......... no
  TDS (Sybase) ........................... no

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.

I then ran "make", waited for it to complete. Some errors at the end:

Project ERROR: Library 'freetype' is not defined.
make[1]: *** [sub-minimal-make_first] Error 3
make: *** [sub-platforms-make_first] Error 2

Then run "make install".

It would appear this has not built the driver as I still see in the Application Output:

Warning:QSqlDatabase: QMYSQL driver not loaded
Warning:QSqlDatabase: available drivers: QSQLITE QODBC QODBC3 QPSQL QPSQL7
Info: L00000001:onFailure: db, failure: Driver not loaded Driver not loaded

Why does it appear that its all set-up to build sqlite and NOT mysql ?

SPlatten

Can anyone help with this as I still haven't managed to build the Qt MySQL Plugin?

jsulm

@SPlatten There is no point to run "make install" if make failed...
Install libfreetype-dev package and try again.

Also, if you see "Checking for MySQL... no" in configure output, then why even bother calling make?!
To see why MySQL is disabled check the configure.log file.

SPlatten

I'v been through the steps again:

cd $QTDIR/Src/qtbase/src/plugins/sqldrivers 
$QTDIRBIN/qmake -- MYSQL_PREFIX=/usr/local

The output is the same:

Running configuration tests... 
Done running configuration tests.

Again it looks like its set-up to build SQLite and not MySQL. I then run make and the result is:

cd sqlite/ && ( test -e Makefile || /Users/simonplatten/Qt/5.14.2/clang_64/bin/qmake -o Makefile /Users/simonplatten/Qt/5.14.2/Src/qtbase/src/plugins/sqldrivers/sqlite/sqlite.pro ) && /Applications/Xcode.app/Contents/Developer/usr/bin/make -f Makefile 
make[1]: Nothing to be done for `first'.

@jsulm , I tried your instruction:

install: libfreetype-dev: No such file or directory

'config.log' is quite verbose:

Name on your system can be different, simply search for freetype.

I don't mean searching in the filesystem. I mean searching in the package manager.

"The contents of /usr/local/Cellar/mariadb/10.4.6_1/lib:" - this does not answer the question.
Please do:

file /usr/local/Cellar/mariadb/10.4.6_1/lib/libmariadb.3.dylib

And post the output.

Also it can be that MariaDB can't be used with Qt as the error message says that "_mysql_get_client_version" symbol is not defined, but I'm not sure.

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

file /usr/local/Cellar/mariadb/10.4.6_1/lib/libmariadb.3.dylib

/usr/local/Cellar/mariadb/10.4.6_1/lib/libmariadb.3.dylib: Mach-O 64-bit dynamically linked shared library x86_64

I'm sure I've been through this process a few years ago using MariaDB...I just wish I've made some good notes...its a mystery to me MariaDB seems to be exactly the same as MySQL in everyday with the exception of the outside world knowing it as MariaDB, internally the files are still called mySQL, which I'm unsure quite how the author got away with this as Oracle are normally very hot on licensing.

Found this post:

https://forum.qt.io/topic/90065/how-to-create-the-plugin-of-mariadb-for-qt5/19

And have adapted the qmake command to match my system:

qmake -- MYSQL_INCDIR=/usr/local/Cellar/mariadb/10.4.6_1/include/mysql "MYSQL_LIBDIR=/usr/local/Cellar/mariadb/10.4.6_1/lib" MYSQL_LIBS="-llibmariadb"

I'm not sure if libmariadb is correct, the paths are correct.

MYSQL_LIBS="-llibmariadb"

This should be

MYSQL_LIBS="-lmariadb"

@jsulm, Thank you, it still looks like its only set-up for SQLite:

simonplatten@Simons-iMac sqldrivers % $QTDIRBIN/qmake -- MYSQL_INCDIR=/usr/local/Cellar/mariadb/10.4.6_1/include/mysql "MYSQL_LIBDIR=/usr/local/Cellar/mariadb/10.4.6_1/lib" MYSQL_LIBS="-lmariadb"

Running configuration tests...
Done running configuration tests.

Configure summary:

Qt Sql Drivers:
  DB2 (IBM) .............................. no
  InterBase .............................. no
  MySql .................................. no
  OCI (Oracle) ........................... no
  ODBC ................................... no
  PostgreSQL ............................. no
  SQLite2 ................................ no
  SQLite ................................. yes
    Using system provided SQLite ......... no
  TDS (Sybase) ........................... no

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.

@SPlatten Is there configure.log file? If so check it.
