Hi, I'm trying to build a MariaDB driver, reading doc (https://doc.qt.io/qt-5/sql-driver.html#qmysql) and another info on internet, but I've this problem:
C:\>cd C:\Users\Ste\Programmi\Qt\5.15.0\Src\qtbase\src\plugins\sqldrivers C:\Users\Ste\Programmi\Qt\5.15.0\Src\qtbase\src\plugins\sqldrivers>C:\Users\Stefano\Programmi\Qt\5.15.0\mingw81_64\bin\qmake -- "MYSQL_INCDIR=C:\Program Files\MariaDB\MariaDB Connector C 64-bit\include" "MYSQL_LIBDIR=C:\Program Files\MariaDB\MariaDB Connector C 64-bit\lib" -llibmariadb" Project ERROR: Cannot run compiler 'g++'. Output: =================== =================== Maybe you forgot to setup the environment?I tried to add on path "C:\Users\Ste\Programmi\Qt\5.15.0\mingw81_64\bin" but the result is the same.
Can you help me?Thanks.

Hi
Try run the
"C:\Qt\5.15.0\mingw81_64\bin\qtenv2.bat"
before qmake
-
Hi and thanks for answer.
With qtenv2.bat the situation has improved.
The parameter "-libmariadb" gave an errore and I had to delete it.
Moreover the procedure asked me to compile with mingw32 and not 64. Is normal?I would like to ask if you can tell me wich is the advantage to use Qt driver instead ODBC (sure more simple and rapid to configure).
Thanks.
P.S. The PC is still compiling the driver, I hope everything goes well until the end.

From a programming perspective, there will be no different but it could be faster than ODBC, and might offer integration/features not available via ODBC but its not certain.
Sorry about the compile error. I have never set it complains about
EGL/egl.h: bulding the sql plugins. really strange. I have no idea why.

@Christian-Ehrlicher
But in the first post it clearly looks like he is only building plugin ?
-
@mrjj but not on the second - at least make / mingw32-make was run in the wrong directory
-
Hi, I'm returned :D
I'm still trying to make mariadb driver, but I've a problem (as usual :( )
This are my steps:- I moved to directory: \Qt\5.15.0\Src\qtbase\src\plugins\sqldrivers
- I run command: \Qt\5.15.0\mingw81_64\bin\qmake -- MYSQL_INCDIR="C:/Program Files/MariaDB 10.5/include" MYSQL_LIBDIR="C:/Program Files/MariaDB 10.5/lib"
but I've this result:
Running configuration tests... Done running configuration tests. Configure summary: Qt Sql Drivers: DB2 (IBM) .............................. no InterBase .............................. no MySql .................................. no OCI (Oracle) ........................... no ODBC ................................... yes PostgreSQL ............................. no SQLite2 ................................ no SQLite ................................. yes Using system provided SQLite ......... no TDS (Sybase) ........................... no Qt is now configured for building. Just run 'mingw32-make'. Once everything is built, you must run 'mingw32-make install'. Qt will be installed into '\Qt\5.15.0\mingw81_64'. Prior to reconfiguration, make sure you remove any leftovers from the previous build.Why MySql is = no?
What am I missing, and why tell to run mingw32-make and not 64?
Thanks for help.

As stated in the docs - take a look in the config.log and see why it does not find mysql libs in the directories you passed to qmake
-
Hi Christian and thanks for your help.
To be honest, I don't find the documentation very clear.
Probably because I don't very well English.This is Config.log:

But when SGaist ask to compile into mysql folder, I've a different error:
Project ERROR: Library 'mysql' is not defined.

Hi @Stefanoxjx, I'm seeing several different paths in your posts:
- C:\Program Files\MariaDB\MariaDB Connector C 64-bit\include
- C:\Program Files\MariaDB 10.5\include
- C:\Utils\my_sql\mysql-5.7.25-winx64\include
Please double-check where you've installed MySQL or MariaDB. Where is
mysql.h? Where islibmysql.liborlibmariadb.lib?
-
Hi, you see different paths because initially I had MariaDB connector installed too.
Now MariaDB connector is unistalled.
Answering your questions:
MariaDB is installed to: C:\Program Files\MariaDB 10.5
mysql.h is to: C:\Program Files\MariaDB 10.5\include\mysql
libmariadb.lib is to: C:\Program Files\MariaDB 10.5\libNow, I recheck paths and execute these steps:
set path=%path%;C:\Program Files\MariaDB 10.5\lib;C:\Program Files\MariaDB 10.5\include;C:\Program Files\MariaDB 10.5\include\mysql;D:\Programmi\Qt\5.15.0\mingw81_64\bin cd D:\Programmi\Qt\5.15.0\Src\qtbase\src\plugins\sqldrivers\mysql qmake -- MYSQL_INCDIR="C:/Program Files/MariaDB 10.5/include/;C:/Program Files/MariaDB 10.5/include/Mysql" MYSQL_LIBDIR="C:/Program Files/MariaDB 10.5/lib" MYSQL_LIBS="-llibmariadb"and result is the same: MYSQL = NO
-
@Stefanoxjx said in MariaDB plugin:
and result is the same: MYSQL = NO
And again you did not look into the config.log to see where the error is... I'm giving up.

No Christian, I'm watched config.log, but is the same already posted:

Well, your mysql.h is not found in C:\Program Files\MariaDB 10.5\include so that's why it failed here.

No Christian, I'm watched config.log, but is the same already posted:
If you pass different command line arguments to qmake, then the config.log will definitely contain different text.
(Also, remember to delete all the output files before you call qmake again)

Hi JKSH, I've solved now.
I tried to build the plugin from another PC and it worked right away.
The slashes instead of back slashes in MariaDB path was childs of various desperate tests.Thanks at all for help.
