Compiling MySql plugin under Qt 5.14.2

[Anas]

Hi jsulm, Thank you for your answer this is what i find in the log :

I'm sorry i'm new on QT

[SGaist]

On your terminal picture, one thing that is wrong is the make call that is glued to the last ". Remove that completely. It's not part of the configuration process.

[Anas]

@SGaist i've read in an other forum that i should add it to make the mysql driver available, now by removing it i still have the mysql driver not available do you know please how to make it a yes

[jsulm]

@Anas Please check again the log file

[Anas]

@jsulm did you take a look at the screen i've posted ?

@Anas said in Compiling MySql plugin under Qt 5.14.2:

did you take a look at the screen i've posted ?

Yes, I did, but since you wrote "now by removing it i still have the mysql driver not available" it would make sense to check the log again.

@jsulm thank you for your answer now it's giving :

sorry for the quality of the screen

[jsulm]

@Anas Please post text and not screen shots.
sybfront.h header file is not found as you can see.
Take a look at https://forum.qt.io/topic/92626/cant-connect-to-mysql-database-qmysql-driver-not-loaded

[Anas]

@jsulm i've done everything as indicated in the post you sent me, i think it's not the same probleme :
-i've added the bin folders in the path ,
-i've redownloaded Mysql connector and installed it
-in the cmd.exe i enter : cd C:\QT\5.14.2\Src\qtbase\src\plugins\sqldrivers

• i run qmake -- MYSQL_INCDIR="C:\Mysql\MySQL Connector C 6.1\include" MYSQL_LIBDIR="C:\Mysql\MySQL Connector C 6.1\lib"
  it still gives me that Mysql is not available, and in the log i still have the same error sybfront.h is not found, how can i solve this please o how can i add this file if needed

[Anas]

it's so frustrating, Could anyone Help please ? or should i just delete QT and try something else !

Compiling the plugin should be easier than the loading problem.

The problem is not "sybfront.h is not found" in the last of the log, but "mysql.h is not found", in the middle of the log.
Your log showed that you are using C:\MySQL\MySQL Server 8.0
But later you said you run qmake with C:\Mysql\MySQL Connector C 6.1
So can you post the latest log?
But before that, are you sure mysql.h is in the C:\Mysql\MySQL Connector C 6.1\include folder?
Ah, and before run qmake again, delete config.cache file just in case.

P.S. For later convenience (avoiding the loading problem), if you are not using MSVC2015 version of Qt, I recommand that do not use MySQL Connector C 6.1.10-6.1.12, using 6.1.9 or older instead.

Thank you again for your help

@Anas According to the console, the mysql plugin seems to be loaded successfully.
Did you print the error message of the database?

    qDebug() << db.lastError().text();

And show your code please. (You can hide those ip/hostname, username and password things)

[Anas]

thank you very much Bonnie for your help it's working now, it was just a password probleme, thank you again
