How to create the plugin of MYSQL for Qt
-
OK now I have installed the sources (maybe) and I have a folder called Src, this is my path: C:\Qt\5.3\Src.
I try to follow the tutorial but in my situation when prompt "reimp libmysql.dll" I receive this message:
"reimp: libmysql.dll: invalid or corrupt import library"
but if prompt "reimp libmysql.lib" seems to work.
-
now I'm arrived to step 5 but I think I have some problem, this is the ouput after lunch the command:
configure.exe -debug-and-release -platform win32-g++ -qt-sql-mysql -l mysql -I C:\mysql\include -L C:\mysql\lib
Creating qmake...
mingw32-make: Nothing to be done for 'first'.
Running configuration tests...
g++: error: CreateProcess: No such file or directory
mingw32-make: *** [arch.o] Error 1
Could not find output file: No such file or directory
WARNING: The DirectX SDK could not be detected:
There is no Direct X SDK installed or the environment variable "DXSDK_DIR" is
not set.
Disabling the ANGLE backend.WARNING: Using OpenGL ES 2.0 without ANGLE.
Specify -opengl desktop to use Open GL.
The build will most likely fail. -
Either install the Direct X SDK or pass -opengl desktop to configure
-
I'm sorry and frustrated but
but unfortunately for me it is the first time with C++ and QT.
I lunch configure:configure.exe -opengl desktop
and the result is:

Just one question, do you only need to build the MySQL plugin ? If so, there's no need to rebuild Qt completely
-
This is the first time for me with C++ and QT so for me it's all new and I do not know what are the requirements needed to achieve my goal.
I want to make a windows application that keep some signal from a RFID antenna attached to notebook from serial and store data in a mysql database.
To start I want only to connect to mysql database and read a table data.So I guess I need only mysql plugin.
-
Then just compile the MySQL plugin like described in the documentation, no need to rebuild everything.

What does that message have to do with the current question ?

Can you be more specific ?

I m sorry for not being able to reply ^^ cause i ve moved to the web development world for a moment, thus i have forgotten about this post! anyway the instructions i did were for Windows, but i never tried the other platforms tough :/ sorry! @massum, and a big thanks to @SGaist ^^
-
Each platform has it's own gotchas but the *nix variants are generally more easy to deal with when it comes to dependencies like MySQL
You're welcome :)

Why cannot QSqlQuery execute "exit" sentence, but can execute other general query sentences?
Do not duplicate posting because you do not get an answer immendiately.
[edit:koahnig see https://forum.qt.io/topic/82629/why-qsqlquery-exec-exit-failed ]
