Hi, try this

1. Install MySql server with libs (for exam C:\MySQL)
2. Install QtSDK with source (for exam C:\QtSDK)
3. Run Qt 4.7.3 for Desktop (mingw)

Test:
qDebug() << QSqlDatabase::drivers();
must be (“QSQLITE”, “QMYSQL3”, “QMYSQL”)

hello
This I also found on the Internet.
But I do not know how to do Step 3.
Should I make a new project with Qt Creator. Or something else?

I edited step 3 above for formatting. The individual steps had run together.

something else )

Run (round button) – All programms – Qt SDK – Desktop – run Qt 4.7.4 for Desktop (mingw) – step 3

Thanks for the responses.

I see now that I have Qt 4.8.0.
If I try this code “QTDIR = C: \ QtSDK \ QtSource \ 4.8.0”.
I get the following error: “QTDIR is not recognized internal or external command,”

No, the command is:

You’re assigning “C:\QtSDK\QtSource\4.8.0” to a variable called “QTDIR”

be carefully not “QTDIR = C: \ QtSDK \ QtSource \ 4.8.0”

must be “set QTDIR = C:\QtSDK\QtSource\4.8.0”

It doesn’t work.

Yes that works.

Oh yes, its doesn’t work.
please write to

“set QTDIR = C:\QtSDK\QtSource\4.8.0”

But now i have another error.

Is your QtSDK installed in C:\QtSDK, or E:\QtSDK? Your first “set” command is using E: not C:

And it’s supposed to be “set QTDIR= “ not “set QTDIR- “

Also, it should be “set mySQLDIR= “ not “set mSQLDIR- “

And when you do the “cd”, it should take you to whatever directory has the “mysql.pro”, not remain in system32.

My QtSDK is installed in E:\QtSDK.
I have found mysql.pro in the map “E:\QtSDK\QtSources\4.8.0\src\plugins\sqldrivers\mysql”.
libmysql.lib in the map C:\MySQL\MySQL51\lib\opt.

I saw that I had forgotten something.

I think I’m one step further.

but I get 2 errors.
