[SOLVED] - MYSQL driver Found but not Loaded in Windows XP / 2003

SGaist

Hi,

Are you sure that the MySQL dll's can be found by the application e.g. is the folder containing them in the PATH environment variable ?

ypspef

Yes. In my case the libmysql.dll is located at C:\Program Files\MySQL\MySQL Connector.C 6.1\lib\ that it is already in the path.

SGaist

Then, did you check the PATH environment variable in Qt Creator in the Run panel ?

ypspef

Yes. Also there. Actually it is defined at operating system level.

Hi, do you get the same error in Release build (instead of Debug)?

I have the same problem on Qt 5.4,I use Qt in Windows 7 and Mint17.I have tried " Release build",but error still exist.

And when I get the debug infomation,I find that it says:

libqsqlmysql.so: (/usr/lib/x86_64-linux-gnu/libmysqlclient_r.so.16: version `libmysqlclient_16' not found (required by /opt/Qt5.4.0/5.4/gcc_64/plugins/sqldrivers/libqsqlmysql.so))"

but I just have libmysqlclient_r.so.18... ...
though I make symbolic links,It still doesn't work

SGaist

You need to either install the .16 version or rebuild the plugin against your .18 version

... same error on release version ...also now using Qt 5.4 ...

Hi, googled a bit on why your MySQL Connector/C version 6.1.5 does not load and found some bad news: it seems starting with MySQL version 5.6 using it on Win XP or Win2K3 "is no longer supported":http://dev.mysql.com/doc/relnotes/connector-c/en/news-6-1-2.html (not a happy new year :-(

Thanks for your answer !!! ...
So I think that in machines with XP or 2003 I'll use another DB.
