Does Qt 5.0.0 MySQL Driver work for 64 bit on Windows?

soroush

Can anyone confirm using MySQL driver with Qt 5.0.0?
I'm going to report a bug for it.

Operating System: Windows 7 x64
MySQL version: 5.5.13
Qt: 5.0.0 x64
Compiler: MinGW x64

i don't think that it could be a problem if you use 64 bit version of MySQL connector. but i don't know if there's 64bit version of libmysql / mingw compiled version unless you have its source code and compile with the compiler of your choice.

64 versions of MySQL connectors are provided by Oracle. No problem with bitness in MySQL. plain C++ works perfectly. The issue is directly related to Qt not MySQL.

i'm using Qt5 W/msvc and mysql. works fine.

mysql.dll is a MSVC binary. I think that's the issue. I exported symbols to MinGW, though seems not working:
@
gendef libmysql.dll
dlltool --input-def libmysql.def --dllname libmysql.dll --output-lib libmysql.a
@

The strange fact is that I don't get any linkage error neither when compiling Qt nor application.

try adding "-k" option where calling "dlltool"

That is not matter of MySQL. Connectors work fine with mingw. It's all about Qt.
