Build MySql driver in Windows Vista
Hello everyone,
straight to te point: how to build MySql driver under Windows Vista?
I've just made a MySql application that works in Xp, but fails to load driver in Vista, so I thought maybe this is dued to in-Xp-built driver. Anyway the problem could be common.
Trying to build it following documentation's instructions leads me to a serie of linker errors (follows a snip).
If you can point me to a verbose and working tutorial would be good too!
Suggestions are welcome here :)

Re: Build MySql driver in Windows Vista
I know, it will be unrelated but you can use QODBC with MySQL ODBC connector under Windows. It is easier than compiling MySQL driver in my opinion.
Re: Build MySql driver in Windows Vista
Take a look here: http://osum.sun.com/group/escomipnos...do-driver-para
He wrote a pdf about it (in Spanish ).
Look easy to follow ... i would try it myself but ... divorced from Wiandow$ ;)

LOL
Yes it was easy to follow and it works!
My luck is that I am Italian, so I can understand Spanish somehow, they are similar.
Anyway I'm going to ask for authorization to the author to translate it in English and Italian, it would be very helpfull!
Thank you very much graciano!
Re: Build MySql driver in Windows Vista
...BUT!... :)
Everything has compiled well and I got my wonderfull dll, anyway it works at home, but in my office Vista deploy pc it doesn't: it keeps saying "driver not loaded"...
ENVIRONMENT:
application dir (C:\Application):
Quote:
application.exe
QtCore4.dll
QtSql4.dll
QtGui4.dll
libmySQL.dll
mingwm10.dll
sqldrivers<dir> -> qsqlmysql4.dll
it can't connect because (it says) it can't load the driver, QApplication::libraryPath() says:
well... my ideas are over, here is required a genius flash!
Debug hints over there? :)
Re: Build MySql driver in Windows Vista
copy qsqlmysql4.dll, run Dependency Walker on it and check what is missing, copy or add to system Path rewuired dlls.
copying qsqlmysql4.dll one dir up is only for running Dependency Walker to make him see Qt dlls and libmySQL.dll so after that you can delete it cause your app will load it from sqldrivers dir
Re: Build MySql driver in Windows Vista
Thank you for the hint! But I have no Dependencies Walker.
Instead I found solutio after re-making the driver in the Vista pc in subject.
Solution seems to be libmysql.dll, I copied the one in MySQL\bin folder when instead I had to copy the one generated just before in MySQL\lib\opt.
Now it works and as always you men rock! :)
T h a n k y o u !
