Hello Olivier,

check the mysql site for a Win64 C-Connector if you want to do 64 Bits Applications.

Hello Olivier,

I don't see anything set for the LibraryLocation property. Please put the correct library there, like 'C:\Program Files\MySQL\Connector-C\libmysql.dll' - or whatever is correct for your setup.

If you get the exception that the library was found but could not be loaded that basically means exatly that - Zeos couldn't load the library and doesn't know why. The wrong bitness is just a guess. It could be that the library has the wrong bitness - but it also could be that the library failed to load because of missing dependencies like other DLLs. Maybe you want to check these things with the dependency walker.

With best regards,

Jan

At me: it works without any problem (Delphi XE2 32/64; ZEOS 7.3 svn 3986).

Michal

Thank you Miab3

i'll install this version and i'll inform you after

Olivier

Hi,

It's work fine with Zeos 7.3.0-alpha and LibMariaDB.dll 64bits

Thank you
