Anyone using dbexpress driver for mysql with Mac OS X?
got a error message "Unknow driver: DevartMySQL Direct"

I called Direct Method, as below, which works fine for windows(with different libraryname)
SQLConnection.DriverName := 'DevartMySQL Direct';
SQLConnection.LibraryName := 'libdbexpmda40.dylib';

any idea what is wrong with it? or any working example code

Hello,

The point is that you set the incorrect driver name. To solve the problem, you should set the DriverName property to 'DevartMySQLDirect' (without spaces) instead of 'DevartMySQL Direct'.

I have tried DevartMySQLDirect without space, then the error message become "Unknow driver: DevartMySQLDirect"

To solve the problem, you should add the DbxDevartMySql unit to the USES clause of your unit.

I tried include the unit in Devart\Dbx\MySql\Delphi16\OSX32\DbxDevartMySql.dcu as below,
DbxDevartMySql in ".\dcu\OSX32\DbxDevartMySql.dcu";

now it will not compile, [DCC Fatal Error] : F2051 Unit DbxDevartMySql was compiled with a different version of Data.DBXCommon.TDBXDriverDef

I am using "Embarcadero® Delphi® XE2 Version 16.0.4276.44006"

also tried include
Devart\Dbx\MySql\Source\DbxDevartMySql.pas

got the same error message,if I remove it from the unit list, it will compile and works for windows only.

The point is that the latest dbExpress driver for MySQL version 5.1.3 requires Update 4 for RAD Studio XE2 (16.0.4429.46931). You can find a note about this in the dbExpress driver for MySQL revision history (the History.html file) and at our website at http://www.devart.com/dbx/mysql/compatibility.html . To solve the problem, you should install RAD Studio XE2 Update 4.
