Before compiling Report Manager engine with Delphi/Builder/Kylix you can customize the engine.
The compiler defines allow you to disable engine capabilities to reduce executable size, other way to reduce the executable size is compile with runtime packages.
| Compiler Defines | |
| Name | Includes |
| USESQLEXPRESS | Allow the use of all DBExpress drivers |
| USEIBX | Allow the use of Interbase Express Native access |
| USEADO | Allow the use of Microsoft Data Access Objects including ODBC compatible drivers |
| USEBDE | Allow the use of Borland Database Engine and also the SQL Links technology |
| USEIBO | Allow the use of Jason Wharton's Interbase Objects |
| INDY10 | Use indy components in version 10, experimental |
To enable or disable this defines you must modify rpconf.inc file, for example to allow all database drivers but Interbase Objects the first lines of rpconf.inc:
// Database drivers to be used
{$DEFINE USESQLEXPRESS}
{$DEFINE USEIBX}
{$DEFINE USEADO}
{$DEFINE USEBDE}
//{$DEFINE USEIBO}
To enable a engine capability you must have the correct libraries, for
example to enable IBObjects you must have his units in the library path.
Some Defines are automatically disabled (later in the same file) after version checking so if you define USESQLEXPRESS but Delphi 5 compiler version is found the define will be disabled.
