Cross-Platform Development
From Real Software Documentation
Using Target Flags
You can develop your application on one platform and compile it for any other platforms that Real Studio supports. If your application will run on more than one platform, you can use the following global Boolean constants to determine which type of code is currently executing.
| Boolean Constant | Description |
|---|---|
| DebugBuild | The application is running within the Real Studio application, i.e., from clicking the Run button in the IDE toolbar. |
| RBVersion | Returns the version of Real Studio that is being compiled. You can use this in an expression that evaluates to True or False to determine which version of Real Studio is compiling the application. |
| TargetBigEndian | The compiled application is running on a machine and OS that uses the Big Endian byte ordering. |
| TargetCarbon | The compiled application is currently running Carbon/Mac OS X code. |
| TargetCocoa New in 2010r3 | The compiled application is currently running Cocoa/Mac OS X code. in Real Studio 2010r3, Cocoa is being made available as a "beta" release. |
| TargetHasGUI | The application has a GUI, i.e., it is not a ConsoleApplication or a ServiceApplication. |
| TargetLinux New in 5.5 | The compiled application is running Linux code. |
| TargetLittleEndian | The compiled application is running on a machine and OS that uses the Little Endian byte ordering. |
| TargetMachO New in 5.5 | The compiled application is running on Mac OS X, running object code in the format for the Mach kernel. |
| TargetMacOS | The compiled application is currently running Macintosh code, for either Cocoa or Carbon frameworks. |
| TargetWin32 | The compiled application is currently running Win32 code. |
| Targetx86 | The compiled application is currently running on x86 hardware, regardless of OS. |
Conditional Compilation
If some of your code should be compiled only for a particular target platform (such as AppleScript-specific code or Declare statements), you can use #If statements to compile that code only for the appropriate platform. Use the following structure:
