OS Specific 'use' statement	Can't Post

Hi All,

I have the following OS portability problem.

I want to 'use' a perl module in my code only if it is running under Windows. The module will not be available on Linux. But my code has to run on both Windows and Linux and I want the same code base to run on them.

In short I am looking for something like..

#if (OS is windows)
use WindowsModule.pm
#endif

Now statements like if($OSNAME eq 'Windows') does not work on this as I can not put the 'use' statement inside a regular 'if' condition.

If someone can think of a solution, can you please help me with this?

Biplab.

Use 'require' instead of 'use' to load the module.

Or, you could put your if block inside a BEGIN block so that it is executed during the compilation phase.

Code

use if $^O eq 'MSWin32' , 'WindowsModule';

I suggest you read the documentation for use.

You'll find references to both methods of solving your problem that FishMonger and rovf have mentioned.
