Question : Exporting variables from module on windows

The code I've posted will work on linux. But when I try to run it on Windows, I get the following error:

Global symbol "%hash" requires explicit package name at H:\test.pl line 6.
Execution of H:\test.pl aborted due to compilation errors.

I've declared %hash in test.pm with "our". I have %hash in the @EXPORT array. Why would I get this error when the exact same code works on linux?

Answer : Exporting variables from module on windows

I have found the problem... took me awhile...
It just happened that there's already a module called test.pm under C:/Perl/lib/test.pm and that module takes precedence over your module.
Here are the choices:
* use 'use lib' for force Perl to use your test.pm (use lib qw(/your/dir);)
* or better, use another name for module, such as MyTest.pm (example below)

BTW, you should only export when needed.
Otherwise using something like %MyTest::hash is probably a better (more explicit) way to go.

Good luck!
