Sikuli-framework does not work on Linux

[mandeepsandhu]

The current version of Sikuli - sikuli-java.jar, seems to be for the mac platform which cause it to fail under other platforms.

There are some platform specific libs which are included in the jar file (eg: files under META-INF/libs/ which contain platform specific shared objects) because of which the same jar file cannot be used across different OS platforms.

It'll probably be best, if we can reference Sikuli from an existing installation on the system rather than ship a platform specific jar.

There's another problem of Env.getOS() returning the wrong string when run on Linux. It returns MAC even on Linux. This is a known bug in the SikuliX jar.

[mandeepsandhu]

If we replace sikuli-java.jar with sikuli-script.jar (and change it in run.py as well), then basic things start working.

To make the calculator example work, I changed the path of the binary in calculator.py to the absolute path of the calculator application in Ubuntu for the MAC entry (as thats the OS string reported under Linux too, though this is just a temporary hack).

However, now it fails while trying to do a region match:

Done.

This was working before I pulled your changes. Somehow it's not after I updated my repo with the latest from upstream. Any idea what could be going wrong?

With latest version of Sikuli (1.0.1) it looks like they've changed a bunch of the classes around, previously I was patching their Region class to add some additional functionality. I am going to take this logic and put into a helper class instead and it should be more stable.

Good point for referencing jar from an installation, I'll look into this. Keep you posted.

Thanks again.
