Experienced Win SWT team porting to OSX [message #522999] Wed, 24 March 2010 17:38 Go to next message

My team has an SWT app running on Windows. We have a lot of experience on Windows, but none on Mac. We have a client that would like a port of the SWT app on Macintosh. We know that several users will be running the app on Macs, but cannot specify a particular OS version other than that it will be OSX (not OS 9).

We will be running OSX 10.6 on a new IMac. We could use JRE 1.6 and 64-bit Eclipse, but our app (which is targeted to JRE 1.5) needs to be 32 bit and compatible with any version of OSX - and therefore 32-bit.

1. Will 32-bit SWT Cocoa run on all versions of OSX? The download page seems to imply only 10.5 and 10.6. Or do we need to use SWT Carbon?
2. Given the answer to 1, can we use 64-bit Eclipse and JRE 1.6 to develop the 32-bit app, or do we need 32-bit Eclipse and JRE 1.5?

Thanks!

Hi,

The Cocoa port runs on OSX 10.5 and newer, the Carbon port runs on OSX 10.4
and newer (if using Carbon on 10.6 note
http://www.eclipse.org/swt/faq.php#cocoa32launch ). If your app needs to
run on an older OSX than 10.4 then you'll need to use an older SWT release
that had this support (I think OSX 10.3 was the oldest ever supported,
either by Eclipse/SWT 3.3.x or 3.2.x).

You should be able to use a 64-bit eclipse release to develop a 32-bit app.
Just keep in mind that if you should stick to Java 1.5 API and earlier,
because JRE 1.6 is not available in a 32-bit flavour prior to OSX 10.6.
