[news.eclipse.platform.rcp] Which native libraries for RCP application?

[Jean Bovet <jean.bovet@xxxxxxxxxx>]

Hi,

I'm trying to figure out which libraries are needed for my RCP 
application to run on other platform than Windows. I downloaded the 
platform specific packages from the Eclipse download page (under the RCP 
Runtime Library). Let's take for example Linux 32 bits. The only native 
library I can see in the downloaded package is:
- org.eclipse.swt.gtk.linux.x86-3.5.0.v3550b.jar

However, in the main distribution of Eclipse, I can also find this library:
- org.eclipse.core.filesystem.linux.x86-1.2.0.v20080604-1400.jar

Is the filesystem library needed on Linux? Or should I only rely on what 
I downloaded for the RCP runtime? Why this difference?

Thanks,

Jean
