I have a quick question about the difference between the 32 and 64 bit version of Eclipse. I need to know what the difference is between the actual downloads, not the differences in performance or anything like that.
My situation is this: I have set up a development environment for an Eclipse project (Java) using 64-bit Eclipse, versioned the files in Subversion, and found out after the fact that we MUST develop on a 32-bit OS because of constraints for other parts of this project. Rather than have to download and set up a whole different instance of Eclipse, is it as simple as replacing the EXEs that launch Eclipse with 32-bit versions? Or are there other files that would have to be replaced?
Main difference, SWT. The core UI library used by Eclipse. You need the 64-bit version if you run on a 64-bit VM.
SWT is a native library used by Eclipse for it’s UI. This makes Eclipse a mix of Java and Native code.
