Separate 32 and 64 bit versions of libraries

in Integration and Hardware • 2 years ago

The release notes for Processing REV 0193 (8 March 2011) mentions:

+ Added support for separate 32 and 64 bit versions of libraries.

Does anyone have any more information on this. What does it mean exactly, how do we move between 64bit and 32bit libraries?

I have to run a 64bit version of java (so that I can load large amounts of data into processing), but this means that some of the libraries that I want to run (play with) such as the Kinect libs don't work because they need a 32bit version of java to run on. Is there a way that I can run both 32 and 64bit versions of java on my machine and swap between them at will?

I don't have more information on this, and I don't use the 64bit version of Java...
But I suppose that at best, it means that the native libraries used by Processing (core libraries), like Windows' DLLs, exist in 64bit version as well as the old 32bit version.
I don't think you can switch between them, I suppose it is Java picking up the right library depending on the version you use.
And of course, it won't change the external, contributed libraries: if they use themselves native libraries, they have to supply themselves the 64bit versions.

More educated guesses than real information, sorry... If somebody is more knowledgeable in this field and know better, just correct what I wrote, if needed.
