[Coco] Drivewire on an original Raspberry Pi

[Rocky Hill]

 Very nice, can you share a link to the source? Were you able to compile it?

 I managed to locate the correct 4.2.3.4 eclipse-swt java source which 
came with the C source for the system libraries (libswt-*.so).

I modified the build script to recognize ARM64 (aarch64) and built the 
required .so libraries.

And ........

they work.

I now have DriveWire4 working on both Ubuntu 20.04 (or later) on both 
AMD64 (X86) and ARM64.

Regards

Walter
