However, more thanks go to Gonzalo, who hit the nail on the head.  I had
put 'extern "C"' around my header files, but then must have removed it in a
bid to try other options when I was still trying to link without the .so
libraries.  Now that extern "C" is back in place they link fine.

All solved now, thanks,
