Thanks for your answer.

Well, not necessarily, I find. 'info gcc' recommends one do explicit
instantiation, but you are certainly correct that 'g++' can sort this out.

I inherited a number of makefile includes from the source tree, and one of
them turns off the automatic template processing. I expect to change that
setting.

I am totally green at this, but I think any template used to create an
object member would create the linkage error unless it was either
automatically or explicitly instantiated somewhere (anywhere, I guess) in
the code.
