dynamically loaded libraries

[mhearne808]

I have a question about how dynamically loaded C++ modules work, which
I will phrase as a hypothetical scenario involving the Numeric module.
Please understand that I don't really care about Numeric per se, it's
just a useful example of a module that defines a generally useful data
type.

Let's say I want to create a C++ Python extension module that has
methods accepting the Numeric array type as input, and also create
these arrays as output.

In order to make this work, do I have to statically link against the
Numeric source, or do I only have to include the headers, under the
assumption (??) that the Numeric functionality will be available
because the Python executable has dynamically loaded it?

Thanks!

Mike

You'll only need the dynamic libs. Of course they must be available on link-
as well as run-time.
