Dynamic Linking

[Laws at SRI-AI.ARPA]

From:  Ken Laws <Laws at SRI-AI.ARPA>

Dynamic linking is available in Unix, or at least in any Unix that supports
Franz cfasl.  David Kashtan used that as a template to build a dynamic
linker for our system; now any C program can link new routines into its
own runtime image.  (We run Eunice, but the same technique should work
for any operating system.)

If you want to stick with traditional software, you can use system calls
to invoke the compiler and/or linker, then run the resulting image.  This
isn't full dynamic linking, but it can be good enough for compiling
highly efficient filters, Fourier transforms, image processing operators,
etc.  I have seen this technique used in U. Maryland image processing
code.
