A quick appendum to Phil Keslin's note:

 If you are writing a DSO for loading into a performer app,
you will need something like the following in your makefile.

# DSO
Shared.so: Shared.o /usr/lib/libimage.a
        $(LD) -shared Twister.o -all -limage -o $++at++

The -all is necessary for the iopen function to be included.
