setenv ccC /local/bin/gcc

Example Makefile

contains rules that will allow you to create an image algebra C++ program prog.c in your directory, then issue the unix command:

make prog

The C++ compiler CC will be invoked with prog.c as its argument. It leaves an executable copy in the file prog. This file may then be invoked by executing the command:

./prog

Example boundary finding program

is a program that will find the boundary of objects in a
