Building an Application Actor

This section assumes that you have built a chorus or kernonly system image in the build_dir directory. This example will create a simple Hello World actor.

1. Create a working directory where the actor will reside.

2. In this working directory, create a file named Imakefile containing the following lines:

   Depend(hello.c)
   EmbeddedSupActorTarget(hello_s.r,hello.o,)

3. Create a file named hello.c containing your Hello World program, written in C. For example:

   #include <stdio.h>
   
   int main()
   {
   		printf("Hello World!\n");
   		return(0);
   }

4. Generate a Makefile to build the actor, by typing the following command:

   % ChorusOSMkMf build_dir/Paths

   See ChorusOSMkMf(1CC) for more information about creating a Makefile.

5. Build the dependencies:

   % make depend

6. Build the application:

   % make

Your directory will now contain a supervisor actor, hello_s.r.
