Hello World in SystemC

Create two files and run it at the Shell prompt.

1. Edit the CPP file first.

// All systemc modules should include systemc.h header file
 #include "systemc.h"
 // Hello_world is module name
 SC_MODULE (hello_world) {
   SC_CTOR (hello_world) {
     // Nothing in constructor 
   }
   void say_hello() {
     //Print "Hello World" to the console.
     cout << "Hello World.\n";
   }
 };
 
 // sc_main in top level function like in C++ main
 int sc_main(int argc, char* argv[]) {
   hello_world hello("HELLO");
   // Print the hello world
   hello.say_hello();
   return(0);
 }

2. Then create a Makefile. This makefile is reusable for all SystemC projects.

SYSTEMC=/usr/local/systemc
LDFLAGS= -L$(SYSTEMC)/lib-linux -lsystemc
CXXFLAGS=-Wno-deprecated -I$(SYSTEMC)/include -fpermissive

all:
 g++ $(CXXFLAGS) *.cpp $(LDFLAGS)
 ./a.out

3. The command "make" compiles and runs the Hello World program.

$ make
g++ -Wno-deprecated -I/usr/local/systemc/include  *.cpp -L/usr/local/systemc/lib-linux -lsystemc
./a.out
