Make command failing

[Kishore17]

Hello Everyone,

I have just started to learn system C and I have installed the 2.3.3 version on my linux system 18.04. I have tried installing in usr/local as well as in the local directory (for example : In the downloads itself). I have a very simple hello world program, but i have an error. I feel it is the problem with the installation, any help is highly appreciated. Thank you very much in advance.

 

lugia@celebi:~/SystemC$ make
Makefile:56: *** SYSTEMC_HOME [/usr/local/systemc-2.3.3/] is not present. Please update Makefile.config.  Stop.
lugia@celebi:~/SystemC$ make

lugia@celebi:~/SystemC$ make

Makefile:109: recipe for target 'hello.o' failed
make: *** [hello.o] Error 1
lugia@celebi:~/SystemC$ 

The error is as stated above.

The code is as below.

#include <systemc.h>
using namespace std

SC_MODULE (hello_world) {
  SC_CTOR (hello_world) {
  }

  void say_hello() {
    cout << "Hello World SystemC-2.3.1.\n";
  }
};

int sc_main(int argc, char* argv[]) {
  hello_world hello("HELLO");
  hello.say_hello();
  return(0);
}

and my make file is as follows
