Error E0304 and C2665

[bruce]

Hello friend, I am super beginner. I am trying to run this example code http://www.asic-world.com/systemc/first1.html#Counter_Design_Specs  counter design and counter testbench on my  systemc with visual studio. So I got two error. Here I put the error together.

• Severity    Code    Description    Project    File    Line    Suppression State
  Error (active)    E0304    no instance of overloaded function "sc_start" matches the argument list    Project1    C:\Users\60182\source\repos\Project1\Project1\first_counter_tb.cpp    17    
   
• Severity    Code    Description    Project    File    Line    Suppression State
  Error    C2665    'sc_core::sc_start': none of the 4 overloads could convert all the argument types    Project1    c:\users\60182\source\repos\project1\project1\first_counter_tb.cpp    17

The example you are refering to is for SystemC 2.0 and more over has errors. Actually this is a bad example to start with.

• the sc_start() in line 17 needs to be commented out for 2 reasons: a) it doesn't make any sense and b) it runs elaboration and tracing (VCD) needs to be initialized before that. After elaboration you cannot add signals for tracing anymore
• sc_start() (lines 32, 34, 40, 42, 47, 49, 56 58) has to be called either without any arguments (so it runs to the end) or with a duration in terms of sc_time like this:

  sc_start(1, SC_NS);

   

My recommendation would be to either use  the Doulus tutorials: https://www.doulos.com/knowhow/systemc/tutorial/ or the stuff from SCLive (https://sclive.wordpress.com/)
