icpc with old style Kernighan & Ritchie C

[Arthur4]

Hello,

I have an old C program I need to compile. It's been written in the old style C from the original Kernighan and Ritchie standard:

myfunc(a,b)

int a, b;

{

/* code */

}

I have been asked to use icpc. I have installed the latest version of icpc available for download today (10/26/2021). It's not surprising that I'm getting lots of errors.

Is there a compiler flag for icpc that will allow me to compile this old program?

Thanks.

You can use icc instead of icpc on C file.

$ cat t2.c

#include<stdio.h>

int myfunc();

int myfunc(a,b)

int a,b;

{

  int c;

  c =a+b;

  return c;

}

$ icc t2.c -c

$

Thanks to Shivani and Viet. We have some company requirements on icpc, and I will wait for Shivani to determine whether there's a compiler flag that can be set to avoid having to use a different compiler or worse, rewriting that code!

AFAIK, there isn't an option so that icpc will accept the code. g++ won't compile it neither.

Thanks,

Sorry for the inconvenience. Unfortunately, there is no compiler flag for icpc that will allow you to compile the old C Program.
