You may delete main.c.

using the makeEngine makefile.

Will update this now. Old files.

Thanks - it complies, but you still have two warnings which I would suggest you consider fixing.

Here's Mac exe for your repository

the warnings:

Code: Select all

src/movegentest.c(90): warning #181: argument of type "unsigned long" is incompatible with format "%d", expecting argument of type "int"
      printf("Seconds: %d\n",(end - start) / CLOCKS_PER_SEC);

src/uci.c(272): warning #1011: missing return statement at end of non-void function "getInput"
  }
  ^

this fixes it - you need to confirm that my fix is correct:

Code: Select all

    printf("Nodes  : %llu\n",total);
    printf("Seconds: %llu\n", (end - start) / CLOCKS_PER_SEC);

    ptr = strchr(str, '\r');
    if (ptr != NULL) *ptr = '\0';
	return(0);
}

Not home ATM. Will fix when I get back. Thanks for the help and thanks for the Mac version

[MikeB]

engine does not play under xboard - it calculates, but never makes a move
