This is Crafty SE and I got the same thing, the issue is Mike choose to place
this in the chess.h file which in included in almost every other .c file in
crafty. This can only be initialized once so the best solution is to place all
of the code at the end of the chess.h file after the
/* if defined(TYPES_INCLUDED) */
in a new .h file for example mb.h . Then in the option.c file add the following;
#include "mb.h"
This will fix this problem but there is one other I have not been able to solve
that deals with the seedMT code that is in the option.c file. I get the error of
c:\devel\Crafty-SE\option.c(6651) : error C2371: 'seedMT' : redefinition; differ
ent basic types
c:\devel\Crafty-SE\option.c(6687) : warning C4142: benign redefinition of type
The section of code that is causing this is;
void seedMT (uint32 seed)
{
register uint32 x = (seed | 1U) & 0xFFFFFFFFU, *s = state;
register int j;
register int k;
k= ReadClock(time_type);
x= ((k%2==0) ? k+1 : k) ; // forces an odd number to be the seed
for(leftrnd=0, *s++=x, j=N; --j;
*s++ = (x*=69069U) & 0xFFFFFFFFU);
}
