Re: [Gems-users] Help ~ when build Opal

[Konstantinos Nikas <knikas@xxxxxxxxxxxxxxxxx>]

Hi,

I had the same problem last week. The problem is that the default case 
for opal is simics2.0. I had to change line 516 in simdist12.C to
#if 1    /* For Simics 3.0 or 2.2.X ONLY */
void *mm_malloc(size_t sz, size_t typesize, const char *type,
               const char *file, int line) {
#undef malloc
 return (malloc(sz));
}

Hope this is the right solution

Regards,

Kostas
