Hi I am trying to compile ltp/testcases/kernel/sched/cfs-scheduler/
hackbench.c file and I am getting error like "error: 'PAGE_SIZE'
undeclared (first use in this function)
"
It seems macro for PTHREAD_STACK_MIN is defined as PAGE_SIZE but its
not able to find the declaration for PAGE_SIZE macro.
Any help in this regard is appreciable and find the error function and
include files below.
Thanks

Error function:

int err;
if (process_mode) {

switch (fork()) {
case -1: barf("fork()");
case 0:
(*func) (ctx);
exit(0);
}
return (pthread_t) 0;
}
if (pthread_attr_init(&attr) != 0)
barf("pthread_attr_init:");
#ifndef __ia64__
if (pthread_attr_setstacksize(&attr, PTHREAD_STACK_MIN) != 0) ---->
Error

#endif
if ((err=pthread_create(&childid, &attr, func, ctx)) != 0) {
fprintf(stderr, "pthread_create failed: %s (%d)\n",
strerror(err),
err);
exit(-1);
}
return (childid);
}
