[LTP] Build failure with 2010-01-07 cvs

["Mitani" <mitani@ryobi.co.jp>]

Hi,

I tried to make with latest version (2010-01-07 cvs) in RHEL4.8
(2.6.9-89.ELsmp).
But it failed with following message:
------------
gcc -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall
-I/home/LTP/ltp-2010-01-07/testcases/kernel/include -g

------------

"numa_helpers.h" is as follows (comments are omitted):
------------
#ifndef LTP_NUMA_HELPERS_H
#define LTP_NUMA_HELPERS_H

#include "config.h"
#if HAVE_NUMA_H
#include <numa.h>

static inline void nodemask_set(nodemask_t *mask, int node)

{                                                       <----- L.81
        mask->n[node / (8*sizeof(unsigned long))] |=
                (1UL << (node % (8*sizeof(unsigned long))));
}

static inline void nodemask_dump(const char *header, const nodemask_t *mask)
{                                                       <----- L.95
        int i;
        EPRINTF("%s", header);
        for (i = 0; i < NUMA_NUM_NODES/(sizeof(unsigned long)*8); i++)
                EPRINTF(" 0x%08lx", mask->n[i]);
        EPRINTF("\n");
}

#else

typedef struct nodemask_t { };

static inline void nodemask_set(nodemask_t *mask, int node)
{
        return;
}

static inline void nodemask_dump(const char *header, const nodemask_t *mask)
{
        return;
}

#endif

#endif
------------

In my system, HAVE_NUMA_H is defined as 1.

The function "nodemask_set" defined in "/usr/include/numa.h" is same
as the one of "numa_helpers.h".
And the function "nodemask_dump" defined in "${LTPROOT}/testcases/kernel
/syscalls/utils/numa_helpers" is same as the one of "numa_helpers.h".

Why are the same definitions necessary in "numa_helpers.h" on purpose?


I'm glad if I get your help.


Regards--
