including /usr/include/linux/ header files throwing errors in SLES 10.2
 
I am including /usr/include/linux/smp.h
/usr/include/linux/preempt.h
/usr/include/linux/config.h

in my source code,because the get_cpu() function needs these headers.
But I am getting errors

Can you help me in sorting out these errors....thnx in advance

estabroo 08-12-2008 11:01 PM
Wow your just looking for pain. Your mixing c, c++, and kernel headers. For the kernel headers you'll need to do a:

Code:
extern "C" {
#include </usr/include/linux/smp.h>
#include <usr/include/linux/preempt.h>
#include </usr/include/linux/config.h>
};
Most likely the function that your trying to use won't work anyway if this is a userspace program.

deedhnd 08-14-2008 06:22 AM
but i want to use the get_cpu() function in my program...
please tell me how to do it...??

estabroo 08-14-2008 02:25 PM
Well if you are running a new enough kernel (and new enough libc) you can use the getcpu system call.

man 2 getcpu

deedhnd 08-15-2008 09:36 AM
well i am using 2.6.16 kernel with gcc version 4.1.2

I am writing a sample program

extern "C"
{
#include<linux/smp.h>
#include<linux/preempt.h>
}
int main()
{
int result;
result=get_cpu();
return 0;
}

on compiling...
it gives the same set of errors...

Is there some way to remove these errors...
or any other way(other system calls or any assembly code) which can replicate the functionality of get_cpu()

estabroo 08-15-2008 10:28 AM
Looks like getcpu() syscall wasn't added until 2.6.19

you might want to try sched_getcpu()

Code:
extern "C" {
#define _GNU_SOURCE
#include <utpmx.h>
};

int main(void) {
  int result;
  result = sched_getcpu();
  return 0;
}

deedhnd 08-18-2008 03:32 AM
The above sched_getcpu() program also isnt compiling successfully saying
undefined reference to sched_getcpu()...

estabroo 08-18-2008 09:02 AM
Sorry then, I guess you either need to upgrade or find another way.

deedhnd 08-19-2008 07:50 AM
Is there any way to replace the functionality of get_cpu() with some other system calls which serves the same as get_cpu()??

or any other way...

Pls suggest ....I am stuck...

Thanx

deedhnd 08-19-2008 08:08 AM
the above suggested use of sched_getcpu() program gives undefined reference to sched_getcpu while linking........
