[uml-devel] sysconf(_SC_NPROCESSORS_CONF) returning zero

[Stanislav Meduna <stano@meduna.org>]

Hi,

the following program

===
#include <unistd.h>
#include <stdio.h>

main()
{
   printf("Number of processors: %d\n", sysconf(_SC_NPROCESSORS_CONF));
}
===

produces

   Number of processors: 0

on my system.


# uname -a
Linux dirk 2.6.26 #1 Wed Jul 30 10:56:10 CEST 2008 i686 GNU/Linux

# cat /proc/cpuinfo
processor       : 0

# ls -l /lib/libc.so.6
lrwxrwxrwx 1 root root 11 2008-07-17 17:16 /lib/libc.so.6 -> libc-2.7.so


The monit monitoring tool (http://www.tildeslash.com/monit/)
crashes because of this. I don't know whose fault it is, but
I suspect the UML - otherwise I'd expect many more instances
of this problem when googling for it.
