I use the following code to determine memory values on a 32bit machine and succeed with no errors and correct data. However, when I try to use this code for a 64bit machine it chokes. The error output is: In function 'sysinfo' undefined reference to '__ia64_syscall'. ANY SUGGESTIONS!!!!!!!!!!!
*********************CODE*************************
**
#include <stdio.h>
#include <linux/unistd.h> /* for _syscallX macros/related stuff */
#include <linux/kernel.h> /* for struct sysinfo */
#include <linux/sys.h>

_syscall1(int, sysinfo, struct sysinfo *, info);

int main(void)
{
struct sysinfo s_info;
int error;

error = sysinfo(&s_info);
printf("code error = %d\n", error);
printf("RAM: total %d KB/ free %d KB\n"
"Swap: total %d KB/ free %d KB\n",
(s_info.totalram/1024), (s_info.freeram/1024),
(s_info.totalswap/1024), (s_info.freeswap/1024));

return(0);
}

Problem has been solved. A line of code needed removed...now it works fine.
