You might consider also using proc if getauxval is not available ?
unsigned long hwcap = 0;
#ifdef HAVE_GETAUXVAL
hwcap = getauxval (AT_HWCAP);
#else
unsigned long data[2];
FILE *f = fopen ("/proc/self/auxv", "r");
if (f == NULL)
return;
while (fread (data, sizeof (data), 1, f) > 0)
{
if (data[0] == AT_HWCAP)
{
hwcap = data[1];
break;
}
}
fclose (f);
Regards,
Antoine
