Hello,
I'm trying to build hwloc on a cray machine with cray compiler
:/opt/cray/craype/2.5.4/bin/cc
I get the following error :
$> CC=cc ./configure --prefix=$PWD-cc-install
$> make
Making all in src
make[1]: Entering directory `/home/j0306818/xavier/hwloc-1.11.5/src'
CC bitmap.lo
CC-147 craycc: ERROR
Declaration is incompatible with "int ffsl(long)" (declared at line 526 of
"/usr/include/string.h").
Total errors detected in bitmap.c: 1
make[1]: *** [bitmap.lo] Error 1
make[1]: Leaving directory `/home/j0306818/xavier/hwloc-1.11.5/src'
make: *** [all-recursive] Error 1
Do you have any idea of what I am doing wrong ?
Is this a known issue ?
Another secondary question :
Hwloc builds correctly with gcc compiler but the CPUVendor field is not
available using this code :
#include <hwloc.h>
int main(int argc, char *argv[])
{
hwloc_topology_t topo;
hwloc_obj_t obj;
int err;
int i;
char obj_str[2048];
char attr_str[2048];
/* initialize a topology context */
err = hwloc_topology_init(&topo);
assert(!err);
/* insert optional topology configuration here */
/* build the topology created and configured above */
err = hwloc_topology_load(topo);
/* play with the topology here */
obj = hwloc_get_obj_by_type(topo, HWLOC_OBJ_PACKAGE, 0);
fprintf(stdout, "CPU_Vendor : %s \n",
hwloc_obj_get_info_by_name(obj,"CPUVendor"));
hwloc_obj_type_snprintf(obj_str, 2048, obj, 1);
hwloc_obj_attr_snprintf(attr_str,2048, obj, " | ", 1);
fprintf(stdout, "%s : %s\n", obj_str, attr_str);
/* terminate this topology context */
hwloc_topology_destroy(topo);
return 0;
}
Am I using the correct code to retrieve the CPUVendor ? As far as I see the
topology is correctly detected anyway.
Regards,
XL.
