I think you are mixing hwloc libraries here. CPUType was removed a while
ago (except on Solaris). And CPUVendor was widely added later.
My feeling is that your lstopo uses a recent libhwloc while your test
program uses an old one.

Hello Samuel,
With my test I get :
CPU_Vendor : (null)
Socket : CPUModel="Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz" | CPUType=x86_64
Meanwhile, the CPUVendor Field is in the generated xml.

Yes, with no warning, and I can also execute my a.out.
$> cc toto.c
$> ./a.out
$> cat toto.c

return __builtin_ffsl((unsigned long) argc);

Does this even build with the cray compiler?

{
return __builtin_ffsl((unsigned long) argc);

Indeed,
If I had a #undef __GNUC__ in misc.h the compilation finished (I still have the
link complaining about recompiling with -fPIE and linking with -pie, but I
should be able to handle that)
I tried all available cray cc (2.2.1 and 2.5.6) and they behave the same.
I'll see how to report bug t
Ah ok now I remember we've seen the same issue 4 years ago.

Basically the Cray compiler claimed to be GCC compatible it was not. But
that users explicitly requested the cray compiler to behave as GNU with
"-h gnu". Did you pass a

Do you mean __GNUC__? And which value does it have?
In other words: what, exactly, actually gets included from that file?
:)

It seems that the __GNU__ is defined so I don't get into the HWLOC_HAVE_FFSL
section.
Maybe because I already configured once with gcc before ? Do I have to do
anything more than make clean an reconfigure to change compiler ?

configure seems to have detected ffsl() properly, but it looks like our
ffsl() redefinition gets enabled anyway, and conflicts with the
system-wide one.
Does it help if you comment out line #66 of include/private/misc.h ?
extern int ffsl(long) __hwloc_attribute_const;

The code looks right and works here. What output do you get? Could you
post the output of

Hello Xavier
Can you send the /usr/include/string.h from that cray machine, your
config.log and include/private/autogen/config.h from the hwloc build
directory?
Do you get the same error if building from the default compiler instead
of /opt/cray/craype/2.5.4/bin/cc?
thanks
