Thanks, John. I passed this patch to upstream through
https://github.com/ceph/ceph/pull/1844
I merged this, but shortly after Greg pointed out that using our
spinlock
implementation on this architecture might be better. Hard to say
either
way, though, knowing almost nothing about this architecture, and I
suspect
it would be more work to #ifdef around it than to simply #define this
variable.
The pthread spinlock and GCC sync support are probably better than the
atomic_ops
library on Linux. For hpux, it would be best stay with atomic_ops.
I have continued to hack trying to get ceph to build. I forced the
cast and reached the following
point:

There are two issues here:
1) I think "-latomic_ops" should be added to EXTRALIBS, not LDFLAGS in
the Makefile.
2) The libatomic-ops package doesn't work with c++ at least when
libatomic_ops.a contains
needed functions. The header file emul_cas.h the standard
#ifdef __cplusplus
extern "C" {
#endif
...
#ifdef __cplusplus
}
#endif
namespace stuff. There might be other places as well.
Hacking this got me to here:

Haven't had a chance to look at this one but it seems like a eglibc
bug. Note "-latomic_ops" is
added to EXTRALIBS in the above.
