A const cast does remove the second error (and atomic_cas_ptr does seem like it
could have used a const argument, since this is the comparison arg, which
shouldn't be changed).
I still haven't gotten rid of the atomic_xor_uint_nv issue, though, so I can't
build the OpenSceneGraph on all our platforms. The code looks like:
_OPENTHREADS_ATOMIC_INLINE unsigned
Atomic::XOR(unsigned value)
{
#if defined(_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS)
return __sync_fetch_and_xor(&_value, value);
#elif defined(_OPENTHREADS_ATOMIC_USE_MIPOSPRO_BUILTINS)
return __xor_and_fetch(&_value, value);
#elif defined(_OPENTHREADS_ATOMIC_USE_SUN)
return atomic_xor_uint_nv(&_value, value);
#elif defined(_OPENTHREADS_ATOMIC_USE_MUTEX)
ScopedLock<Mutex> lock(_mutex);
_value ^= value;
return _value;
#else
_value ^= value;
return _value;
#endif
}
The line that complains that atomic_xor_uint_nv() needs a prototype is the one
inside the condition for _OPENTHREADS_ATOMIC_USE_SUN.
If anyone has an idea of a include I'm supposed to have, or something I'm
supposed to define, please help.
thanks,
andy

Subject: [osg-users] atomic_xor_uint_nv on Solaris
I'm trying to build a recent SVN version, and get errors for
include/OpenThreads/Atomic:
line 183: Error, badfunccp: The function "atomic_xor_uint_nv" must have a
prototype.
I'm not sure about this one. How is that supposed to be defined?
line 243: Error, badargtype2: Formal argument 2 of type void* in call to
atomic_cas_ptr(volatile void* void* void*) is being passed const void*const.
Is this one just a const issue? Should it use a const cast, or is this a sign
of a problem?
thanks
andy
