Boost C++ Libraries: Ticket #10264: [smart_ptr] AIX 6.1 bug with sched_yield() function out of scope https://svn.boost.org/trac10/ticket/10264 The error that pops up in some of the lambda tests is the following: ../libs/lambda/test/algorithm_test.cpp:37:48: error: reference to 'var' is ambiguous <blockquote> protect((_1 = var(sum), ++var(sum))))); <blockquote> </blockquote> </blockquote> In file included from /usr/include/sys/thread.h:37:0, <blockquote> from /usr/include/sys/ptrace.h:28, from /usr/include/sys/proc.h:42, from /usr/include/sys/pri.h:43, from /usr/include/sys/sched.h:38, from /usr/include/sched.h:51, from ../boost/smart_ptr/detail/yield_k.hpp:101, from ../boost/smart_ptr/detail/spinlock_sync.hpp:18, from ../boost/smart_ptr/detail/spinlock.hpp:50, from ../boost/smart_ptr/detail/spinlock_pool.hpp:25, from ../boost/smart_ptr/shared_ptr.hpp:34, from ../boost/shared_ptr.hpp:17, from ../boost/test/utils/callback.hpp:21, from ../boost/test/execution_monitor.hpp:38, from ../boost/test/impl/execution_monitor.ipp:30, from ../boost/test/minimal.hpp:37, from ../libs/lambda/test/algorithm_test.cpp:14: </blockquote> /usr/include/sys/var.h:59:8: note: candidates are: struct var <blockquote> struct var { <blockquote> </blockquote> </blockquote> In file included from ../boost/lambda/core.hpp:53:0, <blockquote> from ../boost/lambda/lambda.hpp:14, from ../libs/lambda/test/algorithm_test.cpp:16: </blockquote> ../boost/lambda/detail/lambda_functor_base.hpp:66:19: note: template<class T> boost::lambda::lambda_functor<T> boost::lambda::var(const boost::lambda::lambda_functor<T>&) <blockquote> lambda_functor<T> var(const lambda_functor<T>& t) { return t; } <blockquote> </blockquote> </blockquote> ../boost/lambda/detail/lambda_functor_base.hpp:60:38: note: template<class T> boost::lambda::lambda_functor<boost::lambda::identity<T&> > boost::lambda::var(T&) <blockquote> inline lambda_functor<identity<T&> > var(T& t) { return identity<T&>(t); } <blockquote> </blockquote> </blockquote> In ../boost/lambda/detail/lambda_functor_base.hpp there is variable called var that conflicts with an AIX system variable. Defining var and later undefining it frees that variable name. However, the fix I propose is in the smart_ptr function.
