[Boost-users] [thread] Can't compile once.cpp for ppc in 1.54

Attempting to build the 1.54.0 version of the thread library for ppc on Mac OS X 10.6.8, using Apple's GCC 4.0, I get this error: boost_1_54_0/boost/atomic/detail/gcc-ppc.hpp: In member function 'bool boost::atomics::detail::base_atomic<T, int, 4u, Sign>::compare_exchange_strong(T&, T, boost::memory_order, boost::memory_order) volatile [with T = unsigned int, bool Sign = false]': /Volumes/Home/Mercurial/boost_1_54_0/boost/atomic/detail/gcc-ppc.hpp:1190: error: impossible constraint in 'asm' If I use GCC 4.2, I don't get the error. But I'm hesitant to use that compiler, because it usually produces code that won't run on G3's. -- James W. Walker, Innoventive Software LLC <http://www.frameforge3d.com/>
