Compiling Boost.log with Oracle Developer Studio 12.5, we see the following failure: % "CC" -std=c++11 -library=stdcpp,CrunG3 -xO4 -mt -erroff=%none -m32 -KPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_ATOMIC_DYN_LINK=1 -DBOOST_CHRONO_DYN_LINK=1 -DBOOST_DATE_TIME_DYN_LINK=1 -DBOOST_FILESYSTEM_DYN_LINK=1 -DBOOST_LOG_BUILDING_THE_LIB=1 -DBOOST_LOG_DLL -DBOOST_LOG_HAS_PTHREAD_MUTEX_ROBUST -DBOOST_LOG_WITHOUT_DEBUG_OUTPUT -DBOOST_LOG_WITHOUT_EVENT_LOG -DBOOST_SPIRIT_USE_PHOENIX_V3=1 -DBOOST_SYSTEM_DYN_LINK=1 -DBOOST_SYSTEM_NO_DEPRECATED -DBOOST_THREAD_BUILD_DLL=1 -DBOOST_THREAD_DONT_USE_CHRONO=1 -DBOOST_THREAD_POSIX -DBOOST_THREAD_USE_DLL=1 -DDATE_TIME_INLINE -DNDEBUG -D_XOPEN_SOURCE=500 -D__EXTENSIONS__ -D__STDC_CONSTANT_MACROS -D__typeof__=__typeof__ -I"../../.." -I"../../../libs/log/src" -c -o "../../../bin.v2/libs/log/build/sun/release/stdlib-gnu/threading-multi/posix/ipc_reliable_message_queue.o" "../../../libs/log/src/posix/ipc_reliable_message_queue.cpp" "../../../libs/log/src/posix/ipc_reliable_message_queue.cpp", line 61: Error: #error Boost.Log: Native 32-bit atomic operations are required but not supported by Boost.Atomic on the target platform. This seems to be a configuration issue. The following changes seems to work: 1) In boost/atomic/detail/platform/platform.hpp % !diff diff ./platform.hpp ./platform.hpp_orig 46c46 < #elif (defined(__GNUC__) || (__SUNPRO_CC >= 0x5130)) && (defined(__i386__) || defined(__x86_64__)) ---

The above change causes the compilation to proceed further, however, it fails again with another configuration issue causing failure to build atomic library "CC" -std=c++11 -library=stdcpp,CrunG3 -xO4 -mt -erroff=%none -m32 -KPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_ATOMIC_DYN_LINK=1 -DBOOST_ATOMIC_SOURCE -DNDEBUG -I"../../.." -c -o "../../../bin.v2/libs/atomic/build/sun/release/stdlib-gnu/threading-multi/lockpool.o" "../../../libs/atomic/src/lockpool.cpp" "../../../boost/atomic/detail/ops_gcc_sparc.hpp", line 69: Error: The function "fence_before_store" must have a prototype. In boost/atomic/detail/ops_gcc_sparc.hpp, the following change seems to resolve the issue % !diff % diff ./ops_gcc_sparc.hpp ./ops_gcc_sparc.hpp_orig 69c69 < fence_before(order); ---

I will submit a PR for this change. Thanks, Aparna
