Hi, I'm getting the following error when using BOOST_DLL_ALIAS to export a function to create a plugin using visual studio 2019 and boost 1.71. This isn't new, just the first time I've noticed it. E0077 this declaration has no storage class or type specifier I've cross-checked this with the example (specifically tutorial 2) to ensure that it wasn't just me. For reference, the offending line in the my_plugin_aggregator.cpp file is: BOOST_DLL_ALIAS( my_namespace::my_plugin_aggregator::create, // <-- this function is exported with... create_plugin // <-- ...this alias name ) Other than suppressing this specific error, is there any other work around given I'm compiling with treat warnings as errors enabled? Any help appreciated as always. Thanks, Sean.
