With the current version of Visual Studio Community (Version 17.8.6) and the current version of VCPKG (2023-12-12-1c9ec1978a6b0c2b39c9e9554a96e3e275f7556e) I have just started getting a compiler error that was not present before. I verified that with VS Community 17.8.5 and a slightly older cut of VCPKG, this error is not present.
(VCPKG was configured to build with the default x64-windows triplet. Nothing special was done there. My project is attempting to compile a DLL.)
The full error message is:
vcpkg_installed\x64-windows\include\boost\fiber\stack_allocator_wrapper.hpp(85,43): error C2491: 'boost::fibers::make_stack_allocator_wrapper': definition of dllimport function not allowed
This seems to be due to make_stack_allocator_wrapper attempting to export a templated function:
From boost\fiber\stack_allocator_wrapper.hpp:
template <typename StackAllocator, typename ... Args>
BOOST_FIBERS_DECL stack_allocator_wrapper make_stack_allocator_wrapper(Args && ... args)
{
return stack_allocator_wrapper(
std::unique_ptr<detail::polymorphic_stack_allocator_base>(
new detail::polymorphic_stack_allocator_impl<StackAllocator>(std::forward< Args >( args) ... )));
}
Has anyone else seen this or determined if this needs patched or otherwise has a way to correct it from client (my) code or CMake configuration?
