boost.coroutine 1.58 fails to build for mingw because of undefined symbols

[anonymous]

Hello,

I'm trying to cross-compile boost 1.58 from linux for mingw from tarball for archlinux (aur.archlinux.org/packages/mingw-w64-boost/).

I'm stuck when linking boost.coroutine because I've got undefined references to symbols in boost.context (make_fcontext, jump_fcontext):

gcc.link.dll bin.v2/libs/coroutine/build/gcc-mingw-mingw64/release/binary-format-pe/target-os-windows/threadapi-win32/threading-multi/libboost_coroutine-mt.dll.a
bin.v2/libs/coroutine/build/gcc-mingw-mingw64/release/binary-format-pe/target-os-windows/threadapi-win32/threading-multi/detail/coroutine_context.o:coroutine_context.cpp:(.text+0x4a): undefined reference to `_imp__make_fcontext'
bin.v2/libs/coroutine/build/gcc-mingw-mingw64/release/binary-format-pe/target-os-windows/threadapi-win32/threading-multi/detail/coroutine_context.o:coroutine_context.cpp:(.text+0xc7): undefined reference to `_imp__jump_fcontext'

It looks exactly like this issue github.com/boostorg/context/pull/12 that was fixed for AIX.

Prior to the build I applied the fedora patch used to successfully build previous versions of boost for mingw: pkgs.fedoraproject.org/cgit/mingw-boost.git/tree/boost-mingw.patch, but maybe it needs updating. Also I wonder why it wasn't submited or accepted upstream.

I have the same here, Boost 1.58, using mingw32 4.9.1 on Windows x86 (toolchain provided by Qt 5.4 package)

...failed

I haven't used any patches, just following the build instructions on the 'Getting Started' page.
