boost v1.71 - Program fails to compile after including header : <boost/process.hpp>

[m7b]

I dont't know if it is relatet to #92, but i can't compile the same source code with only the header included with boost 1.71.

Definitely a issue under MINGW, Small workaround for now: https://github.com/sinkingsugar/chainblocks/blob/5c6920d65daf22b169a3dfba9db63ef4f50814cd/src/core/blocks/process.cpp#L11

It also works if you define:

-DBOOST_USE_WINDOWS_H -DWIN32_LEAN_AND_MEAN

So I just added this to my CMakeLists.txt file:

# Boost.Process 1.71+ fails without windows.h.
# WIN32_LEAN_AND_MEAN avoids issues with asio.
# https://github.com/boostorg/process/issues/96
if(Boost_VERSION GREATER 107000)
  add_definitions(-DBOOST_USE_WINDOWS_H -DWIN32_LEAN_AND_MEAN)
endif()

It also works if you define:

-DBOOST_USE_WINDOWS_H -DWIN32_LEAN_AND_MEAN

I also had to #include <windows.h> myself.

[klemens-morgenstern]

Are all you guys using mingw? And does mingw work with boost.dll?

[Gei0r]

Yeah, I'm using mingw64 installed through MSYS2.
Haven't tried boost.dll.

[gibbontrothy]

I'm also using msys2/mingw64. I'm not sure what boost.dll means for msys2, but I do use static and dynamic linking.
