Boost\libs\pool\test failed due to link error on MSVC

[QuellaZhang]

Issue description:
Found Boost\libs\pool\test boostorg/boost@38d8e0e link error in a future release of MSVC. Could you please take a look?

Reproduce steps:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git Boost\src
2. open a VS 2017 x64 command prompt and browse to Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\x64rel address-model=64
5. .\b2 variant=release --build-dir=..\out\x64rel address-model=64
6. .\b2 -j4 variant=release --build-dir=..\out\x64rel libs\pool\test

ErrorMessage:
Creating library .\pool_msvc_compiler_bug_test.lib and object .\pool_msvc_compiler_bug_test.exp
pool_msvc_compiler_bug_test.obj : error LNK2019: unresolved external symbol "public: __cdecl boost::archive::codecvt_null<wchar_t>::codecvt_null<wchar_t>(unsigned __int64)" (??0?$codecvt_null@_W@archive@boost@@qeaa@_K@Z) referenced in function "public: void __cdecl boost::archive::codecvt_null<wchar_t>::`default constructor closure'(void)" (??_F?$codecvt_null@_W@archive@boost@@QEAAXXZ)

I too am having a similar issue when statically linking boost::serialization to my application:

cmake_pch.obj : error LNK2019: unresolved external symbol "public: __cdecl boost::archive::codecvt_null<wchar_t>::codecvt_null<wchar_t>(unsigned __int64)" (??0?$codecvt_null@_W@archive@boost@@qeaa@_K@Z) referenced in function "public: v
oid __cdecl boost::archive::codecvt_null<wchar_t>::`default constructor closure'(void)" (??_F?$codecvt_null@_W@archive@boost@@QEAAXXZ)

I have tried building Boost 1.74.0 and 1.73.0 with ICU (1.67_1) support on Windows using MSVC2019 and then statically linking to my application. It would seem that sometime after Boost 1.70.0 symbol visibility was tinkered with.

I have the similar issue as @MichaelAnthonyP96 mentioned.

The environment is:

• OS: Windows 10 Pro version 21H1 build 19043.1110 with Windows Feature Experience Pack 120.2212.3530.0

• IDE: Microsoft Visual Studio 2019 Version 16.10.4

• library version: Boost 1.76.0 statically linking with cmake

The part of adding boost libs in cmake:

# Add boost library
# Reference: https://github.com/Microsoft/vcpkg/issues/4188
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED OFF)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(BOOST 76.0 REQUIRED COMPONENTS test serialization)
find_path(BOOST_INCLUDE_DIR boost)
include_directories(${BOOST_INCLUDE_DIR})
target_link_libraries(TinyDIP Boost::boost ${BOOST_LIBRARIES})
