Boost日志链接错误（Cmake Mingw32）

Question

I have this cmake file:

cmake_minimum_required(VERSION 3.6)

find_package(Boost 1.54.0 REQUIRED COMPONENTS log)

add_executable(TestProject main.cpp)

target_include_directories(TestProject PUBLIC ${Boost_INCLUDE_DIRS})
target_link_libraries(TestProject Boost::log)
add_definitions("-DBOOST_ALL_NO_LIB") # Disable boost auto-linking.
add_definitions("-DBOOST_LOG_DYN_LINK") # Avoid linking errors with boost::log

If I build it using Visual Studio as my generator from a Visual-Studio developer console, I can build just fine. However in my MinGW32 environment I get linker errors. I can confirm that boost is installed in my mingw32 environment and is working well for other projects (which use other boost components).

I build with:

$ mkdir buildmsys && cd buildmsys
$ cmake .. -GNinja
$ cmake --build .

And here is the output

What's wrong with my setup?

Note: I've already checked (and tried) these links in case my question was a duplicate:

• Mingw32 Boost Log Link Errors: InterlockedCompareExchange (migration issue)

• boost log link error 2019 (BOOST_LOG_DYN_LINK issue)

• Boost-log linker error (Unicode issue)
• link error with boost log (Unicode issue)
• Visual Studio 2013 Boost-log v1_61_0 linking errors (boost installation issue)

If I look at those solutions, the unicode one is the only one I haven't gotten to work. I've added add_definitions("-Zc:wchar_t") to my Cmake file, but I get an unrecognized command line option error from c++.exe (since that flag is VS-specific).

Answer 1

The problem is likely caused by mismatch of the target Windows version between your code and Boost.Log. See this answer:

Problems Linking boost log 1_60 with MinGw on Windows 7

Most likely, your project defines _WIN32_WINNT somewhere to a value of 0x0600 or higher.

Boost defaults to Windows XP when compiled by MinGW because Windows SDK provided by MinGW is too incomplete.
