提升日志链接错误(Cmake Mingw32)

Question

我有这个cmake文件：

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

如果我使用Visual作为我的生成器从Visual开发人员控制台构建它，我就可以构建得很好。然而，在我的MinGW32环境中，我会得到链接器错误。我可以确认boost安装在我的mingw32环境中，并且在其他项目(使用其他boost组件)中运行良好。

我建造的是：

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

这是输出

我的装置怎么了？

注意:我已经检查(并尝试过)这些链接，以防我的问题是重复的：

• 移民问题( Mingw32 Boost Log Link Errors: InterlockedCompareExchange )
• boost log link error 2019 (BOOST_LOG_DYN_LINK发行)
• Boost-log linker error (Unicode发行)
• link error with boost log (Unicode发行)
• 0 linking errors (boost安装问题)

如果我看看这些解决方案，unicode 1号是唯一一个我还没有开始工作的解决方案。我已经将add_definitions("-Zc:wchar_t")添加到我的Cmake文件中，但是我从c++.exe获得了一个无法识别的命令行选项错误(因为该标志是VS特定的)。

Answer 1

此问题可能是由于您的代码和Boost.Log之间的目标Windows版本不匹配造成的。见这个答案：

60 with MinGw on Windows 7

很可能，您的项目在某个地方将_WIN32_WINNT定义为0x0600或更高的值。

当由MinGW编译时，Boost默认为Windows，因为MinGW提供的Windows太不完整了。
