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 Studio作为我的生成器从Visual-Studio开发人员控制台构建它，我可以构建得很好。但是在我的MinGW32环境中，我遇到链接器错误。我可以确认在我的mingw32环境中安装了boost，并且适用于其他项目（使用其他boost组件）。

我建立：

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

这是输出

我的设置有什么问题？

注意：我已经检查过（并尝试过）这些链接以防我的问题重复：

Mingw32 Boost Log Link Errors: InterlockedCompareExchange（迁移问题）
boost log link error 2019（BOOST_LOG_DYN_LINK问题）
Boost-log linker error（Unicode问题）
link error with boost log（Unicode问题）
Visual Studio 2013 Boost-log v1_61_0 linking errors（提升安装问题）

如果我查看这些解决方案，unicode one是唯一一个我没有工作的解决方案。我已将add_definitions("-Zc:wchar_t")添加到我的Cmake文件中，但是我从c ++。exe中得到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

问题可能是由于代码和Boost.Log之间的目标Windows版本不匹配造成的。看到这个答案：

Problems Linking boost log 1_60 with MinGw on Windows 7

您的项目最有可能将public function method() { ... return view('example')->with(['variables'=>'VARIABLE TEXT']); //example refers to example.blade.php //eg: yourpage refers to yourpage.blade.php //with subdirectories: foo.bar refers to foo/bar.blade.php }定义为值_WIN32_WINNT或更高。

由MinGW编译时，默认为Windows XP，因为MinGW提供的Windows SDK太不完整。

提升日志链接错误（Cmake Mingw32）
