使用boost :: filesystem时链接器错误？

我有以下代码:

#include 
#include 

int main(){
    const char* file_path = "my_path";
    std::cout << boost::filesystem::file_size(file_path) << std::endl;
}

当我构建时,我得到以下错误:

1>Main.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAAEBVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'native_ecat''(void)" (??__Enative_ecat@system@boost@@YAXXZ)

我正在使用Visual Studio,我已经为我的链接器设置了额外的库路径"C:\Program Files\Boost\boost_1_54_0\stage\lib;".我也设置了包含路径来查看C:\Program Files\Boost\boost_1_54_0;

有人可以帮忙吗？当我使用boost :: algorithm,boost :: string和boost :: interprocess时,我的代码构建正常.

编辑:这是我在命令行上完成的链接如下所示:

我在Visual Studio中构建了类似的未解析的外部.
解决方案是将使用wchar_t设置为内置处理.
