visual-studio-2012 - 如何修复 Visual Studio 2012 错误 LNK2019:无法解析的外部符号“__declspec(dllimport) public: class std::basic_string?

Question

如何修复 Visual Studio 2012 错误 LNK2019:未解析的外部符号“__declspec(dllimport) public: class std::basic_string?

我一直在编译一个包含一个 exe 和几个静态库项目的解决方案
exe 依赖于 Visual Studio 2008。静态库包括:

TCL:tcl84tsx.lib

wxWidgets: wxbase.lib

zlib.lib

ws2_32.lib

xerces-c_2.lib

SNMP 研究 EMANATE: subagent.lib,agent.lib,emanate.lib,pack.lib,mibtable.lib,devkit.lib

等

我将解决方案加载到 Visual Studio 2012 中并编译了解决方案中的所有项目，但是当我尝试链接 exe 时，我收到有关标准 C++ 库中未解析符号的错误，如下面的输出。

我发现很多人都有像这样的未解析符号，但没有一个修复对我有用。到目前为止我尝试过的修复包括

通过手动添加对 exe 项目所依赖的静态库项目的引用来更新 EXE 项目

切换“将 wchar_t 视为内置类型”链接器选项

Visual Studio 2012 链接器的输出...

Answer 1

在properties->c/c++->Laguage 中，我将treat wchar_t as built in type 设置为No，它解决了我的问题。
