Visual c++ 构建解决方案时出现LNK2019错误
我正在尝试使用Visual Syudio 2010中的OpenHaptics库编译一个示例代码。我通过Visual c++ 构建解决方案时出现LNK2019错误,visual-c++,linker-errors,lnk2019,Visual C++,Linker Errors,Lnk2019,我正在尝试使用Visual Syudio 2010中的OpenHaptics库编译一个示例代码。我通过projectproperties->Linker->Input链接了多线程C-runtime和库。还包括目录。file.dll位于系统文件中。但当我尝试构建时,同样的错误会出现 Haptics.obj : error LNK2019: unresolved external symbol __imp__hlEndFrame@0 referenced in function "void __cd

我安装了Visual C++ 2008 Express版,并举例编译。
除非您必须创建发布代码而不是调试。
这不是一个真正的解决方案,但它似乎有效。好的,我尝试在Windows XP上运行它,它起到了帮助作用,但没有那么大,出现了一个新错误:hdu.lib(hduError.obj):错误LNK2019:未解析的外部符号“\u declspec(dlliport)public:int\u thiscall std::basic\u streambuf::sputn(char const*,int)”(uu imp?sputn@?$basic)_streambuf@DU?$char_traits@D@std@@@std@@QAEHPBDH@Z)在函数中引用"class std::basic_ostream&u cdecl std::operatorMant我要说的是,我在Windows 7中完成了所有这些。谢谢Tim。深入研究错误后,我发现OpenHaptics教程在库方面并不完整,需要将一些额外的库链接到该项目才能正常运行。但是,一些教程中的ER与我使用的软件(Windows7上的MVS Express 2010)不完全兼容,但最终我无法使用需要这些特定头的方法。
