链接错误尝试CS106B

时间：2010-08-12 07:06:17

标签： c++ visual-studio-2008 linker-errors

我尝试启动一个空白的VS2008项目并跟随讲座中输入的内容，但我遇到了一堆可怕的链接错误。在用于PC的分配1的zip文件中，有一个名为CS106B的文件夹。 首先我告诉编译器头文件在哪里（它们在CS106B文件夹中）。

接下来，我必须告诉链接器使用CS106CPPLib.lib。好的，这是标准程序...... 但我无法对出现的错误做出正面或反面。

以下是课堂上的代码（讲座4 iirc）

#include "genlib.h"
#include <iostream>
#include <fstream>
#include "simpio.h"

int main()
{
 ifstream in;
 cout << "Enter name: ";
 string s = GetLine();
 in.open(s.c_str());
  if(in.fail())
   Error("File didn't open");
 return 0;
}

以下是产生的错误：

我是Visual Studio的新手，非常感谢帮助。

编辑：在VirtualBox VM中运行OSX，我使用XCode在几分钟内运行了这个精确的程序。缺点是VM无法全屏显示且相对较慢。

看起来像一个不兼容的库。

您添加的库定义了一些通常由编译器库提供的​​符号：

1＆gt; msvcprtd.lib（MSVCP90D.dll）：错误LNK2005：“public：class std :: basic_ostream＆gt; * __thiscall std :: basic_ios＆gt; :: tie（void）const”（？tie @？$ basic_ios @DU？$ char_traits @ D @ std @@@ std @@ QBEPAV？$ basic_ostream @ DU？$ char_traits @ D @ std @@@ 2 @XZ）已在CS106CPPLib.lib（genlib.obj）中定义< /强>

我怀疑CS106CPPLib.lib禁止链接器使用VS2008提供的其他库。您应该考虑CS106CPPLib.lib与VS2008不兼容。

答案 1 :(得分：0)

如果没有看到您的entire Project settings，就很难准确回答。

可能this可能对您有所帮助。

同样仔细检查包含的库，以确保不会多次包含库。这可能是一个原因。 我猜不过。

答案 2 :(得分：0)

Genlib定义与MSVCPRTD库链接的函数。

您可以尝试通过转到项目属性页面从解决方案中排除MSVCPRTD（在调试中的MSVCPRT中），转到链接器部分的输入选项卡并输入库名称到排除字段（或使用/ NODEFAULTLIB：MSVCPRTD命令行开关）

要检查的另一件事是确保库以相同的模式（/ MT或/ MD）编译。我不知道genlib（CS106CPPLib）中定义了什么，所以在你的情况下，排除内置库可能不起作用，但是值得一试。

答案 3 :(得分：0)

确保您的测试项目 Configuration Properties > C/C++ > Code Generation > Runtime Library: Multi-threaded Debug (/MTd) or Multi-threaded Debug DLL (/MDd).。与gtest项目设置相同。
