Question

我有一个使用IBPP访问firebird数据库的C ++项目。我只是通过在我的项目中包含文件“all_in_one.cpp”来完成它，并且VS6（是的，我还有一些）和VS2008都很顺利。

现在我正在考虑使用VS2010。它编译正常但没有链接。我知道VS2010带有一个新的STL实现，链接问题显然是围绕STL。

我尝试使用VS2010创建一个新项目，只需添加all_in_one.cpp文件。这是一个不包含任何其他内容的简单项目，但仍然无法与相同的缺失符号链接。我无法弄清楚缺少什么，不正确。我尝试链接到VS2008中的相同库（包括路径）。到目前为止，没有任何工作。

以下是错误：

Answer 1

您的库/ DLL似乎正在导出一些模板化/ STL内容。

STL在不同的编译器版本之间不是二进制兼容的。

如果涉及STL /模板，则需要使用相同的编译器/链接器/位来编译和链接DLL / EXE。

Answer 2

从构建中删除all_in_one.cpp并使用core中的其他文件来构建库。

Answer 3

关于上面错误列表中的链接器错误10和11，我有以下解决方案（可能它修复了所有错误）。

在解决方案资源管理器中右键单击项目并选择“属性”，打开项目的属性页。

在“物业页面”内 - 窗口：

-->  open "Configuration Properties" from left menu
     --> select "VC++ Directories" on the left
         --> go to "Library Directories" on the right
             --> the corresponding string should contain a sub-string like
                 "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib"
                 --> replace "9.0" by "10.0"

使更改正常“重新”构建您的解决方案（可能首先清理您的解决方案）。
