C ++ / CLI DLL项目从VS2008转换到VS2010后停止链接 [英] C++/CLI DLL project stops linking after conversion from VS2008 to VS2010

问题描述

我转换了一个完美的工作Managed C ++ DLL项目，它使用Unmanaged C + + LIBs从VS2008到VS2010。之前我用VS2010单独重建了LIB（它们是我没有权限的另一个项目的一部分）。但是，转换后，我的托管DLL项目停止链接，给我几个LNK2001错误消息（见下面的示例）。关于string和iosfwd标题中定义的std实体的所有错误。我缺少哪些编译器/链接器设置？

I converted a perfectly working Managed C++ DLL project that uses Unmanaged C++ LIBs from VS2008 to VS2010. Beforehand I separately rebuilt the LIBs with VS2010 (they are part of another project that I have no authority over). However, after conversion my managed DLL project stopped linking giving me few dosen of LNK2001 error messages (see the sample below). All errors about "std" entities defined within "string" and "iosfwd" headers. Which compiler/linker settings am I missing?

感谢您的帮助。

推荐答案

最后找到它（感谢Hans Passant的提示！）我有一些文件，仍然是由VS2008构建的，导致的问题。感谢大家谁打扰添加评论。

Finally found it (thanks Hans Passant for the tip!) I had a few files that were still built by VS2008 and that caused the issue. Thanks to everyone who bothered to add a comment.
