c++ - 错误 LNK2038 : mismatch detected for '_MSC_VER' : value '1600' doesn't match value '1700' in CppFile1. 对象

Question

我正在将我的项目从 VS2010 转换到 VS2012。但是我在某些项目中遇到了 _MSC_VER 链接器错误。经过长时间的谷歌搜索后，我发现问题是由于将 VS2010 中创建的库链接到 VS2012 造成的。

如何找出导致错误的项目？这里我引用错误:

TL;DR; 使用当前编译器(VS2012，在 OP 的情况下)重新编译所有旧的 static-linked .lib 文件。

---

您正在尝试链接由不同版本的编译器编译的对象。这在现代版本的 VS 中不受支持，至少如果您使用的是 C++ 标准库则不支持。标准库的不同版本是二进制不兼容的，因此您需要链接器的所有输入都使用相同的版本进行编译。确保重新编译所有要链接的对象。

编译器错误命名了涉及的对象，因此问题的信息已经有了您正在寻找的答案。具体来说，您链接的静态库似乎需要重新编译。

所以解决方案是用VS2012重新编译Projectname1.lib。

You can link to older .lib files only if:

• If they are not static-linked, and come with an already compiled .dll file (or .exe file).
• Or if the two standard-libraries are binary-compatible (which they are not in OP's case).
