我的项目使用 Visual Studio 2012，我使用的是来自他们页面的 libfftw-3.3.lib。 当我在调试中构建我的项目时，它链接和编译都很好，我得到了一个工作应用程序。 当我将它设置为 Release模式时，链接器给我以下错误:
2>LINK : fatal error C1047: The object or library file '../IncludeLibs/libfftw-3.3-x86.lib' was created with an older compiler than other objects; rebuild old objects and libraries
2>LINK : fatal error LNK1257: code generation failed
当我将我的项目设置为输出 .lib 时，即使在 Release模式下，它也能工作，但不是 .dll 或 .exe
知道发生了什么，或者我能做些什么来解决这个问题？
编辑: 我的链接器设置，调试:

最佳答案
在发布配置下右键点击你的项目 配置属性->常规->全程序优化->“无全程序优化”
您的链接库可能没有启用LTCG 优化，VS2012 无法使用/LTCG 优化您的程序。
