c++ - 使用#define NDEBUG 给我 C++ 中的错误

Question

如果我在 main.cpp 的顶部定义 NDEBUG，我会得到所有这些错误:

1>  All outputs are up-to-date.
1>libcmt.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already defined in LIBCMTD.lib(invarg.obj)

我正在使用 MS Visual Studio 2010、boost 和 gosu 库。

Answer 1

这很可能是由于包含的 header (如果您定义了 NDEBUG，则为发布版本)和链接库(看起来是调试版本)之间的不匹配造成的。也许某些 header 依赖于自动链接功能，因此您可以链接不同版本的库。
