从 Windows XP 迁移到 Windows 7 时无法再生成 DLL

Question

我有一些 C++ 代码，可以在 32 位 Windows XP 上生成 DLL。在 64 位 Windows 7 下移植该项目，我只得到目标文件，但没有 DLL，也没有错误消息。

除了 Windows 版本外，两个系统中使用的工具大致相同：

• WinXP 上为MinGW
• gcc 3.4.5，Win7
• CodeBlocks 10.05

上为 gcc 4.6.1 makefile 和 CodeBlocks 的配置文件是相同的。

我从 Windows XP 上的 gcc 收到的警告不相关。 这些是我从 Windows 7 上的 gcc 收到的警告，这些警告似乎也不相关：

令我惊讶的是，我没有收到有关无法生成 DLL 的事实的任何错误（我确实查找过它）在整个硬盘上，以防它被放置在其他地方）。

就像根本没有调用链接器一样...

在 Windows7 上创建一个单独的虚拟项目我得到了 DLL。所以这不是工具的错。

谢谢您的任何提示！
