我有一些C ++代码，在32位Windows XP上生成一个DLL。在64位Windows 7下移植项目，我只获取目标文件，但没有DLL，也没有错误消息。
除Windows版本外，两个系统中使用的工具大致相同：
makefile和CodeBlocks的配置文件是相同的。
我在Windows XP上从gcc获得的警告无关紧要。 这些是我在Windows 7上从gcc获得的警告，它们似乎没有相关性：

让我感到惊讶的是，我没有得到任何关于没有生成DLL的事实的错误（我确实在整个硬盘上查找它，以防它放在其他地方）。
就像连接器根本没有被调用一样......
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误。
感谢您的任何提示！
