同样，当我尝试在32位主机上使用MinGW-builds编译64位程序时:

T:mingw32>.bing++ -m64 Test.cpp
我

: 

Test.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in
 #include <iostream>
 ^

mingw构建不应该是双目标吗?

我错过了什么?

对于那些使用mingw在linux上得到此链接器错误的人，您可能正在尝试使用64位编译器构建32位二进制文件，带有-m32标志或其他方式。

要解决这个问题，只需编译i686-w64-mingw32而不是x86_64-w64-mingw32。

尽管MinGW-w64 Wiki上的通用使用说明页面声称MinGW-builds项目提供双目标编译器，但这已经不完全正确了。SEH变体(从GCC 4.8.0开始)只是单目标的。您可以通过检查其发行版的目录结构自己看到这一点，也就是说，它们只包含64位或32位寻址的库，而不是两者都包含。此外，最近它在MinGW-builds的邮件列表中得到了确认。

另一方面，普通的旧SJLJ发行版确实是双目标的。如果你得到:

应用程序无法正确启动(0xc000007b)。单击OK关闭应用程序。

运行这些发行版生成的64位应用程序时，您应该记得0xC000007B是STATUS_INVALID_IMAGE_FORMAT的代码，这是64位应用程序试图加载32位dll的一个很好的证据。可能，您已经将bin添加到PATH，而为了64位应用程序的正常运行，应该添加i686-w64-mingw32lib64。
