同样，当我尝试编译一个32位主机<一个在64位程序href=\"https://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0/32-bit/threads-win32/dwarf/\">MinGW-builds:

  T：\\ mingw32的＆GT; \\ BIN \\ g ++的-m64 Test.cpp的
 

我得到：

  Test.cpp的：1：0：对不起，没有实现：64位模式没有被编译
 ＃包括LT＆;＆iostream的GT;
 ^
 

是不是的MinGW，建立应该是双目标？

我是什么失踪？

解决方案

虽然在的一般使用说明 上的MinGW-W64 Wiki页面声称，在的 MinGW的-建立 项目供应双目标编译器，这并不完全正确了。该变种SEH（它们来自GCC 4.8.0开始）只有单一目标。您可以通过检查其分布的目录结构，你自己看出来的，即它们只包含有两种64位或32位寻址的库，但不能同时使用。此外，最近证实的邮件列表上的MinGW-的基础之上。

在另一方面，普通的旧SJLJ分布确实双靶。如果你得到：

  

应用程序无法正常启动（0xc000007b）。
  单击确定关闭应用程序。

运行由这些分布产生的6​​4位应用程序的时候，那么你应该记得， 0xC000007B 是code STATUS_INVALID_IMAGE_FORMAT ，这是一个很好的证据表明，64位应用程序试图加载32位的DLL。也许，你已经添加 \\ BIN 到 PATH ，而应该补充 \\ i686的-W64 -mingw32 \\ lib64的 64位应用程序的正常运行。

When I try to compile a 32-bit program on a 64-bit host with MinGW-builds:

T:\mingw64>.\bin\g++ -m32 Test.cpp

I get:

Similarly when I try to compile a 64-bit program on a 32-bit host with MinGW-builds:

T:\mingw32>.\bin\g++ -m64 Test.cpp

I get:

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

Aren't MinGW-builds supposed to be dual-target?

What am I missing?

解决方案

Although the General Usage Instructions page on MinGW-w64 Wiki claims that the MinGW-builds project supplies dual-target compilers, this is not completely true anymore. The SEH variants (which come starting from GCC 4.8.0) are only single-target. You can see it yourself by inspecting the directory structure of their distributions, i.e. they contain only the libraries with either 64- or 32-bit addressing, but not both. Furthermore, recently it was confirmed on the mailing list of MinGW-builds.

On the other hand, plain old SJLJ distributions are indeed dual-target. If you get:

The application was unable to start correctly (0xc000007b). Click OK to close the application.

when running the 64-bit application produced by these distributions, then you should recall that 0xC000007B is the code of STATUS_INVALID_IMAGE_FORMAT, which is a good evidence that 64-bit application is trying to load 32-bit DLLs. Probably, you have added \bin to PATH, whereas should have added \i686-w64-mingw32\lib64 for 64-bit applications to run properly.
